The Candy Kingdom

Advertisement:
    Starchie 
https://static.tvtropes.org/pmwiki/pub/images/Starchy_6027.PNG
Voiced by: Tom Kenny

An inhabitant of the Candy Kingdom, distinguished by his hat, mustache, and the fact that he's a ball of starch. Starchie works as a gravedigger and runs his own late-night radio talk show.


  • Butt-Monkey: Bad things tend to happen to him, like getting thrown in the dungeon, attacked by zombies, or getting Freezer Burn Flu.
  • Conspiracy Theorist: He takes calls from them on his radio show.
  • The Cuckoolander Was Right: Turns out he was right about PB being replaced by a lizard imposter in "We Fixed A Truck".
  • Faking the Dead: Faked his death and ran away to get away from Princess Bubblegum's intrusive surveillance. She then had him cloned.
  • Felony Misdemeanor: Being thrown in the dungeon for three hours by the Earl of Lemongrab. Starchie doubted he would even survive that long.
  • Gasshole: Squeeze him and he'll fart.
  • Gone Horribly Right: The Ice King's pained howls free him from the Freezer Burn Flu, and after saying he feels healthy again, he immediately bulks up even more.
    Starchie's feeling healthy again. [Bulks up further] A bit too healthy if you ask me.
  • I'm a Humanitarian: He can't help it. Flesh is delicious.
  • Living Polyhedron: As you'd expect from a living tapioca pearl.
  • Nice Hat: One of his distinguishing features.
  • Third-Person Person: Always seems to refer to himself in the third person:
    [Upon being sent to the dungeon] If Starchie lives that long.
  • Took a Level in Jerkass: While original Starchie was a kindly old man, his clone is a jerk.

    Mr. Cupcake 
https://static.tvtropes.org/pmwiki/pub/images/150px-mrcupcake_6537.png

The strongman of the Candy Kingdom, Mr. Cupcake is, as his name suggests, a giant cupcake.


  • Badass Mustache: He sports a handlebar one.
  • Feel No Pain: In an attempt to avoid going and living with Lemongrab for a few weeks so he wouldn't be so lonely, Mr. Cupcake broke his own arm. The only sound he made during the whole thing was a single grunt, which sounded more from effort.
  • Naked People Are Funny: In "Slumber Party Panic", while playing Truth or Dare, Chocoberry dares him to take off his wrapper.
  • Sesquipedalian Loquaciousness: Very well spoken.
    Mr. Cupcake: "Surely this frosted drink will soothe my fevered tempers." [Drinks milk shake when he hears Hug Wolf Finn] "Hello? Good heavens! A lycanthrope!"
  • World's Strongest Man: He's supposedly the strongest of all the candy people.

    Manfried

Click here  to see Aunt Lolly.

Voiced by: Maria Bamford

A talking pinata, Manfried serves as a PA for the Candy Kingdom.


  • Bearer of Bad News: Usually this for Princess Bubblegum.
  • Big "WHAT?!": In "Slumber Party Panic", upon hearing that they were going to smash pinatas. Finn quickly reassured him that he wasn't going to be smashed.
  • Cool Horse: Or in this case, a cool pinata.
  • Samus Is a Girl: In a flashback episode, it was revealed that the male pinata, Manfred, was actually PB's Aunt Lolly.
  • Was Once a Man: Was previously PB's Aunt Lolly, turned into a pinata by Uncle Gumbald.

    Banana Guards 
https://static.tvtropes.org/pmwiki/pub/images/125px-banan_guard_1400.png
Voiced by: Pendleton Ward

The Royal Guard of the Candy Kingdom, serving as both police and bodyguards to Princess Bubblegum.


  • Human Shield: They literally use themselves as barricades in "Princess Cookie". Though maybe it's more "Banana guard" shield.
  • Nothing Exciting Ever Happens Here: In "You Made Me", they didn't tell Princess Bubblegum about Lemongrab sneaking into Candy People's rooms because it would take away their "weird TV show", which they wanted to keep because, in their words, "Banana Guarding is boring".
  • Obfuscating Stupidity: As revealed in "The Thin Yellow Line", many of them have talents that they hide out of fear of Princess Bubblegum.
  • Police are Useless: They rarely manage to acomplish their job protecting the kingdom. Princess Bubblegum is so dissapointed by it that she assigns Root Beer Guy in charge of the Banana Guard.
  • Praetorian Guard: For Princess Bubblegum.
  • You Are Number 6: In "The Thin Yellow Line", Finn meets one called Banana Guard 16, implying that the others are numbered as well.

    Gumball Guardians 
https://static.tvtropes.org/pmwiki/pub/images/100px-gumball_guardian_1890.png
Voiced by: Tom Kenny & Steve Little

A pair of giant Candy People with gumball machine heads. Initially presumed to be statues, they sit at opposite ends of the kingdom blowing bubbles. They only act in the utmost circumstances, such as The Lich going on a rampage in the city. They are also the Guardians of the Royal Promise, punishing those who break Royal Promises. They were built by Princess Bubblegum during the early days of the candy Kingdom as a way to defend the candy people from the bath gang and were responsible for the death of Shoko.


  • And I Must Scream:
    • "Mortal Recoil" reveals that they retain some sentience if their heads are smashed, but are unable to move their bodies.
    • The one that is assimilated by GOLB's monster begs to be saved as he slowly turns into a Lich-like being.
  • Cruel and Unusual Death: In the finale, one of them gets corrupted by Golb and has only enough time to beg for help before turning into a grotesque monster. He is then vaporized when Betty puts a stop to Golb's actions.
  • Demonic Possession: By Little Dude in the titular episode and as a result of Golb's corruption in "Come Along With Me".
  • Eye Scream: Marceline gouges one of his eyes after he is corrupted by GOLB. It doesn't do much in the long run, as by this point the Guardian had developed a Healing Factor.
  • Felony Misdemeanor: When Princess Bubblegum pleads for Finn, they decide to give him a less hot trial: Math questions.
  • Kill It with Fire: Their initial punishment for breaking a Royal Promise is to subject the promise-breaker to Trial by Fire.
  • Time Stands Still: They do this when you break a Royal Promise, causing everyone but the promise breaker and the one who demanded the promise to freeze solid.
  • Wave Motion Gun: Have a rather... impressive weapon that has only been seen once while being piloted by Finn's mind-control hat.
  • The Worf Effect:
    • If anything is strong or evil enough to get their attention (Like The Lich, or Gunther), they get beaten fairly quickly. Subverted on occasion, as they do most of the work when the Oozers invade the Candy Kingdom.
    • In the finale both of them die rather gruesome deaths, with one of them being converted into a gigantic Lich-like creature before Betty erases him.
  • Your Head Asplode:
    • They suffer this when Finn gets the math question right.
    • The most common way to incapacitate them.

    Royal Tart Toter 
https://static.tvtropes.org/pmwiki/pub/images/250px-toter_109.png
Voiced by: Stephen Root

The Guardian of the Royal Tarts, the only Candy Kingdom food worth killing for. He protected the Royal Tarts when they were escorted to the Annual Back Rubbing Ceremony, until he became senile and unable to discharge his duties. Sadly, his mental state has left him unaware of that, and he still believes he's carrying the Royal Tarts.


  • Badass Mustache: Subverted, it was once badass, but then it got torn.
  • MacGuffin Guardian: His job was to guard the Royal Tarts in their journey from the Candy Kingdom to the Sacred Backrubbing Ceremony.
  • The Mentally Disturbed: He is senile and schizophrenic.
  • Mind Screw: The infamous "Tart Toter speech":
    Royal Tart Toter: This cosmic dance of bursting decadence and withheld permissions twists all our arms collectively, but... if sweetness can win—and it can—then I'll still be here tomorrow to high-five you yesterday, my friend. Peace.
  • Serious Business: Guarding the Royal Tarts was. In the title card of "The Other Tarts" shows him having to fight off several people trying to grab the Tarts.

    Stormo 
https://static.tvtropes.org/pmwiki/pub/images/200px-stormo_2_9323.png
Voiced by: Henry Linehan

Yet another experiment, made to counter Goliad using Finn's hair as a base. Stormo quickly proves true to his heroic roots and traps Goliad and himself for all eternity, to save the Candy Kingdom.


