Anyone know the Darkwing Duck episode that reveals Megavolt's origins?

I know, I'm a dork for asking, but I have to know if there even IS an episode that explicitly tells us of Megavolt's origins. I've seen one for Bushroot and that Liquidator guy, but Megavolt was the real villain I remembered from my childhood, other than Negaduck. I HAVE to know if these characters, but mainly Megavolt, have origin episodes of their own, and where I can find them (hopefully on the Net).
