Duckthulhu is a force of mystery. His very origin is shrouded in the clouds of time.
Duckthulhu was created by Ian Brill and James Silvani. It is a parody of H. P. Lovecraft's Cthulhu
Following F.O.W.L.'s collapse at the hands of Quackwerks, F.O.W.L. High command decides they need to do something very diabolical to make its Organization Fiendish again. They look through old texts and they learn of an ancient evil force which they can call upon. However, to summon this force, a purple pawn has to arrive on his own volition, as the ancient texts demanded. Duckthulhu's appetite demanded a character of high spirits and exaggerated self image, so they didn't have to look any further than to their old enemy Darkwing Duck. Steel Beak tricks Darkwing into thinking he had switched sides against this effort, but instead he was manipulating him into coming on his accord to F.O.W.L. Headquarters. Upon arriving, he is tied up and the summoning begins. However, much to the despair of the High Comand, when Duckthulhu is summoned it will not listen to the commands of F.O.W.L. or anyone else for that matter.
With its legion of hypnotized citizens of St. Canard, it attempts to attacks Darkwing. However, Morgana Macawber steps in and rewrites reality (no big) into this 50s or 60s sitcom, after which she was able to attack and defeat Duckthulhu. However, this attack also sent her elsewhere.
