Donnie is a mutated anthropomorphic turtle with brownish green skin. His signature color is purple, most prominently featured in his purple mask. His weapon of choice is a bō (rokushakubo) which also converts to a naginata (a Japanese halberd) via a switchblade inside one end of the staff. Unlike all his previous incarnations, Donnie is much taller and skinnier than his brothers. He also has a gap between his teeth and distinct brown-red eyes. When in combat or when being stealthy, he has whited-out eyes (like the 2003 incarnations).Just like most incarnations, he wears a purple mask where the tails of the mask are longer than any of his brothers, except for Raph's. His ninja gear consists of a strap over his ninja belt, brown knee and elbow pads, light brown bandages wrapped around his ankles, wrists and white bandages wrapped around his fingers. Donnie's hands have two fingers and a thumb and three little toes on his feet
