Slim-Worst is a character in Ben 10: Omniverse.
Slim-Worst is somewhat different from other Atrocians, because he is an offshoot one. He has a normal body shape that is colored orange. He has a large, black unibrow and eyes. He has lumps on his arm just like the other males from his kind. He has yellowish, broken teeth coming out of his mouth. Slim-Worst wears a pair of tighty-whitie underwear along with x-shaped tape over his red belly-button.
