[X-Men] How far can Nightcrawler teleport?
gpt
Since his inception, his powers have never been extreme. Nightcrawler used to get exhausted from jumps of anything over 100 feet. By the time he was an official part of the X-Men, he could make multiple jumps per second and travel up to two miles. He can jump blind, but it's exceedingly dangerous. Usually he has a pretty good idea of what it will look like wherever he is going.

Nightcrawler once escaped Genosha by making hundreds of jumps each a few miles long and just slightly above sea level. By the time he got to  Florida, he was exhausted.

Nightcrawler can take other people with him when he teleports but it is a nauseating trip and more difficult for him to do.

Nightcrawler can opt to teleport 'pieces' of things instead of something in its entirety. This being exceedingly fatal, it is not something he practices on living creatures. He needs to be touching whatever he teleports.

Nightcrawler's teleport is not direct. He passes through an interdimensional space nearly instantaneously. Theoretically, the longer he was able to stay in the interdimensional space, the further he could travel, but considering the negative biological effects of travel through this non-Euclidean dimension, this seems like an unhealthy step to take.

Finally, whenever Nightcrawler teleports, he leaves behind a puff of sulfur smelling smoke. This is probably an indication that the non-Euclidean dimension he teleports into is filled with sulfurous compounds that cling to his skin when he teleports and oxidize abruptly on arrival. (Indicating a volatile reaction.) This indicates an inhospitable atmosphere at the very least.
