Alien X is a humanoid alien with a black body with white hands. White outlines most of his body. He has a tiny white stars on his body that makes him look like space. He has 3 horns on his head and the Omnitrix is on his chest.

Powers and Abilities

  • Alien X is omnipotent being able to warp reality and time/space itself.
  • His reality warping is so powerful that his thoughts can become reality such as being able to create an entire universe at will.


Alien X has 3 personalties Bellicus the voice of rage and aggresion, Serena the voice of love and compassion and Ben the voice of reason. In order for Alien X to perform any action at least 2 out of 3 personalities have to agree. Since Bellicus and Serena have been arguing for eons it is hard to get them to agree on anything making Alien X practically useless. However beginning in Universe v. Tennyson, Ben has become better at getting control of Alien X from Bellicus and Serena. 

Other Celestialsapiens are capable of harming Alien X

He cannot survive on Anur Vladias.
