Rick Sanchez is the co-eponymous main character and leading protagonist of the show. He is a genius scientist whose alcoholism and reckless, nihilistic behavior are a source of concern for his daughter's family, as well as the safety of their son, Morty.
Not much is known about Rick's life before his current state seen in the show except for a few things that have been vaguely mentioned in the series. It has been mentioned multiple times that Rick has been absent from the family for at least fourteen years and it wasn't until one year before the events of "Something Ricked This Way Comes" when Rick finally returned to the Smith house on January 15th. The reason for his absence is unknown to the rest of the family.
In the Pilot episode, Rick told Beth that he loved the eggs that she made him and that her mother would have loved them too if she were still there. In the episode Rick Potion #9, it is revealed that Rick has a very pessimistic worldview, informing Morty that love is "just a chemical reaction that compels animals to breed", advising him not to continue the cycle of love, marriage and heartbreak that he had to go through and that his parents would likely go through, encouraging him to direct his energy towards science. This could imply that the woman he married before is either divorced and/or deceased as of now. In the same episode, he and Morty leave their original dimension (Dimension C-137) in favour of the one they currently reside in.
In the episode Get Schwifty, it was revealed that when Rick was somewhere in his college years or in his 20's, he, Birdperson, and Squanchy were in a rock band called "The Flesh Curtains".
Rick is 60 years old and currently resides in his room in the Smith house. In the garage, he works on his inventions and scientific formulas and tests them out, traveling to other dimensions, building various robots and devices, and causing general mayhem in different parts of the universe
In the episode "The Wedding Squanchers", Rick willingly turned himself over to the Galactic Federation and was sent to one of their maximum security prisons. He currently resides there, with little chance of bail, parole or escape.
Mortimer "Morty" Smith Sr. is one of the two eponymous main protagonists in Rick and Morty. He is the grandson of Rick and is often forced to tag along on his various misadventures. Morty attends Harry Herpson High School along with his sister, Summer.
Although the information is easily accesible, not much has been revealed about Morty's past life. Currently, Morty is 14 years old, and as of the beginning of the series, Rick Sanchez had been mysteriously missing from the family for a total of 14 years. It is unknown if Morty's birth and Rick's disappearance are linked to each other, but it has been shown on two seprate occasions that Rick knew Morty when he was only a baby. In the episode "Close Rick-Counters of the Rick Kind", one of Rick's happy memories of Morty was picking him up as a baby. In the episode "Get Schwifty", a picture on Birdperson's wall depicted Rick holding a baby, who, although had an ambiguous identity, was very likely Morty at that same age. In the episode "Raising Gazorpazorp", Beth accidentally admitted that when Morty was a baby, Jerry filled Morty with his own insecurity, turning him into the worrying coward he is today.
Summer Smith is the daughter of Jerry Smith and Beth Smith, the older sister of Morty Smith, the granddaughter of Leonard Smith, Joyce Smith, Rick Sanchez and Mrs. Sanchez/Diane Sanchez, the great-granddaughter of Rick's Father and a unnamed woman, and the great-niece of the Unnamed Uncle, she currently acts as the older sister and the granddaughter of the Morty Smith and Rick Sanchez from Dimension C-137. She is the only other member of the Smith Family to be aware of that fact.
Summer is a teenage girl of average height, thin build, and wide hips. She has a light skin-tone, and shoulder-length red hair, she has an oval head and pointed nose. Her most common outfit has been a pink tank-top, white capri-pants, and black slip-ons. She usually has her hair pulled back in a ponytail.
Squanchy is a cat-like anthropomorphic creature that was invited to Rick and Summer's party in "Ricksy Business". He is a recurring character in Rick and Morty, and very good friends with Rick, sharing his love for alcohol. Morty and Jessica first meet Squanchy engaging in auto-erotic asphyxiation masturbation in Morty's garage. This marks the first among many things he refers to as "squanching."
