Illustrators get used to receiving requests for drawings, especially as they develop their skills around friends and family members who feel requests are the best way to encourage a budding artist.
But those encouraging folks don't ask the artist to draw sick and twisted scenes featuring pop culture characters in sexual and/or gratuitously violent situations, at least not in public.
However, any artist who has worked the fan con circuit, sold their artwork online or taken commissions knows there are sick people out there looking for an artist to draw the stuff of nightmares.
Tom Fowler, artist/writer for Rick and Morty, was asked to draw a gross scene featuring Sauron, the Pterodactyl man from the Savage Lands, hypnotizing a teenage Storm into becoming his sex slave, akin to this panel:
Tom drew up a much tamer version for that weirdo, stating "I'd robbed this creep of his boner, and that's the real satisfaction that a cartoonist should feel".
Believe it or not the requests aren't always sexual- Tristan Jones, artist from ALIENS: Defiance, one got this request:
There was this guy that asked me to draw him, which is usually an immediate no from me on the spot at conventions, but as Jack Skellington (whatever that meant, I assumed it meant drawing Jack slightly heavier set and with this dude's hair) as a Ghostbuster, busting the ghost of his mother (who he had a photo of) from Jack's reindeer sleigh.
But then he talks about a different request which was racy to say the least...why, perverts, WHY?
