Nightcrawler is a mutant who can teleport by opening a portal into another dimension, travelling through it via an unconscious direction-finding sense, and returning to his own dimension. When teleporting, Nightcrawler leaves behind a small portion of the atmosphere of the other dimension that escapes with a muffled “bamf” sound and smells of brimstone. On returning, his power automatically displaces any extraneous liquids and gases.Nightcrawler can easily teleport north south along Earth's magnetic lines of force. However, teleporting east west against them or teleporting vertically is more difficult. Under optimal conditions, Nightcrawler can teleport 2 miles east west, 3 miles north south, and 2 miles vertically if he exerts himself. Nightcrawler's momentum is retained when teleporting, so he arrives with the same inertia he left with. He can reduce this by teleporting short distances in the opposite direction.Nightcrawler has a limited unconscious extrasensory ability that prevents him from teleporting into any area that he cannot see or has not seen in the past, as doing so runs the risk of injury or death by materializing partially or entirely within a solid object.Through practice, Nightcrawler has increased the mass he can teleport with him, though the limit to the amount of weight he can carry when teleporting and the distance over which he can teleport with such additional loads are unknown. Teleporting with Nightcrawler often leaves a passenger feeling weak and nauseous.Nightcrawler is also able to cling to solid surfaces via his hands and feet. He can also render himself nigh-invisible in shadows by manipulating the ever-present portal to the dimension he teleports through so as to bend light around himself.
