While most fans love Rick & Morty for the titular characters, there is a bevy of supporting characters that help make the show as incredible as it is. Many of these characters are secondary or recurring characters, but some of them are only seen once and still manage to make an impression.
Most of these additional characters sound familiar to fans as they are voiced by well-established actors and voice actors. Some of the superstars among the supporting cast are fairly well-known among fans, but there are a few whose corresponding actors would surprise even die-hard fans.
10 Jerry Smith Is Voiced By Chris Parnell From Anchorman & Archer
Jerry is a cowardly kind of guy that typically gets walked all over. Unfortunately, this is the type of role Chris Parnell has been typecast in. While he's portrayed the brave and somewhat annoying Progressive Insurance Box, most fans know him from shows.
Parnell served as Garth Holiday in Anchorman who was the assistant to Ed Harken (the Channel 4 News Team's boss) that constantly got taken advantage of. Parnell's biggest voice acting role is a character called Cyril Figgis from the FX series Archer. Figgis is often the butt of the joke in the ISIS office and always plays second or third fiddle to the titular hero of the series.
9 Beth Smith Is Voiced By Sarah Chalke From Scrubs & Roseanne
One of Sarah Chalke's earliest roles was playing Becky on the sitcom Roseanne back in the 1990s. She later moved on to the medical comedy Scrubs playing the role of Dr. Elliot Reid, who was a fairly major character during the show's run.
Chalke has been in various shows and series, but since Scrubs she is most well-known for providing her voice to the character of Beth Smith. Chalke provides the right combination of confidence and faking it until making it for Beth's character.
8 Squanchy Is Voiced By Tom Kenny; Spongebob Squarepants Himself
Squanchy is an old friend of Rick's who uses his own name - and variations of it - as the Smurfs do in their daily vocabulary. While he is a bit of a goofy character with some less than reputable habits, he can turn himself into a Hulk-like beast capable of taking on platoons of enemies.
Tom Kenny, most famously known for his portrayal of Spongebob Squarepants, provides a wild and zany voice for the ridiculous character. He also voices other minor characters on the show. With Kenny's talent, it's no surprise the creative team would want to use him as much as they can.
7 The U.S. President Is Keith David & General Nathan Is That '70s Show's Kurtwood Smith
Keith David's voice is one that most fans would instantly recognize as David has been acting and voice acting for decades. He has lent his voice to children's cartoon characters such as Goliath from Gargoyles and was even featured on several episodes of Mister Rogers' Neighborhood. Some of his more recent characters are from popular shows like Adventure Time, Community, The Flash, and Final Space.
Kurtwood Smith is another long-time actor, but he is certainly most well-known for his portrayal as the tough yet hilarious Red Foreman from That '70s Show. Smith's voice is instantly recognizable from the moment General Nathan delivers his first line.
6 A Couple Of Fourth-Dimensional Beings Are Voiced By Mad TV Alums Keegan-Michael Key & Jordan Peele
This first Time Cop is voiced by Keegan-Michael Key who, since Mad TV, has had quite a successful career as an actor and voice actor in shows like Friends from College, Whose Line Is It Anyway?, and Archer. He is also known for his impersonation of Penn State's (Key's alma mater) football coach, James Franklin.
The second Time Cop is voiced by Jordan Peele who not only starred on Mad TV along with Key but is also the co-creator of their sketch comedy show Key & Peele, which was quite successful. Peele has since pivoted toward the horror/suspense genre while serving as a director instead of an actor, most notably directing Us and Get Out.
5 Rick's Ex-Girlfriend Unity Is Voiced By Mad Men's Christina Hendricks & Her Rebound Beta-Seven Is Voiced By Comedian Patton Oswalt
While Hendricks has done plenty of work since the 1990s, most of her work has been live-action, so some fans may have had a hard time recognizing her voice as Unity. However, she is prominently featured throughout the episode, so eagle-eared fans may have recognized the voice of the Mad Men star.
Unity's rebound boyfriend is another hive-mind alien known as Beta-Seven, who is voiced by Patton Oswalt. Oswalt is formally known as a comedian, but with such a unique voice he is often selected for animated characters. Oswalt's animated resume includes characters from hits such as Static Shock, Ratatouille, Kim Possible, Archer, We Bare Bears, Happy!, and Marvel's M.O.D.O.K.
4 Zeep Of The Microverse & Anatomy Park's Dr. Xenon Bloom Are Voiced By Former Daily Show Correspondents Stephen Colbert & John Oliver
When Rick and Morty travel inside Rick's car battery, they meet a scientist by the name of Zeep who appears to be on Rick's level of intelligence. Zeep is voiced by Stephen Colbert and the snarky sarcasm Colbert is known for fits very well for the character. Zeep's story was left open, so fans are hoping to see Colbert reprieve his role in the future.
Another The Daily Show correspondent from the Jon Stewart era is John Oliver. Oliver lends his voice to a one-off character called Dr. Xenon Bloom. While Bloom is certainly dead in the show, that doesn't mean Oliver can't return to voice another unique character.
3 Abradolph Lincler Is Voiced By Maurice LaMarche From Futurama & Pinky And The Brain
Maurice LaMarche is a significant voice actor who has played hundreds of different characters during his long and lucrative career. While it's hard to pin down where people might know LaMarche from, most fans have seen or at least heard of both Futurama and Pinky and the Brain.
In the latter, LaMarche plays the genius known as Brain who tried to take over the world every night with his comrade, Pinky. Futurama showcases LaMarche's range as he plays multiple characters with unique voices such as Lrrr, Calculon, Morbo, Kif Kroker, Donbot, Clamps, Walt, Hedonismbot, and others.
2 Summer's Boyfriend, Hemorrhage & Morty's Girlfriend, Planetina Are Voiced By Community Stars Joel McHale & Alison Brie
Considering Dan Harmon was the creator of Community, it's no surprise some easter eggs have made their way into Rick & Morty. When Rick, Morty, and Summer end up in a Mad Max-style post-apocalyptic world, Summer ends up in a domesticated relationship with the leader of the local cannibals. Fans of Community are quick to notice Joel McHale's voice as Hemorrhage, even from under the bucket.
Morty falls in love with the female version of Captain Planet and he is all for helping her save the planet until her methods become less than orthodox. Alison Brie has the perfect voice for this character, and fans of Community are likely to realize the cameo on the first watch.
1 Fart & Glootie Are Voiced By Jemaine Clement & Taika Waititi From What We Do In The Shadows
Jemaine Clement is probably most well-known for his participation in Flight of the Conchords, but he has also shown up in a few other places such as What We Do in the Shadows and Legion. As Fart, Clement's singing talents are put on display throughout the episode though the character ends up being fairly dangerous, prompting Morty to destroy him.
Taika Waititi also lends his voice to a character on the show whose name is Glootie and all he wants to do is desperately develop an app. Waititi is fairly well-known now thanks to his directing of Thor: Ragnarok, but his real big break came from What We Do in the Shadows which is a mockumentary on vampire culture which was so successful that FX adapted a television series after the film's release.