  • Big Damn Heroes: See Dynamic Entry.
  • Body Horror: The third eye, which works the same as Goliad's.
  • Cain and Abel: Abel to Goliad's Cain.
  • Dynamic Entry: He rushes in just in time to save Finn and the Candy Kingdom from Goliad.
  • Good Counterpart: Based on Finn's DNA rather than Bubblegum's.
  • Heroic Sacrifice: Locks himself and Goliad in an eternally stale-mated psychic battle. Truly impressive in that he doesn't even hesitate to do so.
  • Like Father, Like Son: In a way, he is Finn’s son, being made from his DNA. So just like Finn, Stormo is every bit as noble and heroic. He also inherits Finn’s blonde hair.
  • Psychic Powers: With the power of his third eye, he can manipulate objects and other beings, just like Goliad.
  • Sibling Yin-Yang: It's unclear to what extent they are siblings, but they're as different as night and day. The addition of Finn's DNA into Stormo's primordial goop is the only noted difference between them.
  • Telepathy: See Psychic Powers.
  • The Unintelligible: Speaks entirely in birdlike screeching sounds, though Goliad seems to understand what he's saying.

    Princess Cookie 
https://static.tvtropes.org/pmwiki/pub/images/250px-princess_cookie_8206.png
Voiced by: Donald Faison

A chocolate chip cookie orphan who wanted to grow up to be a princess, so as to spread love and joy. But Princess Bubblegum laughed when she heard this, because he's really a dude named Baby-Snaps. Eventually grew up and held a convenience store full of candy people hostage. Currently resides in a candy people mental institute.


    Braco 
https://static.tvtropes.org/pmwiki/pub/images/200px-braco_5785.jpg
Voiced by: Johnny Pemberton

One of Princess Bubblegums many suitors, Braco is the the third generation of his family to become a suitor after his father ascended. At the age of twenty one he was the yougest suitor by far, with the oldest being over three-hundred. He looks like a normal human except for his skin color and the crystal like candy on his head. His whole personality revolves around his intense infatuation with Bubblegum.


  • Ambiguously Human: Looks like a normal human except for skin color and sugar crystals in his head.
  • Body Horror: Ogdoads spell makes him into a hidious monster, but see below...
  • Deal with the Devil: With the shadow creature Ogdoad
  • Dogged Nice Guy: Deconstructed. His efforts are expressly against the princess's wishes and bring him nothing but pain.
  • Even the Guys Want Him: The effects of Ogdoads spell causes everyone to love him.
  • Too Dumb to Live: Every bad thing that happens to him physically is because he is so infatuated with Bubblegum that he doesn't think things through; which includes jumping into a fire pit and accepting Ogdoad's offer despite the demons warning.

    Root Beer Guy 
https://static.tvtropes.org/pmwiki/pub/images/100px-root_beer_float_8455.png
Voiced by: Jack Pendarvis

A background character who ends up the focus of the episode "Root Beer Guy". A Candy Kingdom telemarketer and wannabe mystery writer, he spies Finn and Jake kidnapping the princess once night and investigates the case despite the concerns of his wife, Cherry Cream Soda. As it turns out, the kidnapping was all staged to test the Banana Guards, who not only horribly failed the case, but had Root Beer Guy handcuffed. As a result, Root Beer Guy was promoted to the head of the Banana Guards.

    Cherry Cream Soda 
https://static.tvtropes.org/pmwiki/pub/images/cherry_cream_soda.jpg
Voiced by: Anne Heche

An attorney as well as the wife of Root Beer Guy.


    Rattleballs 
https://static.tvtropes.org/pmwiki/pub/images/1390578008000-rattle_1836.jpg
Voiced by: Rainn Wilson

A robotic gumball machine and a mysterious, masterful swordsman who lives out in a junkyard. He far surpasses Finn and the blade of grass by skill alone in their first fight. Though reluctant to train Finn at first, he agrees after Finn does him a long needed favor. He then reveals to Finn that he is the last of an elite force of gumball machine police-bots that Princess Bubblegum massacred a long time ago following a mass lapse in their discipline. When Finn reveals his existence to Bubblegum, she sends a squad to the junkyard to ambush Rattleballs. He incapacitates all of them but leaves them alive, and after thus proving his skill and re-pledging his loyalty to Bubblegum, she hires him as a vigilant watch over the night in the Candy Kingdom.


  • Really 700 Years Old: He was built a while after the radioactive river from "Shoko" was gone, but when Bubblegum created him, the Candy Kingdom still wasn't finished and the Banana Guards were still green.
  • "Second Law" My Ass!: He had to use all of his willpower to turn away from the wall, look at the massacre, and escape. This is a rare instance when the trope is given to a good-aligned robot who isn't an anti heroic jerkass.
  • Sliding Scale of Robot Intelligence: Probably a Grade 3, but he makes up for it as a Badass Normal.
  • Technical Pacifist: When Bubblegum thinks he's slain her entire ambush squad, the squad is revealed to be bruised but alive, thus demonstrating both his skill and his self-control.
  • Three-Laws Compliant: He interprets the First Law loosely (see Technical Pacifist, above), plays the Third Law straight while the rest of his kind walk straight to the crusher, but...

    James 
https://static.tvtropes.org/pmwiki/pub/images/4652744cbcaf4fd1cd83ff030a66c361.png
Voiced by: Andy Merrill

A Candy Person who accompanies Finn, Jake and Bubblegum on a mission.


  • Chronic Hero Syndrome: He is more than willing to sacrifice himself to save Princess Bubblegum. Even if she's not actually in danger.
  • Cloud Cuckoo Lander: His behavior is... strange, to say the least.
  • Cloning Blues: Princess Bubblegum clones him every time he dies.
  • The Exile: PB makes him leave the Candy Kingdom after the events of "James II." No one will miss him.
  • Faking the Dead: He fakes his death twenty-five times to get medals.
  • Fusion Dance: All of the clones fuse into one being at the end of "James II".
  • Glory Hound: He fakes his death just to collect medals.
  • Heroic Sacrifice: He lets himself be killed by the Ooze Monsters so that PB, Finn, and Jake can get away.
  • I Just Want to Have Friends: The original reason that he starts faking his death- so that Bubblegum will clone him and he'll have a new friend to hang out with. After that, it just becomes about the medals.
  • They Killed Kenny Again: He's died defending Bubblegum at least twenty-five times. Or so it seems.
  • What Measure Is a Non-Human?: Bubblegum lets him sacrifice himself rather than let Finn do it, because he's made of candy and can be easily cloned, while Finn can't.

    Colonel Candy Corn 
https://static.tvtropes.org/pmwiki/pub/images/f011265bc3ec2751980029e8ef449cd6.png
Voiced by: Keith Ferguson

A retired officer in the Candy Kingdom military. Commands the Banana Guards after Root Beer Guy's death.


  • Badass Mustache: He's an officer with a mustache.
  • Colonel Badass: Battles Darren's monster soldiers with a saber.
  • Da Chief: Of the Banana Guards, after Root Beer Guy's death.
  • The Generalissimo: Declares a military dictatorship in the Candy Kingdom when Princess Bubblegum is feared dead.
  • May–December Romance: He's looking for one of these, hoping for a "young woman with an old soul".

    Crunchy 
https://static.tvtropes.org/pmwiki/pub/images/crunchy_adventure_time.png
Click here  to see Chicle.

Voiced by: Tom Kenny
A candy person.
  • Accidental Hero: He kills the Hierophant, an extremely dangerous vampire, by bumping into him.
  • Back from the Dead: He explodes in fear in "Something Big", but a title card at the end reveals that he got put back together.
  • The Dog Bites Back: He knocks the King of Ooo into a fireplace and melts him when he tires of the King's abuse.
  • Hunting the Most Dangerous Game: The King of Ooo hunts him for sport during his reign as princess.
  • The Starscream: Under Colonel Candy Corn's brief dictatorship.
  • The Usurper: Twice. First from Colonel Candy Corn when Princess Bubblegum briefly disappears, and then from the King of Ooo when the Candy People turn against him. Later we find out he was one of the first candy people, who planned to betray Bubblegum, but became what he was today when Gumbald betrayed him first.
  • Vocal Dissonance: His voice is impressively deep and scratchy given his appearance.
  • Was Once a Man: Used to be another fully intelligent bubblegum person, PB's "cousin" Chicle, but was turned into a candy person by Uncle Gumbald.

    Neddy 
https://static.tvtropes.org/pmwiki/pub/images/adventure_time_neddy.png
Voiced by: Andres Salaff

A candy dragon who lives in the depths of the Candy Kingdom, suckling on the roots of the candy tree and secreting candy juice that the rest of the Candy Kingdom uses for bathing and healing. He's also Princess Bubblegum's brother.


