Beware of spoilers!
The principal of Morty and Summer's high school. A middle-aged, balding man with a shitty name that he constantly has to emphasize he has no relation to the female body part, Principal Vagina is a surprisingly level-headed person in such a messed up world.
- Dissonant Serenity: As stated in the description, he is very calm and brushes off stuff like hiring a vampire as a PE teacher as if it were an everyday thing.
- Drunk with Power: After establishing the Headism Religion.
- Embarrassing Last Name: But don't let that fool you, he's very much in charge. According to him, his best guess is that it's possibly Scandinavian.
- Pædo Hunt: After Morty tells him that Mr. Lunaris is from the moon, Vagina not only fires him but punches him for good measure, believing that Morty was implying that he was a pedophile.
- Suspiciously Specific Denial: When Frank Palicky is killed, he insists — completely unprompted — that there's no evidence a Latino student did it. Especially considering Rick is implied to be Latino.
Morty and Summer's math teacher.
- Angry Black Man: If Da Chief was teaching math in a suburban high school, he'd be this guy. Though this didn't really last past first appearance.
- Badass Teacher: Only in his dreams...and when rebelling against the Galactic Federation.
- Butt-Monkey: His existence is pretty sad both in and out of school.
- Characterization Marches On: Was presented as a typical Angry Black Man in his first appearance. He is shown as much calmer whenever he appears after.
- Ephebophile: Has a repressed attraction to Summer, and is in no particular hurry to stop Morty from rubbing his chest in the pilot.
- Fantastic Racism: The last episode of Season Two has him being the victim of this, with two aliens playing keep-away with his hat. The first episode of Season Three has him calling aliens "Insects" and rising up in rebellion against them.
- Paste Eater: He eats his own poop. Defied because he's going to therapy to get help for this.
- Rebel Leader: He seems to have spent the Galactic Federation's occupation of Earth hiding in the sewers and preparing for an uprising.
- Retired Badass: Despite leading an Anti-Federation Rebellion (see Rebel Leader and Badass Teacher above), afterwards he went right back to being a teacher.
- Took a Level in Badass: Season two ends with Earth being occupied by the Galactic Federation. In the first episode of Season Three, when said federation was collapsing into anarchy, Goldenfold emerges from a sewer manhole with a sniper rifle and several angry followers.Goldenfold: No longer will the insects have domain over surface world!
- The Ghost: He's dealt with entirely offscreen.
- Our Vampires Are Different: This is the first time vampires have been mentioned in the show, although Rick seems to take them for granted.
- Steven Ulysses Perhero: His choice of name wasn't exactly subtle.
- Too Dumb to Live: His vampire master thinks as much when he hears what his assumed name was.
A new guidance counselor at Morty's high school.
- Dark Is Not Evil: Despite looking like a typical cartoon villain, he was revealed to have been a respected marine officer and a guidance counselor.
- Driven to Suicide: He took his own life after being falsely accused of being a pedophile.
- Meaningful Name: His name is Gordon Lunas and he is accused of living on the Moon.
- Mentor Archetype: Invoked, but Ultimately subverted.Mr. Lunas: I look forward to helping guide you all towards a brighter future. I believe every student should shoot for the moon.
- Mistaken for Pedophile: Played for Drama. When Morty tells Principal Vagina that Mr. Lunas is "living on the Moon", the Principal doesn't understand that the accusation is meant to taken literally and assumes it is a euphemism for pedophilia, confronts Mr. Lunas, punches him in the face, and presumably fires him.
- The Nondescript: Apparently Morty described him as being a "regular dude". At his funeral, the only thing his brothers-in-arms can say about him is that he was a good marine and that "from a certain angle he looked like a smudge".
- Retired Badass: He's a retired U.S. Marine.
- Weird Moon: Morty thought he saw this guy on the moon ... it was just a smudge.
A popular and attractive girl in Morty's class. Morty is hopelessly in love with her but, unfortunately for him, she only rarely acknowledges his existence.
- All Girls Want Bad Boys: Played with concerning her and Brad. She hates how he always picks fights, and yet they're still together no matter what. It's possible though by "Big Trouble in Little Sanchez" that they have broken up as she goes with Morty to the dance.
- The preview for Season 3's episode 6, "Rest and Ricklaxation", she admits to having broken up with him at the start of the episode. She maintains that they're still broken up at the end, despite going to lunch with him.
- All Guys Want Cheerleaders: Jessica is shown to be a cheerleader in the 20th issue of the comics. In the same issue, Morty actively seeks to win her affections by becoming stronger and joining the basketball team.
- The Cheerleader: See All Guys Want Cheerleaders above.
- Cool Kid-and-Loser Friendship: Played with. While they aren't friends per se, Jessica is genuinely nice to Morty and seems to not mind his company, even going with him to the school dance in "Big Trouble in Little Sanchez". She also is impressed by the fact that he is a sidekick to his Mad Scientist grandpa.
- Further played with in "Rest and Ricklaxation", where she is willing to go on a date with him. When the detoxified Morty spearheads the date, instead of making an excuse about leaving, she admits that he would be bored of her. Later, she helps Rick get Morty back to normal, and while she insists it was because Rick was drunk-dialing her into it, she has some genuine care for him. The day after, she tells Morty that it's good to have him back.
