History EnsembleDarkHorse / RickAndMorty

!!''WesternAnimation/RickAndMorty''
Since most of the side characters that aren't from Morty's school rarely, if ever, show up again after their first appearance, this happens a lot due to their [[EnsembleDarkhorse memorable designs and/or personalities]].

* Mr. Meeseeks who first appeared in "[[Recap/RickAndMortyS1E5MeeseeksAndDestroy Meeseeks And Destroy]]" seldom appears, but he's one of the most popular characters in the show.
* '''''[[AlternateSelf EVERY SINGLE ALTERNATE VERSION]]''''' of Rick and Morty themselves are bound to get this treatment, which may have been the main reason why ''VideoGame/PocketMortys'' was made (and in turn churned out even more Darkhorses).

* Krombopulous Micheal, the insectoid assassin that only appeared in "[[Recap/RickAndMortyS2E2MortynightRun Mortynight Run]]", is incredibly popular for being so upbeat about his job and doing it with such style.

* Scropon from episode "[[Recap/RickAndMortyS1E11RicksyBusiness Ricksy Business]]" has some fans as well due to his monstrous but very cool looking alien appearance and tragic backstory about his planet being destroyed. He was loved by some of the writers who drew early concepts on him with one such writer making a note saying that Scropon looked cool on one of the earlier concepts.
* Scary Terry from episode "[[Recap/RickAndMortyS1E2LawnmowerDog Lawnmower Dog]]" is pretty well-liked due to being a [[CaptainErsatz parody of Freddy Krueger]], a horribly bad PungeonMaster, and a surprisingly NiceGuy who's actually just a PunchClockVillain.

* Many critics have noted that Jessica could easily be developed into an interesting character in her own right, going off her casually amiable relationship with Morty, very quick adjustment to the weirdness surrounding the Smith family, and her lack of familial relationship to Rick, all of which could give her a unique perspective on their absurd adventures.

* Morty's teacher Mr. Goldenfold has his fans, if mainly due to his hilarious lines and [[{{Cloudcuckoolander}} odd personality.]] He eventually gets his [[ADayInTheLimelight Day in the Limelight]] in Season 7's "[[Recap/RickAndMortyS7E8RiseOfTheNumbericons Rise of the Numbericons]]".

** One specific example from episode "[[Recap/RickAndMortyS1E10CloseRickCountersOfTheRickKind Close Rick-Counters Of The Rick Kind]]" is [[spoiler:Evil Morty]], who's only appeared thrice so far, but is wildly popular for his memorable [[TheReveal reveals,]] complete with SugarWiki/AwesomeMusic for both (to the point that ''For the Damaged Coda'' is now considered to be his {{Leitmotif}}), and managing to [[spoiler:successfully escape and outsmart the main and alternate versions of Rick in his first appearance, and become president of the Citadel of Ricks without any still-living Citadel member figuring out who he really is or what he really wants in his second appearance]]. Fans rejoiced when he made his appearance in "Rickmurai Jack" and [[spoiler:finally became a direct threat to Rick and Morty, being revealed to have created thousands of Morty clones and using them to destroy the Central Finite Curve, the Citadel, and Rick and Morty so he can escape into realities where Rick is not the smartest man in the universe. Evil Morty is the definition of [[TheChessmaster The Chessmaster]]]].

** Twenty-six year old Morty from "[[Recap/RickAndMortyS5E10RickamuraiJack Rickmurai Jack]]" is rather well liked, despite only having a few seconds of screen time. He acts heroic in his brief time and is widely considered handsome.

* Mr. Poopy Butthole from episode #"[[Recap/RickAndMortyS2E4TotalRickall Total Rickall]]" has a lot of fans. His reappearance at the end of the season 2 finale was very well-received, and he was promoted afterwards to a recurring character.

* Morty's teacher Mr. Goldenfold has his fans, if mainly due to his hilarious lines and [[{{Cloudcuckoolander}} odd personality.]]

* Mr. Poopy Butthole from episode #"[[Recap/RickAndMortyS2E4TotalRickall Total Rickall]]" has a lot of fans. [[spoiler:His reappearance at the end of the season 2 finale was very well-received.]]

* Rick's arch-nemesis Mr. Nimbus, who only appeared in episode
"[[Recap/RickAndMortyS5E1MortDinnerRickAndre Mort Dinner Rick Andre]]", has a lot of fans for being a hilarious LargeHam and a great {{Foil}} to Rick.

* Mr. Poopy Butthole has a lot of fans. [[spoiler:His reappearance at the end of the season 2 finale was very well-received.]]
* Scropon has some fans as well due to his monstrous but very cool looking alien appearance and tragic backstory about his planet being destroyed. He was loved by some of the writers who drew early concepts on him with one such writer making a note saying that Scropon looked cool on one of the earlier concepts.
* Scary Terry is pretty well-liked due to being a [[CaptainErsatz parody of Freddy Krueger]], a horribly bad PungeonMaster, and a surprisingly NiceGuy who's actually just a PunchClockVillain.

* Noob Noob, the Mr. Poopy Butthole look-alike who [[ButtMonkey can't seem to catch a break]].
* Tony from the Season 4 episode "The Old Man and the Seat", is quite popular despite his single appearance, with many people admitting to liking his somewhat friendly and likeable but still subtle personality. [[spoiler:His death makes this even sweeter, as the scene of Rick grieving Tony [[ItMakesSenseInContext on his private toilet surrounded with various holo-recordings of himself]] is generally agreed to be an incredible TearJerker]].
* The Talking Cat in "Claw and Hoarder" for his mysterious nature. Many fans agree that his subplot with Jerry is better than the A-Plot of the episode.

* The gangsters also in "The Vat of Acid Episode", if for no other reason than their [[SeinfeldianConversation reaction to the apparent suicide]] provides some of the most hilarious portions of what is widely considered one of the best episodes of the series.
* Rick's arch-nemesis Mr. Nimbus, who only appeared in one episode, has a lot of fans for being a hilarious LargeHam and a great {{Foil}} to Rick.
* Similar to Morty's one-shot girlfriend from Season 4, Planetina instantly became a fan-favorite, with the added bonus of being her own character rather than a SatelliteLoveInterest.
* Of the five real [=GoTron=] pilots, Kendra is the most popular thanks to being the most prominent among them and for actually being rather attractive between her design and Animesque style (she's more cute than sexy, but she still has her fans). Helps that she was the only one of the original pilots to be named.
* Hermit Jerry has gained some popularity with fans for his TookALevelInBadass compared to the Jerry that we are familiar with, but also for his "TheReasonYouSuck" Speech to Morty, spelling out how many of the sociopathic traits associated with Rick he sees in his son. Whereas regular Jerry begs his children for validation, Hermit Jerry is repulsed by Morty's claim that he "improved" during the Cronenberg apocalypse. His expression of hurt and rage to Morty is perhaps among Chris Parnell's best voice work for the show, and made Rick Prime that much more of a HateSink for killing Hermit Jerry in TheStinger.
