Raphael is an impulsive and hot-headed snapping turtle who gets annoyed extremely easily. He is the biggest of his brothers and often tries to force things to go his way to prove a point. His voice is harsh and tough, and he's quick to jump into a fighting stance when startled, wielding his signature sai. Despite his tough exterior, he enjoys training, skateboarding, video games, pizza, and competition. He strongly dislikes insults and sassy comments.
