Unconfirmed "Numbers" Trivia

Card Name
 Trivia

Number F0: Future King Hope 
 This card's number matches its Rank, ATK, and DEF.
 The number 0 is a number that is not part of the positive range of numbers. Similarly, this card is not a part of either the Emperor's Key Numbers or the OverHundred Numbers (both of which are represented by positive numbers), instead being a completely unique Number created by Yuma during his final Duel with Astral.
 0 is also a number associated with emptiness or nonexistence, relating to Yuma's claim that the possibilities of both the future and this card, which is Rank 0, have yet to be decided (and thus do not exist yet).
 0 resembles the English letter O, which is the only English letter used in ō, the Japanese word for "king". This may be a reference to the entire "Hope" Archetype, every member of which has "King" in their Japanese names.

Number 1: Infection Buzz King 
 The number 1 is often considered to be symbolic of superiority, or "being at the top". Appropriately, this card's effect allows it to absorb other "Number" monsters by attaching them to this card as Materials, signifying its status over the other "Numbers".
 By the same token, Mr. Heartland, this card's chief owner, is the leader of the Fearsome Four of the Dark Dueling World, which further buffers this view.
 Another coupling with Mr. Heartland is one Japanese translation of the number 1 (ichi), which translates to "fair". Used as a noun, a fair is a public gathering where usually either things and/or services are showcased or where there's associated carnival or funfair entertainment. In the context of the anime, Mr. Heartland was the Master of Ceremonies of the World Duel Carnival, whose sole purpose was for Mr. Heartland to acquiesce as many "Number"s as possible. Moreover, likewise as previously stated, this card's effect in part, absorbs "Number"s for its own use.
 In the anime, this card's number matches the original Levels of the monsters Mr. Heartland (this card's chief owner) used in Summoning this card, which were three Level 1 "Infection Flies".

Number 1: Gate of Numeron  Ekam 
 This card's number matches its Rank.
 This card's name, Ekam, is Sanskrit for "one", matching the numerical value of this card.

Number 2: Ninja Shadow Mosquito 
 The number matches this monster's Rank.
 If you take this card's Rank (2) and add it to the number of Xyz Materials required to summon this card (3), you get 5. This number alludes to Quinton (whose Japanese name is V, the roman numeral for 5), who faces this card along with Kite.
 In Japanese, the number 2 (ni) inpart translates to "red". This may be coupled with the following:
 This monster resembles a mosquito; the said organism's most wellknown provender (food) is mammalian blood; such blood is red in color due to the metalloprotein substance hemoglobin present within it.
 The 2 may also insinuate the "double whammy" of harm that mosquitoes inflict upon their host during feeding, as they not only sap their blood supply but can also transmit pathogenic disease vectors to their host, if any are within the mosquito.
 All of Scritch's (this card's owner)'s monsters, including this one, bear redhued characteristics on their bodies. "Mosquito Force" and "Mosquito Commando" sport redcolored abdomens and this card has a violetred mouthpart and is carrying mostly reddish winged appendages on its arms.
 Even more interesting is that this card is carrying 2 such appendages (of which the one on the right bears this card's "Number") and "Mosquito Commando"'s abdomen is bisected (split into 2 different segments)
 Red is also the most ascendant color of this card's Hallucination Counters (per its effect.)
 If you reverse 02, you get 20, which is the number of "GigaBrilliant", which was formerly one of the "Number"s of Kite Tenjo, who is this "Number"'s current owner.
 Fittingly, the appearances of both "GigaBrilliant" and this "Number" take after insects.
 Still with Kite, the 2 may also signify this being the second "Number" card he obtained since the Legendary Number War arc commenced, the first being "Number 46: Dragluon"
 Moreover coincidentally, if you reverse the said Number's digits and then subtract them (64) you get a difference of 2, the same value as this "Number's".

Number 2: Gate of Numeron  Dve 
 This card's name, Dve, is Sanskrit for "two", matching the numerical value of this card.

Number 3: Cicada King 
 The number matches this monster's Rank.
 The number also matches the number of Xyz Materials required to Summon it.
 This card's original ATK is a multiple of this card's number, as 1200 / 3 would equal 400.
 The number 3 (san) in Japanese translates inpart to the honorary titles, "Mr." or "Mrs." This might pertain to the fact that this card's chief owner Erazor, is the first revealed underling of the Fearsome Four of the Dark Dueling World, whom are Mr. Heartland's underlings.
 As this card resembles a cicada, which is an insect, this "Number" might pertain to the three chief bodily segments insects have: Head, Thorax and Abdomen.
 Erazor, this card's initial owner, used 2 other monsters whose appearances take after cicadas, which is what this card resembles: "Oily Cicada and "Dream Cicada", he thus used 3 distinctive "Cicada" monsters in this "Number"'s debut Duel.
 Even more jarring is the fact that he also used 3 Trap cards (all three were also "Cicada" support) in the same Duel.
 Oddly, in this card's debut Duel, all of the other "Number" cards this card opposed had multiples of 3 in each of their digits (Yuma Tsukumo used "Number 39: Utopia" and Trey used "Number 33: Chronomaly Machu Mech" plus "Number 6: Chronomaly Atlandis".)
 This card's numerical value could also reference the fact that it was first used onscreen against Trey.
 It also references Trey's codename (III).

Number 3: Gate of Numeron  Trini 
 This card's name, Trini, is Sanskrit for "three", matching the numerical value of this card.

Number 4: Stealth Kragen 
 The number matches this monster's Rank.
 This card's numerical value could reference the fact that it was first used onscreen against Quattro.
 The number 4 (shi) in Japanese inpart, translates to "luxury" or "extravagance." This may refer to the fact that this card's debut Duel takes place just outside of the Kastle's mansion, which is an derelict, albeit also once the aristocratic living quarters of Reginald Kastle, one of the Duel's participants.
 This translation may also be reflective of Dueling participant Quattro, whose attire is somewhat aristocratic and whose past involved success and eminence due to his professional tournament triumphs.
 Chironex, this card's initial owner, used 3 other monsters whose appearances take after jellyfish, which is what this card resembles: "Silent Sea Nettle", "Stinging Jellyfish" and "Kragen Spawn"; he thus used 4 distinctive jellyfish monsters in this "Number"'s debut Duel.
 Even more jarring is the fact that he also used 4 Spell/Trap cards in the same Duel.
 This card's number could be a reference to the fact the fact that it's original owner, Chironex, is a member of the Fearsome Four of the Dark Dueling World.
 The number of this card corresponds to it's last owner, Quattro (IV).
 Moreover, if you reverse 04, you get 40, which is the number of "Gimmick Puppet of Strings", which is not only another "Number" now currently owned by Quattro but it was also used in this "Number"'s debut Duel and its numeric value also strongly allude to his said moniker.

Number 4: Gate of Numeron  Catvari 
 This card's name, Catvari, is Sanskrit for "four", matching the numerical value of this card.

Number 5: Des Chimera Dragon 
 While this "Number" was not actually played or shown, This card's number matches its Rank.
 This card's Number is the total representation of the combined power of five of the Seven Barian Emperors (Dumon, Merag, Gilag, Alito, and Vector) that Vector had when he Duels Nasch.
 In the duel that this card was named in, Vector summoned a total of five Xyz Monsters, "Number C65: King Overfiend", "Number C102: Fallen Seraph  Noble Archfiend", "Number C103: Ragnafinity", "Number C104: Umbral Horror Masquerade", and "Number C5: Chaos Chimera Dragon.
 The number 5 (gō) in Japanese inpart, translates as "honorable". This may relate to the revelation of Vector's childhood, which was revealed after this card's debut Duel, of which at one point, Vector wished to broker honorable peace treaties with every belligerent faction that was at war with his late father's until Don Thousand influenced him to be more like his pugnacious, warring father.

Number 6: Chronomaly Atlandis 
 The 6 can be read as "roku", which has identical pronunciation as "rock", reflecting this monster's rocklike stature.
 It is the 2nd Number used by Trey that is related to his own archetype (first being "Machu Mech", not counting "Shark Drake", which is not a "Chronomaly" monster), so going by the fact his name is III in the original version of the anime, the formula reads 3 x 2 = 6.
 The Number matches this monster's Rank.

Number 7: Lucky Straight 
 7 is considered to be a lucky number, and in gambling games it is most commonly used as the charm number, which reflects this card's ability to amplify the user's luck.
 The number 7 matches its Rank, and it matches the needed dice value to activate its effect, as well as reflects its ATK and DEF stats of initially 700 each.;
 There appear to be 7 different colors on this card's artwork.
 Likewise, reflecting its dicerolling effect and gamblingtheme, the total sum of the values of any opposite sides of a die equal 7.

