First Appearance Alien Force


In Omniverse, Alien X retains his original appearance, but his chin is now bigger like Diamondhead. He is more muscular. The Omnitrix symbol is on his chest still.

Powers and Abilities

  • Alien X has shown to be nigh-omnipotent, able to warp reality and time/space itself, becoming nearly invincible.
  • Alien X's reality warping is so powerful, that his mere thoughts can become real.
  • Because Alien X is Ben's most powerful alien or Ben thinks, as Dwayne states that Alien X is not the most powerful alien in the Codon Stream, but does carry the most risk.
  • Alien X also has enough inhuman strength to smash through entire planets, speed that allows him to move across solar systems in seconds, and the ability to fly through air and space.


Alien X doesn't have any WEAKNESSES since Ben gained FULL CONTROL. (Proof[1])


Ben 10: Omniverse / Alien Force

  • Alien X First appearance was in Ben 10: Alien Force
  • Alien X returned to Omniverse in So Long, and Thanks for All the Smoothies?, Ben finally uses Alien X successfully to defuse the annihiallorg and saves the universe, which is almost destroyed because of it.
