Launchpad McQuack Meets Lord Dominator is an unofficial, sketchy comic written and drawn by Cristina Blanco (then under the pseudonym of “Queenie”), set in the 2017 Continuum. It features Launchpad McQuack and Lord Dominator, also mentioning Wander and Scrooge McDuck.
Behind the scenes
This story, published as a fan work on tumblr in 2017 for free, was reblogged on Frank Angones and the Suspenders of Disbelief, with Angones being extremely supportive of the concept of these two characters of his meeting. Interestingly, a year or so after the release of this fancomic, Cristina Blanco “went professional”, penning the highly successful webcomic Audrey & Azimuth — now under her true name, but under the same blog where she had first posted the DuckTales comic.
The comic (along with Angones's approval thereof) is indication that Wander Over Yonder apparently exists in the same universe as DuckTales 2017, which the presence of the Rollerpin Martian in the show, and of an Oblivion Mirror in DuckTales 2017, already suggested.
Blanco would go on to create various other sketches featuring Launchpad and Dominator (progressively forming a romantic bond with one another), although, without Angones's endorsement, those cannot be considered canonical.