  • Ambiguous Disorder: Despite being a huge candy dragon, Neddy is reclusive and has a crippling fear of anyone and anything who isn't his sister Princess Bubblegum. Apparently, this is the result of his first experience when being "born" was landing painfully on a sharp rock, presumably associating the outside world with danger and pain. PB is well aware of how different Neddy is from most people:
    Princess Bubblegum: People are built different. We don't need to figure it out, we just need to respect it. Maybe he likes his own company better than I like mine.
  • Blob Monster: Like his sister, he was originally part of a massive wad of gum that PB refers to as "the Mother Gum". He and PB eventually broke away from it and became their own separate beings. Neddy looked quite a lot like a blob even after breaking away from the Mother Gum, and he somehow evolved to look like a dragon.
  • Immortal Immaturity: He's a little younger than Bonnie, but acts very much like a very young frightened child. His sister keeping him in isolation probably contributed to it. He's very fearful of the outside world and is only happy when sucking on the roots of candy trees and being with Bonnie relaxes him.
  • Madwoman in the Attic: Played With; Princess Bubblegum keeps him hidden away, not because she's embarrassed of him, but to keep him safe since he's so sensitive and so terrified of everyone and everything. He really just wants to be left alone to suck on the candy tree roots, which lets him provide the Candy Kingdom with precious candy juice to keep them healthy and clean. Despite this, there was a rumor among the Banana Guards that PB kept him chained up (though this further implies that Neddy's existence isn't even secret). Apparently, PB's artificial family she made was aware of Neddy and she made them in order to have someone like her to talk to, implying she was a bit overwhelmed when dealing with him when she was younger. Nonetheless, she still loved him and got pissed when Gumbald threatened him.
  • Our Dragons Are Different: He's huge and made of gum, for one thing. He also has tiny wings, his head is upside down, and he secretes precious candy juice by suckling on the roots of the candy tree.
  • Powered by a Forsaken Child: The whole kingdom runs on the juices he secretes. He's not really forsaken as much as hiding from the outside world due to being afraid of basically everything that isn't Princess Bubblegum.
  • Really 700 Years Old: Like PB, he's around 827 years old since he was "born" shortly after she was. Not that you could tell at first glance, since he acts like a frightened child most of the time.
  • The Speechless: He never actually speaks and can only make various sounds (usually crying or screaming in terror).

The Lemongrab Earldom

    Lemongrab 2 

Lemongrab 2

https://static.tvtropes.org/pmwiki/pub/images/lemongrab_2_in_clothes_with_septer_1126.png
Voiced by: Justin Roiland

Lemongrab's clone. Created by Princess Bubblegum for the purpose of giving Lemongrab a companion.


  • Cloning Blues: Lemongrab 2 was created to be a companion to the first one, and, despite their obnoxious personalities, are actually both very happy together with their family until "Too Old".
  • Color-Coded Characters: To differentiate between him and Lemongrab, one wears grey and the other wears white.
  • Defector from Decadence: Lemongrab 2 in "Too Old" is rebelling against Lemongrab 1.
  • Divergent Character Evolution: At first, Lemongrab and Lemongrab 2 are essentially the same in every way. In "Too Old" they're shown to have become different, but with disastrous consequences: though Lemongrab 2 has become nicer and learned the error of his ways, Lemongrab has taken major levels in cruelty and insanity.
  • Good Parents: As evidenced in "All Your Fault" (despite him not really thinking through the situation he and his brother were creating for their new family, not just themselves), "Another Five Short Graybles", and especially Too Old, Lemongrab 2 is a loving father to his many children, starkly contrasting the direction Lemongrab 1 wound up going. This is most clearly (and depressingly) demonstrated when he shares his food with one of his children, who'd just had his taken away, despite clearly being starved and sickly himself.
  • Hair-Trigger Temper: Though downplayed compared to his clone. In "Too Old" it's nearly nonexistent, presumably because he's very, very weak from hunger and from being sick.
  • Handicapped Badass: He later suffers from the loss of his legs, most of his health, and half of his head. That doesn't stop him from being a hero and a martyr for the cause of the lemon people.
    • Well, he would have been a martyr, if he didn't survive inside of his brother's stomach.
  • Heroic Sacrifice: He takes away Lemograb's ear plugs and tells Lemonhope to keep playing, even when he knows that this will result in his own death.
  • Jerk with a Heart of Gold: In his earliest appearances, he comes across as being mildly annoying, but unlike the original Lemongrab, that's the only problem he appears to have, and he still did things like immediately suggest to pardon the prisoners after meeting and bonding with his brother. The "jerk" part seems nonexistent by the time of "Too Old", as he's nothing but nice and generous throughout the entire episode, and in "Lemonhope Story", he commits a Heroic Sacrifice for his children's sake.
  • Killed Off for Real: Subverted. After Too Old, he survives inside Lemongrab's stomach. Subverted again when he actually dies when his brother explodes, but Bubblegum integrates the remains of both Lemongrabs into a single Lemongrab at the end. Being merged with his brother allowed him (Lemongrab 1) to have much more empathy, eventually pushing him into Heel–Face Turn territory.
  • Morality Pet: Formally to Lemongrab. Grossly averted in "Too Old."
  • Naked on Arrival: The first time we see Lemongrab 2, he's butt naked.
  • Only Sane Man: Well, compared to his clone in "Too Old", anyway. It's a fact that almost all of the lemon people (with the exception of Lemonhope) are totally nuts. The difference between Lemongrab 2 and Lemongrab is that Lemongrab 2 is very kind while his brother is not. Lemongrab 2 is definitely crazy, but not violent or a bad person.
  • Took a Level in Kindness: He was never a bad guy, but he was something of an intolerable, annoying prick, just like Lemongrab. He eventually stopped being quite as annoying, and became genuinely polite and friendly, even selfless.
  • Vocal Evolution: Over time his voice has gotten less cacophonic, and his speech styles more coherent and eloquent, such that by the time of Lemonhope Part 2 it's lost most of the jarring qualities that simultaneously became more exaggerated in Lemongrab 1. It emphasizes his character evolution into Only Sane Man and selfless Papa Wolf.

    Lemonjon 

Lemonjon

https://static.tvtropes.org/pmwiki/pub/images/250px-vlcsnap-2013-01-30-03h31m47s187_5460.png
Voiced by: Justin Roiland

The eldest of the Lemongrabs's children. A lemon giant with a booming voice, he proves himself early on to be more sensible, and helpful, than his fathers. He even sacrifices his own life to protect his family and all of the Candy People. In the words of Finn, Lemonjon is "all right."


  • Ambiguous Disorder: He's awkward, has difficulty in processing and articulating his emotions, and has an unconventional manner of speaking. There's also the fact that he had a rather serious case of cardiac arrest, which was only resolved when Finn and Jake punched his heart.
  • Cloud Cuckoolander: Not to the same extent as the earls, but he is a pretty strange dude.
  • Dark Is Not Evil: His appearance is disturbing and he's pretty damn ugly, but he's a downright wonderful guy.
  • Final Speech: Gives a beautiful, eloquent, and heartbreaking one just before he dies.
    Lemonjon: Whoa, hold the phone! What is this powerful new juice coursing thrumpst my core source? The juice aches. Is this the rumored ache of feeling? The feeling of caring unknown to lemons? New thoughts emerge... If I act, the candy people will suffer; if I don't, the lemon people will suffer! The greater good demands but one course only! That I dissolve the bonds uniting me and become component to all!
  • First Time Feeling: "Is this the rumored ache of feeling? The feeling of caring unknown to lemons?"
  • Funny Afro: The lighter-colored, fluffy lemon candy piled atop his head gives him this appearance. It resembles a big perm divided into three slightly spiked-up sections.
  • Gag Nose: He has two. Why the Lemongrabs thought it was essential that Lemonjon have two noses has not been explained.
  • Gentle Giant: Absolutely. He's one of the largest Candy People ever to exist, and he's also perhaps the most selfless.
  • The Giant: He's as big as the whole castle, and is the castle, kind of.
  • Giant Mook: The Lemongrabs attempted to use him as this.
  • Heart Trauma: Finn and Jake punch his heart to attempt to kill him. Instead, this causes his heart to start beating, resulting in Lemonjon having an epiphany.
  • Heel–Face Turn: While he was never a villain, he seemed neutral, yet still willing to attack the Candy Kingdom. But he eventually Took a Third Option which resulted in his own death.
  • Heroic Sacrifice: To save his family and the Candy People.
  • Killed Off for Real: The second important character to suffer the fate of permanent death- the first was Billy.
  • Large Ham: " Mmmmmm... MENAGERIE! "
  • Like Father, Like Son: "Three weeks dungeon." He seems to have inherited the pedantic speech of his fathers.
  • Literal Change of Heart: His heart actually awakens when Finn and Jake punch it.
  • Living Structure Monster: He's so big he takes up the whole castle, and is essentially part of it.
  • Moral Dilemma: "If I act, the Candy People will suffer! If I don't, the lemon people will suffer!" He eventually takes a third option that saves everyone's lives but his own.
  • The Needs of the Many: His reasoning for his Heroic Sacrifice.
  • No Indoor Voice: In a different way than the Lemongrabs. While the Lemongrabs are very shouty, Lemonjon tends to speak much more calmly, and doesn't yell. But Lemonjon is very loud, because he's a literal giant. He can't really help it.
  • Take a Third Option: He explodes and reverts to lemon candy to feed his starving family rather than attack the Candy Kingdom to steal their food.
  • Telepathy: He seems to have this ability. When Finn and Jake asked him about the location of the earls, Lemonjon closed his eyes, and said in a strained voice that he "sensed" that they were in the dungeon.
  • Too Good for This Sinful Earth: "Man... That Lemonjon was all right."
  • Tortured Monster: Although the Lemongrabs view him as a child, they did attempt to use him as a weapon. And when he's slowly standing up, after months of literally being attached to the ground, he sounds like he's in pain.
  • Wacky Parent, Serious Child: He seems much more down-to-earth and reasonable than his dads.
  • What Is This Feeling?: Mentions this trope in his final speech.
  • Younger Than He Looks: He's a giant and he has a low, booming voice. But the Lemongrabs say that Lemonjon is "young," and only a child. Which makes his untimely and sudden death all the more heartbreaking.

