Hey Paingodsson,

We have a few problems with your characters.

First off, he's really heavy for a person his height and muscle structure. Like, really heavy, I'd go as far as to describe him as being fat. Because he's about fifty pounds more than what I'd expect of a basketball player of his height and build to be. 160, sure, that's fine. 210+? The see you rollin'. Literally.

Second off, I still have no idea what he looks like. I'd recommend reviewing any of Allen's sheets, or one of mine as long as the character is not named Henry. I dont know what his face looks like, there's no distinguishing features about him on his face, there's nothing about facial hair, nothing about his hair style, face shape, etc. Severely lacking.

Thirdly:
"He is an outgoing person, most of the time that is. Except when he knows nobody then he becomes very introverted. But he is naturally extroverted."

He is literally the most confused person personality wise we have. Like, he doesnt even know what he is. His whole personality and appearance are pretty meh, and unfortunately if this character was accepted the way he is (which he's not, because he needs a lot of work) he would be left behind interaction wise. No one wants to interact with a boring character.

You also have two personality sections lol.

Fourth, your history lacks. There's nothing too it besides that 'lol he killed a guy' with no mental drawbacks. You cant just kill someone and walk away from it and be just fine from then on. After selecting a target, the killer often make plans. These plans take a long time to formulate; usually the killer doesn’t want to get caught, so they follow their target around and select the best time and place to strike. 

Afterwards, there is guilt. Remorse. You don’t just kill a person and think nothing of it. I am not a murderer, but I can imagine what it would be like to have killed somebody. They would have nightmares about their victim(s) coming back from the dead to get them. They would be paranoid of getting caught. They would regret ending a life. The dying screams, the pleading, and the look in the eyes of the person they killed would haunt them to their dying day. 

You can’t just walk up to somebody, stab them in the face, and move on. 

You just can’t. 

There is also the point that you dont just 'develop' tourettes. You are born with it, and you have it for the rest of your life.

Fifth, we already have a sound manipulator. Her name is Sylvia and she is bound to make your character useless because she's a bitch like that (and Allen does shit like that because he can. ily Allen <3 ).

Sixth, you cant store sound in your body and then throw it out in a punch unless you're amplifying the sound of your arm cutting through the air to the point where the sound hits harder than the punch.

Seventh and final, your character's mental illness coupled with his power makes him a danger to himself and everyone around him. In the condition the school's in right now they wouldn't accept a person who can accident badly injure or kill another person. Even if it's on accident.