In "The Wedding Squanchers", after Tammy reveals herself as a deep cover agent for the Galactic Federation and the wedding reception is ambushed by Gromflomites, Squanchy tells Rick to save his family and get out of there before pulling out one of his teeth and breaking it in half to consume a green liquid substance which subsequently turns him into a giant version of himself with superhuman strength and endurance. At the end of the episode it is hinted to that Squanchy may have died in the fight against the Gromflamites when Rick drops the photo of Birdperson, Squanchy and himself. This hint is reinforced in the post credits scene of "The Rickshank Rickdemption" when Tammy is revealed to be alive and unharmed as Squanchy was last seen fighting her.
Jerry Smith is the husband of Beth Smith, the father of Summer Smith and Morty Smith, and the son-in-law of Rick Sanchez and Mrs. Sanchez/Diane Sanchez, he is also the son of Leonard Smith and Joyce Smith, and the nephew of the Unnamed Uncle, he currently acts as the father and the son-in-law of the Morty Smith and Rick Sanchez from Dimension C-137, respectively. He shares the same history as his C-137 counterpart until the Cronenberg disaster, where it was averted in his dimension. Jerry always tries to think of the best interest of the family, but his attempt to be the patriarch of the family can often be misguided by his self-centered nature. This causes him a great deal of conflict with Rick, as his father-in-law clearly has no respect for him whatsoever.
Beth Smith (née Sanchez) is the daughter of Rick Sanchez and Mrs. Sanchez/Diane Sanchez, the wife of Jerry Smith, and the mother of Summer Smith and Morty Smith, she is also the daughter-in-law of Leonard Smith and Joyce Smith, and the granddaughter of Rick's Father and a unnamed woman. She currently acts as the mother and the daughter of the Morty Smith and Rick Sanchez from Dimension C-137, respectively. She is currently employed as a veterinary surgeon at St. Equis Hospital. Characterized by a superiority complex and abandonment issues, Beth gradually came to struggle with her husband over his contributions to their marriage, due in part to his lower-level position and subsequent employment, further driven by her father influencing her feelings of superiority. Since their divorce, she has focused on raising her two children. However, by the finale she decides to reconnect with Jerry and they are living together with their children and her father.
Mr. Poopybutthole is a long-time family friend of the Smith Family. Rick clearly considers him to have long been a dependable person, although it's uncertain how long they've known each other. He made his first appearance in the episode Total Rickall. He is voiced by Justin Roiland.
Mr. Poopybutthole is a very good friend to the Smith Family, from another dimension (where he is a planet wide superstar) who has taken refuge with the Smith's so he can live a normal life [as started in the comic series 'Lil Poopy Superstar' issue 1-5], he is described as a long-time friend of the family. He is shown to have accompanied Rick and Morty on multiple adventures as well as experienced many great moments with the rest of the family. He is such a fond person to the family that Beth can't recall a single bad memory of him.
Mr. Poopybutthole first appeared in the episode Total Rickall, where he was visiting the Smith Family when alien parasites started inserting fictitious good memories into their minds in an attempt to take over the world. Along with the rest of the family, Mr. Poopybutthole had to help the family figure out which new family friends were real and which ones were fake. Morty realizes that the Alien Parasites could only implant good memories into a person's mind, so every family member who had no negative memories affiliated with them was killed. This results in Beth Smith silently questioning whether or not Mr. Poopybutthole is actually one of the many parasites that made them believe they were long time friends. Beth pulls out one of Rick's laser guns and shoots Mr. Poopybutthole in the chest, blasting him across the room onto a wall. The rest of the family panic and Beth retreats into the kitchen and haphazardly pours a glass of wine with eyes filled with tears as Mr. Poopybutthole awaits an ambulance while bleeding heavily.
After the credit sequence, Mr. Poopybutthole is shown slowly recovering inside the hospital. After telling the doctor that he no longer wishes to see the Smiths at this point in time, the doctor tells Beth that's he's sorry that "They never had any bad memories of him."
Mr. Poopybutthole returns in the post-credits epilogue of the episode The Wedding Squanchers, where he was shown to have just watched the same episode as the viewer. He then turned to the viewers and talked to them about the episode. He was shown to be walking with a cane from the events of Beth shooting him in his previous appearance. Mr. Poopybutthole also swallows his (what are assumed to be) painkillers, pouring them into his mouth, without any water. He ended the episode, telling the viewers to tune into season 3 of the show to see how things would turn out for Rick and the Smith Family.
