Raphael, is the brute out of his 4 brothers.

His red mask resembles a du-rag, having a bit of holes in it.

He's rough with everybody else but since you're much smaller, and he want to hurt you on accident, he's a bit more gentle.

He's mean and aggressive, sometimes being a little sweet, but it's in a little mean way, like he'll give you something but grunt and walk away, rolling his eyes after you thank him.

He's overprotective of you, and can get jealous easily.
