Plan B/Info

Summary
The public is getting suspicious about the team after the attack of the previous episode. Vilgax returns, in a ship miles above Bellwood, unleashing his Plan B on the team: Albedo. With Ben kidnapped and Vilgax about to steal the Omnitrix for himself and unlock Master Control, only a fight between Vilgax and Albedo could let Ben escape with the Omnitrix. But something bad is waiting for him on the ground: Will Harangue and his news crew, broadcasting Ben's use of the Omnitrix to everyone watching. Insert cliffhanger here.

Major events

 * Albedo makes his debut in the form of the Unitrix with Ben's DNA, modified to produce an evil clone, and is subsequently defeated by Vilgax by deactivating the Unitrix. His fate after the explosion is unknown.
