octurne is the daughter of Nightcrawler. She comes from a reality where Wolverine has accidently killed Professor X and Kurt serves as field leader for the X-Men. Nocturne's original creation came about for a special one-shot called 'Millenium Visions'. Various creators came up with alternate versions of the X-Men. Some of these visions where choosen and made it to the comic page. Nocturne is the only member that made it out of her grouping. But she is different than her original design. In her debut, the blue mutant had no tail and sported Dreadlocks in her hair. Which may have been a concious effort on the creators side to differetiate her from Nightcrawler.
The Exiles have been gathered to set things right in various alternate realities. Each member has been choosen, because in their own reality something has gone wrong. The resulting changes alter bordering realities, changing the neighbooring realities, and so on. Nocturne must prevent Mystique from killing Nightcrawler, or she will cease to exist.
She shares many of his physical characteristics. But she has not been shown to possess any of her father's powers. She has limited telepathy, the full extent of which has not been determined. In addition, she can literally enter another person and control his/her actions. The person being possessed has no knowledge, and remains comatose for a duration once Nocturne leaves the body. Her last ability allows her to fire small bolts of energy at her opponents. She has dubbed them as 'Hex Bolts', as a kinda of tribute to her mother (The Scarlet Witch).
