Alien X as his Alien Force/Ultimate Alien appearance, but he has longer horns, and he is more muscular. His stars now occasionally sparkle and are larger. His colors match the color palette of Heroes United.
Ben slams down the Infinimatrix's dial and is engulfed in a green light.
As the transformation track begins playing, Ben hovers in a dark green background with light green bubbles pulsating rapidly behind him. Ben spreads his arms out as his eyes change shape slightly, turning completely green. The camera zooms into his eyes as black and white energy (like a starry sky) sweeps through his internal body, making his organs vanish. The energy reaches his hands, and covers his external body. Ben crouches as the camera rotates around him. His hair disappears and three horns emerge from his head. His muscle mass increases slightly and the Infinimatrix symbol pops out of his chest. Alien X stands completely straight, completing the transformation.
Alien X has three personalities: Serena, the "voice of love and compassion", Bellicus, the "voice of rage and aggression", and Ben, the "voice of reason". All three of these voices combine to form Alien X's speech. Otherwise, Alien X is silent. The only things he will say are what he will be doing - what Ben, Bellicus, and Serena have agreed to do.
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. This leaves Alien X's body trapped in place, floating about a foot above the ground until an agreement is made.
Powers and Abilities
Alien X is omnipotent, being able to warp reality, time, and space with ease and at any level he wishes. Even his thoughts can become real. In short, Alien X can do anything.
Alien X can create time waves to reverse events.
Alien X can create and recreate an entire universe at will.
Alien X can self-duplicate, create galaxies to suck in other beings, and travel at high speeds. He also possesses superhuman strength and the ability to grow to a gigantic size. He is skilled at hand-to-hand combat.
Alien X possesses telekinesis and is capable of deflecting energy attacks, such as those generated by a Prypiatosian-B.
In order for Alien X to perform any action, including simple movement and transforming back, two out of three of his personalities must agree to do so. This has proven to be a major weakness, as Serena and Bellicus were not interested in dealing with present affairs and wanted to finish past ones that were not possible to deal with without Ben.
Alien X is vulnerable to having his powers absorbed.
Alien X's actions onto reality can be neutralized and reversed by the intervention of other Celestialsapiens.
- Alien X was one of the 10 aliens in Ben's new roster after the Omnitrix recalibrated in Ben 10 Returns: Part 1. He was locked upon the Omnitrix's reset at the end of War of the Worlds: Part 2.
- In Up to 11, Azmuth reunlocked Alien X.
- Alien X veers much closer to his portrayal in Alien Force and Ultimate Alien, whereby:
- Two out of three of his personalities need to agree in order to perform an action instead of all three.
- In addition, he can generally overcome any obstacle as long as an agreement is reached between his personalities, which in itself is difficult.
- His voice is that of all three of his personalities combined.
