Nega Ben

Nega Ben is an alternate and evil version of Ben Tennyson.

Appearance
He wears a black version of Prime Ben's hoodie, pale green 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.

Personality
He is very negative and gloomy and finds everything lame.

History
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 spacetime by the Chronosapien Time Bomb.

In And Then There Was Ben, he was brought back into existence by No Watch Ben. Later, he tried to attack a freshly timed out Ben 23 but was binded by Gwen 10's Wildvine. At the end of the episode, he was sent back to his own timeline by Clockwork.

Powers and Abilities
In combat, just like every other Ben, he relies on his Omnitrix.

Etymology
Nega is defined as "denoting the negative counterpart of a unit of measurement, in particular a unit of energy saved as a result of conservation measures." It has become a common word used to describe an evil version of a character from another universe, such as the villain Nega Duck from the Darkwing Duck animated series.
