During the final battle Wolverine winds up battling a mutant capable of regrowing his limbs seconds after Wolverine chops them off, every time, without fail. Wolverine beats the mutant by kicking him in the nuts with all of his strength and, while walking away, tells him to try growing those back.
For some, watching Wolverine never learn what happens when he (a man with a metallic skeleton) tries to attack Magneto (a man with total control over magnetism). Epic Fail doesn't even begin to describe it, even if it's part of the plan.
Watching Quill, a guy whose power is having spines that at their longest are maybe 2 inches long pop out of his skin and only onscreen kill is by poping his quills while hugging a female scientist worried about her boss, try to act like he's a badass with the powers of a God is hilarious. Particularly when he tries it with Magneto, who is at best mildly annoyed by him.
The X-Men suit up for war, but Hank seems to have put on a few pounds over the years.
Beast: I can't believe this used to fit me.
Becomes funnier when youngerHank appears where Hank indeed had fit physique in his younger days. Wolverine even called Hank as "scrawny kid" in Days of Future Past once.
The smirk and wink Magneto gives the people in the car as he lifts the Golden Gate Bridge. Smug Super, baby.
The driver of the car hitting the button to lock the car doors when Magneto walks by, as if that could stop him.
Kitty Pryde's takedown of Juggernautnote Bitch!: He charges after her, she runs through a wall, he gets close enough behind to get his unstoppable strength nullified by Jimmy's powers, and knocks himself unconscious plowing head-first into the wall at a full charge.
