Professor Moliarty was a diminutive mole who tried to block the sun using his invention, the Kineto Beam, which would effectively plunge St. Canard into eternal night and allow his entire race to storm the surface and conquer the city. He was stopped by Darkwing Duck, who destroyed the Kineto Beam and sent Moliarty and his fellow moles scurrying back underground where they came from. In trying to evade Darkwing during a future encounter, Moliarty dug straight through the planet and ended up in Kung Pow City. The Masked Mallard followed him anyway, and Moliarty was finally caught and turned over to the authorities in Kung Pow.

Darkwarrior Duck uses the invasion of Darkwings to go after the criminals of St. Canard. Moliarty and Tuskernini are his final victims before Quiverwing Duck stops him. Suff-Rage selects Moliarty for her League of Barely-Remembered Supervillains, an illusion for Darkwing Duck and Launchpad McQuack to fight and either be defeated or distracted by. The illusion of Moliarty wields his trademark bazooka against Darkwing during a one-on-one round. As with the others, Moliarty is defeated when the group is caught in a curtain. Just as Darkwing gloats, Suff-Rage reveals they were only an illusion.
