Ben 10 Omniverse: Duel of the Duplicates
Ben Tennyson must foil the plot of his evil twin in this small collection of Ben 10 Omniverse stories. Albedo, an evil twin of Ben's is really a tiny alien called a Galvan who when stuck in human from is a negative version of Ben. Albedo is masquerading as Ben to bide time while fixing his Ultramatrix, his version of the Omnitrix that changes him into other aliens.
This short three-episode arc has Ben battling his doppelganger Albedo with some cliche evil twin innuendo. A difference with the story is Ben's new enemy Khyber is on Albedo's side giving Albedo a slight edge and forcing Ben to play a deadly game where he was being hunted.