Number 8: Heraldic King GenomHeritage 
 Given its genometheme, the shape of the number 8 itself resembles a double helix of a DNA molecule.
 Likewise, the same theme is reflected by how the DNA molecule consists out of 2 long strings and is made out of 4 different nucleic acids, so: 2 x 4 = 8
 While Number 69 reflects Vetrix's link to Trey and Quinton by taking their single Numbers, this monster's Number reflects his relation to Quattro, bearing the one digit of his otherwise two digit ace monster.
 This card's number, 8, also relates to Quattro: since he goes by the name IV in the Japanese version, 2 * 4 makes 8, a reference to this card's number.
 This may be strengthened by this card's arguably draconian effect in the Anime that pilfers a monster's name, stats and appearance, which could mirror Quattro's former callousness during some of his Duels (hence his predominantly macabre "Gimmick Puppet" Deck.)
 While the number does not match its Rank like most single "Numbers", it does match the total Level Star requirements for needed monsters in its Summon (2 Level 4 monsters; 2 * 4 = 8).
 In reference to the number of "Heraldic" monsters, Vetrix used 8 members of the archetype, including this monster.

Number 9: Dyson Sphere 
 Being arguably the most powerful Number used among Vetrix's sons, being used by its eldermost brother, the number 9, when written in Roman numbers, bears the codenames of all three of them:
 By crossing the last two Is in III, one can form an X, getting the Roman number IX, reflecting Trey;
 By combining the Vs in Quattro's and Quinton's codenames together in their tips, one can get an X, and together with the I in Quattro's name, again form the IX;
 In addition, the number 9 can be viewed as the squared value of 3 (reflecting Trey), or the total sum of 4 and 5 (Quattro's and Quinton's codenames);
 The word "Sphere" in the Japanese language is 球 (kyū), which has the same pronunciation as the number 9.
 The number matches the monster's Rank.

Number 10: Illumiknight 
 10 is the atomic number for Neon in the Periodic Table of the Elementsneon is a gas used in industry to create neon lights, reflecting this monster's luminous appearance and theme;
 Further adding to this is the later introduction of this card's DARK Counterpart by Don Thousand: "Number 10: Dark Illumiknight", which could refer to the fact that as with all lights, neon ones can be turned off; or, perhaps, a black light also.
 Still with this card's Fake Number reference as "Dark Illuminknight", in retrospect, 10 might be the sum of all the other known Fake Numbers so far. (4 + 3 + 2 + 1 = 10)
 Since Kite Tenjo primarily used "Numbers" divisible by 10, this number matches this by being the first number used by him on screen.
 The word "shiro" in this card's OCG name, that means "white", is made out of "shi", that means 4, and "ro", which stands for 6. Adding 4 and 6 together gives off the result of 10.

Number 11: Big Eye 
 This is the 11th Number introduced in the anime;
 This card's number can be written in Roman Numerals as "XI", which can be interpreted as "Big (X) Eye (I)".
 Rolling double 1's with a pair of dice is often considered an unlucky roll, referred to as "snake eyes." In the Old Testament of the Bible, a snake was the animal that persuaded Eve to eat the Forbidden Fruit, matching the name of Big Eye's effect: "Temptation Glance."
 In Numerology, the Number 11 is one of the strongest numbers, holding great spiritual powers and awareness of the paranormal.

Number 12: Crimson Shadow Armor Ninja 
 The two pieces of armor on this monster's thighs resemble the generic number 6. When added together, both of these equal to 12.
 This monster seems to be a reference to the Akakage, The Masked Ninja tokusatsu series. "Akakage" (赤影) literally means "Red Shadow", to which this card's name might refer to. Also, in the 12^{th} episode of the anime series, a ninja wearing an unbreakable armor appears. This monster's numerical value and effect could refer to it.
 In the Anime, this monster is the 1st and only "Number" its original owner Kaze Summoned in his Duel with Yuma and the 2nd "Ninja" monster he Xyz Summoned.

Number 13: Embodiment of Crime 
 The Number may be a reflection of this monster's thematical background, being based on the Biblical story of Cain and Abel. According to Genesis 4:18, Cain committed the first murder by killing Abel. The sum of all these is 4+1+8 = 13.
 As 13 is often considered to be the number of ill fortune, this monster takes the role of Cain, the aggressor, instead of Abel, the victim. This also reflects the ill fortune both monsters bestowed upon Kaito and Shark during their debut.

Number 14: Greedy Sarameya 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin".
 Incidentally this was the 2nd "Number" monster that Kyoji Yagumo summoned and 7x2=14.
 This card is a reference to one of the Seven Deadly Sins, "Greed".

Number 15: Gimmick Puppet Giant Grinder 
 This is the first Number used by Quattro, and reflects his Japanese codename, IV; If each of the letters in the codename is read separately, the result is 1 and 5, which matches the Number.
 Still with Quattro, the numeric values of the main "Number"s used by his brothers Trey (6) and Quinton (9) if added, would equal 15, which matches this "Number"'s value.
 15 may be reflected by how this monster has 1500 ATK.

Number 16: Shock Master 
 In Japanese, the number 1 can be read as "i" and 6 as "ro"; together, it reads "iro", the Japanese word for color, which makes sense for the monster called "Ruler of Color" (in Japanese).
 If you take the square root of 16, you get 4; this number matches this card's Rank value and the Level requirements of its Xyz Material.
 Furthermore, 16 would also be the sum you would get if you add the total values of the Levels of the 3 required monsters with the value of this card's Rank.

Number 17: Leviathan Dragon 
 Coincidentally, this card is the 17^{th} released Ghost Rare monster.
 If you reversed this card's digits and then subtracted them (7  1) you would get 6 as the difference and come to the following suppositions:
 6 is the sum of the Levels needed for this card's Xyz Summon.
 6 might reference the 6 wings of this monster as well as the six large spikes (three on each side) near this monster's tail.
 Separately, this "Number"'s digits may both intimate this card's debut Duel too, of which the order of the seperate digits play out as that Duel goes on:
 The 1 may connote to this card being the first "Number" card that was shown and played in the anime.
 The 7 may allude to the sum of the combined Ranks of this card as well as the only other Xyz Monster that was later used in its debut Duel, which by happenstance, is also a "Number", "Number 39: Utopia" (3 + 4 = 7).

Number 18: Heraldic Progenitor PlainCoat 
 The 1 in this card's name references "Heraldic Beast Amphisbaena" (a card that was not shown in Vetrix's Deck), while the 8 represents the other 8 "Heraldic Beast" monsters Vetrix used.
 Still with both digits coupled with the "Heraldic Beast" insinuations, add two "0"s after the 18 and you get 1800; this is by happenstance, the ATK of Vetrix's first seen "Heraldic Beast" in the anime, "Heraldic Beast Aberconway".
 In Japanese, the number 8 (hatsu) inpart, translates as "beginning". This supports the "Heraldic Progenitor" part of this card's name as well as perhaps also this card's appearance, as it looks like a more primeval version of "Heraldry Crest".
 Coincidentally, the digit that proceeds the 8 happens to be a 1, which is the numeric digit often associated as being the "beginning" number (not counting zero, as it connotes as being a nonvalue digit), further supporting this interpretation.
 Even furthering the "beginning" part, the 8 by itself may also advert to the number of "Heraldic King Genom Heritage", which is the first "Number" Vetrix uses in the anime.

Number 19: Freezadon 
 This monster is the polar opposite of "Number 61: Volcasaurus", in terms of attribute, effect, stats, and the Number, which is the upside down read of Volcasaurus' 61.

Number 20: GigaBrilliant 
 This is the 2nd "Number" used by Kite, as well as being the 2nd number divisible by 10, which was initially a trademark for Kite's "Number"s.
 This monster resembles an ant, which inturn is an insect. Insects are normally partitioned into three main bodily components a head, thorax and abdomen. "GigaBrilliant" clearly appears to have the former two segments while lacking an noticeable abdomen; the 2 may thus come from the fact that this Insect has two out of these three insect body parts.

Number 21: Frozen Lady Justice 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin".
 Incidentally this was the 3rd "Number" monster that Kyoji Yagumo summoned and 7x3=21.
 Coincidentally, this card is a slight reference to one of the Seven Deadly Sins "Wrath or Anger.
 This is because Anger can manifest as revenge, which goes with the saying "revenge is a dish best served cold." Hence the ice motif that goes with this monster. Also, "to bring justice" is quite commonly used as reason for revenge.
 Based on its effect, this card could also be a reference to the sin of Gluttony.

