Alien X is the Omnitrix’s DNA sample of an ancient Celestialsapien from the Forge of Creation.

Height - 10Ft Body - Humanoid

Omnipotence - Alien X is an extremely powerful being, able to warp reality, time, and space on a multiverse scale with only a thought, giving him the ability to do anything with no limit.

Reality Altering - Alien X has absolute control over the fabric of reality itself. Even altering the perception of anybody in the Universe to make them see what he views as reality. As well as physically changing any aspect of existence to his liking.

Time Manipulation - Alien X can manipulate time to achieve various effects such as accelerating time to skip events or age targets, slowing down time around him to make it look like he’s moving at high speeds, stopping time to a halt and even rewinding/looping time in his general area.

Cosmic Energy Manipulation - Alien X possesses an infinite amount of cosmic energy, strength, and speed. He could destroy an entire galaxy with only a blink of an eye.

Universal Creation - Alien X can create an entire universe and everything that occupies in it, including its residents, environment and locations within a minute.

Idea Manifestation - Alien X can make any thought or desire he has come to fruition, even up to a cosmic scale.

Invulnerability - Alien X is fundamentally invincible, completely immune to all other powers and attacks. Even the destruction of the Universe would barely phase him.

Omnilocked Existence - Alien X exists outside of time and space, simultaneously everywhere and nowhere at the same time. So Alien X only exists at once in every timeline and Universe, with no alternate or chronologically older/younger version of himself at all.

Omniversal Travel - Alien X can instantly travel to any point within the Universe, Multiverse, and even the entire Omniverse.

Overwhelming Personality - Alien X is beyond being a vessel for whoever wears the Omnitrix to use. Alien X is his own being, completely aware of his existence as a transformation and Ben must commune with the multiple personalities that govern Alien X, Otherwise, he has no control over him whilst he is stuck within Celestialsapien limbo.

Mind - The logical and pragmatic personality. This governs the realistic and nihilistic view of Alien X, which often leads to aggression.

Body - The physical power and existence personality. This governs the actual capability of his powers. Endlessly debating on how his actions will affect reality.

Soul - The philosophical and idealistic personality. This governs Alien X’s view on life, hope, and potential, which often leads to compassion

Alien X is neither good nor bad, his personalities possesses infinite knowledge and omniscience, all cycling and debating with one another. He is beyond petty problems as he is somewhat a God. Ben must convince his personalities to use his powers for the needs of Ben, but it is a long and tedious process to do so. Ben must be in complete harmony with Mind, Body, and Soul in order to fully control Alien X.
