Funko’s latest addition to their TMNT Pop! series features Metalhead, the evil robotic turtle created by Krang to destroy the turtles once and for all. He was imbued with the thoughts and memories of the turtles, resulting in a pretty kick-arse villain. Although fortunately Donatello is eventually able to reprogram Metalhead for good, and he lives his life as the housecleaner of the turtles.
