A mutant abomination that was the result of direct exposure to the Forced Evolutionary Virus (FEV) in the PC game Fallout. Serpentine in appearance, its lashing tongue attack can deliver a lethal dose of poison. The exact origin of this species is unknown, but they were most likely the result of experimentation done by Richard Grey (AKA The Master, the antagonist of the story) with the FEV.
