Fusing our two worlds together allowed me to activate the field spell Numeron Network giving me mastery of the Numeron Code.

— Don Thousand declaring he now controls the Numeron Code with "Numeron Network"

Don Thousand (ドン・サウザンド, Don Sauzando) is the god of Barian World and the central antagonist of the Yu-Gi-Oh! ZEXAL anime due to his undertaking to destroy Astral World because of his banishment for hosting the power of Chaos. He is also the progenitor of the Seven Barian Emperors, corrupting their memories so they could become Barians, to serve as his instruments for his agenda to subjugate the universe.



Lineart of Don Thousand's true and demonic forms.

Don Thousand close-up

Don Thousand's full appearance.

Don Thousand has a similar appearance to Mr. Heartland's Barian form; a demonic form with luminous inflamed eyes, shady red skin and dim wings that appears to be a black carapace. He also has a large, luminous red eye at the center of his abdomen. He has a stylized version of the Barian Emblem on his chest. The spike of the carapace on his forehead form a structure that appears to be a black type of the Emperor's Key. His wings are also covered with red diamonds, similar to Vector and the Chaos-empowered Number 96. He is also the largest of the Barians, being the size of a giant.

Don Thousand's Energy Form

Don Thousand's true form.

Don Thousand's true form is that of a former denizen from Astral World; with luminous gold hair with two long red bangs in front. His appearance is similar to Eliphas. His skin tone is black with red outlined onyx colored armor with his emblem embedded at the center. His heterochromic eyes are blue and red, with the addition of a third eye placed vertically on his forehead. He also wears a set of earrings on his pointed ears. Like Vector and Eliphas, he also has an energy form resembling his true form, with both his body and hair color-swapped and vice versa.


Don Thousand's personality is complicated and dynamic, as he lacks the usual insanity or pride associated with Yu-Gi-Oh! antagonists. He is characteristically malevolent and vengeful, dedicated to spreading Chaos, destroying Astral World and ensuring the universe is his new dominion no matter the cost. He is shown to be a very direct individual, always going straight to the point and does not usually stray from the subject at hand. He is also highly perceptive during his brief conversation with Vector, aware of his loathing towards Astral (though he was unaware of Yuma) and his culpability in Marin and Nash's disappearance.

He has a commanding presence, and is not above threatening Vector, though he does not show any degree of sadism in doing so, and it appears to be more out of concern for his own agenda. He can be cryptic at times and is not above withholding information when questioned until a later time. Upon his return to his chrysalis energy form, Thousand's disposition becomes haughty and confident, casually passing his first turn in his Duel against Mizar. This is due to his confidence in his absolute power due to obtaining supremacy through stealing the power of the Numeron Code by fusing the Human World and Barian World.


Don can translate to either the honorific "sir" or "talent" in Spanish. Accordingly, "Don Thousand" might mean "Sir Thousand" (reflecting his high status) or "Thousand Talents" (reflecting his power and abilities). His name is also an imperfect palindrome in Katakana.


Don Thousand lifting Alito and Girag with ease.

As the deity of the Barian World, Don Thousand possesses great power, even in his weakened state. He can possess Barians, grant them new abilities, and even restore them should they be injured, as seen when he did all of these things with Vector. When this happens, his Emblem appears. He is also capable of injuring his host as he demonstrated by grabbing Vector's heart when he argued with Number 96. He also has knowledge of Earth, insinuating that he knows where the locations of where the Mythyrian "Numbers" are, but he did not reveal those locations, much to Vector's annoyance.

Don Thousand's reaper form.

His powers can awaken other Barians, but those who fall under his influence in the process, develop a darker and more malicious disposition, until they are reduced to mere puppets of his power. According to Don Thousand, both he and Vector are one in body and soul, this prevents the two from truly separating from each other and Vector cannot move far without Don Thousand, though there was one case where he can leave Vector's body temporarily, as seen when he appeared before Alito and Girag. He is also the only known being capable of creating fake "Number" cards. He also possesses great physical strength, as he was able to lift both Alito and Girag without struggling. Each person who has been influenced by him contains a portion of his malice, meaning he can be in multiple locations at once, similar to the Horcruxes of the Harry Potter franchise.

Don Thousand's shaman form.

Even when he was sealed he was capable of appearing in either a ghostly reaper-like form (such as when he appeared to Alito's, Girag's, Vector's, Dumon's and Marin's past lives) or in a shaman form (such as when he appeared to Mizar's past life) on Earth, and in these forms he was capable of brainwashing humans as he did to Alito's friend, the prince, his advisers and Girag's comrades as well as Mizar's neighbors and allegedly used this form to cause the tragic deaths of all the Seven Emperors and embed their souls with the "Over-Hundred Numbers". Don Thousand can absorb people into him through the item on his body, as seen when he did so to Vector. He can also fire pulse waves, which can knock the person down. By having Barian World fuse with Earth, Don Thousand became able to draw upon the power of the Numeron Code itself, despite not knowing its location. With it, he is capable of destroying Astral World.[1]



Don Thousand clashes against Astral.

