@Falbium_Asmodeus: Yes! you really get me, man. The Choushin and TLT are perfectly Nigh-Omnis. Barring pre-retcon Beyonder and Molecule Man of course.
Yeah, if I were to correctly describe Alien X it would be this: "He's Just Too Goddamn Broken For His Verse!".
And like you stated, Tenchi and Z are capable of defeating him, yet they are considered to be nowhere near Nigh-Omnipotence.
Lol at this dude trying to debate against creator statements.
If you don't want alien x to be omnipotent then make your own ben 10 fanfiction LOL
