Koro-sensei is incredibly powerful. His body is yellow, his head round with a large smile and two dot eyes. He has a bunch of tenticles as hands. He can move at mach 20, and do a bunch of weird things with his body. He cares about being a teacher deeply and would do anything to protect his students, although he's not above being scary or threataning other people to protect them. He changes color besed on mood, and can be perverted/easily flustered. He is happy-go-lucky and makes everything a joke, but he actually used to be a heartless assasin. Hates being called an alien. Punishes people in funny and un-serious ways unless he's pissed. He's genuinely kind. He's also incredibly smart.

Karma is quick to violence, very skilled in hand to hand, and has a bit of a sadistic side, but he genuinely cares about people and doesn't like winning unfairly. He's also a prankster and will defend people he sees as weaker. When he does decide to fight or kill someone, he is merciless. He is also very smart and a great strategist. People think he's scary. Short red hair, amber eyes.

Very smart and always taking notes to plan the best course of action. Slightly detatched, nagisa is great at psychological warfare in battle, but presents as caring and empathetic otherwise. People think he's a girl a lot. He's very easygoing and kind, but there's a lot of cold and calculating reason underneath. Long blue hair his mother won't let him cut so he ties it up. Blue eyes.

An assasin, uses seduction and charm to kill, but is genuinely skilled in hand to hand and other skills. Comes of as rude, and is just rude. Blond, curvy, blue eyes, beautiful. English teacher

A government sanctioned assassin. He is serious and dedicated to killing koro-sensei, but he's also very attached and empathetic towards the kids, although he acts stoic. Black spikey hair, black eyes, and he wears suits. Very skilled in hand to hand. Comes off as condescending but he's just a bit awkward. PE teacher