    Lemon Children 

Lemon Children

https://static.tvtropes.org/pmwiki/pub/images/320px-lemon_children_2-1_5510.jpg
Voiced by: Justin Roiland

The strange-looking and eccentric, toddler-aged children of the Lemongrabs. They reside in Lemon Castle, and there seem to be dozens of the little pooters.


  • Affectionate Nickname: According to the screenshot of Lemongrab’s brain, the earls affectionately call their babies “little pooters.”
  • Amazing Technicolor Wildlife: The Lemon Children are a strange combination of person, plant, animal, and fungi- and they’re all various shades of yellow, orange, and green.
  • Ambiguous Disorder: They all seem pretty “off,” but it hasn’t been made clear if they’re as bonkers as their dads yet.
  • Babies Make Everything Better: According to the Lemongrabs.
  • Baby Talk: The only word we could hear them say was “hungry” and "candy." For the most part, they just babble and shriek.
  • Body Horror: Some of the Lemon Children are rather grotesque- limbless, disfigured faces, lumpy and misshapen.
  • Carnivore Confusion: When they are starving, they attempt to eat Finn and Jake. However, it strangely never occurs to them to eat each other, even though they are all mostly made of candy themselves.
  • Children Are Innocent: Toyed with. They seem to mostly be toddlers, but they’re enthusiastic about their dads’ plan to take over the Candy Kingdom.
  • Cloud Cuckoolander: Obviously, given who their progenitors are.
  • Conjoined Twins: Some of them.
  • Creepy Child: Finn and Jake seem to think this about some of the Lemon Children, especially the one whose face pealed back.
  • Cute, but Cacophonic: Many of the Lemon Children are rather adorable in appearance, but they have high-pitched, shrieking voices.
  • Dysfunctional Family: Let's just say, they're about as functional as the Griffins if they were all three times as insane, and lemons.
  • Eyeless Face: Some of them don't have eyes or faces. In fact, some of them are just lemons with wings attached.
  • Gag Nose: Several of them have the long, pointy noses of their dads. Others have big, bulbous noses.
  • Gonk: Some of the Lemon Children could be considered to be quite ugly.
  • Green Eyes: The Lemon Child with the pealing face has green eyes.
  • Grotesque Gallery: They're all twisted and lumpy.
  • Has Two Daddies: They are Lemongrab and Lemongrab 2's children, but regardless, they're a big happy family.
  • It Runs in the Family: Some of them seem pretty “special.”
  • Last-Minute Baby Naming: The earls seem to name their children at the last minute. Seconds after they brought the candy seeds to life, Lemongrab jubilantly yelled, “Ha-HA! We’ll call you SEED-WAD!”
    • The earls still haven’t decided whether their second-youngest child is named “Plop-Top” or “Dump-Dome.”
  • Let's Have Another Baby: The earls probably said this to each other at some point, and it just kept happening, over and over again…
  • Like Father, Like Son: Many of them have the same eyes as their fathers, and many of them resemble lemons in some way.
  • Massive Numbered Siblings: Well... there are over twenty of them.
  • Nice Shoes: The multi-mouthed lemon child has a pair of little hot pink cowboy boots.
  • Nipple and Dimed: Several of the Lemon Children have nipples and visible breasts (due to being chubby babies.)
  • No Indoor Voice: Possibly due to being children, possibly due to being the sons of the Lemongrabs. In one scene, Plop-Top, who had been sitting calmly the whole time, randomly opens his mouth to emit a high-pitched, piercing shriek. He then resumes looking calm.
  • One-Gender Race: According to the Lemongrabs, all of their children are male.
  • Petting Zoo People: They range from being strange-looking people to being anthropomorphic to looking like actual animals.
  • Pint-Sized Kid: Some of them.
  • Plant Person: Some of the Lemon Children resemble plants or mushrooms.
  • Royally Screwed Up: Assuming the Lemongrabs are brothers.
  • Shared Family Quirks: Their tendency to scream at random intervals. Apparently, the earls view the screams of their children as “piercing songs.”
  • The Scream: They take after their fathers in this department. Seems to be a lemon trait.
  • That Thing Is Not My Child!: Adorably averted. Many of the Lemon Children are downright grotesque-looking and deformed, but the earls love every single one of them and treat them all like their babies.
  • Too Many Babies: Or in this case, way too many.
  • The Unintelligible: Because of their age, they can only communicate using one-word or monosyllabic sentences, strange noises, and shrieks.
  • Vocal Dissonance: Most of them sound like how one would imagine the children of the Lemongrabs sounding- high, shrieky voices. But the tiny Lemon Child with the pealing face has a very low voice, which he uses to bellow continuously.
    • Averted when said child appears later on and he has a high, squeaky voice.
  • Vomit Indiscretion Shot: Seed-Wad barfs all over himself after the Lemongrabs make him.
  • Wave of Babies: The Lemon Children all mob Finn and Jake in a large herd, rubbing against them and attempting to chomp on them.
  • What Measure Is a Non-Cute?: Invoked when one of the Lemongrabs' babies literally turns out to be a vomiting pile of colorful mush. They act like this child is the most precious and wonderful creature they’ve ever seen. Played pretty straight when the only lemon child the Princess shows any interest in is Lemonhope, who's the least Ugly Cute and strange of all them.

    Lemonhope 

Lemonhope

https://static.tvtropes.org/pmwiki/pub/images/adventure_time_lemonhope.png
Voiced by: Justin Roiland

One of the lemon children, who is the least disfigured of his siblings and is musically gifted, which makes Princess Bubblegum take interest in him and decide to take him to the Candy Kingdom against Lemongrab's wishes. He is, however, freed by Lemongrab 2 and the rest of the lemon children, believing he can one day return and free them from Lemongrab's reign.


  • Book Dumb: Princess Bubblegum tries to give him an education, but it doesn't leave much of an impression on him and he later admits that he faked learning how to read. Phlannel Boxingday remarks that Lemonhope learns with his heart, not with his head.
  • The Call Knows Where You Live: His attempts to run away from his debt to the Lemon People, failed because of his guilty conscience.
  • A Day in the Limelight: Has his own two-part episode.
  • Foil: For Finn. They're both the same age more or less, and they're both seen as champions for their kingdom. But while Finn happily lives up to the challenge, Lemonhope is like a lot of kids in that he wants to be on his own and only did the right thing once because he felt guilty.
  • Has Two Daddies: Personality-wise, he's inherited traits from both.
  • I Just Want to Be Free: His reason for leaving the Candy Kingdom and not staying to rule Lemon Castle after defeating Lemongrab. Makes sense since he spend most of his life locked in a bathroom.
  • It's All About Me: Played with. Lemonhope wants nothing more than freedom, even if it means going his own way and leaving his family to suffer under the hand of his abusive father. On the other hand, he also recognizes that freedom entitles others to do whatever they choose, even if it isn't to his benefit.
  • Leitmotif: Poor little Lemonhope...Sweet little Lemonhope
  • Meaningful Name: He is believed by all the Lemon Children and Lemongrab 2 to one day bring hope to all of them.
  • Messianic Archetype: For the Lemongrab Earldom.
  • Only Known by Their Nickname: His given name is "BadLemonNoHope", but prefers "Lemonhope" and is only called that by Lemongrab.
  • Only Sane Man: Compared to all the other lemon people (with the exception of Lemongrab 2) who are totally nuts, which is part of the reason Princess Bubblegum shows any interest in him.
  • Sociopathic Hero: While not really a bad guy, Lemonhope is primarily driven by his desire to be free to fulfill his own wants. Only when his subconscious guilt sours that freedom is he driven to help the people he owes his happiness to, specifically to be free of his debt to them.
  • Shared Family Quirks: When Lemonhope yells at Phlannel Boxingday to stop his ship (thinking he's seeing his siblings coming out of a monster's mouth), it devolves into one of Lemongrab's signature screams.
  • The Unfavorite: Out of all their children, Lemonhope is Lemongrab's least favorite, to the point that he's kept locked in a bathroom.
  • Ungrateful Bastard: Doesn't show concern with how Lemongrab is treating all his siblings as punishment for helping him escape.
  • Walking the Earth: Does this for the next thousand years after freeing Castle Lemongrab.

