History

Ultraman Nexus

A year before the series started, he was Deputy Captain of the Night Raider and he was very close to Nagi, he and Nagi had the instinct to know the existence of Space Beasts even when the TLT equipment could not. After that, Mizorogi dreamed that he encountered a strange ruin,

One night, he and Nagi went to a building and they defeated the Beast Human. Their corpses were covered with beast cells. After they defeated the Human Beast, Mizorogi went alone and he was met by Dark Mephisto, Mephisto explained to Shinya that humans defeated Space Beasts while Space Beasts ate humans, therefore Mephisto finally merged with Mizorogi after he explained his social darwinist ideology.

Dark Mephisto is the mastermind of all events, he ordered Nosferu to kill Riko's family and he was the one who killed Riko by firing Cannon Blast in Riko's face. After Faust died, Mizorogi psychologically tortured Komon and in the end he challenged Himeya/Nexus to a fight. While in the middle of the battle, Mephisto summoned Nosferu to capture the little girl as a hostage in order to psychologically torture Komon again. Mizorogi again summoned Himeya to challenge him when Nosferu returned, after which the two of them fought in Mephisto's Dark Field, both of them were badly injured and they surrendered. Mizorogi hasn't given up and makes another plan to make Komon side with Mizorogi by creating a vision of his dead girlfriend, but Mizorogi's plan is thwarted by Himeya. Mizorogi still hasn't given up, when he is surrounded by Komon, Nagi, Jun and other Night Raider, Mizorogi makes Dark Field in human form and summoned Galberos, while Nexus is fighting Galberos, Mizorogi taunts Ultraman and he is shot by Nagi from behind but not dead.

After his repeated defeats, Mizorogi intends to open the Gates of Darkness to kill Ultraman and all of the Night Raiders. He summoned Kutuura to defeat Ultraman. After Ultraman died in the Land of Death, the Night Raider arrived and defeated Kuutura. Mephisto transforms into Mephisto and challenges Night Raider to fight him. In the middle of his battle with Night Raider, Ultraman awakens but is still weak. Illustrator then tells Night Raider to fire the Ultimate Vanisher into Nexus' Energy Core. Nexus awakens and starts fighting once again. After a fierce battle between the two giants, they collided with the strength of their beams. Mephisto then disappeared.

Mizorogi was still alive and survived his fight with Himeya but he lost his memory. During the Banpira incident, Mizorogi was arrested by TLT. While he was detained, Director Matsunaga revealed to Mizorogi that he had hurt people and committed heinous acts. Then, Unknown Hand returned his memory and Mizorogi managed to escape. when Misawa revealed himself, he cowardly shots Mizorogi in the back and nearly kills him before transforming into Misawa/Zwei.

While Nexus's power was being absorbed when he fought Dark Mephisto Zwei, Mizorogi himself while still injured, ultimately decided to help Nexus, and he was able to transform into Dark Mephisto again because Mephisto power was still in him, while Mephisto's original personality had already disappeared from him. Dark Mephisto then ambushed and fought Dark Mephisto Zwei through sheer will and joined the fight against his even more violent evil successor, while managing to land many kicks and hits against his opponent, that is until Dark Mephisto Zwei himself unexpectedly and completely overpowered and severely stabbed Dark Mephisto in the chest. Dark Mephisto then sacrifices himself so that Dark Mephisto Zwei can be defeated. Although it appeared that Dark Mephisto Zwei himself had the advantage again, the injured original Dark Mephisto suddenly turned the tables on Dark Mephisto Zwei by literally grabbing and forcibly holding his evil twin duplicate while Nexus Junis Blue fired his Arrow-Ray Schtrom, reducing the vile Dark Mephisto Zwei into light particles, ending the evil Dark Ultra's life for good.

After the brutal fight, Dark Mephisto reverted to his human form and was cradled in the hands of Nagi, but before to his fatal injuries he asked Nagi for forgiveness while also warning Nagi by informing her that Unknown Hand (his true former master and creator) was in the Night Raiders and he and the other Dark Ultras are all just a puppet that Unknown Hand used for his own nefarious purposes.

Trivia

• It is unknown which of Zagi's giants was created first but certain evidence and dialogue implies that Mephisto was created first.
• Mephisto is the first male evil Ultra Warrior to have a shown transformation item, and is also the first to have said device being sold as a toy.
• It is deliberately ambiguous how much of the actual giant Mephisto was left after his defeat at Himeya's hands. Mizorogi's much more subdued and peaceful nature after his return implied the giant was dead. However, his powers, voice, and mannerisms all return after Mizorogi regains his memories, implying Mephisto also chose to redeem himself.
• Mephisto is the second Ultra Warrior to be redeemed from darkness, the first being Ultraman Tiga. However, his redemption is on-screen.
• In the original planning, a different voice actor was chosen for Dark Mephisto before Takeshi Yagi decided to employ Mitsutoshi into the role instead.
• Dark Mephisto's lacks a Color Timer noise in the series, hence for his appearance in Ultraman Nexus video game, he received a blinking noise that was recycled from Ultraman Neos.
