Don Thousand

Don Thousand is the god of the Barian World and the central antagonist of the Yu-Gi-Oh! ZEXAL anime. It was later revealed that he was from Astral World.

Appearance
Don Thousand has a rather demonic appearance, with luminous red eyes, dark red skin, black wings and what 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 version of the Emperor's Key.

Personality
Don Thousand has shown himself to be a very direct individual, always going directly to the point and doesn't usually stray from the subject at hand. He is also perceptive during his brief conversation with Vector, knowing full well of his hatred towards Astral (though he was unaware of Yuma) and his hand in Merag and Nasch's disappearance. He is not above threatening Vector, though he has not shown any sort of sadism in doing, and it appears to be more out of caution and concern for his own agenda. He can be enigmatic at times and is not above withholding information when asked until a later time. Later, it was also shown that he has a malevolent side to him, taking over Vector without any regard for his host's safety in the slightest. This is a trait that he allegedly always possessed and it was this malevolence that gave birth to Number 96: Dark Mist.

Etymology
Don is a name given to three different lakes, and also translates to "gift" or "sir" in Spanish. So, accordingly, "Don Thousand" might mean "Thousand Lakes", "Thousand Gifts" or "Sir Thousand".

Abilities
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, the stylized version of the Barian Emblem appears on the subject of his powers. He is also capable of harming his host as he demonstrated by grabbing Vector's heart when he argued with Number 96: Dark Mist. He also has knowledge of Earth, insinuating that he knows where the locations of where the Legendary Numbers are, but he did not reveal those locations, much to Vector's annoyance. His powers can heal other Barians, but those who fall under his influence in the process, develop a darker and more malicious disposition. 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. He is also the only known being capable of creating millions of copies of "Number" cards (fake "Number" cards to be exact).

History
Don Thousand battled Astral thousands of years ago and lost, being sealed in the Sea of Ill Intent. According to Jinlong, this battle brought destruction to the world and so it must never be allowed to happen again. During this battle, the Barian deity embedded in Astral a shard of his malice, eventually becoming Number 96: Dark Mist.

Yu-Gi-Oh! ZEXAL II
After being defeated by Yuma and Astral several times, Vector journeyed to the Sea of Ill Intent. 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 "Legendary Numbers", which would fully revive Don Thousand. Vector agreed and Thousand merged with him, empowering Vector with new abilities and restoring his broken form. Using Thousand's powers, Vector accelerated the healing of Girag and Alito.

As Vector made his way to one of the ruins, Don Thousand told 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 Dark Mist. When Dark Mist and Vector argued with each other, Thousand squeezed the latter's heart to stop him. After Number 96 and Vector parted ways he told the latter to let him go and informed him that Alito and Girag should be awake then.

Thousand later informed Vector that the last two "Legendary 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 Nasch and Merag. He then ordered Vector to find Number 96 as the latter was about to put his own plan into effect. 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.

Thousand proceeded to lead Vector to his palace, to which Number 96 had returned to in a ball of light after its defeat. Upon revealing its origins, Thousand instructs Vector to obtain the sealed Number, to whom wished to go crush Yuma with it immediately. Instead, Thousand left his body in energy form and insisted that now was not the time yet.

He revealed a device that would combine the Barian World and Earth together. If the malice of the human world reached that of the Barian World, they could be fused, amplifying his power one-thousand fold - enough to destroy the 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.

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 Fake Numbers are complete. Thousand told Vector that it is time to begin his machination.

During the world merging when the Barian Emperors had gathered in the Barian World with Rio and Reginald having become Nasch and Merag, Vector worried if Nasch would remember what he did to them before but Don Thousand assured Vector to not panic as Nasch was not "thirsting for blood". While it is not clear if Nasch or Merag remember that Vector murdered them, when Dumon questioned Vector if he knew anything about the world merging Vector feigned ignorance and decided 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.

Collected Numbers
Unlike regular Numbers, Don Thousand creates an entirely different series of "Fake Numbers", four of which he gave to Vector, who in turn gave one to each member of the Fearsome Four of the Dark Dueling World. The rest were passed on to various humans on Earth via his Dimension-Fusing Device. According to him, there are a million Fake Numbers of his creation.
