Darkwing's new weapon hits Gosalyn. Although she's perfectly fine, 3 new beings are created, all of which look like Gosalyn, but have powers based on different frequencies: Heatwave (red), Lightwave (Yellow), and Radiowave (Green). D.W. enlists Megavolt help, but an untrusting Darkwing messes things up (""Positive, Positive, POSITIVE!""). Now the 3 Frequency Fiends are combined into 1 super-being, and it's up to the combined efforts of D.W., Launchpad, Goz, and Megavolt to stop them!
F.O.W.L. rebuilds Taurus Bulba into a death machine, hoping to create a new agent from him. Bulba refuses their offer and burns only with the desire to have revenge on Darkwing. To make matters worse, a recent accident has Darkwing in a wheelchair. Can he defeat a new and improved Terminator machine in his condition?
D.W. gets the D-2000 super-computer! While it seems to be perfect, Launchpad feels it's replacing him as sidekick, and Gosalyn is fed up with not getting away with anything, and introduces it to Launchpad's soap-operas. Soon, even darkwing wants the machine gone when it falls in love with him. Darkwing finally tells the computer system it's getting unplugged when he gets to the tower, at which point it goes berserk and decides that if it can have D.W. noone else will!
Helping with Gosalyn's homework, Darkwing shows her famous Mallards from history. She sneaks back into time with Quackerjack's timetop and brings them to the present. None of them seem to be as great as they were thought to be. When Megavolt steals Darkwing and Launchpad's nervous energy, the failures have a chance to prove they are heroes at heart.