Number 22: Zombiestein 
 This monster seems to be based on Frankenstein's monster, which, in the second published edition of Frankenstein by Mary Shelley, was published in 1822. This links both to this card's Number and the chapter of the manga where its skills and weaknesses were revealed.
 One can say "two 2's" (22) in Japanese by saying "fu ni"; this could be a pun on "funiku" (腐肉), which means "tainted meat", which could be an implicit metaphor for an undead being, such as this being a ZombieType monster.

Number 23: Lancelot, Ghost Knight of the Underworld 
 If one reads 2 as "fu" and 3 as "san", it forms the word "fusan" (不参), which means "absence" or "nonappearance". This may refer to this monster being a "spirit from the underworld".
 Despite not being divisible by 7, it is possible that this card is a reference to the Seven Deadly Sins.
 In particular, it could be a reference to the sin of Lust or Pride due to Lancelot's love affair with King Arthur's wife, Queen Guinevere.

Number 25: Force Focus 
 This possibly links to 1925, the year in which the first Leica Camera, the first 35mm camera, was introduced to market. The monster itself resembles one.
 2 can be read as "fu", and the first consonant of all 4 words of this card's full Japanese name (Fullmetal Photoglide  Focus Force) are pronounced as either "Fu" or "Fo", therefore, including the 2, there are a total of 5 "F" in the name, hence 25.

Number 28: Titanic Moth 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin".
 The number two can be read as "tsu" and the number eight can be read as "ya". If read together, they spell "tsuya", which can mean youthfulness, love, and feeling. These reflect Haruto's original personality before his soul was lost.

Number 30: Acid Golem of Destruction 
 This is the third Number used by Kite on screen, fittingly being the 3rd by 10 divisible number, like those used by Kite previously were as well.
 The 3 in 30 most likely reflects this card's ATK, DEF, Rank and order of appearance among Kite's Numbers.
 "3", which reflects most of its traits (number, order of appearance, ATK, DEF and rank) can also be read as "san" in Japanese, which is the same pronunciation as "Acid" ("酸, san").
 This card's JUMP release in March 2012 makes it the 30th Xyz Monster released in the TCG.

Number 31: Embodiment of Punishment 
 This monster, as well as "Number 13: Embodiment of Crime", are based on the Biblical story of Cain and Abel, the first and second sons of Adam and Eve. The opposite position of their numbers further allude to this. As does the fact that this card's Number is a flip of its "brother".
 This card and "Number 13" could be the manga's counterpart of "Number 19: Freezadon" and "Number 61: Volcasaurus".

Number 32: Shark Drake 
 In Japanese, the number 3 can be read as "mi" and 2 as "tsu"; together, it reads mitsu, short for Mitsukurina owstoni, the goblin shark, which vaguely resembles this monster's appearance. Mitsu also sounds similar to mizu, the Japanese word for WATER.
 This is the 3rd Number to possess Shark, albeit the 2nd to be strictly in his possession and based on him specifically (the other being "Number 17: Leviathan Dragon").
 Coincidentally, there is a 32 episode gap between the defeat and obtaining of "Leviathan Dragon", the 1st Number to possess Reginald, and his obtaining of this monster as the new ace card.
 The previously mentioned scientific name for the goblin shark, Mitsukurina owstoni, which is what this "Number" vaguely resembles, is (not counting the space inbetween the genus and species strings) 17 characters long, which therefore, may further buttress the hindsight allusion(s) between this card and "Leviathan Dragon".
 This card's numerical value could also refer to it being initially used by Trey and its status as the second Number known to be obtained by the Vetrix Family, after "Number 15: Gimmick Puppet Giant Grinder".
 The number 2 (ni) in Japanese, can be translated as "red"; this could relate to what is the predominant color of this monster as well as the hue of its Number value.

Number 33: Chronomaly Machu Mech 
 This is the 2nd Number used by Trey, and the Number is reflected through his codename III (Trey also means "three" in Middle English) in the original release, hence 33.
 The total value of all digits in this Number equal the Number and the rank of "Number 6: Chronomaly Atlandis", which is the other "Chronomaly" Number used by Trey.
 This is the 3rd Number used by the Vetrix family, being used by Trey whose codename equals the numeral 3.
 A weaker relation here could be that the number 3 by itself can be read as san, which inpart, translates to "sun" in Japanese. Similar to the fact that the sun is found in outer space, this "Number" debuted while the "Photon World" Field Spell Card was in play, which depicts a type of outerspace environment.
 The number 33, as well as the number 24 (2400) and 15 (1500) are multiples of 3, and 3x5 =15, and the number 5 corresponds to the rank of this monster, corresponding to it's owner, Trey (III).

Number 34: TerrorByte 
 The monster this Number is assigned to debuted in episodes 3 and 4 of the YuGiOh! ZEXAL anime.
 This card's number is twice that of "Number 17: Leviathan Dragon", based on the fact this card was the second "Number" monster that Yuma won, not to mention the second enemy "Number" card to debut in the Anime.
 This card's separate numeric digits' Japanese translations may have interpretive insights, too:
 The 3 (san) can inpart translate to "Mr." or Mrs." This could refer to this card's owner Mr. Kay. Although this is his dub name (Professor Ukyo in the original), grade school teachers (whom Mr. Kay is) particularly in the USA, are commonly addressed as "Mr." or Mrs.", followed by their last name.
 The 4 (shi) can inpart translate to "city". While possessed by this "Number", Mr. Kay hacked into and defiled computer systems in Heartland City.
 The 3 in this "Number" matches this card's Rank.

Number 35: Ravenous Tarantula 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin".
 Based on its name, this card could be a reference to the Deadly Sin of Gluttony
 This is the 5th "Number" played by Kyoji and 5x7 = 35.

Number 36: Chronomaly Fork Hyuk 
 The numerical value is double of the same "Number" that was released in Legacy of the Valiant, Number 18. Also, though they are part of the archetypes, neither Vetrix nor Trey were seen summoning these "Numbers" yet.
 As this is a "Chronomaly" card, this card's number also references Trey, (III in the anime,) whose "Numbers" all reference his Japanese name. Both this "Number"s' digits as well as the number as a whole are multiples of 3.
 When individually read in Japanese, the numbers 3 and 6 amalgamate to form "sanroku", which translates as "sun rock". This supports the fact that this card seems to be the power source for "Number 33: Chronomaly Machu Mech", a fellow "Chronomaly" and "Number" that has a very rocklike structure. Also, the city depicted in this card is rocklike and the sphere enshrouding the city seems to glow like a sunsized star; this sphere could easily resemble a sunlike structure without the city in the background, albeit with an azureish glow.
 There were 6 Xyz Monsters who could reduce opponent's monsters ATK to 0 before this card was released. Also, it was the 3rd "Number" monster that is also a part of the "Chronomaly" archetype to be released in the "OCG".
 There were 6 Level 4 "Chronomaly" monsters and 3 Xyz "Chronomaly" monsters before this card was released.
 If you add this "Number"'s seperate numeric digits (3 + 6), you would get a sum of 9. This can be conjugated with the appearance of the bluish globe that mews the structure within it; this globe strongly resembles a Sphere Field, specifically the one that temporarily encompassed Yuma when he thrusts his Emperor's Key into The Door at the very beginning of the YuGiOh! ZEXAL anime series, which inturn interspersed all the other 99 "Number"s that made up Astral's memories into Yuma's world. Ultimately, this card's said sum may connote to that event.

Number 37: Hope Woven Dragon Spider Shark 
 This card's number maybe a reference to Number 73: Abyss Splash, whose Number is the reverse of this card. As both are used by the anime and manga versions of Shark.
 This card's number (37) can be read as "mina", which can translate to "everyone" (皆) in Japanese, reflecting how this Number was created when Yuma, Shark, Kaito, and Kyoji chose to combine forces and battle against E'Rah together.

Number 39: Utopia 
 This card's number (39) can be read as "sankyū", which is the Japanese pronunciation of "Thank you", referencing how Yuma saves people from the "Numbers" (or other dilemmas) and is therefore a hero.
 This card's number (39) can also be read as "miku", which can translate to "future" (未来) in Japanese, relating to this card's Japanese name "Hope" and referencing how Yuma and Astral as ZEXAL are able to perform Shining Draws to pave the way for their own future.
 The 3 alone may be a nod to this card's reallife effect as it can negate two declared attacks against itself (provided its number of Xyz Materials weren't amended by other ways) before it's effect destroys itself if a third attack is volleyed towards itself.
 The 9 on the other hand, might be a reference to its phonetic Japanese name (Kibō'ō Hōpu), not including the space, there are exactly nine characters in the name.
 The 3 in this card's number can be read as san, which is phonetically the same as one reading of the word "sun", referencing Yuma's "sunlike" power to befriend those he Duels.
 Also, this card was originally going to be Number 3.
 Also relating to Yuma, the 9 may relate to his last name, Tsukumo, which can be read as 99.
 The combined values of 39, representing Utopia, and 62, representing Number 62: GalaxyEyes Prime Photon Dragon, gives off 101, representing Number 101: Silent Honor ARK. All the monsters mentioned turn out to be the true ace cards of all 3 main protagonists of YuGiOh! ZEXAL: Yuma, Kite, and Reginald.
 There were 39 Numbers shown in the first season (37 original and 2 "Number C" monsters), hence its numberical value.
 Yuma and Nasch (aka Reginald) used their aces against Don Thousand in 140th episode, which is the sum of their "Numbers", 101 and 39.
 This card's number is sum of all Ranks of "Number C10X" monsters.

