Abilities
Corpsen has the power of death, he can never die as long as his mask remains on his face. He will continue to age but as long as his mask is on no matter how crippled he is he will still live, this is sad in no way as it means he can have a normal life then die, or if there is something he needs to accomplish he may be able to achieve it within that time period before his body is inable to move.
