Okay, I know this might be a really stupid question to ask, but I have always been on the look out for the being to whole the title "most powerful" and when I was watching this video I got curious as to who would fit the bill in the Marvel universe.
I have looked into characters such as Thanos, Umar, Mephisto, Dormammu, Beyonder, Puma, and Surtur, all of which listed some way that they could be destroyed.
So, my question is two-fold. Who, in the Marvel Multi-verse, A) has the greatest power and B) the smallest (preferably non-existent) weakness?
