In Rick and Morty's 'Total Rickall,' the Smith family contend with a species of psychic parasite that implant fake memories in their victims, inventing countless new members of the household. Tragically, these friends and loved ones are dangerous, and figures like the beloved Smith family butler Mr. Beauregard have to be wiped out to restore normality. However, one Rick and Morty comic proves that even though the Mr. Beauregard who was in the TV series was an alien parasite, the real, human version does exist.
In Rick and Morty: Go to Hell #5 by Ryan Ferrier and Constanza Oroza, Rick and Morty have ended up in Hell and are scrambling to get out. Morty finds himself standing before Satan, pleading his case as to why the devil should release his soul from the hellish afterlife. Before Morty gets into exactly why he doesn’t deserve to be trapped in Hell, Satan offers him a refreshment, calling to his butler Mr. Beauregard to bring them some food and drink. Later in the comic, Mr. Beauregard briefly shows up on-panel, proving that it is in fact the same character from the episode 'Total Rickall.'
Mr. Beauregard’s inclusion in Rick and Morty: Go to Hell is initially a confusing development, as fans believed Mr. Beauregard didn’t exist at all. The character was the generic creation of a parasite used to believably trick Rick and Morty's family into believing they had a butler. However, Mr. Beauregard appearing in hell implies that the butler actually did exist as a real person, and that person died and their soul was sent to hell. Mr. Beauregard's existence calls into question the nature of the parasites that entered Rick and Morty’s house, and how exactly they operate.
It's possible the parasites are somehow connected to Hell, or else that they can scan parallel universes, creating their 'characters' from people who do exist, but just in different worlds. It's also possible that they can base false memories on the memories of their victims, and one of the family met or at least saw in passing the real Mr. Beauregard at any early time. Finally, it's possible that the multiverse is simply so vast that the parasites just happened to recreate a real person, though this thought gets far stranger once some of the more bizarre characters like Ghost in a Jar and Pencilvester are taken into account.
Indeed, the biggest takeaway from the proven existence of a real-life Mr. Beauregard is the question of how many other parasites were based on real people or creatures. If Mr. Beauregard was based on a real butler someone in Rick and Morty’s family saw at one point in time, then maybe Sleepy Gary still exists somewhere, waiting to meet his perfect match in Jerry. Hopefully, the Rick and Morty comics or show will return to this dangling plot thread, especially because the human Mr. Beauregard was apparently so bad, he earned a spot in hell working for the devil himself. A Rick and Morty easter egg proves one parasite was also a real person, but so far this interesting development raises more questions than it answers.