Mr. Poopybutthole's next appearance was the ending of The Rickchurian Mortydate, wherein he gives a similar teaser for the next season as he did in The Wedding Squanchers.
Mr. Poopybutthole's final appearance was actually in a video released by Adult Swim called "The Poop in my Pants," which is a more sadly directed video of Mr. Poopybutthole looking through a book of all his life experiences, revealing his past.
Mr. Meeseeks (voiced by Justin Roiland) is the name of all the Meeseeks summoned by activating a Meeseeks Box. The Meeseeks appear in the fifth episode of the first season, "Meeseeks and Destroy". They are known to inhabit planets across the universe.
Meeseeks are creatures who are created to serve a singular purpose for which they will go to any length to fulfill. After they serve their purpose, they expire and vanish into the air. Their motivation to help others comes from the fact that existence is painful to a Meeseeks, and the only way to be removed from existence is to complete the task they were called to perform. Physical violence cannot eliminate them.
They typically live for no more than a few hours, and thus two days is an eternity for Meeseeks. The longer the Meeseeks stay alive, the more sanity they begin to lose. Rick warns the Smith family to keep their tasks simple.
If a Meeseeks is not given a purpose at the beginning of its existence it seems to default to taking the purpose of the Meeseeks before it. This is seen when a Meeseeks created for Jerry created another Meeseeks then ordered it to kill another Meeseeks it was in argument with which the resultant Meeseeks attempted to avail. The Meeseeks then wildly began pressing the box without giving orders and all the resulting Meeseeks began trying in vain to kill the rest of the Meeseeks.
Birdperson, currently known as Phoenixperson, is a recurring character in Rick and Morty. He is an old friend of Rick's and has seemingly known Morty since he was a baby. He attends Rick's party looking for a new mate after ending his soul-bond with his previous spirit-partner. At the end of the episode, he gets back in the saddle with one of Summer's high school friends, Tammy.
Birdperson first appears in Ricksy Business, where he attends Rick's party and hooks up with Summer's friend, Tammy. He is also one of the very few party-goers who remains behind to help clean up, although he may have just been waiting for Tammy to be ready to leave.
When Morty shows his frustration at the party's mess as it would mean no more adventures with Rick if his parents see the house in this state, Birdperson informs Morty that "Wubba lubba dub dub" means "I am in great pain, please help me" in his native language. Morty is skeptical that Rick actually means this, though this knowledge spurs him to eventually press Rick into action to preserve their ability to go on adventures together.
Birdperson later reappears, along with Tammy, in the episode Get Schwifty, where he saves Morty's life after the latter jumped through numerous, hostile dimensions before collapsing from exhaustion. He explains to Morty that leaving Rick was a "dick move", and that Rick really does care about him. Furthermore, if it wasn't for Rick, he [Birdperson] would be dead and would never have met Morty. He then recharges the Portal gun and sends Morty back to Rick.
In "The Wedding Squanchers", he and Tammy get married and have a huge wedding party. During this time, he confessed to Beth that he and Rick are wanted by the Galactic Federation for committing "crimes in the name of freedom" which Beth shrugs off. Shortly after, during the reception, Tammy reveals herself to be a member of the Galactic Federation secret service and shoots Birdperson multiple times, followed by a shootout with the rest of the criminals in the room.
Birdperson makes a cameo appearance in "The Whirly Dirly Conspiracy", in the form of a small statue that can be seen in the background.
Until her identity was revealed to be false, Birdperson was a devoted love interest to Tammy. He was calm and conservative while she had no filter in the things she said, no matter how inappropriate. It was revealed in the commentary for Get Schwifty that the creators were displeased with how the way things ended, finding humor in their brief relationship. Harmon and Ridley in particular considered recreating that formula in some way, admiring the dynamic between Tammy and Birdperson.
Scary Terry is a character that appeared as the secondary antagonist in the episode "Lawnmower Dog" and the comic story Morty and Rick in: Mortballs. After a failed attempt at killing them, Scary Terry retreats and heads home. While he is asleep, Rick and Morty incept his dreams and befriend him, he is also the husband of Melissa, and the father of Scary Brandon.
