You fools, don't you see it's time for a new list - one that makes sense
1. Batgod w/ utility Belt (Adam West version -possibly spite)
2. The Presence
3. The Spectre
4. Lucifer & Michael
5. Teen Titans Robin
6. Mr. Mxyz
7. Ion & Parallax
8. Lois-is-dead-bloodlusted-Superman
9. Antimonitor
10. fanboy Kirby Darkseid (grr that was an avatar)
on a more serious note - I'd include Doc Manhattan (yea I know he's technically Vertigo) somewhere on the list based on his sheer potential. Edit: I suppose you could say the same about full potential Cap Atom too.
