User blog comment:Whitekey/My ranking of the most powerful Marvel beings (A personal list)--Version 1/@comment-126760-20110613220739

Interesting list. What is your feeling about beings that at their normal power level wouldn't make this list, but at one point, for a limited time, had enough power to make the list? The main example I'm thinking of is Thanos. He once not only fought, but defeated the Living Tribunal while in possession of the Heart of the Universe. Normally though, he is very powerful but probably not in the top 20, but for a short time he would have ranked #2.

You are right to put One Above All in the #1 position, but I sure wish that the folks at Marvel never created him. Once you create a God figure to have absolute power over the Multiverse you take away some of the threat that the lesser super beings pose to it. Living Tribunal is nearly omnipotent but is just vulnerable enough that theoretically he could be defeated.
