Albedo (Ben 10)

Albedo is a recurring villain in the franchise as well as a secondary villain in Alien Force.

He is Azmuth's former assistant, in his attempt to recreate the Omnitrix, turned himself into an imperfect clone of Ben Tennyson, and now Vilgax's right-hand human, despite the fact that he already has Psyphon. Since then, he has been trying to get back to his Galvan form, while also harboring a great hatred and thirst for revenge for Ben Tennyson.

Albedo was a brilliant young Galvan scientist, who served as Azmuth's assistant. In **Trouble Helix**, he inadvertently had a hand in upgrading Malware into his current form when he was captured and forced to connect the new Helix with the old one. In the flashback, he was an ally of Ben Tennyson, and was very loyal to Azmuth as he called him "First Thinker" and even fought for him when Malware approached.

At some point after, Albedo asked Azmuth for an Omnitrix for himself, as he didn't trust "a mere human", though his request was denied, as Azmuth stated that there could be only one Omnitrix. Azmuth later fired him, though Albedo claims he quit. Albedo then used his knowledge of the project to build a copy, and set it to match Ben's. However, when doing so, he didn't know that Ben's DNA would become the default, causing him to permanently lose his Galvan form and become a clone of Ben.

Disgusted by what had happened to him, Albedo traveled to Earth to get the Omnitrix from Ben in **Good Copy, Bad Copy**, planning on using it to restore his original form.

During his search for Ben, in at least three days, he savagely attacked at least three Forever Knight castles and a DNAlien hive, for the purpose of interrogation to discover Ben's whereabouts, causing the Knights to believe Ben Tennyson was attacking them for no reason and attracting Gwen's and Kevin's attention. When Albedo and Ben eventually met during Albedo's siege at another castle, Albedo pretended to be the creator of the Omnitrix, accusing Azmuth of being a liar, and asked Ben to hand it over. When Ben became suspicious and refused, Albedo transformed and attacked him in order to take his Omnitrix by force. After battling him twice, their Omnitrixes locked on with each other, almost causing feedback that could have destroyed the whole galaxy. During the process, Albedo's human form was damaged, resulting in him becoming a negative version of Ben. Azmuth then arrived and took off Albedo's Omnitrix's core, trapping him in his human form and sending him to an alien prison. Blaming Azmuth and Ben for his condition, Albedo swore to get revenge on them.

In **The Final Battle**, Albedo escaped from prison with the help of Vilgax, and stole the Ultimatrix, an incomplete model of the Omnitrix, from Azmuth. Using pieces from his broken Omnitrix, he successfully completed the Ultimatrix and tried to use it in order to transform back to his Galvan form. However, the Ultimatrix was still linked to Ben's Omnitrix, leaving him trapped in his form. Vilgax then offered him an alliance, promising he would let him get Ben's Omnitrix. Though not really trusting him, Albedo accepted and helped him by kidnapping Gwen and Kevin. Despite the alliance being a success, Vilgax quickly double-crossed Albedo and made him his prisoner, using an army of thousands of Humungousaurs against him which defeated Albedo. After the Omnitrix was destroyed, Ben freed Albedo and forced him to hand over the Ultimatrix by triggering the self-destruct command. Though the ship then crashed into one of Earth's oceans, Albedo had escaped.

When Kevin and Gwen put in the Ultimatrix Security keys for Alien X's transformation in **The Forge of Creation**, Ben stated they did it so Albedo wouldn't get access to it if he took the Ultimatrix back or if there was a duplicate or otherwise, something similar in sync to it.

Albedo returned in **Double or Nothing**; ever since Vilgax's ship blew up, Albedo was "broke and stranded" and had created his own live action show, 'Ben 10: Live', where Albedo played the role of Ben, and three of Ben's top most popular aliens, Swampfire, Humungousaur, and Big Chill, are played by three actors with fake Ultimatrix symbols: A Methanosian named Swamps, a Vaxasaurian named Hugh, and a Necrofriggian named Fridge.

After Albedo set a soundwave-bomb on the ground, Ben told Kevin and Gwen to 'deal with the bomb', while he went after Albedo. Albedo supposedly 'turned into' aliens, which were really just the real aliens replacing him before Ben saw the switch. When Ben battled all three of them, he told them that he knew they weren't Albedo. After talking to Albedo, telling him to never again do Ben 10: Live, Albedo stated that he wouldn't.

They were about to leave, but Hugh arrived and lied to the team, saying Albedo was making a doomsday bomb that would make everyone on Earth into a copy of Ben. They went to stop him at an old warehouse and saw Albedo wearing a large Omnitrix symbol on his chest, which Hugh said was going to protect him from the blast. Gwen questioned why Albedo would wear it if he already looked like Ben, but Ben cut her off and used NRG to blow a hole in the wall.

Albedo then yelled at the other aliens to keep them away. NRG defeated Swamps, and Gwen and Kevin defeated Fridge. Then, Hugh tried to defeat NRG, feigning he was on Albedo's side. Ultimate Spidermonkey went after Albedo, only to be reverted by the field surrounding Albedo. In their human forms, Albedo overpowered Ben and tried to worked on the "bomb", only for Ben to interfere again and cause the whole theater to suddenly blow up.

Albedo transformed back into his Galvan form, revealing that the machine wasn't a doomsday bomb, but rather a device to return him to a Galvan as well as making him able to alter his DNA at will. Restored to his Galvan form, he told Ben, who was expecting a fight with Albedo's new powers, there was no point in continuing their feud anymore, planning to get off Earth and never encounter Ben ever again. Unfortunately, he transformed back into Ben and found out, due to the Ultimatrix interrupting the device's alteration field, he would inevitably turn back into his human form.

