You can use characters from any comic, novel, cartoon (including anime), movie, TV show, etc... by omnipotent I mean multiversal omnipotent beings who have absolutely no limits, can't be defeated, etc (in other words 99,9% of fictional characters are allowed)
@ThatGuyWithHeadPhones: Well, Goku was faster than lightening when he was like, 10.. There was an entire episode in DB titled "faster than lightening" I can only imagine enel trying to touch goku from start of DBZ... And about any saiyan owns enel in destructive capabilities. (Even roshi and 1st saga piccolo took out moon :o)
Beyonder, he isn't omnipotent
Yes, he was.
then how could doom steal his powers?
Have you actually read the Secret Wars II?
no i didn't, i don't read much of marvel, but im sure that doom stole beyonder's powers.
@PrinceAragorn1: Considering that writers will make him stronger to suit whatever hes up against id think so, hes never going to be allowed to loose.
"writers will make him"
not the future.. the current. There are so many characters like that. Goku, for example doesn't have any upper limit. But he isn't any closer to strongest than superman.
