Who could have defeated "World War Hulk" here?

scarlet witch in the strange movie being a good example. she's probably many tiers weaker than the strongest in the universe but when she started obliterating characters like mr fantastic or professor x with the snap of her fingers or her mind, it became really silly. how does marvel balance out the strongest champs? are their powers contained when they fight each other so their stories can go on?

Powers just change to match whatever story they want to tell. Versions of characters change often too, with their power set changing. Hulk for example has been at many different power levels over the years. Anywhere from not even bullet proof to practically invincible. A genius or an idiot, etc.

This is awesome. My goodness.

And we ended up with pussyboy ruffallo professor hulk.

One of my favorite scenes in Collateral is when he gets abruptly popped in the head by Tom Cruise right as he had finally found Jamie Foxx and was trying to help rescue him.

"Sun got real low there, huh little guy?"

do we need to watch any of the phase 5 stuff to be ready for the doom movie? i missed a ton of shows from phase 4 too.

Even if there's a call back that youre unaware of, they usually tend to emphasize those moments, even the briefest of single frame shots, in some manner or other.

Thor's subtle panic when Cap budges the hammer barely even a slight bit, and then in endgame when he finally picks it up, thor says "I knew it" is an example of this.
And honestly, it's a well executed one as well bc even if you didn't see Ultron at all, you'd be able to deduce that Cap being worthy had been foreshadowed previously. Its the kinda callback that might interest me enough to eventually watch Ultron and appreciate it despite seeing it way out of order after the fact.

Besides, phase 5 was doomed to shit the bed from the go imo

"Multiverses mean that death isn't permanent (except for Stark and Aunt May)"
"Who are all these micky mouse club house looking D-Listers, and why are they all getting their own miniseries?"
"He's still the fucking falcon, idk who they think they're fooling. Feel bad for Anthony Mackey honestly."
"They had to flat out bail on making a new blade movie? That's unfortunate, but we got a girl hulk that could twerk!"

I think you could argue that the wheels were starting to wobble pretty hard in Endgame imo. S:NWH has been the only highlight since imo
