Magmalot is the freakish version of Firebit found unused in the game's files. Via old storyboards it is revealed that Magmalot (previously named Nightmare Firebit by the community) is the failed experiment of Firebit attempting to clone himself. When it failed, Firebit convinced Magmalot that he was his brother and teams up with him to destroy colonies as The Dark One ordered.
