"Your short life will soon burn out. With that light, I will suck it all up!"

―Dark Mephisto Zwei

Dark Mephisto (Zwei) (ダークメフィスト(ツヴァイ) Dāku Mefisuto (Tsuvai))[2][3] is a Dark Ultra Warrior that appeared in Ultraman Nexus. He was created as the successor of Dark Mephisto.


  • Giant of Darkness (闇の巨人 Yami no Kyojin)
  • Black Devil (黒い悪魔 Kuroi Akuma)



Like the first Mephisto, he is named after the German devil Mephistopheles. The "Zwei" suffix on his name refers to the digit number "2" in German, since he is the second Mephisto.

Despite his real name being Dark Mephisto (Zwei), he is only refered to as Dark Mephisto in the series, at the end, Zagi only mentions Faust and Mephisto, either not caring or grouping the two together.


Ultraman Nexus

"I was a manipulated human. Just like that Misawa guy. He (Unknown Hand) uses the darkness within the heart."

Shinya Mizorogi.

The exact origin of Dark Mephisto (Zwei) was unknown, but he possessed the Memory Police officer Hiroyuki Misawa during Mizorogi's attempt to escape captivity from the Freedom Fortress. At least according to Mizorogi in his last breath, the Unknown Hand (Dark Zagi) manipulated Misawa into a dark giant by corrupting his heart, exactly as how the original Mephisto did to the former Night Raider sub-captain before.

"You should already...have lost the ability to transform!"

―Dark Mephisto Zwei

Mephisto Zwei defeated Mephisto

Misawa exposed himself to Nagi and Komon by shooting his predecessor and transforms in order to take Mizorogi's place as the bringer of darkness. Even with Ultraman Nexus' intervention, the two giants are evenly matched in speed before Zwei pinned him to absorb his energies. The redeemed Shinya transformed into Dark Mephisto through sheer will and join the fight against his successor. Although it appeared that Zwei has the advantage again, Mephisto turn the tables by holding his duplicate while Nexus Junis Blue fired his Arrow-Ray Schtrom, reducing Zwei to light particles.