The Flame Kingdom

    Flambo 

Flambo

https://static.tvtropes.org/pmwiki/pub/images/Flambo_5707.png
Voiced by: Tom Kenny

A mischevious creature who is an informant and ally of Finn and Jake. He is a flambit, a type of fire-creature that resembles a cat made of flame, but is so far the only flambit shown to be able to speak and use magic. He works for lumps of coal, which he eats.


  • And Your Reward Is Edible: Characters are shown feeding him charcoal as payment for his services.
  • Baleful Polymorph: "Incendium" implies that he, and all flambits, were created from normal fire elementals by Flame Princess in one of her tantrums.
  • Exact Words: "I know just the skirt! And she's way hot!
  • The Gadfly: He intentionally obscures his intentions and withholds information in "Incendium" to force Jake to improvise, which he finds amusing.
    Flambo: There, I cast Flame Shield on ya's. Also I spat on ya's.
  • The Informant: He helps Finn and Jake keep tabs on the Ice King.
  • Instant Runes: When casting.
  • Kill It with Water: In the video game Flambo's Hot Mess.
  • Mundane Utility: Finn uses Flambo to light his flamethrower in "Business Time," and Princess Bubblegum uses him to light the grill for her Science BBQ in "The Real You."
  • My Species Doth Protest Too Much: Flambo's fairly nice if mercenary, but supposedly everyone in the Fire Kingdom is evil.
  • Playing with Fire: It may just be an extension of his natural body, but Flambo can keep things warm and set them on fire.
  • Put on a Bus: Andy Ristaino has stated that Flambo is hard to get ahold of, explaining why he's not usually around to cast Flame Shield on Finn for his dates with Flame Princess.
  • Screams Like a Little Girl: Lampshades this himself after Jake rescues him in "Incendium."
    Flambo: Bet you thought I was a dame on account of my girlish screamin'.
    Jake: (frustrated) I did think that.
  • Status Buff: The only magic ability he's shown so far was Flame Shield, which protects mortals from fire.
  • Unexplained Accent: He may not be from the Bronx, but his accent sure is.

    Flame King 

Flame King

https://static.tvtropes.org/pmwiki/pub/images/flame_king_profile_image_2770.png
Voiced by: Keith David

The former ruler of the Fire Kingdom and father of Flame Princess. He is evil, like everyone in the Fire Kingdom.


  • Abusive Dad: Sure, locking his daughter in a lantern for her entire life wasn't a terribly nice thing to do, but considering how powerful and destructive she is, he had a good reason... but then Earth and Water reveals that the lantern was actually Plan B. His first idea upon learning how powerful she was as a baby was to leave the newly born Flame Princess in the wilderness to die, not because he cared about the destruction she might cause, but because he was afraid she would usurp him.
  • Acrofatic: Subverted, it seems like it on the surface, but when you take into consideration that fire doesn't really have weight and the only thing holding him down is his armor it starts to make more sense.
  • Affably Evil: He's quite polite for an Evil Overlord.
  • Bad Boss: Was fine with "Finn" killing his court jester and in Playing With Fire he chastised his cook for dinner being ready 10 minutes early.
  • Cain and Abel: He extinguished his own brother to become King.
  • Card-Carrying Villain: He may not be of the diabolical Laughing Mad variety, but he's still pretty open about the fact that he's evil.
  • Even Evil Has Standards: Evil though he may be, apparently letting Flame Princess destroy the entire planet is a little too much for him, so he followed Princess Bubblegum's advice on locking her up. Later subverted since it turns out that he didn't really care about the destruction his daughter might cause; he only locked her in there so she wouldn't take his throne from him.
  • Evil Is Burning Hot: The Flame King, anyone?
  • Evil Overlord: He rules over the Flame Kingdom.
  • Evil Parents Want Good Kids: Inverted (sort of) since his definition of "good" is evil. So he sneaks into Flame Princess's house through her scented candle flames and starts whispering in her ear..
    Flame King: Evil. Evil evil evil. Evil evil evil evil!
  • Evil Sounds Deep: Comes with being voiced by Keith David.
  • For the Evulz: Playing With Fire shows him terrorizing the citizens of the Flame Kingdom just because he can.
  • Jerk with a Heart of Jerk: While he no longer acts hostile towards Flame Princess and even supports her during her rap battle in "Son of Rap Bear", he also refuses to apologize for how he mistreated her or even acknowledge any wrong doing on his part.
  • Klingon Promotion: He became the king by killing his older brother. Later on, he's on the receiving end of this trope when his daughter takes control.
  • Large and in Charge: He's a big dude, to say the least.
  • Orcus on His Throne: Just sits around in the Fire Kingdom, despite the rest of Ooo being inflammable and presumably ripe for conquest. Could apply to the Fire Kingdom people in general. On the other hand the rest of Ooo also contains a large amount of water, which has been shown to be fatal to Flame People, making a full scale invasion costly at best and suicidal at worst.
  • Sealed Evil in a Can: Usurped by his daughter and put inside the same lantern he put Flame Princess in.
  • Took a Level in Kindness: Sort of. While still a jerk, he at least attempts to support Flame Princess in "Son of Rap Bear" and no longer wants to dethrone Flame Princess; now content with peacefully ruling a chipmunk kingdom alongside Bun Bun.

Voiced by: Maria Bamford

Slime Princess' younger sister, who seeks to claim the royal throne as her own.


  • Beauty Is Bad: She is stated to be the most attractive woman in the Slime Kingdom. Played With, however, in the sense that her beauty has made the men in the kingdom too nervous to approach her, leading her to resort to some rather shady tactics in her quest for power.
  • Identical Twin ID Tag: Is only distinguishable from her sister by the fact that she wears a band with a green gem on her head as opposed to a tiara.

    "Oh hey Finn, I've got another Ice King situation here."
  • Planet of Hats: The Breakfast Kingdom, pretty much.

    The Duke of Nuts 

The Duke of Nuts

https://static.tvtropes.org/pmwiki/pub/images/120px-Prince-of-nuts_2379.png
Voiced by: Steve Little

The Duke of Nuts is a generally nice member of royalty, ruling over the Duchy of Nuts. An all-around family man, his only major flaw is that a physical deficiency makes him uncontrollably eat any pudding in range.


  • Adorkable: He's nice up to the point of being awkward. When he thanks Finn and Jake for waiting for him, he gives them daisy chain crowns as a token of his appreciation for waiting him.
  • The Bus Came Back: Returns in the Grand Finale as part of Princess Bubblegum's army.
  • Chuck Cunningham Syndrome: After the first season, he only made two appearances (one of them as a toy). Probably because he's just too nice a guy to be that interesting, and because Princess Bubblegum having an irrational and emotional grudge against him shows her to be flawed in a very different way to the one which they would later explore.
  • Happily Married: His wife quickly jumps to his defense in the pudding case. Also, he 'lies with her' often.
  • Nice Guy: Ridiculously nice. Almost obscenely nice. Hell, he was willing to take the fall for Finn even though he was totally innocent.
  • Poke the Poodle: About the only thing he's ever done wrong is eat all of Bubblegum's pudding.
  • Quirky Household: Him and his family are pretty weird, but love each other. His wife is nuts, in both the figurative and literal sense of the word.
  • Sitcom Arch-Nemesis: To Princess Bubblegum, who despises him solely because he ate all of her pudding once.
  • Sweet Tooth: He loves him some pudding.
  • Trademark Favorite Food: Pudding.

    The Duchess of Nuts 

The Duchess of Nuts

https://static.tvtropes.org/pmwiki/pub/images/duchess_of_nuts.png
"The nuts told me, for I am the Duchess of Nuts!"
The wife to the Duke of Nuts, and the matriarch of the Duchy of Nuts' royal family.
  • Ax-Crazy: While it can be partially chalked up to her concern for her husband, she still comes across as deeply unhinged during her conversation with Finn.
  • Maybe Magic, Maybe Mundane: She claims to be capable of communicating with her bowl of peanuts, but we are never given any sort of confirmation either way. Although if not, then that does raise the question of how, exactly she was aware of Finn and Jake's plan to arrest the Duke.