Don Thousand once resided in Astral World, but was exiled when the realm decided to abandon the power of Chaos.[2] In an attempt to claim the Numeron Code, Don Thousand battled Astral on a volatile Earth, who ended the battle when Astral performing a Shining Draw, which seemingly destroyed much of Astral World in the process.[3] This resulted in fragments of Astral's power being scattered across the Human World to mark the location of the Code. They manifested in the form of the first fifty "Numbers", among them the seven Mythyrian "Numbers"[4] and the four "Numeron Gate" monsters.[5]

During this battle, the Barian deity embedded in Astral a shard of his essence, which eventually became Number 96.[6] Don Thousand's soul became sealed beneath the sea of Barian World,[7] the dimension that formed when Chaos was cast out.[8] Seven Mythyrian "Numbers" attached themselves to legends on Earth and sealed Thousand's power.[4] Although sealed away, a weakened Thousand machinated history against each of these legendary heroes and sages, corrupting their original memories with his Over-Hundred Numbers into becoming the Seven Barian Emperors upon death.[2][9]

Don Thousand became known as an agent of a nation, and in the form of a shaman, he entered a neighboring nation state that was defended by Mizar and the dragon he had tamed. When great disaster struck (which Don Thousand was responsible for), he convinced the populace that the dragon was responsible. They proceeded to torment the dragon, with Mizar offering his own life in the hopes of convincing them the dragon was not responsible. The army of the Shaman's nation state attacked at that moment, killing both Mizar and the dragon with a hail of arrows. Without them, the army easily conquered Mizar's nation.[10] He eventually revealed himself as Don Thousand in disguise.[11]


Mythyrian Numbers War

Don Thousand being revived by Vector.

After being defeated by Yuma Tsukumo and Astral several times, Vector journeyed to the Great Barian Sea. Swimming through it, he found the place where Don Thousand was sealed and released him. He offered Don Thousand his life in exchange for the power to defeat Yuma and Astral. Thousand told him to journey to Earth and find the seven sealed Mythyrian "Number", which would fully revive Don Thousand. Vector agreed and Thousand merged with him, empowering Vector with new abilities and restoring his injured body. Using Thousand's powers, Vector accelerated the healing of Girag and Alito.[7]

Thousand telling Vector to make good of his alliance.

As Vector made his way to one of the ruins, Don Thousand told Vector that the ruins are in his memories, insinuating that he had been to the ruins before, but refused to tell Vector more than that. He was amused at Vector's deja vu and laughed at his confusion, though he denied Vector the answer to his confusion and ordered him to make use of his alliance with Number 96. When Number 96 and Vector argued with each other, Thousand squeezed the latter's heart to stop him.[12] After Number 96 and Vector parted ways, he told the latter to let him go and informed him that Alito and Girag should be revived by now.[13]

Don Thousand speaking to Vector about Nash and Marin.

Thousand later informed Vector that the last two "Mythyrian Numbers" had fallen into the hands of Yuma's allies. He claimed it wouldn't be a problem though. Vector asked how much Thousand really knows and Thousand responded "everything", including what Vector felt when he entered the ruins. He confirmed that Vector was once human, then became a Barian and claimed that he was also responsible for the deaths of Nash and Marin. He then ordered Vector to find Number 96, as the latter was about to put his own plan into effect.[14] They observed Yuma and Astral's Duel with the rebellious "Number" from afar, not being seen by anyone during the Duel and the following events.[6]

Don Thousand explains his plans for Earth to Vector.

Thousand proceeded to lead Vector to his palace, to which Number 96 had returned to in a ball of light after its defeat. As a fragment of Thousand's power, Number 96's "Number" cards were passed to Vector. Vector wished to use his new power to crush Yuma and Astral, but Thousand insisted it was not yet time.[6]

Don Thousand's four collected "Number" cards.

He revealed a device that would combine Barian World and the Earth together. If the hatred of the Human World reached that of Barian World, they could be fused, amplifying his power one-thousand fold - enough to destroy Astral World. To do so, he needed to make more of those devices, which was where the power he regained from Number 96 would go. He revealed four fake "Numbers", each possessing great power to Vector and instructed him to sit on the throne. When Vector did, Thousand fused Vector to it, rendering him immobile as the two needed to stay in the palace in order to put the power to work by building more devices.[6]

Don Thousand laughing after finally completing his device.

