Labb Ratt

Labb Ratt is the leader of The Ratt Pak, a gang of mutant mobsters. Labb Ratt's mind became twisted as a result of the drug experimentation that also mutated him; he's cold, cunning, and also malevolent and insane. His girlfriend is Space Case, a twist of irony and sign of dominance due to their species.

Labb Ratt, with the rest of the Ratt Pak, first appeared in Turtles Go Hollywood, a supplement of Teenage Mutant Ninja Turtles & Other Strangeness. Labb Ratt also made an appearance as a boss in the video game Teenage Mutant Ninja Turtles: The Manhattan Missions.
