He is just like Ueydgxbdbdb and Ueydgxbdbdb is a ball with gray color, U and eyes on it (Ueyd/Uey) but he has pale gray as his color, has fully black eyes which one has red dod and is bleeding and second is red glowing. He is evil version of Ueydgxbdbdb and he hates and is hated by Ueydgxbdbdb. TEO is just a short cut of his name since his full name is The Evil One. He is powerfull than god himself and everything that you can think of. He has a little anger issues.
