The champion of St. Canard, Darkwing Duck began pursuing a superheroic life from childhood. A fan of comic books, young Drake Mallard was inspired by his meeting with a masked duck (actually his future self, which he later forgot about) to become a masked crimefighter named "Darkwing Drakie." By the time he was in his late teens, he officially became Darkwing Duck for the first time to stop his insane classmate Megavolt. In the years afterward, he set up a base in the Audubon Bay Bridge, and developed glory-hog tendencies; as a result of the latter, despite his (sometimes accidentally) successful superheroics, he was viewed as an annoyance by local authorities.
One day, he became involved in protecting young Gosalyn Waddlemeyer from the villainous Taurus Bulba. With the help of Launchpad McQuack, Darkwing was able to save her and stop Bulba. Thereafter, Darkwing adopted Gosalyn and resumed using his civilian identity for her benefit. Although he never lost his love of attention (or his occasional ineptitude), the assistance of Launchpad, Gosalyn and her friend Honker Muddlefoot made him a better crimefighter.
Darkwing has since battled many villains, most notably Megavolt, Bushroot, Quackerjack, Moliarty, Tuskerninni, and his evil twin, Negaduck. He has also worked with spy organization SHUSH (much to the consternation of senior agent Grizzlikof) against FOWL, and has had an on-again-off-again relationship with Morgana Macawber. Darkwing was reluctantly a member of the Justice Ducks, which included his sort-of rival Gizmoduck.
Darkwing Duck has no special powers, but he does have some training in martial arts, specifically Quack-Fu (but he's not as skilled as he thinks he is). Darkwing's equipment and paraphenalia include the Thunderquack (designed by Launchpad) and his favorite weapon, the Gas Gun (which he uses to make his dramatic entrances).
