What's this about Prime being unbeatable? There are tons of characters in both Marvel and DC who can hand his ass to him, without reality warping.
The problem with reality warping, IMO, is that is thins the relevant opponent stream for the competition. I see what you're trying to say in that being super powerful effectively makes you just as broken as reality warpers, but the principle is different. Prime can be beaten by a broad range of "bigger guns" -- here are some examples of prior contestants who are NOT reality warpers:
- Galactus
- Tyrant
- Dark Phoenix
- Unicron
- Darkseid
- SoK (arguable)
- Darsh (arguable)
- Gogeta (arguable)
Whereas someone like Sarda requires a very specific "bigger gun" -- another reality warper with better feats. At the end of the day, a good energy manipulator/telepath could take Prime out by reading his mind and hitting him with red star radiation (people have made this argument with Surfer). Or you just find someone who is more powerful to blow him out.
TBH, I don't think it matters with Prime, anyways. You guys seem to forget that Mxy couldn't do squat to him, and Mxy is at least as impressive, if not much more so, than the reality warpers in this contest....
