Nega Ben is an alternate and evil version of Ben Tennyson.
He wears a black version of Prime Ben's hoodie, grey trousers and black shoes. His eyes are grey with black eyeliner under them. His hair covers one of his eyes and is in a choppy style. His Omnitrix is also colored grey.
He is very negative and gloomy and finds everything lame.
He first appeared in "And Then There Were None", in Los Soledad where he was part of the fight between every Bens as Gutrot. At the end of the episode, just like all the other Bens, he was erased from space-time by the Chronosapien Time Bomb.
In the next episode he was brought back into existence by Good Ben as Clockwork then was sent back to his own dimension.
Powers and Abilities
In fight, just like every other Bens, he relies on his Omnitrix.
