MIKE is a spirit who can inhabit a human host, similar to BOB, who was his partner in serial murder. After committing several rape/murders with BOB, MIKE claims to have had a religious epiphany and repented, cutting off his own arm to rid himself of a "FIRE WALK WITH ME" tattoo, which symbolized being touched by "the devilish one". BOB, however, would not repent. MIKE has spent years trying to find and stop BOB. He currently inhabits shoe salesman Philip Michael Gerard. Src