Number 40: Gimmick Puppet of Strings 
 This is an evident reference to this Number's owner: Quattro, who goes by the codename "IV" in the original version of the anime.
 If you reverse this card's digits, you would get 04, the number of what would later be "Stealth Kragen". The below elucidations can then be made:
 Peculiarly, in both this card's debut Duel and the Duel where this card faced "Stealth Kragen", this was the last Xyz Monster Quattro Summoned.
 "Stealth Kragen"'s Rank is half of this card's. Its DEF is also half of this card's ATK and DEF.

Number 42: Starship Galaxy Tomahawk 
 Because this card is science fictionthemed, this card's number could be a reference to the spaceoriented scifi novel The Hitchhiker's Guide to the Galaxy, where 42 is the Answer to the Ultimate Question of Life, the Universe, and Everything.
 The number 2 (ni) in Japanese, can be translated as the following:
 "red"this could relate to the fact that this card's OCG artwork features this card producing a noticeable red glow. Moreover, the hue of its Number value is also red.
 "take after (his mother)"In the manga, the "Battle Eagle Token"s this card is able to Summon via its effect strongly resemble this card in appearance; this translation could reflect this, as the Tokens take after the mothership monster (that being this "Number") whose effect Special Summons them.

Number 43: Manipulator of Souls 
 The number 4 can be read as "yo" and the number 3 can be read as "mi". Together they form yomi, which means underworld or Hades. This may refer to Don Thousand (the god of the Barian World) and the Barian World, which absorbs anybody that Don Thousand reincarnates, anyone that has a Fake Number, or anyone that loses to a Barian Emperor.
 This card's number may refer to its Number C form, which requires 4 Level 3 monsters.
 In fact, while neither of this "Number"'s separate digits directly match this card's Rank, both digits do match the Levels/Ranks within Vector's (this card's owner) present and past Decks respectively:
 In the present, the 4 matches the Ranks of some of Vector's other "Number"s (66 and 104;) it also matches the Level predominant in his present Deck archetype, which are the "Umbral Horror" monsters.
 In the past, the 3 matches both the Levels of nearly all of his "Gorgonic" Effect Monsters as well as the Rank of his "Gorgonic Guardian" Xyz Monster (the only one that doesn't match is "Gorgonic Ghoul", albeit this card's digits, if subtracted (4  3) would match its Level, which is 1.) 3 also matches the Level of the "Number C" form of Vector's associated "Legendary Number", which is "King Overfiend".

Number 44: Sky Pegasus 
 44 can be read as "shishi" in Japanese, which could mean "shishi" (志士)  "loyalist", "patriot", possibly referring to how the knight in the legend of this card, protected his land from three other knights who wanted to usurp the king.
 Another weak reference to the number 44 might be the Bénouville Bridge, which was renamed into Pegasus Bridge in 1944, in honor to the emblem worn by the British airborne forces at the time of a liberating operation, which was the Pegasus.
 Not only does 4 match this card's Rank, the 44 could also refer to the fact that this card requires two Level 4 monsters for its Xyz Summon.

Number 46: Dragluon 
 The number 4 can be pronounced as "shi" and 6 as "ro". Together, they form shiro, which means "white", which matches this monster's coloration.
 In respect to this card, along with "Number 39: Utopia" and "Number 32: Shark Drake", which are used by Kite Tenjo, Yuma Tsukumo and Reginald Kastle respectively (the three protagonists of YuGiOh! ZEXAL,) if each "Number"'s numeric values were put in ascending or descending order, each number would be either seven more or seven less than the next one in sequence.
 If you reverse this "Number"'s digits, you get 64, the number of "Sandayu the Vetanuki". Incongruously, in terms of the episodic order of YuGiOh! ZEXAL, this "Number"'s ruins is visited first, followed by "Sandayu's".
 Furthermore, 46 is sequentially less than 64, which is uniform with the episode(s) count when this card's ruins was visited, being less than the episode count when "Sandayu"'s was visited in sequence.

Number 47: Nightmare Shark 
 The 4 in this card's number probably comes from the fact that this card was the fourth Mangaexclusive Number revealed. The 7 in this card's number probably comes from the fact that this card debuted in the month of July which is the seventh month of the year.
 In Japanese, the number 4 can be read as "yo" and the number 7 can be read as "na". If read together with the word "ka", they spell "yonaka", which is the Japanese word for midnight. This references the nightmare part of this card's name.

Number 48: Shadow Lich 
 The number 4 by itself in Japanese can be read as shi, which inpart, translates to "death" or "deceased", which corresponds to this monster being a Lich, which is an undead monster.
 The 8 in this card's number probably comes from the fact that this card was first shown in the August 2013 issue of V Jump as August is the eighth month of the year.
 If you add this card's Numbers separately (4 + 8), you get 12. If you only have this card in your Monster Card Zones and you Special Summon 4 "Phantom Token"s to your Field, their Levels (Ranks in the manga) would total 12 (3 ・ 4).
 Also with the Tokens, if you reverse this "Number's" digits and then divide them (8 ÷ 4), you would get 2; this would also be the maximum count of Tokens you would be able to Special Summon using this card's reallife effect, provided that its amount of Xyz Materials are never revised by other means. Moreover, when this card uses its effect twice for its Tokens, multiplying their total Levels by 2 (6 ・ 2) would also equal 12.
 The number 4 can be read as "shi" in Japanese while the number 8 can be read as "ha". If put together with the Japanese word "i", they spell "shihai", which means rule or control. This reflect this card's ability to manipulate Phantom Tokens.

Number 49: Fortune Tune 
 49 can be read as "fōjūkyū" in Japanese, which sounds very similar to its Japanese name "Fōchun Chūn".
 "Chun chun" in Japanese is also the sound of a bird's chirping, hence it being a bird.
 Given the fact this monster alludes to fortune, it can be implied that 49 is the squared amount to the number 7, which is a lucky number  and it also happens to be a Number monster that is related to luck.
 The first and the 2nd digit of this "Number" matches this monster's ATK and DEF value respectively (400 and 900).
 This card's name and number may be based off of the California gold rush of 1849.

Number 50: Blackship of Corn 
 This cards Number may refer to it being the fifth manga Number card to make a debut, the first four being, "Number 17: Leviathan Dragon", "Number 39: Utopia", "Number 10: Illumiknight" and "Number 20: GigaBrilliant".
 Coincidentally, the word "Kōngō" at the end of this card's Japanese name has the word gō in it. This may reference the 5 in this card's number, as gō is the Japanese word for the number 5.

Number 52: Diamond Crab King 
 Given this card's name and appearance, the 52 can be paired with the measurement of the masses of gemstones, which employs the unit of measure known as the carat. While this monster's number could of been another value, 52 carat diamonds are a wellknown and mainstream marketing measure of diamonds and the average price of such diamonds can be well into the thousands, if not the ten thousands of American dollars, which could also reflect this card's girth and its 3000 DEF.
 Also with its DEF, if you subtract this card's digits (52), you would get 3; this card's DEF is a multiple of 3 and also has a 3 in its value too.
 In Japanese, the number 5 (gō) inpart, translates to the English verbs, "to bore" and "excavate". This can evidently further associate back to this card's name and appearance, as diamonds are usually mined by doing such actions, as they are scarce gemstones.
 52 also happens to be the amount of cards in a Poker deck, and "Diamond" is one of the four suites in Poker. In addition, "King" is a value in Poker, and "Crab" in Japan is pronounced in a similar way as "Club", another of the four Poker suites.

Number 53: HearteartH 
 The numbers 5 and 3 individually can be pronounced as "go" and "mi" respectively, together making the word gomi, which means "trash". This matches this monster's owner, Dr. Faker, who uses a Garbage deck and uses trash as projectiles to harm and wreck apart Astral world.
 The number also reflects its Xyz Materials required, which are 3 Level 5 monsters.
 The sum of this card's number plus "Utopia"s equals 92, which is the numeric value of this card's upgraded form: "HearteartH Dragon".