Hugh tried to take the blame and explained why he sabotaged Albedo's plan, but Albedo didn't blame him and instead furiously blamed Ben. Albedo transformed into Negative Rath, and battled Echo Echo. When Negative Rath pinned Echo Echo down, Echo Echo went Ultimate Echo Echo and send sound wave discs at Negative Rath. This caused Negative Rath to transform back to human and faint. Ben relinquished Albedo to the alein trio, but warned he wouldn't be happy when he woke up.

Albedo returned again in **Night of the Living Nightmare**, where he attempted to infect Ben with a Cassiopeian Dream Eater, trapping him into a dream world where he kept being attacked by several of his enemies. Eventually, when Albedo entered the dream posing as Kevin and Gwen in an attempt to take the Ultimatrix, Ben figured out it was him from his friends stating he didn't deserve to bear the Ultimatrix and pursued him to Mr. Smoothy's.

As Ben started taking over the dream world and overpowered Negative Big Chill and NRG in human form, Albedo attempted to put back the Dream Eater, only to slip on a spilled smoothie and accidentally end up being the one infected. In the real world, it was revealed that Ben was never infected with the nightmare-inducing parasite. Albedo attempted to, but was dangerously unprepared for how messy Ben's room was, which resulted in him dropping the bug on his own face when he inadvertently slipped on a spilled smoothie, thus replaying the same thing that happened in Albedo's nightmare. While they called a Galvan doctor in order to properly remove the Dream Eater, Albedo was seen inside the dream world, being confronted by a group of the Ultimatrix aliens and fearfully begged them to not to hurt him as they came near.

Albedo reappeared in the present day in **The Ultimate Heist**. In it, he had been impersonating Ben for several days, after he and Khyber secretly switched his and Ben's places. Albedo did not use his alien transformations, due to the fact that the red eyes would give him away to Ben's allies. Even though his ruse was discovered and Ben escaped, Albedo managed to get what he needed from Inspector 13. The devices that he took would not only stabilize his transformations, allowing him to remain in them for as long as he wants, but allow him to once again access the Ultimate Forms, including his own, Ultimate Albedo.

In **A Fistful of Brains**, Albedo tricked Ben into entering Khyber's disguised ship, capturing him and taking him to Khyber's private hunting area. Beforehand, Albedo had left toenail clippings and hair on several planets, in order to fool anyone who tried tracking Ben by his DNA.

Ben managed to escape Khyber and confronted Albedo. When Ben pointed out that Albedo had what he wanted, which was the power to return to his true Galvan form, Albedo informed him that he wanted revenge for his humiliation and imprisonment. Ben managed to overcome Ultimate Albedo, only for Ultimate Albedo to declare that Ben hadn't really won. Khyber then revealed that he had captured Azmuth.

In **For a Few Brains More**, Ultimate Albedo intended to use the device he imprisoned Azmuth in, a Cerebral Vortex, to drain Azmuth's intellect, and add it to his brainpower. Despite managing to drain Azmuth's intelligence into an orb form, Ben and company managed to free Azmuth and his intellect; however, after a lengthy battle, which culminated on Earth, Ultimate Albedo managed to escape to Billions Tower, and used its lab to construct another Cerebral Vortex and added Azmuth's intellect to his own, easily subduing them. However, the combined brainpower led to Ultimate Albedo having an epiphany, realizing that destroying them was worthless, as they would still exist somewhere in the omniverse. This distraction allowed Ben to reverse the procedure, taking away Ultimate Albedo's stolen brainpower.

Angered, Ultimate Albedo transformed into Negative Ultimate Humungousaur and began attacking Ben as Bloxx, and pummeling him until he transformed back into normal and Azmuth hit the dial, transforming Ben into a new alien, Atomix, who was easily able to beat Negative Ultimate Humungousaur and Negative Ultimate Spidermonkey. After having his intellect restored, Azmuth punished Albedo by reconfiguring his Ultimatrix to not only keep him as a clone of Ben, but as a clone of the 11-year-old Ben Tennyson. Mortified at this, Albedo cried.

Albedo returned in **And Then There Were None**, in which he and several other evil Bens joined forces with Vilgax and Eon to wipe out every good Ben from the multiverse. However, he, along with the other evil Bens, was double-crossed by Vilgax and were erased from spacetime by a Chronosapien Time Bomb.

In **And Then There Was Ben**, he was brought back into existence by No Watch Ben. Later, he chased an Omnitrixless Ben Tennyson as Negative Ultimate Echo Echo along with Mad Ben and Bad Ben's Buzzshock. At the end of the episode, he was sent back to the Prime Timeline by Clockwork.

In **Malgax Attacks**, Albedo and Vilgax infiltrated the Galvan Historical Museum to steal Malware's remains. While Vilgax fought Ben, Albedo attempted to obtain the secrets of Azmuth only to be stopped by Luhley, Blukic, Driba, and Azmuth himself. He used Ultimate Rath to finish them all off until Azmuth disabled the Ultimatrix. Albedo was then sentenced to clean-up for the next "30 Galvan solar cycles", in which he demanded sunblock.

In the Legacy of Chris Thorndyke,

And he is reprised by Yuri Lowenthal, who voiced Ben Tennyson just with a more evil tone in his voice in the English dub and he will be voiced by Tomokazu Sugita in the Japanese dub.