Despite losing three of the "Number" cards he and Vector gave to the Fearsome Four of the Dark Dueling World, Thousand was not concerned, as the rest of the fake "Numbers" were complete. Thousand told Vector that it is time to begin his machination to seize Earth.[3]

As the worlds began to merge, the Barian Emperors gathered in the Barian World with Rio and Reginald having become Nash and Marin, Vector worried if Nash would remember what he did to them before but Don Thousand assured Vector to not panic, as Nash was not "thirsting for blood". Dumon questioned Vector if he knew anything about the world merging, and Vector feigned ignorance, deciding instead to pass the blame onto Mr. Heartland. However, Vector told them that it would be the perfect opportunity and that they should invade the Human World.[15]

Barian Emperor Onslaught

Don Thousand physically speaking to Alito and Girag.

During the Duel between Nash and Quattro, Don Thousand and Vector watched as he gauged Nash's power and was surprised when Nash performed a Chaos Draw and gifted that ability to the other Emperors.[16] Thousand later manifested himself outside of Vector's body in order to brainwash Alito and Girag into assisting him and Vector.[17] The portion of his soul that remained in Alito was able to manifest itself and speak to Yuma and Astral when Alito confronted them. He explained he had been exiled from Astral World, but claimed it was a good thing, as Chaos was too restricted within its confines. He told Yuma to blame Astral if he had to blame anyone, and revealed that the acquisition of the seven Mythyrian "Numbers" from the ruins had restored the majority of his power.

He also explained that he had reincarnated seven humans as the Seven Barian Emperors as they were connected to the Mythyrian "Numbers". He urged Yuma and Astral to attempt to stop him if they could.[2] Thousand's influence was later exorcised from Alito's body after a battle between Alito's "Number C105: Battlin' Boxer Comet Cestus" and Yuma's "Lion Heart" - the latter card being the Mythrian "Number" that Alito had owned in his past life.[9]

Don Thousand speaking to Marin and Dumon.

Don Thousand being restricted.

Later on, Thousand confined Nash in an inflamed Sphere Field, restraining him with dark tentacles. He opened a screen before Nash to allow him to witness his sister and Dumon Dueling Vector and Thousand himself, whose power resided in Vector's body. Thousand revealed that he had created the Seven Barian Emperors for his own agenda. When the Duel started, Vector activated the Spell Card, "Don Thousand's Throne" which was given to him by Thousand that drew power from Nash, causing him great pain whenever "Don Thousand's Throne" increased Vector's Life Points.[18] At one point in the Duel, Don Thousand stopped Vector before he made his next move, narrowly saving Vector from defeat in the process.[19] After the Duel, Don Thousand once again appeared to Vector and told him about Girag's memories being restored. This prompted Vector to absorb Girag, with Alito's and Ponta's souls also being absorbed in the process (Alito had previously lost a Duel to Girag).[20]

In order to create a venue for Nash and Vector's struggle, Vector transported the ruins of their previous confrontation to Barian World, and prevented Don Thousand from influencing the battle by restraining him.[21][22] After Vector's true memories were revealed, Thousand was summoned and began explaining his part in changing Vector's past memories, causing Vector to attempt to lose the Duel. When that was revealed to be a ruse to lower Nash's guard, Vector confronted Thousand and revealed his suspicions about the Barian deity's former actions, which greatly upset him. Declaring himself to be more powerful than him, Vector proceeded to burn Don Thousand to ash.[23]

Don Thousand emerges alive and whole.

Upon Vector's defeat, Thousand returned, having been separated from him after the Duel. He called Vector a fool and then proceeded to absorb him, despite Yuma's efforts to rescue Vector. After this, Thousand began to transform, merging with the newly created "Numeron Network" composed of the Human World and Barian World in the form of an enormous purple lotus. Mizar then showed up and Dueled Don Thousand, who emerged in his energy form. However, Mizar (seemingly) defeated himself using "Dragon King's Demise" without Don Thousand having to play a single card and was absorbed. With this, Don Thousand made his final transformation into his true form.[1]

After defeating Mizar, Thousand revealed his true plan: Since he did not know where the Numeron Code was, except that it was on Earth, he fused Barian World and the Human World together to control the Numeron Code. Thousand challenged Yuma and Nash to a Duel, with the Numeron Code allowing Thousand to open a portal to Astral World and directly attack it when Yuma and Nash took damage. During the Duel, it was revealed that Thousand had used the "Numeron Network" as a Field Spell Card to "manipulate" Mizar's cards in the previous Duel, and demonstrated this power again by effortlessly countering the Summon of "Number 39: Utopia" and replacing it with "Ganbara Knight.[1]

Don Thousand dissolves, transferring his powers and "Numbers" to Nash.