Number 54: Lion Heart 
 The subtracted result from the numbers 5 and 4 equal 54=1, which matches this monster's Rank.
 Having been used by Nistro and Alito in a tagteam duel, it can be implied that since the series start and up to that point both duelists used a total amount of 5 Rank 4 Xyz Monsters ("Heroic Champions Excalibur", "Gandiva" and "Kusanagi" by Nistro and "Battlin' Boxers Lead Yoke" and "Star Cestus" by Alito).
 When individually read in Japanese, the numbers 5 and 4 become "gōshi" which translates to the following:
 "trade" or "commerce": Being businessrelated vernacular, these lexi in the anime, may vaguely allude to Spartan City, whose outskirts were this "Number"s ruins. Despite its antiquated name, Spartan City prides itself on its Spartancity Tournament, which is perhaps its cradle of business. It also seems to have upscale shopping places there too, as seen when Tori Meadows and Rio Kastle shop there
 "the five fingers": Also in the anime, this "Legendary Number" is based on a gladiator; the term, which translates to "swordsman" in Latin, references the fact that gladiators primarily used their hands in the sport, of which humans have five digits on each hand. This is further supported with Alito, who is not only the gladiator in question but who also partook in the Duel involving this card and who uses the "Battlin' Boxer" series, which takes after the sport of boxing, a sport that solely uses the hands as well.

Number 55: Gogogo Goliath 
 This card's number may refer to the Japanese sound effect gō, which could mean "gō" the Japanese word for the number five.
 If you add this "Number""s separate digits (5 + 5), you get 10. 10 is by chance, the number of "Illumiknight". That being said, the following relations can be made between the two:
 Both this card and "Illumiknight" share the same Rank and ATK.
 Similar to how 10 is the sum you get when you double five, this card's 1200 DEF can also be doubled to 2400, which is also "Illumiknight"'s DEF.
 Both cards also bear resemblance to Effect Monsters associated with these Xyz Monsters (this card's obvious referencing the "Gogogo" archetype and the cavalier seen on "Illumiknight" resembles "Daybreaker", of which three of the said monster were used to first Summon "Illumiknight" in the anime.
 When this card was released in the OCG version of Primal Origin, there were 5 other "Number" monsters and 5 "Number C" monsters included in that Booster Pack.
 Before it was released in OCG version of Primal Origin, there were 5 Gogogo monsters that were already released.

Number 56: Gold Rat 
 The first and the 2nd digit of this "Number" matches this monster's ATK and DEF value respectively (500 and 600).
 Its Number may also be related to the Japanese for 5 and 6, go and roku, respectively, beginning with "g" and "r", as do gold and rat.

Number 57: TriHead Dust Dragon 
 5 and 7 can be read as "kona", which means "powder" or "dust", hence this monster's dust theme.

Number 58: Burner Visor 
 If the 10 in "Number 106" (corresponding to Girag's "Giant Hand") is ignored, the remaining 6 added to this card's numerical value sums to 64. This is by chance, the Number of "Ronin Raccoon Sandayu", the Legendary Number pertaining Girag, who is also the owner of this card.
 Even more coincidental is that both "Sandayu" and this "Number" have the same ATK and DEF.
 If you reverse this card's digits, you would get 85, the number of "Crazy Box". Coincidentally, both cards are shaped like 3dimensional geometric shapes, with "Crazy Box" shaped like a cube, whereas this card is shaped like a sphere.
 When individually read in Japanese, the numbers 5 and 8 become "gōhatsu", which in part translates as "be cold departure" or "be cold hearts." These cryptic translations may refer to the Duelists whose Duel marked this "Number"'s debut (Alito V.S. Girag). In the Duel, Alito did such to break Girag from Don Thousand's influence on him, which has made him coldhearted. In fact, Alito himself was also liberated from Thousand's grasp; while possessed, Alito acted the same way as he did at the time, as seen when he assaults the Different Dimension Airship and enmeshes Tori Meadows in thorny vines before his Duel with Yuma.

Number 61: Volcasaurus 
 This monster is the polar opposite of "Number 19: Freezadon", in terms of attribute, effect, stats, and the Number, which is the upside down read of Freezadon's 19.
 This is also the 1st number to include 6 in its name.
 The subtracted value of each digit equals 61=5, which matches this monster's Rank. It is also the first Rank 5 monster to be introduced.

Number 62: GalaxyEyes Prime Photon Dragon 
 If you add this card's digits (6 + 2), you get 8, this card's rank.
 It may also refer to the Rank of the same value as "Number 107: GalaxyEyes Tachyon Dragon", as that card and "GalaxyEyes Photon Dragon" will both be in the Duel that this card makes its debut in.
 If you flip the Numbers' notation "62" upside down, you get a Numbers' notation 39, a possible nod towards Kite's early rivalry with Yuma.
 The combined values of 62, representing GalaxyEyes Prime Photon Dragon, and 39, representing "Number 39: Utopia", gives off 101, representing "Number 101: Silent Honor ARK". All the monsters mentioned turn out to be the true ace cards of all 3 main protagonists of YuGiOh! ZEXAL: Kite, Yuma, and Reginald.
 The 6 in "62" of this card could represent the appearance order of it, as it is the 6th presented Dragon related to the Legend of the Dragons of Light and Time. (The other 5 that have appeared are, in order: "GalaxyEyes Photon Dragon", "Neo GalaxyEyes Photon Dragon", "Number 107: GalaxyEyes Tachyon Dragon", "Number C107: Neo GalaxyEyes Tachyon Dragon" and "Number 46: Dragluon".)
 On that note, it is also the 6th Rank 8 Dragontype Monster to be released in the OCG.
 Also, this is the 6th "Galaxy" monster that belonged to Kite, while the 2 refers to amount of Mizar's "Galaxy" monsters.
 This card has 3 tails (2x3=6).
 The combined ATK and DEF of this card is 7000, if we take out last two "0"s we have 70, this number minus its rank (8), gives 62.
 If this card's numbers are divided by each other (6/2), the result is 3, being the 3rd Rank 8 "Galaxy" monster.
 Up to the Booster Pack this card was released in, Primal Origin, there are six GalaxyEyes monsters, from which two are based on Tachyon particles.

Number 63: Shamoji Soldier 
 In Japanese, 6 and 3 can be read as "mu" and "mi", forming "mumi" (無味)  "dull", "tasteless", referring to how its holder's food was horrible before the "Number" attended his wish.
 This was the 6th Rank 1 monster introduced, and 3rd Rank 1 Number monster introduced.
 Given this "Number"'s foodie theme, this card's digits can be abstractly interpreted as having similar shapes to food utensils and instruments:
 The 6 can be imagined as either being shaped like a spoon or a pan/skillet, all three with a curved handle (the latter two of which this monster's head is also shaped like.)
 The 3 can also be seen as being shaped like the prongs of a fork, which is commonly used to aid in eating; this is supported by this monster holding what seems to be a pair of chopsticks, a trademark eating utensil in oriental restaurants.

Number 64: Ronin Raccoon Sandayu 
 Akin to "Number 106: Giant Hand," the 6 in this "Number" can also be read as "roku" in Japanese, which could inpart be interpreted as a pun on the word "rock"; this inturn could be referring to this card's Attribute being EARTH and this card belonging to the EARTHAttribute "Raccoon" Archetype.

 The 4 may allude to the sum of this monster's Level requirements for this card's Summontwo Level 2 monsters.
 The subtraction between its digits (64) produces a difference of 2, which matches this monster's Rank.
 The Nintendo character Super Mario wears a Tanooki (Tanuki) Suit in multiple games and is the flagship character of the Nintendo 64.
 If you reverse this "Number"'s digits, you get 46, the number of "Dragluon". Incongruously, in terms of the episodic order of YuGiOh! ZEXAL, the "Number" ruins of "Dragluon"'s is visited first, followed by this card's.
 Furthermore, 64 is a sequentially greater number than 46, which is uniform with the episode(s) count when this card's ruins was visited, being greater than the episode count when "Dragluon"'s was visited in sequence.

