Nightcrawler is originally stated to be from a small village called Winzeldorf in the German state of Bavaria. In the X-Men animated series, it is said to be Neuherzl, and in the movie X2, he makes repeated references to his time in the Munich circus, though it is never explicitly specified from where he originated.
Nightcrawler occasionally uses an image inducer to disguise his true appearance with a holographic form.
Nightcrawler's real name is Kurt Wagner, some people have also called him by the name of Fuzzy Elf.
Shining yellow eyes, with no visible pupils
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 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.
Nightcrawler is an Olympic-class acrobat thanks to his flexible spine that allows him to perform contortionist-like feats and to go long periods in a semi-crouching position without injury. He is a skilled hand-to-hand combatant and a master at fencing, which he can even perform with his tail, which is strong enough to support his entire body weight.
Nightcrawler formerly wielded a pair of swords.
