Albedo is a Galvan with an Omnitrix that impersonated Benjamin Tennyson in the Ben 10: Alien Force episode, "Good Copy, Bad Copy". His real form is a Galvan, but was stuck as a clone of Ben. He used to be Azmuth's assistant. Albedo uses the forms of: Humongousaur, Jetray, Goop, Spidermonkey, Echo Echo, and Big Chill. Towards the end of the episode, he was stuck in the form of Ben, but with silver hair, red irises, and a red jacket. Later, Azmuth comes and removes the Omnitrix's Core (though not the band as it is near impossible to remove) from him and states that only one Omnitrix is allowed on this world. Albedo gets locked up and prison and vows to have revenge on Ben when he gets out. He craves chili dogs in Ben's form and attacks the Forever Knight's castle as Jetray, and the knights call it "The Curse of Ben 10".