Number 65: Djinn Buster 
 By adding up both digits (6+5=11), then adding up all the the digits of the result (1+1=2), the total sum equals 2, which matches this monster's Rank.
 Including the RankUp varieties, this monster and its "Number C" version are each the 5th and the 6th Number monster to show up during the Legendary Numbers War arc.
 If the digits in this card's number are read separately in Japanese, they can be read as "mugo". Adding an additional "i" at the end, you get "mugoi", a Japanese word for cruelty, brutality, and mercilessness. This can refer to the legend of Vector, who was a ruthless prince in his past life that slaughtered his own people and invaded the United Lands of the Poseidon Ocean.
 If you reverse this card's digits, you get 56, the number of "Gold Rat". You can then make the following arguments based on the fact that after this said reversal, the former new digit is one more and the latter digit is one less than they were before:
 Similarly, this card's Rank is one higher than "Gold Rat"'s.
 "Gold Rat"'s ATK is less than its DEF, which could coincide with its former digit (5) being less than its latter digit (6). Conversely, this card's ATK is greater than this card's DEF, which shares continuity with its former digit (6) being greater than its latter digit (5).
 Also with their ATK, if you add "Gold Rat"'s ATK and DEF (500 + 600 = 1100), take the two "1"s given the aforementioned one less and one greater allegory, multiply them by 100 (so it becomes two100s, or 200) and add them to the said sum of "Gold Rat"'s stats (1100 + 200), you get 1300, the same value as this card's ATK.

Number 66: Master Key Beetle 
 The Japanese term for 6 is "roku", which sounds similar to its pronunciation of the English word "lock" (rokku), reflecting its keylike horn and unlocking capabilities (it is, in fact, the starter key for the Dimensional Airship).
 The number 6 itself could arguably resemble the more antiquated, circular metal keychains with a linear article strummed from it.
 This card's number can be the abbreviation of 666, which is the number of the devil. This can be refer to Vector, the diabolical antagonist of the ZEXAL series and owner of this card.
 If you add both 6s in this card's Number, you would get 12. Peculiarly, the next "Number" this card's former owner Vector would Xyz Summon ("Masquerade") requires 3 Level 4 monsters, whose Levels would also add up to 12.

Number 69: Heraldry Crest 
 The shape of the number 69 resembles that of a yinyang graph, reflecting this monster's dual nature: it is a LIGHT monster that is dark colored and is, apparently, sinister in nature. The monster's form itself resembles a yinyang symbol.
 Further augmenting its Attribute connotation is that the Attribute of "Number 96: Dark Mist" (96 would be the number 69 in reverse) is DARK, the opposite Attribute of the LIGHT Attribute.
 Much like "Number 8" reflects Vetrix's relation to Quattro, this Number might reflect his relation to Trey and Quinton, as both digits of this Number match the single Numbers used as aces of each of the two brothers.
 This Number is a reference to Trey's "Number 6", Quinton's "Number 9" and Quattro's "Number 15" (6+9=15).
 This card's number is a sum of "Number"s Kite summoned before Vetrix debuted it (which are 10, 20, 30 and 9).

Number 70: Deadly Sin 
 The 7 in number 70 most likely stands for the seven deadly sins, as implied in its name. Most of Kyoji's "Numbers" are divisible by 7, to reflect this.
 Moreover, the fact that a 0 follows the 7 may represent the opposite of committing such sinsbeing free of sin.

Number 72: Shogi Rook 
 Not counting the Numbers obtained by Kaito until that point, this monster is the 7th Number monster introduced in the manga, and the 2nd to belong to one of Kyoji Yagumo's henchmen.
 Being based on Shogi, which also alludes to chess (which might show playstyle relation between Hishakaku and Kaito), the number might reflect both these games' boards: Shogi is played on a 9x9 zone board, while chess is played on an 8x8 zone board, so the cross between these equals 9 x 8 = 72.
 Still with the Shogi allusions, if you add this card's single digits (7 + 2), you would get 9, the only dimension that makes up Shogi game boards, which as mentioned above are 9 x 9 squares.

Number 73: Abyss Splash 
 The midpoint, or average of the two digits matches its Rank. (7+3)/2 = 5.
 This Number might allude to Shark: its 1st digit matches the 2nd and larger digit of the 1st Number that possessed him ("Number 17: Leviathan Dragon"), while its 2nd digit matches the 1st and larger digit of the Number that became his ace in the anime ("Number 32: Shark Drake").
 The numbers 7 and 3 can be read as na and mi, forming nami, which means wave, matching this monster's title as the Waterfall Deity.
 This card references the number of Xyz Monsters: Shark had 7, while Rio 3 Xyz Monsters in their possession before this card was summoned.
 If you subtract this card's single digits (7  3), you would get 4. Peculiarly, after this card's debut Duel, the next time Shark would use this card was in his Duel with Chironex. For that Duel, Shark pairs up with Quattro, who goes by the codename "IV" in the Japanese anime and whose "Number" cards also strongly reference the said moniker.

Number 74: Master of Blades 
 This monster is the 4th Rank 7 Number monster released.
 The numbers 7 and 4 can be read together as "nanashi" (名無し), which means secret, anonymous, stealthy, which might reflect this monster's appearance as that of an Middle Easternthemed assassin.

Number 77: The Seven Sins 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin".
 This monster is the 77th of the original "Number" monsters revealed.

Number 79: Battlin' Boxer Nova Caesar 
 The number 7 can be read as "shi" and the number 9 can be read as "ku". If read together, they create the word shiku, which is the Japanese word for "match", "equal", or "overtake". This reflects the main user of the "Battlin' Boxer" archetype, Alito, who always likes to keep up and overcome opponents that he enjoys Dueling against.
 7 and 9 can also be read together as "NaKu", which are the first two syllables of "Nakkuru", the Japanese reading of "Knuckle", referencing both the knuckles of a fist as well as "Battlin' Boxer"'s Japanese name, "Burning Knuckler".
 Between this card's separate digits, an 8 can be placed inbetween the said digits to form an ascending, numerical sequence (if read from left to right.) Coincidentally, this card's number in its debut release in Primal Origin is 89, which not only also has an 8 in it, but is also an ascending, numerical sequence if it were read in the same fashion.

Number 80: Rhapsody in Berserk 
 When individually read in Japanese, you get 8 as "ha" and 0 as "o"; concatenating them forms "hao", which means "conqueror" or "supreme king", which is relatable to this monster's Japanese name.
 The 8 may come from the sum of the Levels used in this card's Xyz Summon, which are two Level 4 monsters (4 * 2 = 8)
 If you reverse this card's number, you get 08, which is the number of "Heraldic King GenomHeritage". The following deliberations can then be made:
 Both cards' names are associated with some degree of regality ("Genom Heritage" having the word "King" in its name and this card's said numeric Japanese interpretations.)
 Both monsters require two Level 4 monsters to Xyz Summon. By the same token, they also each have an "8" in their numbers, which might allude to the sum of the Levels of their Xyz Materials.
 Both monsters inpart have effects that directly influence the stats of other monsters (this card can increase an equipped monster's ATK and "Genom Heritage" can pillage an Xyz Monster's effects and name as well as make one's ATK 0 and transfer the said stat to itself.
 Both monsters are used by Number Holders that have some kindred with the Barian World ("Genom Heritage" by Vetrix and this card by Alito.)
 This card's number references the episode when Yuma and Alito had their first battle.

Number 81: Superdreadnought Rail Cannon Superior Dora 
 If the 8 and 1 in 81 are read individually in Japanese, they produce the following words:
 "tsu" and "chi", which when combined creates the word "tsuchi", which means earth (referencing this card's Attribute).
 "tsu" and "tsu", which when combined creates the word "tsutsu", which means gun (which is in the OCG name of this card) or gun barrel.
 "tsu" and "i", which when combined creates the word "tsui", which means pair or couple (a possible reference to the Couples Duel that Yuma and Anna Kaboom participated in during episodes 92 and 93) and also references the pair of trains carrying the rail guns..

Number 82: Heart Monster Heartlandraco 
 If you add 8 + 2 you get 10, and if you don't count 0 as a number (because it's not considered a real quantity) you have "Number 1", which is Mr. Heartland's "Number" in the anime.
 Additionally, given this card's similar nomenclature to "Number 92: HearteartH Dragon", 10 is also the difference between "HearteartH Dragon"'s number and this card's.
 The tongs of the windup key on this monster's belly resembles the number 8, one of this card's digits.
 Literally considering the word "Heart" on this card's name, the 2 may come from the two visible hearts on this monster's body.
 Still about the hearts, 8 in Japan can be read as "ha", while 2 can be read as "tsu", together they spells out "hatsu", which sounds very similar to "haatsu", the Japanese pronunciation of "hearts".

Number 83: Galaxy Queen 
 This Number might refer to March 8th, or 8th day of 3rd month, which marks the International Mother's Day. This reflects this monster's role in the story as a motherly figure.
 Astral obtained this "Number" during episode 8 of the Anime, and it is the 3rd hostile "Number" to be absorbed.
 If you subtract this card's digits (8  3), you would get 5. Coincidentally, beside this card, Nelson (this card's former owner,) uses five other monsters, whose appearances take after characters from his TV show The Sparrow: "BeastWarrior Puma", "D.D. Esper Star Sparrow", "Dimensional Jet Iron", "Ironhammer the Giant" and "Phoenix Beast Gairuda".