Voiced by: Maria Bamford

The princess of the Wildberry Kingdom.


  • Anthropomorphic Food: Looks like a berry.
  • Berserk Button: In "Furniture and Meat" we learn that, yes, you can push hers. Jake tries to pay her gold in exchange for getting to sit on her head. Her response? Confiscating all of Jake and Finn's gold, melting it down and planning to execute them by pouring it over them.
  • Beware the Nice Ones: Dear lord, don't let her timidness fool you. If she perceives herself as insulted, she will not take it well.note 
  • Distressed Damsel:
    • She is often seen being kidnapped by Ice King, much more frequently than most of other princesses than Princess Bubblegum, most likely because of her Fragile Flower nature.
    • In "Jake vs. Me-Mow," Wildberry Princess is the target of an assassin from the Guild of Assassins.
  • Planet of Hats: The Wildberry Kingdom: a kingdom where everyone is a berry.
  • Princesses Rule: Apparently the only ruler of the Wildberry Kingdom.
  • Shrinking Violet: She speaks in a soft voice, and she's rather sensitive and easily prone to tears.

    Hot Dog Princess 
https://static.tvtropes.org/pmwiki/pub/images/hot_dog_princess_5226.png
Voiced by: Maria Bamford

A princess who rules over the Hot Dog Knights.


  • Abhorrent Admirer: After Finn saves her, she tries to kiss him. However, he doesn't want to get kissed by her because he says that she smells like "old hot dog water".
  • Cloudcuckoolander's Minder: Instead of the knights protecting their ruler, most of the time it's the other way around.
  • Distressed Damsel: She requires saving pretty regularly. Her knights are even worse.
  • Princesses Rule: Apparently the only ruler of the Hot Dog Kingdom.
  • Visual Pun: Instead of actual hot dogs, she and the Hot Dog Knights look like a cross between hot dogs and dachshunds—which makes them literal "wiener dogs".

    Desert Princess

  • Canon Foreigner: Created for the comic book series.
  • Cool Crown: Her crown is made of ice cream, with a cherry on top.
  • Dishing Out Dirt: Can create objects from sand and then control them.
  • Fusion Dance: The second issue implies that she is actually an amalgamation of various Candy citizens.
  • Last Kiss: When Desert Princess's sand clones are told to throw themselves in the giant hole they say they want a kiss from Finn first. After they get their kiss they dissolve into lifelessness without any further objection.
  • Princesses Rule: Claims to rule the Desert Kingdom.

    "I'm not crying, Finn. My tear sac is broken."
  • Hypnotize the Princess: The Ice King gets her to accept his engagement with a cursed engagement ring.
  • Mind-Control Eyes: You can tell she is hypnotized because when you examine her eyes closely enough you can see a miniature version of her behind bars in each one.
  • Open the Iris: The entirety of her eyes, white, iris, pupil and all get huge under mind-control.
  • Younger Than They Look: Old Ladies are their own race of people in Ooo, so Old Lady Princess may not actually be that old.

Jake and Lady Rainicorn's Puppies

    General Tropes 

  • Badass Family: After two days they were more capable in a fight than their (admittedly sleep-deprived) father.
  • Everything's Better with Spinning: Their fused form spins rapidly to attack.
  • Explosive Breeders: One thousand years in the future Rainicorn/Dog hybrids are the dominant species on Ooo's main continent, having supplanted the Candy Kingdom and driven them from their lands.
  • Fusion Dance: In "Jake The Dad", to fight the foxes that were trying to eat Jake, the five of them are shown to combine into... something. They can even involve Jake in it, without him requiring any understanding of what was going on.
  • Non-Human Humanoid Hybrid: Half-rainicorn, half-magic dog. well quarter dog and quarter something else.
  • Rapid Aging: They become adults in less than a week.
  • Superpowerful Genetics: The original five pups were all born with at least one power, a variation of either Jake or Lady Rainicorn's abilities. After a thousand years of breeding and hybridization, future pups are capable of manifesting some devastating powers, if not for Gibbon's efforts to extinguish the powers of his subjects.
  • Uneven Hybrid: One half rainicorn, one quarter dog, one quarter whatever it was that impregnated Joshua.

One of Jake and Lady Rainicorn's puppies, who inherited Jake's mischievous side.


  • Eyeless Face: Unlike the other pups, she doesn't have visible eyes or a nose. She does have several wrinkles on her face, but exactly what they are or why her face is like this is unclear. She also has an unusual mouth which appears to open both horizontally and vertically, and her horn is on her lower back. Turns out her odd face may be inherited from her extra-dimensional "grandfather".
  • Gender-Blender Name: She's a girl named Jake.
  • In the Blood: She has recently become a thief like her father was in his youth.
  • Rapid Aging: Despite being less than a year old chronologically, she stated in her second appearance that she was 22, then in the very next episode, she was "basically" 30.
  • Voluntary Shapeshifting: Her hair can grow and be controlled in the same way her father controls his body.
  • Wacky Parent, Serious Child: In "Another Five More Short Graybles".
  • "Well Done, Daughter!" Girl: She wants Jake to be proud of her. He is... especially after she demonstrates what a skilled criminal she is.

  • Legacy Character: Ends up restarting Joshua and Margaret's investigation agency.
  • Manchild: He's the same age as Kim Kil Whan, but acts like a teenager.
  • Momma's Boy: In the sense that he still lives with Lady (and uses her shampoo), but he also seems the closest to her out of all the pups. At the end of "Lady Rainicorn of the Crystal Dimension", he tells her he wants to "learn to be cool, like you."
  • Mr. Imagination: He imagines himself as part of BP's diary.
  • Rapid Aging: Like the rest of the puppies, though he still acts the most childish.

  • Foolish Sibling, Responsible Sibling: The responsible sibling to Jake Jr. and TV's foolish siblings.

  • Jerk with a Heart of Gold: He's not a bad guy, but he's kinda a large jerk to his father in the course of trying to teach him responsibility.
  • Landlord: Becomes this to Finn and Jake, buying their treehouse out from under them.
  • Rapid Aging: Even more noticeable than his siblings. He has a beard by three days old.
  • Rules Lawyer: Jake digs up a golden bone in his yard to buy back the treehouse. Kim Kil Whan reasons that since the yard is his property, the bone already belongs to him.
  • Took a Level in Kindness: Kim does grow more patient with his dad. In his second episode, we see him participating in a three legged race with Jake before asking him for help with his daughter.

  • Non-Human Humanoid Hybrid: Where to begin? She is half bear from her mother's side while Kim is of course, half rainicorn from Lady and half dog from Jake while Jake himself is technically half dog and half extradimensional creature, thus, all of his kids would be one quarter dog and one quarter alien being, thus Bronwyn is half bear, quarter rainicorn, 1/8th dog and 1/8th alien

  • Badass Normal: By Ooo's definition of normal, anyway. Neither of them have stretchy powers like Jake, but are shown to be able to handle enemies powerful enough to beat their super-powered sons easily.
  • Battle Couple: They're Happily Married and both of them work together in their monster hunting business.
  • Cool Sword: Joshua was the original owner/creator of the Demon Blood Sword.
  • Deceased Parents Are the Best: Played with; though flashbacks show that they had their shortcomings (Margaret insisted on following a guide to raising their children that kept them from even the smallest dangers and Joshua encouraged his sons to beat each other up in order to be "tough galoots"), Finn and Jake still remember them fondly.
  • Face Full of Alien Wing-Wong: A monster bit Joshua and implanted an egg in his head, which resulted in Jake's birth.
  • Good Parents: Played with: Margaret insisted on strictly following a guide on how to raise children, refusing to expose her sons to even the slightest risk, while Joshua was a strict father who wanted his children to be "tough galoots". However, both of them do love their children very dearly despite these shortcomings.
  • Kleptomaniac Hero: As Jermaine reveals Joshua stole alot of stuff from demons... and the demons want their stuff back.
  • Happily Married: While they have their disagreements, they clearly love each other and have a stable married life.
  • Lookalike Lovers: They look very similar to one another, with the only things that differentiate them being their hats and Margaret's earrings and long eyelashes.
  • Motor Mouth: Joshua tends to talk like this.
  • Mr. Seahorse: Joshua is the one who gave birth to Jake, who popped out of his head after he got bitten by a monster.
  • Posthumous Characters: Both are dead by the time of the first episode, but they appear in flashbacks.
  • Pregnant Badass: Although her pregnancy prevents her from being as deadly as usual, Margaret manages to defeat the monster who bit Joshua by herself.
  • Scars Are Forever: The reason why Joshua always wears a fedora is to hide a scar he got from giving birth to Jake through his head.
  • Would Hurt a Child: Double Subverted by Margaret: When she's under the impression that the monster she needs to defeat in order to save her husband is a baby, she starts to apologize... then socks it in the face to take its venom.