Eventually, after "Numeron Network" was destroyed by the efforts of Astral and Eliphas, Thousand Summoned his ultimate ace monster, "Number iC1000: Numeronius Numeronia". However, despite putting Yuma and Nash into a corner, he was ultimately defeated by the combined might of "Number 100: Numeron Dragon", "Utopia" and "Number 73: Abyss Splash", united by "Utopia Rising". Shortly before his destruction, Thousand tells Yuma that Reginald (as Nash) will never reunited with his old friends again as he transferred his "Numbers" and remaining power to Nash before laughing and fading away.[4][24] His dark essence was destroyed when Nash lost his duel with Yuma.[25]

Number Hunting

Thousand manufactured fake versions of the first four "Numbers", which he had Vector distribute to the Fearsome Four of the Dark Dueling World. These were "Number 1: Infection Buzz King"[26], "Number 2: Ninja Shadow Mosquito"[27], "Number 3: Cicada King"[6] and "Number 4: Stealth Kragen".[28]

Thousand owns the true versions of each of these "Numbers", coming in the forms of the "Numeron Gate" monsters - "Number 1: Numeron Gate Ekam", "Number 2: Numeron Gate Dve", "Number 3: Numeron Gate Trini" and "Number 4: Numeron Gate Catvari". These were the first "Numbers" to fall to Earth during his engagement against Astral[5] and were among those that designated the location of the Numeron Code.[4] He was also able to upgrade "Ekam" into "Number C1: Numeron Chaos Gate Sunya".[5] His ultimate monster is "Number C1000: Numeronius", which had no shown base form, and he is capable of upgrading it into the "Imaginary Number" known as "Number iC1000: Numeronius Numeronia".[4]

After Vector's defeat, Thousand absorbed him, resulting in him obtaining the multitude of "Numbers" that Vector owned. Among them were "Number 5: Doom Chimera Dragon", "Number 43: Manipulator of Souls", "Number 58: Burner Visor", "Number 64: Ronin Raccoon Sandayu", "Number 65: Djinn Buster", "Number 80: Rhapsody in Berserk", "Number 96: Dark Mist", "Number 102: Star Seraph Sentry", "Number 103: Ragnazero", "Number 104: Masquerade", "Number 105: Battlin' Boxer Star Cestus" and "Number 106: Giant Hand". His victory over Mizar likewise earned him the "Numbers" that Mizar had collected, among them "Number 6: Chronomaly Atlandis", "Number 9: Dyson Sphere", "Number 33: Chronomaly Machu Mech", "Number 46: Dragluon", "Number 62: Galaxy-Eyes Prime Photon Dragon" and "Number 107: Galaxy-Eyes Tachyon Dragon".[1] With those "Numbers" also came the "Number C" forms of many of them, including those of the "Over-Hundred Numbers".[1]

Upon his defeat by Yuma and Nash, all of his "Numbers" were absorbed by Nash.[24]

Other appearances


Don Thousand uses a "Numeron" Deck[1] focusing on his Field Spell, "Numeron Network" to "rewrite" the moves his opponents tries to do by keeping his field empty at all times when it is not his turn. As stated by Don Thousand it has granted him mastery over the Numeron Code allowing him to rewrite the present, past, and future by fusing Barian World, and Earth together.

For offensive purposes he can summon the "Numeron Gate" "Numbers" which were the first "Numbers" to fall to Earth during his battle against the Original Number,[5] to utilize a quick win by doubling their ATK with the use of "Numeron Network" relieving the use of needing Overlay Units to use their effects. If the attacks fail he can use "Number C1: Numeron Chaos Gate Sunya" to banish all monsters on the field, and inflict damage equal to the total ATK they have allowing him to use a OTK. They key to this strategy is having "Numeron Network" on the field as without it his "Numeron Gate" monsters are nothing more then 1000 ATK monsters, and "Sunya" destroys itself.

If that strategy fails he can use the spell card, "Numeron Chaos Ritual" in order to summon "Number C1000: Numeronius", a monster that is physical manifestation of "Numeron Network" itself to control the field, stop "C" monsters from doing a thing, take control of those monsters, and sacrificing them to ensure it survives on top with having 10000 ATK which is a difficult monster to defeat.

If that tactic fails he can summon it's upgraded form, "Number iC1000: Numeronius Numeronia", a monster that is a Rank 13 monster with 100000 ATK with the added effect of while not being allowed to attack it forces the opponent to attack it unless they grant Don Thousand an Automatic Win. If the opponents to make an attack to prevent that the effect of "Numeronius Numeronia" allows it to negate an attack while Don Thousand regains LP from that's opponent's ATK.

The Deck also symbolizes Don Thousand's views, and goals to obtain the Numeron Code to control all of existence and Time itself, and take the form as the most powerful God ever known.
