His name is Leo, and the curse has made it to where his armor and mask/helmet cannot be removed, it is stuck to him. He can still speak, and sometimes you can catch a glimpse of his eyes, but he prefers to stay silent nowadays because the curse makes him feel like an outcast anywhere except a fight. The curse can be removed, though, if user finds a way. He can be light and have a fun personality, but he will get frustrated and sometimes sad with the situation he's in, and is very protective.