Number 84: Pain Gainer 
 Most "Number" monsters Kyoji Yagumo has used are divisible by 7, referring to the Seven Deadly Sins, being the name sake of his main Number monster, "Number 70: Deadly Sin" 7X12=84.
 On particular, this card could referencing the Deadly Sin of Sloth, seeing as it doesn't even have to attack to damage to opponent.
 The number 8 can be read as "chi" while the number 4 can be read as "shi". If put together, they create the word "chishi", which means lethal or fatal. This may refer to this card's effect of inflicting damage to the opponent every time they activate a Spell Card, or possibly a spider bite, which may contain venom.

Number 85: Crazy Box 
 When individually read in Japanese, the numbers 8 and 5 can be read as "hako" (箱), which means "box", reflecting this monster's name and appearance.
 Also with its name, the words "Crazy" and "Box" have several salient nuances that if tersely scrutinized, connect back to both these "Number"'s digits, whether separately or together:
 The word "Crazy" has five letters in it, hence the 5.
 If you add all the letters in both words (Crazy = 5: Box = 3 ∴ 5 + 3), you get eight, hence the 8.
 The word "Box" has three letters in it. However, subtracting both this card's separate "Number's" in the order they come in this card's number (8  5) will also give you a 3 as its difference.
 If you reverse this card's digits, you would get 58, the number of "Burner Visor". Coincidentally, both cards are shaped like 3dimensional geometric shapes, with "Burner Visor" shaped like a sphere, whereas this card is shaped like a cube.

Number 86: Heroic Champion  Rhongomiant 
 At the time of this card's release, there were a total of 14 Heroic monsters released in the game and 8 plus 6 equals 14.
 In Japanese, the number 8 (hatsu) inpart translates to the following, of which the below inferences can be made:
 "first" or "new"This may signify this card being the first "Number" of Duelist Alliance, which is the first booster series of the currently newest OCG booster series (Series 9.)
 "departure"This may correlate to how the Xyz Materials needed for this card's Summon, as well as this card's effects, are arguably, a departure of the norm for the effects of the "Heroic" Xyz Monsters, as this card can use up to five monsters as Xyz Material and as a uniquity in itself, has a multitude of effects depending on the number of Xyz Material attached to it, which is a first for an Xyz Monster.
 When read individually, the 8 and 6 can be read as "Haro", which is one letter off from "Hero", referencing its status as a "Heroic" monster.
 In Duelist Alliance, the booster series of this card's OCG debut, the card designated as number 086 is "No. Hunter". Weirdly, the monster takes after Kite Tenjo in appearance. Moreover, Kite was formerly associated with Nistro, who uses a "Heroic" Deck as his true Deck, which as previously mentioned, this card is a such member of the archetype.
 Further buffering this is that this "Number" card's number in the blister is 087, which immediately follows "No. Hunter" in the OCG.
 When Nistro used his "Heroic" monsters for the first time in his Duel with Nelson, he used 8 Heroic cards, of which 6 were monsters, whereas the other two were Spell/Trap Cards.

Number 87: Queen of the Night 
 By reading the digits of this card's Number separately in Japanese, one can read it as "HaNa", which sounds similar to the Japanese word for "flower", which describes this monster's appearance and the fact it's a Planttype monster.
 The first digit of this Number matches this card's Rank.
 It also matches the Levels of the "Plant Princess" monster series, of which this monster shares many design aspects with.
 If this card's number was divided in half (87 ÷ 2), we would get 43.5. Then, if the decimal value was removed and the remaining digits in 43 swapped places, the number would then be 34; this is by happenstance this card's Set Number in its Number Hunters debut.

Number 88: Gimmick Puppet of Leo 
 Not only does 8 match this "Number"'s Rank, this is also the 8th Rank 8 monster.
 88 is twice as much as the number 44, which, if the numbers are read separately in Japanese, could be read as "shi shi", which means "lion", fittingly describing this monster's name and theme.
 8 is twice as much as 4; this could reflect on its initial owner, Quattro, whose original codename is IV, the Roman number for 4.
 The Zodiac sign "Leo", same as this card's name, covers the biggest part of August, which is the 8th month.
 This monster's pick of number might reflect Quattro's relation to Vetrix, who used to possess the Number 8, just like the Numbers 6 and 9, owned by Trey and Quinton, reflect their relation to their father who possesses the Number 69.
 This card's numerical value is equal the "Numbers" Trey and Quattro used during their duel with Kite and Yuma (15+40+33=88).

Number 91: Thunder Spark Dragon 
 The number "91" is also read as kui, which can be translated as "quick" in Japan. This may reference to Thunder Spark's strategies in Duels which involve quickly swarming the field with monsters in order to summon this card.
 In both the manga and in reallife, this cards' effects allow its controller to either detach 3 Xyz Materials to destroy all your opponent's monsters or detach 5 of such to destroy all your opponent's cards. If both of the said Xyz Material cost values were added (3 + 5) you would get 8. Coincidentally, if you subtract this card's digits (9  1), you would also get 8.

Number 92: HearteartH Dragon 
 The sum of 53, which is the first Number monster used by Dr. Faker, and 39, which is Yuma's first Number monster, equals 92. Coincidentally, the sum of both those monster's Ranks equals this monster's Rank.
 the 9 could match this monster's Rank, while the 2 suggests it's the 2nd Number used by Dr. Faker.
 This is the 2nd Rank 9 monster introduced and also used in the Anime, the first in both aspects being "Number 9: Dyson Sphere".
 By reading the digits of this card's Number separately (9 as "Ku" and 2 as "Tsu"), it can be read as "Kutsu", which sounds similar to "Kuzu", the Japanese word for trash, similar to how Number 53's number could be read as "Gomi" which also means trash.
 The "2" in its number could also refer to the two different ways this card can be summoned: Traditional Xyz Summon or through the effect of "Number 53: HearteartH".
 Coincidentally, this Rank 9 monster was destroyed 2 times in its debut Duel.

Number 94: Crystalzero 
 The subtracted value of each digit equals 94=5, which matches this monster's Rank.
 This Number might allude to Shark and Number 73: Abyss Splash: 9473 = 21. The 2 and 1 matches the lower digits of ("Number 17: Leviathan Dragon") and ("Number 32: Shark Drake"). .
 There is a replete list of applicably separate translations of this cards separate numeric digits in Japanese. If one were to pore over all of these, there are possible reflections of Rio Kastle's (whom this card is meant to embody) past life (as well as her brother to a lesser extent):
 The 9 (kyu) inpart translates as the lexis "ward," "district," or "section." These could be synonyms for the United Lands of the Poseidon Ocean, a kingdom consisting of a series of islands that were ruled by Rio and her brother in their past life.
 The 4 (shi) has a more assorted count of translated terms that could also be relateable:
 "luxury" or "extravagance," which could relate to Rio's then posh living quarters as ruler of the said island kingdom.
 "city"the said island kingdom was a rather dense civilization.
 "death" or "deceased," which could connote to when Don Thousand persuaded Rio to sacrifice herself in order revive this "Number".
 "recollect" or "remember," which could relate to how Rio (who was under Abyss' control while the following action occurred,) showed her brother visions of their past life, hence a recollecting of the past.
 "records," "order," "sequence" and "time"given all the previous points, this card is inpart, associated with Shark and Rio's past lives; this card's debut Duel sequentially became a reflection of these said events, which have led to the revelation that these two characters are Barians (Marin and Nash respectively.)

Number 95: Galaxy Eyes Dark Matter Dragon 
 Dark energy plus dark matter constitute 95.1% of the total content of the universe.
 Dark matter is considered a fraction of the total amount of gravitating matter of nearly 95%.
 Including this "Number", Kaito had 5 Xyz Monsters in the manga when he obtained it.
 Also, he had 9 different Photon monsters before he summoned this "Number".
 Kaito had 5 major battles seen in the manga before he obtained this "Number".
 Also, there were 5 Galaxy monsters that were seen in the ZEXAL manga.
 The number 9 matches this card's Rank.
 Despite its Number not being divisible by 7 and because it was a blank card owned by Kyoji Yagumo; it is possible that this card is a reference to one of the Seven Deadly Sins.
 In this case, because it is used by Kite, it is possible the card is referencing Pride

Number 96: Dark Mist 
 In Japanese, the number 9 can be read as "ku" and 6 as "ro"; together, they read kuro, the Japanese word for "black", referring to this card's OCG name.
 The meaning behind this Number might be the concept of reversal, because 96 will still look the same even if it's flipped upsidedown. So, its effect is based on that concept since it will still have the upper hand when it battles. Likewise, this alludes to the form Number 96 takes when it possesses Astral. In addition to a reverse personality, it had an inverted color scheme.
 The Attribute of "Number 69: Heraldry Crest" (69 would be the number 96 in reverse) is LIGHT, the opposite Attribute of the DARK Attribute.

