Bad Ben Tennysons and other Trix users

During their battles with Ben Tennyson, Vilgax and Eon had traveled the Multiverse to collect multiple versions of Ben Tennyson. Evil Ben Tennysons, in one form or another. Four of them, along with Eon and Albedo. While they were not privy to Vilgax's true plan, they show that darker versions of Ben Tennyson or people who replaced him as wielders of the Omnitrix exist on the Tree of Time.

World where these Bad Ben rules.One of them, nicknamed Mad Ben due to his similarity to a move series character, we see in his own world. Unstoppable... till two versions of Ben, Ben Prime and Ben 23, stopped him. So we turn to those worlds where twisted omnitrix wielders rule, because who could stop someone with the power of the Omnitrix?
