The Fulcrum is the second most powerful person in the Marvel universe next to The One Above All, but that's only if you aren't one of the people who believe that he is actually The One Above All. Both have been depicted as Jack Kirby, and it's also a bit odd that The Fulcrum would be so powerful and just hang around bartending. That's right, he's a bartender in a bar for the Eternals in the afterlife. That sounds like The One Above All just trying to fit in with the homies. You know they wouldn't act cool if they knew The One Above All was around.
He goes by "Jack" or "the bartender," and I'm sure his bar is the kind where everybody knows your name. That's what we need. A superhero version of 'Cheers!'
