"Strength" in comic books is hard to qualify, or quantify. One character always has to be stronger than another or there's no stakes. (Which is probably why it's hard to get a solo Hulk movie to work). But power, power is another story.
These are the most powerful beings/entities/characters in all of Marvel Lore. The characters on this list are those that possess the strength, intelligence, and abilities to rival the gods! (There are some gods on this list, and not necessarily at the top.)
We want to know: who YOU think is the most powerful being! Whose more powerful Thanos or the Beyonder? Death or Oblivion? Thor or Hulk? With superheroes hotter than every, evident by so many highly anticipated superhero movies on their way to theaters, debates like these are sure to rage online for the foreseeable future.
Vote up those your think are the most powerful! Vote down those that aren't worthy! Feel free to add any supremely powerful beings we may have missed!
The One Above All is the supreme being of Marvel and master of the nigh omnipotent entity known as the Living Tribunal. He is the only being in the Marvel Multiverse with omnipotence. Unlike his counterpart the Fulcrum, One Above All doesn't involve himself in human affairs.
The Living Tribunal possesses limitless power and is able to erase entire realities from existence. He has no free will, bound to the wishes of his only master: The One Above All. He is nigh-omnipresent and has power that can shade the likes of Oblivion.
The Fulcrum is the ancient cosmic force that the Celestials, the Watchers, and the Horde serve without question. He is almost as powerful as the One Above All himself.
The Fulcrum is also Jack Kirby.
The Beyonder is an immensely powerful extradimensional entity of disputed origin. Virtually omnipotent in his realm, the Beyonder has striven on occasion to be mankind's both greatest savior and enemy in his quests to understand human nature.
