Raphael is one of the four main protagonists in Teenage Mutant Ninja Turtles (TMNT). He is the Turtle best known for his sarcastic mouth and hair-trigger temper. Characterized by a red headband, which he wears in all incarnations, he wields two sai in combat.
Originally, in the Mirage/Image Comics, all four turtles wore red bandannas over their eyes, in other versions, Raphael is the only one who retains a red bandana. A straight-up brawler, he is the most violent of the four brothers, he has very little patience for things like stealth, hiding in shadows, or keeping his voice down.
While he’s fiercely loyal to his brothers, he’s also often the one giving them a hard time. Raphael is also the one most likely to strike out on his own when he feels slighted or under-appreciated.
