Galvaduck

Galvaduck is the monstrous dark-side clone to Darkwing Duck, and a member of the Fang Empire since the real Negaduck was canceled from appearing. Originally, Galvaduck was the upgraded version of Darkwing's evil half. But after it remerged with Posiduck, Galvaduck ceased to exist. As of late, Emperor Fang, yet another copy of Scar and Sir Hiss's negaverse twin, has resurrected Galvaduck by creating a clone of Darkwing, splitting the clone in two, and then amplfying the dark half into a new Galvaduck while killing the posiive half in the process. Galvaduck has not appeared yet in the series.
