 Colleen was born in the mountains of Honshu, Japan, to Professor Lee Wing (a teacher of Asian history at Columbia University) and a mother whose ancestors were samurai and daimyōs. After her mother's death, Colleen's late maternal grandfather Kenji Ozawa taught her the ways of the samurai, in which she later became very skilled. Professor Wing learned from a monk that young warrior Iron Fist would come from that land to seek vengeance on his father's killer and sent Colleen to meet him. Professor Wing and Colleen befriended Iron Fist, and Colleen has acted as his ally in many of his exploits. In Colleen's first appearance, she met Iron Fist, and she then aided Iron Fist in battling the Cult of Kara-Kai. Years later, Colleen went back to New York City to visit her father there. Upon arrival, she got caught in a gun battle by the local Manhattan police and some thugs. Luckily, she was rescued by officer Misty Knight, who eventually became her best friend. Later, when Knight's right arm was severely injured by a bomb explosion and was amputated, Colleen encouraged Knight to rise above her depression and return to an active role in life. Colleen and Knight formed a partnership as private investigators and called their firm Nightwing Restorations, Ltd. Due to Wing's samurai-style training and both partners' expertise in the Asian martial arts, they were dubbed "the Daughters of the Dragon."
 Colleen was at one point captured by Master Khan and Angar the Screamer, who turned her into a mesmerized slave. Colleen battled Iron Fist, who finally freed her from their mental control. Colleen then teamed with Misty in opposing agents of the criminal Emil Vachon in Hong Kong. Colleen was captured by Emil Vachon, however, who turned her into a heroin addict. She was rescued by Misty Knight, overcame her addiction, and took vengeance on Vahcon. Colleen then fought Davos, the second Steel Serpent, and met Spider-Man.
 Colleen later aided the X-Men and Sunfire in battling Moses Magnum in Japan. She accompanied the X-Men to Canada, and made romantic overtures towards Cyclops, whose girlfriend Jean Grey was presumed to be dead at the time. She was held prisoner by Arcade soon after that.
 Colleen later met the actor Bob Diamond, one of the Sons of the Tiger. She then battled Constrictor and Sabretooth. Professor Wing then regained his memory, and Colleen's training in samurai skills by her grandfather was revealed. Colleen then began a romance with Bob Diamond. She was shot by Warhawk, and later fought the Constrictor again. She was briefly turned to glass by the second Chemistro, and was soon returned to normal. She then fought Fera (now Ferocia). Colleen later temporarily ended her friendship with Misty due to the latter's romance with Tyrone King. Colleen was next transported to K'un-L'un. She killed Chiantang the mystic dragon. She then attended the funeral of an impostor she believed to be Danny Rand.
 Some time later, Colleen saw a second Danny Rand impostor on television. She confronted this impostor, who was actually the Super-Skrull. She was present at the exhumation of the corpse of the first Danny Rand impostor.
 After her relationship with Bob Diamond ended, Colleen once again started up the Daughters of the Dragon organization with Misty as bondswoman.
 Succeeding in that during the 2006 "Civil War" storyline, she and Misty create the new Heroes for Hire due to the urging of Iron Man, Reed Richards and Spider-Man.
 Colleen has been identified as one of the 142 registered superheroes who have registered as part of the Initiative. In the group's most recent mission, Colleen Wing and Tarantula were offered to the Brood Queen by their possessed teammate Humbug When Shang-Chi and the other heroes come save them, Colleen is in traumatic shock; she is further agitated when Moon-Boy, whom the group had been hired to apprehend for S.H.I.E.L.D. is taken into custody by Paladin. Misty had made a deal with him in order to find both her and Tarantula after their capture. Colleen, deeply upset by this, left the group as a result. Heroes for Hire disbanded in the aftermath of this.
 Following Daredevil's takeover of Hell's Kitchen during the "Shadowland" storyline, Misty, Colleen Wing, Iron Fist, Luke Cage, and Shang-Chi confront him in attempt to stop him without violence. After a commotion happens elsewhere in his castle, he attacks the group, believing they are responsible. Days after the fight, Colleen is contacted by Daredevil, offering information about her mother. Upon visiting him again, he reveals to her that her mother actually led a resurrected Hand group of all swordswomen called "the Nail". Colleen's mother and the Nail were eventually assassinated by one of The Hand's enemies. Daredevil then asks her to lead a new incarnation of the group. She eventually accepts and meets the Nail consisting of Black Lotus, Cherry Blossom, Makro, and Yuki. Colleen later betrays the Nail and has to defend herself against them.