- Flat Character: So far, she doesn't have much depth as a character and exists solely for Morty to have a crush on her. She has shown some hints though as seen below.
- Freaky Is Cool: In the pilot episode, she is impressed with Morty for coming into the cafeteria through a portal and in "Big Trouble in Little Sanchez" when Morty tells her that tiny Rick is his grandpa in the body of a teenager, her response is "cool".
- Gaussian Girl: Parodied in "Ricksy Business". Jessica is introduced this way, only for Rick to scold Slow-Mobius for messing with time to create the effect.
- Girl of My Dreams: She is the object of Morty's teenage desires and humid daydreaming
- Hidden Depths: She reveals herself to be far from shallow in "Ricksy Business," where she expresses her exasperation with her Jerk Jock of a boyfriend and says she only wants to date someone who is nice and sweet, though it doesn't stop her from leaving the party happily with him at the end.
- Jerkass Ball: She posts an Instagram selfie with her recently deceased grandmother in the background totally devoid of any grief. In the same episode, she considers providing affection to dying people as a worthwhile career, so she's not completely heartless.
- Nice Girl: Even if she isn't particularly close with him, she's never anything but pleasant to Morty and sees him as a friendly acquaintance, at the least. When detoxified Morty ruins their date by being overbearing and obnoxious, she stops herself from being rude and lying to him about needing to leave, instead saying he'd get bored with her at the speed he's now going... and she's immediately proven right. In the Season 4 premiere, she's even shown that she wants to make a career path out of being a hospice worker who comforts lonely elderly people as they die.
- Pet the Dog: She wants this as a career path, as she wants to be a hospice worker who comforts lonely elderly people as they die.
- Satellite Love Interest: She has almost no characterization outside of being Morty's crush, but "Ricksy Business" did add some depth to her. She finally gets a decent amount of screentime in "Rest & Ricklaxation", going on a date with Morty (which he torpedoes) and then aiding Rick in tracking him down— partly to help bring Morty back to normal, and partly because Rick wouldn't stop drunkenly calling to press her into it.
- Zettai Ryouiki: Grade C.
A student at Harry Herpson High School. He is a jock who plays football for the school and dates Jessica.
- Jerk Jock: Plays football and bullies Morty. He is even somewhat self-aware about his role:Brad: (to Morty after he awkwardly tries to chat up Jessica) Dude, stay in your league! Look at how hot she is. You don't see me going to a bigger school in a wealthier district and hitting on their prettiest girl!
Jessica: (rolls her eyes) Gee, thanks, Brad.
Brad: I throw balls far. You want good words? Date a languager.
A bully who appeared in the pilot episode of the series. Frank Palicky carried a knife around in school and threatened to make anyone who called his family poor pay the price for doing so. He was summarily frozen by Rick, then toppled over and shattered on his own, killing him instantly.
- Asshole Victim: Downplayed, despite being an an absolute lunatic, Frank's death is shown to traumatize Summer and results in the school being on edge for the rest of the episode.
- Ax-Crazy: Becomes angry enough over just ten seconds to try to "cut" Morty with a switchblade, right in front of everyone else in the hallway.
- Barbaric Bully: A greaser delinquent who threatens Morty with a knife over an imagined insult.
- Berserk Button: Don't call his family poor. Or say anything that might make him think you called his family poor. Or... it's probably best if you don't talk at all around him, actually.
- Expy: Of Biff Tannen from Back to the Future. Unlike Biff, however, Frank didn't last long.
- Greaser Delinquents: Leather jacket? Check. Switchblade knife? Check. Ducktail haircut? Check. The dude just looks like he's stuck in the wrong decade.
- Harmless Freezing: Subverted, Rick responds to Morty's request to unfreeze by saying the freezing is harmless. Shortly after they leave, the frozen Frank tips over and shatters into a million pieces, horrifying the students.
- Informed Poverty: He goes Ax-Crazy if he even thinks you mentioned that he was poor. Though just as he is about to cut Morty, he claims his family is rich.
- Literally Shattered Lives: Thanks to being frozen then shuffled around, one of his feet cracks and he ends up in pieces.
- We Hardly Knew Ye: He's frozen about 20 seconds into his first appearance. 50 seconds later, he's shattered. It's possible that the universe Rick and Morty jump to in Rick Potion #9 has a still living Frank Palicky, but he's never been seen or referenced. Thus it's likely that the Frank of this dimension suffered a similar fate.
Yet another boy that Summer obsesses over.
- Ink-Suit Actor: He looks like a slightly younger version of his voice actor.
A girl from Morty and Summer's high school that Summer's ex Ethan dumps her for.
- Buxom Is Better: It's suggested more than once that Ethan dumped Summer for Tricia because the latter has big breasts.
- Casual Kink: She mentions enjoying getting peed on.
- Dangerously Short Skirt: Wears a red miniskirt that barely reaches past her hips.
- Parental Issues: She runs to call her mom after seeing the mutated Beth and Summer resolve their issues, suggesting Tricia has some sort of conflict with her own mother.
- Yaoi Fan Girl: We overhear her talking about how docking is a beautiful expression of love.
- Zettai Ryouiki: Wears light blue Grade A thigh length socks.
