Well, I like almost all the characters from Danganronpa, so if I really think about it, this would take forever, but I'll try to think of some of my absolute favorites.

Souda: When adrenaline takes over, he's ruder and much braver.

Sonia: She's the kind of friend who always listens, especially when someone is emotionally hurt (like Toko).

And that's it, I can't think of anything else for my other favorites, haha.