    Jermaine 
https://static.tvtropes.org/pmwiki/pub/images/adventure_time_jermaine.png
Voiced by: John DiMaggio ("Crystals Have Power"), Tom Schlarpling ("Jermaine" onwards)

Finn and Jake's third brother. He appears early on in flashbacks, but doesn't appear in person until "Jermaine".


  • Aloof Big Brother: Well he's not their big brother, but Jermaine acts like it, preferring to do his own thing. He loves Finn and Jake, but he doesn't get their childlike behavior, so he spends most of his time painting.
  • Badass Normal: Despite not having powers, he holds his own when it comes to dealing with demons.
  • Big Ol' Eyebrows: Pretty much the only thing that makes him visually distinct from Jake.
  • Cool Big Bro: Shows Jake his love and support when Jake comes to visit him in Abstract and helps Jake get past his denial over his revelations and changes. He says that Joshua did inform him about the potential changes, but that he would've been there for his brother anyway.
  • The Dutiful Son: Spends his life watching over their father Joshua's stuff, and is jealous of the adventurous life that Finn and Jake lead. Subverted, when Jake points out that he could have left any time he wanted, and Jermaine agrees that he "built his own cage".
  • Foolish Sibling, Responsible Sibling: The responsible one in the family. He makes more than one shot about his brothers living in a "playhouse".
  • Green-Eyed Monster: Gets in a fight with Jake over his jealousy that Jake was their father's favorite, while he was left to take care of their father's stuff.
  • Middle Child Syndrome: Never explicitly stated, but adds up to the sibling birth order revealed in "Joshua and Margaret Investigations" and to Jermaine's issues towards his brothers (see The Resenter below).
  • Only Sane Man: He's a lot more down-to-Earth than either Finn or Jake, and can easily slip into this role when he's around them.
  • The Resenter: Has a lot of pent-up resentment towards his brothers. He gets over it in his titular episode.
  • Took a Level in Cheerfulness: He's a lot happier now that he's free to do what he wants. He started out as a landscape painter, though has since shifted to abstract painting (something which bothers Jake, since he's known him for painting landscapes.)
  • Visual Pun: He's figuratively and literally a watchdog; he's spent years keeping watch over his father's house and making sure the demons can't steal back their possessions that Joshua took from them, and he also wears a wristwatch that reminds him to turn over a tape in order to keep one of the demons at bay. When the house has burned down and the tape is destroyed, Jermaine throws away his watch since he no longer has to guard anything.

Kent quickly learned to talk, grow appendages, and after Shelby gets advice on brothers from Jake, Go and beat bad guys, which begins his first adventure into the tree itself.


  • Chaste Hero: due to being born literally a few minutes earlier, when the Rat Knight gives him a choice of love or the magic earth he has, Kent picks the earth without a second thought.
  • Does This Remind You of Anything?: The party that led to his creation in the first place, along with the fact that Shelby passes out and wakes up from said party not remembering what happened.
  • Expy: He shares many Similarities with Nintendo's Kirby, both are small, round, pink, baby-like characters that go on an adventure blissfully to defeat a nightmarish villain.
  • The Hero: To the little people living in the tree.
  • Maybe Magic, Maybe Mundane: Kent just sort of comes into being, and its unknown whether or not this just happens with a worms body pieces being cut, or if there was some outside influence behind his.
  • Sorting Algorithm of Mortality: Lampshades that he has no real sense of mortality, and slides between areas 1 and 2 of the scale.
  • Troll/Troubling Unchildlike Behavior: His parting words to Jake are, and quote Someday, you'll be Kent's food. end quote; afterwards he scoots away laughing goofily. He seems to have grown out of it rather quickly though.

Voiced by: Vincenzo Rauso (Season 1), Collin Dean (Season 5 & 6)

A member of Jake's old gang of criminals. He desperately wants to be friends with Jake again.


  • Arch-Enemy: He considers Finn to be his.
  • Ax-Crazy: Finn can't even get Tiffany to stop trying to stab him long enough for them both to fight giant worms.
  • The Bus Came Back: He's used for a one-off joke in "My Two Favorite People", and doesn't return again until "One Last Job", where he gets a much larger role.
  • Crazy Jealous Guy: He wants to be Jake's best friend again, and he will let nothing stop him.
  • Delusions of Eloquence: He makes a lot of long, flowery speeches, but they're entirely meaningless and he has to write them down on his arm so he doesn't forget the words.
  • Enemy Mine: He and Finn have to work together in "Dentist".
  • Gender-Blender Name: He's a boy.
  • Ice-Cream Koan: Tends to make meaningless cryptic speeches.
  • I'll Kill You!: He makes no secret of his murderous intentions towards Finn.
  • Jabba Table Manners: Eats like this after losing his teeth.
  • Murder the Hypotenuse: He plans to murder Finn so as to have Jake all to himself.
  • Never Found the Body: He gets eaten by a giant worm in "Dentist", but it's implied that he's still alive. This is confirmed in "Preboot", when he shows up as a Cyborg; however, the episode ends with the ship he's on exploding. Finn nevertheless says to Jake that he's "probably" okay to spare Jake's feelings.
    • In the ending montage there's a brief shot of an adult cyborg Tiffany wandering through a wasteland.
  • Perma-Stubble: Played for Laughs, as his stubble is simply pubescent peach fuzz.
  • Stalker Shrine: He has one of these devoted to Jake.
  • The Tooth Hurts: He lost all of his teeth biting into the Baker's Shard.
  • Vague Age: Looks and sounds about Finn's age and is a bit shorter than him, but apparently ran with Jake back when he was criminal, which is implied to have been a while ago.
  • Vocal Dissonance: He's a conniving, murderous criminal with a penchant for villainous monologuing, but he has the voice of a little kid.

Voiced by: Jeff Bennett

An anthropomorphized goose with an extremely wobbly neck and limbs who speaks mostly in rhyme and sells all kinds of adventuring gear. Choose Goose sometimes teases Finn to manipulate him into buying his wares, but is mostly on good terms with him and Jake.


    Banana Man 
https://static.tvtropes.org/pmwiki/pub/images/ae1a697dbbe05232c9aa9296858b18df.png

A... well, a Banana Man who is probably the best engineer in Ooo. According to an apparent "croak dream," he will be present at Jake's death, though the dream is later fulfilled and Banana Man actually saves Jake from his apparent death.


  • Big Damn Heroes: He shows up just in time to save Finn and Jake from the depths of space in "The Comet".
  • The Chew Toy: In his first appearance, Finn and Jake destroy his home and his rocket ship. In his second, he helps save the Candy Kingdom but gets arrested for public nudity (though it's implied that he also hooks up with a female Banana Guard).
  • The Engineer: Helps Finn and Jake fix up an old truck.
  • Gadgeteer Genius: He can build a functioning rocket ship, the technology for which was lost after the Great Mushroom War.
  • I Just Want to Have Friends: He agrees to help out Finn and Jake just because he wants to hang out with them.
  • Mr. Fixit: He can fix a truck that's been broken-down for over one thousand years.

An ancient two-headed psychic war elephant.


  • Put on a Bus: After his first appearance in "The Limit", he doesn't appear again until "Furniture & Meat".
  • The Cavalry Arrives Late: In "Come Along With Me", he arrives at the battle scene just as Betty fuses with Golb and disintegrates its monsters.
  • Time Abyss: It's been around for as long as Darren.

    Moe 

Moseph "Moe" Maestro Giovanni

https://static.tvtropes.org/pmwiki/pub/images/moe_at_1416.png
Voiced by: Chuck McCann

The creator of all MOs. He created BMO as the companion for a son, but he never ended up even dating. He eventually sent BMO out into the world to explore and learn and even find his own family to take of, to "Be more."