Number 99: Utopic Dragon 
 This card's number may refer to Yuma's last name, Tsukumo, which can be translated as 99. It is also the last Number that is used against Yuma in the anime.
 Before it was summoned, Astral used 9 "Number"s against Yuma in his final Duel.
 Also, the difference between this card's Rank and the Rank of "Number 39: Utopia Roots" (the "Number" Astral used to RankUp") was also 9.

Number 100: Numeron Dragon 
 The number 100 is often referred to as the perfect number, hence why the "Numeron Dragon" created the world and time.
 Coincidentally, the number 100 can be subliminally read by concatenating the values of its Rank, followed by its ATK and DEF into a textual string (this card is a Rank 1 monster with 0 ATK and 0 DEF ∴ 1 > 0 < 0 = 100 )
 Further, the 1 matches this card's Rank.

Number 101: Silent Honor ARK 
 The 1 in this card's Number may signify the user of this card as being the leader of the Barians.
 This card's number is equal of those of Shark's ace monsters, minus the ace monster Chironex used in a duel against him and Quattro (32+734=101).
 This monster also has two visual interpretations of its numeric value, namely concerning subliminal appearance of the shape of the number 101:
 On the obverse (front) side of this monster, the red glowing marks within this monster's "core", if subliminally "read" vertically as if they were text, can be read as the number 101. This is pretty simple to envision, as it has two red vertical lines sandwiched between three more red designs (hence the two "1"s); while these latter three designs are in a trefoilshape, they sit atop a darkcolored disc (hence the interpretation of the "0".)
 Also with this "Number's" front side, a 101shape can also be envisioned, with this monster's long "wing"s being inbetween its roundshaped "core". This can be made more obvious if one were to imagine this monster's "wings" placed fully erect sidebyside and inbetween the "core" so that they would be perpendicular to the plane of it's core and vertical. The wings would represent both "1"s, whereas the "core" would represent the "0".
 101 can be seen as the combined value of adding together 39 and 62, representing Number 39: Utopia and Number 62: GalaxyEyes Prime Photon Dragon respectively. This seems fitting since all 3 monsters are the true aces of the three main characters in YuGiOh! ZEXAL: Yuma, Kite and Reginald.
 This is Shark's 10th Xyz Monster.
 Also, if the 0 is removed, the final number, which refers to "Number C101" being the 11th Xyz Monster in Shark's possession.
 Yuma and Nasch (aka Reginald) used their aces against Don Thousand in 140th episode, which is the sum of their "Numbers", 101 and 39.

Number 102: Star Seraph Sentry 
 This Number can be seen as an implicit form of the fraction 1/2 (with the '0' taking the place of the backslash). This implicity can refer to parts of this card's effect that halves an opponent's monster's ATK and any Battle Damage you take, moreover, this view is augmented by the fact that this card has two separate "halving" effects, hence two halves.
 Numerically speaking, this is the second OverHundred Number, reflecting its owner's position as the one leading the Barians while Nasch was missing.
 If you add this card's seperate numeric digits (1 + 0 + 2 = 3) and then refer to one of its Japanese translations, the number 3 (san) inpart translates to "sun" in English. This makes sense, as this card is part of the "Star Seraph" ("Holy Lightning" in the original) archetype. As this pertains to a sun, the Sun (and similar celestial masses of akin sizes) are a type of star.
 The sum of this card's digits equals 3, which is the same amount of Dumon's nonXyz "Star Seraph" monsters.

Number 103: Ragnazero 
 If you add this card's numeric digits (1 + 0 + 3), you get 4. The following explications can then be made:
 Marin (this card's owner) is associated with 3 other Xyz Monsters (excluding this card's Number C version), thus making a total of 4: "Ice Beast Zerofyne", "Ice Princess Zereort" and "Number 94: Crystalzero".
 The 4 also matches the value of the latter digit of "Crystalzero".
 This card has 2400 ATK. Oddly, not only is there also a 4 in its value as there is with the said sum of this card's digits but if this number's digits were reversed and subtracted (3  0  1), you would get 2, of which there is also a such number in its ATK.
 The sum also matches this card's Rank.
 The 10' in this card's number are the 10 monsters Rio used and 3 is the amount of Trap Cards, and if the 0 is removed, it is the number of Rio's Spell Cards used, 13.

Number 104: Masquerade 
 By reading the digits of this card's number using Goroawase, one can read the number as "Hi Rei Yo", and arrive at the following interpretation based on this "Number" card's numeric value:
 "Hi" (1, shortened from "Hito") can mean "light" or "daytime" in Japanese, referring to this card being a "Shining" monster, as well as a LIGHT monster.
 "Rei" (0) can be a reference to Rei Shingetsu (Ray Shadows in the dub), who uses the "Shining" archetype.
 "Yo" (4) can mean "night" in Japanese, referring to this card's Number C form, "Number C104: Umbral Horror Masquerade", which is an "Umbral Horror" monster and a DARK monster.
 The 4 in this card's number might allude to its Rank. Likewise, the total sum of all the digits equals 1+0+4=5, which matches its RankedUp form. This can also be viewed as Shining being a rank 4, and the 1 in the "Number" heralds its upgrade by 1 when it becomes Number C.
 The last digit of this "Number" is four, which is the sum of the last digits of "Number 101" and "Number 103", the ace monsters of Nasch and Merag, the two Barian Emperors Vector killed in the past.
 It is also the only ending number amongst the "Number 10X" that matches this card's Rank.

Number 105: Battlin' Boxer Star Cestus 
 The subtracted value of 5 and 1 in this card's number equal to 51=4, matching this monster's Rank. Likewise, the 5 might match this card's Number C version's Rank.
 This "Number" is part of the "Battlin' Boxer" archetype; the said archetype refers to the sport of boxing, which primarily uses the hands. That being said, this card's numeric value as a whole may come from the fact that Human beings, who normally partake in the sport, have 5 fingers per hand. As humans normally have two hands, that's 10 fingers total.
 The 5 in this card's number symbolizes 5 of Alito's battles (against Yuma, Nistro, Dextra, Girag and ZEXAL).
 The sum of this card's digits equals six, which is the same amount of Xyz Monsters Alito had before his Duel with Girag.
 It also signifies the amount of "Numbers" and "Number C" monsters Alito had before being absorbed by Don Thousand.

Number 106: Giant Hand 
 6 can also be read as "roku" in Japanese, which could be interpreted as plays on both the word rock (ロック) and lock, referring to this monster's type and rocky appearance, as well as its effectsealing ability.
 The 6 of this card's value may also allude to the six spheres on this monster: 1 in each finger and 1 in the palm of the hand.
 A feebler connotation to the Number value might be a reference to polydactyly, a condition in which a person has a supernumerary amount of fingers or toes. In most cases, humans have 6 fingers on one or both hands. Normally, humans have 10 fingers, five on each of their two hands.
 A different hand connotation here can be reached with this card's "Number C" form. As "Number C106: Giant Red Hand" also resembles a human hand, both this card and "Giant Red Hand" have a total of 10 fingers.
 Even more similarly to the directly above as well, this "Number" was Xyz Summoned with "Fire Hand" and "Ice Hand", which were also monsters resembling human hands, which both have a sum of 10 fingers too.
 The sum of this card's digits equals 7, which is the equal amount of "Hand" monsters Girag had before being absorbed by Vector.
 In opposite direction, if 6 is deduced by 1, it equals 5, which equals the amount of "Hand" Spell and Trap Cards Girag had before being absorbed by Vector.

Number 107: GalaxyEyes Tachyon Dragon 
 The total sum of all the digits in this card's number equals 1+0+7=8, which matches this monster's Rank.
 It also symbolizes the number of this card's appearances in the anime without its effects known.
 This number is similar to "Number 17: Leviathan Dragon", having a similar numeric value (plus the 0 in the middle), being Dragontype and most notably being the first Number to be introduced in season 2 of the ZEXAL anime, while Leviathan Dragon was the first to be introduced in season 1. Both monsters inpart have an ability that increases their ATK.
 The 7 alone may refer to the fact that this card was the 7th one played in its debut Duel in the episode 82 (after "Goblindbergh", "Zubaba Knight", "Number 39: Utopia", "Overlay Chain", "Radius, the HalfMoon Dragon" and "Parsec, the Interstellar Dragon").
 Before Mizar was absorbed, he used 7 different monsters from his Deck and Extra Deck.
