メタトロン

A white angel who combats the Black Lodge and is seen as a hero by most of Arkham City. Metatron tries to dissuade Kurou from confronting the Black Lodge and does not believe herself to be the hero of justice that Arkham's population views her as. She possesses a suit of white, angelic armour that protects her from damage and allows her to fly. The armour is also equipped with a voice scrambler that hides her true identity. Metatron can also manifest wrist-mounted blades and beam cannons on her forearms, and is also a proficient hand-to-hand fighter. Her true identity is Leica. As befits a henshin heroine, she also has a signature attack, the Slash Cross. Later in the story she acquires the Hunting Horror, a flying motorcycle created by Doctor West that incorporates pages of the Pnakotic Manuscripts, giving it some of the characteristics of a Deus Machina. The Hunting Horror can only be driven effectively by an individual that has been artificially enhanced, such as Metatron or Sandalphon. "Metatron" is the name of an angel prevalent in medieval Jewish mystical texts and other occult sources. [From Wikipedia.] During the events of Kishin Hishou, Leica regained memories from her previous route and awakened again as Metatron.
