History
Mister Sinister was presumably a member of Doctor Strange's Church of the Splitting Atom when they stole the Nano Bomb. Goblin Queen and Cyclops disguised themselves as members of the Church, including Mister Sinister.[1]
Notes
- Earth-20007 is the reality in which the stories produced by Marvel Comics of Earth-616 take place on. As such, heroes whose identities are no public may not be those of their mainstream counterpart. In Mister Sinister 's case, his civilian identity is never revealed.
