While mutants and mutates (like the characters seen in the MCU) share the same comic book universe, the writers essentially compartmentalize the two. When people think of mutants, they usually think of X-men. MCU has its own brand of "mutant" in the Inhumans who I think are far more interesting anyway.This is why Marvel movies and Tv shows can never be up to their full potential. Because the term mutant is fully in Fox's control in a world literally designed around Mutants. Even Stan Lee said it when he came up for the idea of mutants "not everyone can be blasted with cosmic rays or build a suit or be a god." So he came up with mutants as a way to fill the world and tell more stories.
I don't think he could teleport the Hulk. From memory, and playing him in Marvel Super Heroes RPG many moons ago, he has a limit on the mass he can teleport. He also has a limit on distance.Nightcrawler is pretty powerful, he can beat a lot of people by just porting them somewhere they can not escape. For instance he could take out the Hulk pretty much instantly.
This was how he escaped from Genosha in Wolverine and the X-men, by chain porting back to the mainland.2-3miles. But can chain teleport. Remember a story with him teleporting to a boat off of Genosha or something. or was it he actually ended up teleporting across the Atlantic? by porting over and over again.
The lines of sight issue is the classic. "So he doesm't teleport into a solid wall and die."
in X2 he teleports out of the plane to save the one bitch and teleports back in. definitely didn't have a line of sight there.Not sure about his limit on mass, bit his limit on range is basically his vision. If he can see it, he can go there. I don't know how that works if, say, he is in new York, watching a live feed from the moon.
He knows he's teleporting out into open air, whereas when Storm talks him into teleporting into the Cerebro chamber, he has only a vague idea of what's inside. But you're right, rescuing Rogue was somewhat inconsistent with his 'i can only teleport where I can see'.in X2 he teleports out of the plane to save the one bitch and teleports back in. definitely didn't have a line of sight there.
it's pretty incredulous to think that with out a line of sight he knew exactly where Rogue's body would be, and additionally that he was able to teleport back into the moving plane. unless one of his super powers was enhanced mathematical calculation ability to calculate the trajectory of a moving aircraft, or if he was asian, which he isn't.Considering he was originally in the plane as a known location and saw her get sucked out of the plane which had a hole in it that's the least compromising example you could have used.
