Anti-Marine is an antagonist in Fandemonium. She is originally believe to be an alternate reality version of the Sonic character Marine the Raccoon, but she is later revealed to be a robot. Anti-Marine appears first in Fandemonium #22, pretending to be the original Marine and living on an alternate univere island with her unseen son. She takes on a more villainous role in the following episode, in which she nearly kills Steel and hires Clyde to badly wound Flame. She later appears as part of the Almost Killer Conspiracy, keeping Super Hound and the real Marine captive at the Almost Killer's base. Her last appearance in Fandemonium occurs in episode 36, when she is killed by Hiro.
