The Frequency Fiends - S3.E6

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!
