Alien X is a Celestialsapien able to warp reality itself. It is said that Azmuth removed to voice of reason from Alien X so it can be replaced by the wearer of the omnitrix/ultimatrix. Alien X has 3 personalities or "voices." Alien X is so powerful that he is able to turn his mere thoughts into reality.
Ask politely for the key.
Because you can't.

the only power alien x has is that every thing he thinks comes true but alien x has too much power that when ben turns into him then he is in this other place in the omnitrix with these two heads one with happiness and one with maddness so after the day that happened, ben never wanted to turn into alien x again
Alien X is coloured in black with small, white spots on his body. He has 3 black horns and white hands. I have seen the episode so I know what he looks like. The omnitrix is in the middle. Published by Billsey
Alien X looks like a clear, night sky: just black space filled with stars. His form is that of a musular man with three horns on his head, and the Omnitrix on his chest. No other details can be seen.
this is more of an opinion question, seeing as 1,000,880 aliens haven't even been shown in the series. personally, i think it's ether upgrade or big chill.
