Albedo (BTR)

Albedo is a major villain in Ben 10: Revamped, who is not a Galvan with a copy Omnitrix, but an evil clone of Ben created by Vilgax from the Unitrix for the purpose of stealing the real Omnitrix.

As he is simply the Unitrix (albeit modified), he can be deactivated just like canon Eunice, as Vilgax has shown.

Duplicate Omnitrix
Albedo was cloned from Copycat fur. This fur had Ben's DNA infused with Omnitrix energy, and turned into Copycat, the Unitrix produced an evil Copycat with a fully functional Omnitrix that would revert back to a Ben clone with an Omnitrix. This Omnitrix cannot be removed, as it is permanently bonded to him and the Unitrix.

Biography
He was cloned in Plan B by Vilgax from Copycat fur, and used to capture Ben and bring him to the Chimerian Hammer miles above Bellwood. While Vilgax was stealing the Omnitrix, he turned on Albedo, who fought back, and whose errant zaps caused system malfunctions that released Ben and activated the ship's self destruct mode. Vilgax won the fight and deactivated Albedo, but not before Ben could escape out of a hatch with the Omnitrix. The Unitrix/Albedo's fate in the explosion is unknown, as not even the crash of the wreckage was shown before the end-of-season cliffhanger.
