Card Trivia:Number 40: Gimmick Puppet of Strings


 * This card's Number comes from its owner, IV, whose name is the Roman Numeral for 4.
 * Furthermore, this is the fourth Number monster owned by the Tron Family and the fourth Number to belong in an existing archetype.
 * This card also shows a style of sorts for IV's currently known "Numbers". "Gimmick Puppet Giant Killer" and "Heaven's String" have numbering puns which are based off of IV's own name, being "15" and "40." This could be a representation of how IV tries to finish goals his own way and how he disagrees and argues with the other members of the Tron Family.
 * This is the second "Gimmick Puppet" "Number". The first is "Number 15: Gimmick Puppet Giant Killer".
 * "Heaven's Strings" is likely the offensive counterpart to "Giant Killer". Its ATK and DEF is the inverse of those of "Giant Killer" plus 500.
 * Also it can destroy monsters after battle then inflict damage during the opponents turn, while "Giant Killer" can activates its effect to inflict damage before battle during the owner's turn.


 * This card's second effect is similar to "Speed Spell - The End of Storm" and "Winged Kuriboh LV10".


 * As with most other Xyz Monsters with them, when this monster absorbs an Overlay Unit, it absorbs it through its sword.


 * When this card activates its effect it plays the strings on its chest with its sword like a harp, Then red glowing puppet strings come down from a portal and attach to every monster on the field.


 * This is the first "Number" monster where the "Number" printed during its Summoning in the anime and the Number on its body are not the same color. When it is printed during its Summon, the Number is a plum color, but on the monster itself, the Number is red. This might be an animation error.


 * This is the second "Number" monster that requires a specific Attribute for its Xyz Summon. The first is "Number 96: Dark Mist", though in both case this only applies to the anime.


 * Heaven's Strings, like "Giant Killer" and "Machu Mach", are the first Numbers seen to not be obtained either by Astral or Kite even after their owners have been properly defeated in a Duel.


 * This is one of four Number monsters whose Number appears twice in its artwork.
 * The first Number Monster to have a larger version of its Number in the background is "Number 15: Gimmick Puppet Giant Killer".
 * The second Number Monster to have a larger version of its Number in the background is "Number 6: OOPArts Atlanthal".
 * The third Number Monster to have two "07" numbers, one on his staff and second is on the dice he held is "Number 7: Lucky Stripe"


 * This card is the first Xyz Monster to use counters: String Counters.


 * This card's effect shown in the anime is very similar of the "requiem for strings" technique from Benetnasch Eta Mime from the Saint Seiya Asgard arc.
 * Both play a harp and strings attach to the opponent strangling them during the music.
