Misty Knight was a rising star with the NYPD when she was seriously injured preventing a bomb attack that forced the amputation of her right arm. Rather than take a desk job, she resigned from the police force, though she remained good friends with her long-time partner on the force Rafael Scarfe.
Tony Stark provided her a bionic arm which endowed her superhuman strength. Soon after that, she met Spider-Man and then Iron Fist. Misty teamed with her friend Colleen Wing in fighting the criminal Emil Vachon in the Hong Kong area. She saved Colleen from an attempted rape. She then set up a private detective agency with Colleen entitled “Nightwing Restorations Ltd.” Soon after she first met Iron Fist, the two crime-fighters fell in love. Misty conducted undercover work against the crime lord John Bushmaster. She aided Iron Fist, Spider-Man, and Colleen Wing against Davos, the Steel Serpent.
