These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Old Man Logan
Crosses the Line Twice: Red Skull's last words before Logan chops his head off? "Don't make me laugh. You haven't got the guts".
Logan escaping the White House with the Iron Man suit.
The rampage against the Hulk Gang.
And on the villains' side we have Mysterio, a villain who was mostly considered harmless if he wasn't backed by a team, being responsible for the death of all the X-Men and for completely breaking Wolverine for 50 years. Horrifying, yes, but also a very big accomplishment for a "harmless" villain.
The Venom symbiote merged with a Tyrannosaurs. Nothing else needs to be said.
