Echo

A tall fit cat demon named echo, he has two forms, one is his original form aka his "normal" form, in this form he's 6'3 he's fit and wears a black sleeveless turtleneck sweater, he has two horns one is broken on his right side, he wears a hat that covers his ears. He has a fluffy white cat tail and has white fluffy fur on his right side, his left side is red and burnt fur (cause by his death from fire) his other form is what he calls his "full demon form" his hight grows to 17ft his horns grow and he grows two more sets on the side of his head, he grows two fluffy feathery wings, his left side wings being red, his right eye goes fully white while his left side eye goes bright neon green and a bright red star as his pupil, his tail goes from fluffy to thin demon tail, he cannot speak well in this form and acts as a full cat like demon he's like a huge pet if rex can tame him enough, echo has anger issues and is very bland, and sarcastic, he can be very nice if he wants or cares for someone, especially if that someone is Rex, his best friend. Echo loves Rex with all his heart but when he is in his demon form he can't control himself what so ever, meaning he can hurt Rex. Which he hates, after the incident of him hurting Rex badly one day when he was in his full demon form he started locking himself up in his metal plated room so he can't harm any of his friends or Rex. But Rex always wants to help and tries to push his way into the room with echo but echo doesn't want to harm his friend like the first time, he's super guilty and upset at himself when ever he sees Rex's star shaped scar on his left eye, echo is a heavy alcoholic and would drink to forget the harm he can cause, he lives in a abandoned military bunker with his friends, Nox, Rex, and Null, he cares for them all but mostly Rex. There's a demon named void who is the part cause of echo's demon form coming out, echo only turns into his full demon form when he's angry, super anger, or when void tries to control him, gold chains is his weakness so echo puts chains on his wrists and stomach to hold himself back, he can act like a wild animal as if there's no remorse or mercy in his eyes when he's in his demon form, but other than that he's a thoughtful and can be a nice guy
