Nightwind is a fictional mutant character in the Marvel Comics Universe. Her first appearance was in Generation X #53.
Adrienne wanted the sword for herself and sent the mercenary Paladin to get it, but the Rising Sons fought him off and left him for dead. Paladin returned alongside Generation X members Jubilee, Skin, Chamber, Synch and Husk.
This led to a confrontation with Generation X where Nightwind ambushed Chamber and almost killed him by knocking him out of an apartment window. She then jumped out of the window herself and boarded a train with Noy on it. When the Generation X members made their way onto the train and split up it was Synch and Skin who found her first. If not for Synch's ability to sense mutagenic auras they might have been killed, but Synch copied her powers to battle her. Although Synch was able to copy her powers he was unable to copy her skill and she proved herself to be the superior fighter to Synch. Before she was able to finish her battle Skin used his abilities to suffocate her until she passed out.
When the mentally ill Scarlet Witch depowered over 90% of the world's mutant population on M-Day, Nightwind was among the many who lost her powers. This fact was confirmed in New Avengers #18.
