Mizar, also known as Mizael in the Japanese version, is a Barian Emperor in Yu-Gi-Oh! Zexal II and one of the Seven Barian Emperors. His primary goal is to gather the Numbers cards in order to save the Barian World from destruction. He is characterized by a fearless and fierce demeanor, coupled with a cunning instinct and keen intellect that make him a formidable opponent. Mizar carries a superior attitude that often alienates his fellow Barians, yet his dueling skill is unquestioned. He sees himself as the true master of the Galaxy-Eyes archetype and views Kite Tenjo as his primary rival, challenging him to determine who is the superior Galaxy-Eyes user. Unlike some other Barian Emperors who become distracted on Earth, Mizar is straightforward and serious, focusing immediately on his mission, though he does enjoy showcasing his power in a flashy manner. As a dragon tamer, Mizar wields the powerful Galaxy-Eyes Tachyon Dragon, and he is also able to use Barian Battlemorph transformations. His backstory reveals that he was once a human who protected his land alongside a dragon named Jinlong; he eventually sacrificed himself to defend his people, leading to his reincarnation as a Barian. This past instills in him a deep sense of loyalty. Throughout the series, Mizar is a major antagonist, operating under the command of Dumon. He is defeated in a duel, and his soul is absorbed by Don Thousand, but he is later revived by the power of the Numeron Code after the final conflict between Yuma Tsukumo and Astral. His development is marked by this cyclical fall and redemption, though his core pride and dedication to his cause remain constant. His key relationships include his rivalry with Kite, his respect for Dumon, and his interactions with other Emperors such as Girag and Alito, whose antics he chastises. In terms of abilities, beyond his dueling skill, Mizar possesses enhanced physical capabilities as a Barian, including the ability to survive in the astral plane and use his Tachyon Dragon’s time-manipulating effects.
