A problem child with a vengeance
The Cocoon is deadly silent, due to his muteness, so everyone in the city thinks he's just another loner. However, he is very intelligent, and very narcissistic. He wants to destroy every Olympus child, excluding himself, because he feels that they are all unworthy to have such a gift. He loves to torment people, and he of course kills for fun.
The Cocoon has the ability to make a copy of himself, that's sort of like a dummy. He can control it, however it does not have any of the other powers The Cocoon has. It can fight, but The Cocoon mainly uses it to intimidate. He also protects himself with a cocoon like layer of skin, which will prevent him from getting hurt by any projectiles, and reduces damage from anything direct. However, it does break eventually, and will leave him vulnerable. Lastly, The Cocoon has super strength abilities, but he only has them when he has his cocoon.
The Cocoon had a name once, but he doesn't remember it at all. His family had been living on the streets a year before The Cocoon was taken away. They were going to sell him to the black market due to his muteness (they themselves thought he he was mentally retarded). Law Corp came and took The Cocoon away, noting his largeness, and his seeming ability to not be hurt as much as other children. They did tests on him, which eventually made him go blind in one of his eyes. It did give him a cocoon, thus making Law Corp name him The Cocoon. When Mythos came, The Cocoon declined the offer, and was dumped into New Belfast. Since then he has lived on the streets, trying to find other Olympus children. He wants to kill them all.
