|First Appearance||X = Ben + 2|
Ben acknowledges Alien X as his most powerful alien; however, he cannot afford the cost that comes with becoming the alien.
As Serena and Bellicus have been arguing for eternity and before they had no tiebreaker, getting them to focus on any present task is difficult at best, leaving Alien X's body trapped in place.
Alien X is a humanoid alien that has white hands. He is all black excluding his hands, which are white. He has tiny white star-like spots all over his body. His eyes are green with no pupils. On his head are 3 horns like Ultimate Way Big.
Unlike most of Ben's aliens, Alien X has five fingers.
Powers and AbilitiesEdit
Alien X is omnipotent, able to warp reality, time, space to any level he wishes.
Alien X's reality warping is so powerful, that his mere thoughts can become real.
Alien X can create an entire universe at will, as seen in So Long, And Thanks For All The Smoothies.
In order for Alien X to perform any action, including simple movement and transforming back, at least two of his personalities must agree to do so. This has proven to be a major weakness, as Serena and Bellicus weren't interested in dealing with present affairs and wanted to finish past ones that weren't possible to deal with without Ben.
In Ben 10,000 Returns, the said weakness was referenced by Paradox, where he revealed that there is an alternate timeline where Albedo transformed into Negative Alien X and was stuck motionless for nearly a year.
- Alien X first appears in X = Ben + 2, where Alien X stops a flood caused by a broken dam. After much fruitless argument, Ben convinces Serena and Bellicus to transform him into another alien (mostly by insulting them). He swears that he won't use Alien X again, as it is not worth the price.
- Alien X returned to Ultimate Alien in The Forge of Creation, Ben half heartedly used Alien X in hopes of locating the Forge of Creation in his last-ditch effort to stop Ultimate Aggregor from obtaining the universe's greatest power. It was revealed that Ben and Kevin hacked the Ultimatrix offscreen and devised a special lock system to prevent bad guys, like Albedo, from transforming to Alien X. With this, using Alien X now requires two keys to be inserted to unlock Alien X. While Alien X is being hidden from the playlist, the keys that which unlocks him are being kept by Gwen and Kevin, who both own one of the keys. After transforming, Bellicus and Serena start debating about other things as usual. Suddenly Paradox appears, telling Ben that he would not be able to convince Bellicus and Serena to help him out today. Also, Paradox puts himself in danger by going into the presence of Bellicus and Serena who almost voted to destroy him, and changes Ben and himself back into his human form before they could come to a vote.
- In The Ultimate Enemy: Part 2, Alien X appeared in the flashback.
- Alien X returns to Omniverse in So Long, And Thanks For All The Smoothies. Alien X successfully recreates the universe.