  • Awesome Mc Coolname: Given how his middle name means "master", he qualifies here.
  • Bus Crash: AMO claims to be Moe after going fully cybernetic, but he actually killed the real Moe.
  • Cool Old Guy: We're talking about the guy who built BMO! And thousands more robots!
  • Genius Cripple: Can't use his legs and requires his robots to carry him and for life support.
  • The Mentor: Moe is a kindly father figure who tries to teach his creations life lessons and help them find their purpose.
  • Nice Guy: Moe is almost endlessly kind and caring.
  • Transhuman: When asked by Finn if he was human, he answered "My skin is human," implying that he has survived since the Great Mushroom War as a Cyborg.
  • Where Does He Get All Those Wonderful Toys?: For a lot of Ooo, Moe is the answer to this question. Much of the advanced technology still left in Ooo appears to run on Moe's systems, and in several cases Moe has been subtly hinted at being the source of other developments. For example, one flashback shows Moe with a blueprint of the Sleeping Fire Giants that are so important to the Fire Kingdom, and the flashback also includes one of the flame giants in the process of being built just outside Moe's office.

Billy's ex-girlfriend who appears in the fifth-season finale "Billy's Bucket List"


  • Action Girl: She was a partner in some of Billy's adventures.
  • Battle Couple: This is pretty much how she described her relationship with Billy.
  • Biker Babe: In flashbacks, she could be seen riding shotgun on Billy's motorcycle and when she and Finn visit Billy's Crack, she is drawn right to it.
  • Giant Woman: She's as tall as Billy.
  • Green-Skinned Space Babe: Well, green-ish. With pointed ears for extra alien-ness.
  • Manic Pixie Dream Girl: The "pixie" part is debateable, given her size, but there are indications that she was this to Billy. And maybe, momentarily, for Finn.
  • Mayfly–December Romance: In her flashbacks, Billy looks much younger, but Canyon hasn't visibly aged at all.
  • Statuesque Stunner: She's 20 feet tall and gorgeous.

    Breezy the Bee 
https://static.tvtropes.org/pmwiki/pub/images/38432c88eb9941828be093b63bc95600.png
Voiced by: Ashly Burch

A Female Bee that Finn meets after his final confrontation with The Lich. At first, she only seems interested in the flower growing from his armless stump — being Finn's friend and getting him princess kisses to re-ignite his "spark" and keep the flower from wilting — only to get closer to it rather than him. After some bonding, she grows to love Finn. (Enough to drink royal jelly and become a Queen Bee to protect him from other bees.)


  • Adorkable: Seems to share many aspects with Finn, including getting very nervous when in a more emotional situation.
  • The Bus Came Back: She eventually makes an appearance in the short "Frog Seasons, Spring (Again)".
  • Chuck Cunningham Syndrome: Her one appearance had a HUGE impact, as you can no doubt tell from the spoilers, and she's even teased as a love interest who can be everything Finn has ever wanted, but she abruptly disappears and has yet to so much as be referenced ever again.
  • Foil: To Princess Bubblegum. Breezy, being a queen bee who loves Finn and needs a knight, contrasts PB being eternally a princess with no plans to marry and become a queen, and not returning Finn's affection. Breezy is literally everything Finn ever wanted from PB but cannot receive, and dialing up the irony is the fact that this time, it's Finn who doesn't return the affection. Lampshaded via symbolism when Finn sees her silhouette near the end of her episode, and he mistakes her for Bubblegum for a moment.
  • Interspecies Romance: Though it doesn't start off as such, it begins with Breezy simply wanting the flower that came out of Finn's arm stump at the Citadel. Through the episode, the friendship blooms into her feeling affection to Finn, rather than the flower. Though she is just a bee, she becomes a more humanoid Queen after stealing royal jelly to protect Finn. However after that, Finn still sees her as just a friend and she seemingly leaves. After that, she returns after Finns attempts making out with LSP fail to keep the flower from wilting, and her singing seemingly sparks enough passion to make the flower literally explode into a tree and give Finn's arm back. This seems to spark his interest in her, but only time will tell if this goes anywhere.
  • Jerk with a Heart of Gold: Only wants to help Finn to keep the flower alive, but grows out it as she spends more time with Finn.
  • The Power of Love: She returns to Finn after she leaves him for saying that he thinks they should just be friends and spends the night with LSP. The two perform a duet which makes the flower blossom until it explodes and returns Finn's arm. Bonus points in Finn that he sees PB during the song and realizes it's Breezy afterward, with an awed expression.
  • Psychic Powers: In her Queen Bee form, though it isn't certain whether this only extends to other bees or not.
  • Rebellious Princess: To get Finn to continue being responsible for the flower, she eventually tells Finn that she's a Virgin Queen Bee, running from her responsibilities. She eventually gets over this for Finn's sake.
  • She's Got Legs: In her Queen form, she has a shapely waist and legs after getting her new body. Justified in that, much like real bees she has pollen sacs in her legs (though hers look more like belt pockets.
  • Transformation Sequence: Goes through a somewhat unsettling one to rescue Finn out of love, becoming a humanoid bee creature. To be specific, she vomits honey which wraps around her, making her grow and form her humanoid appearance.
  • Walking Spoiler: Wouldn't expect that out of a simple bee, would you?
  • Wingman: What she becomes to Finn after they first meet.

Past Characters

    Shoko 
https://static.tvtropes.org/pmwiki/pub/images/shoko_8137.png
Voiced by: Isabelle Fuhrman

First appearing as a ghost in third season episode, "The Creeps", Shoko was a one-armed vagabond and mercenary with a tiger companion when she was still alive, and stole a powerful amulet from Princess Bubblegum in the time of the Candy Kingdom's founding. She dies in the attempt by falling into a radioactive river, but as "the Ghost Lady," she haunts the vault of Finn's mind, yearning for atonement. Finn is actually her reincarnation.


  • Action Girl: A girl who rides a tiger and is a mercenary.
  • Action Pet: Her tiger, who is also her mount.
  • Ambiguously Human: Even though she has a name and upbringing from a distinctly human ethnicity, it's not quite certain what kind of humanoid she is.
  • An Arm and a Leg: Her parents trade her right arm for a laptop, and she's taught that it's a worthy trade.
  • Artificial Limbs: Bubblegum makes her a robot arm in return for helping build the Gumball Guardians.
  • Ascended Extra: Originally part of a one-off Gainax Ending gag in "The Creeps".
  • The Atoner: The reason why she haunts Finn's dreams. She wanted to return Bubblegum's amulet that she stole in life.
  • Body Horror: Falling into a moat of radioactive Mutagenic Goo turned her into a weird worm-like creature. On the plus side, her right arm grew back.
  • Chekhov's Gunman: Turned out to be a lot more important than she first appears...
  • Continuity Nod: She shares the trademark artificial arm that most alternate versions of Finn possess, highlighting her relation to him as his prior incarnation.
  • Foreshadowing: Shoko is missing an arm, as do all alternate universe versions of Finn. As of "Escape From the Citadel", Main!Finn is finally missing one too.
  • Handicapped Badass: She's missing an arm but an experienced mercenary.
  • Hilariously Abusive Childhood: Her parents traded her arm for a laptop, teach her that computers are worthy of such a tradeoff, and she just thinks such a sentiment is completely normal.
  • Nuclear Nasty: She emerges from the radioactive river as one, but quickly dies. She then haunts Finn in that form.
  • Our Ghosts Are Different: Her first appearance in "The Creeps", as well as in her cameo appearances afterward. "The Vault" implies that the castle from "The Creeps" was originally the base of the Bath Boy Gang who gave Shoko her final job, which suggests that she wasn't exactly a ghost, but part of a past life vision Finn was having.
  • Parental Abandonment: Left at a dojo by her parents.
  • Past-Life Memories: Most of what's known about her is from Finn's mental "Vault".
  • Reincarnation: The most recent past life of Finn Word of God also confirmed her tiger is a past life of Jake, as Finn and Jake are almost always reincarnated together in some form.

    Urgence Evergreen 
https://static.tvtropes.org/pmwiki/pub/images/9dfb334096441e47b0920a456d2c6e49.png
Voiced by: Tom Kenny

Millions of years ago, Earth was protected by four elemental guardians representing Ice, Flame, Candy and Slime. The strongest in their number was Urgence Evergreen, master of ice. With this power and stature came arrogance and would lead to his undoing in an effort to stop a sinister comet through the creation of a magical wishing crown.


  • Abusive Parents: He's Gunther's father in a way due to stealing his egg and giving him intelligence, and is an emotional abusive prick who demeans him. He only starts to realize this right before is death.
  • Elemental Embodiment: He is the elemental of ice.
  • Good Is Not Nice: Despite being an arrogant, weapons-grade Jerk Ass and extremist, he is genuinely trying to save the world from mass destruction.
  • Greater-Scope Villain: Downplayed — he's not evil, just a jerk, but having created the Ice Crown and cocking it up he's responsible for all the trouble the Ice King causes. He's also the basis for his crazy personality.
  • Heel Realization: When Gunther is driven to madness by the crown, he tries telling him to use focusing chants to regain his sanity "like I taught you", only to realize he never got around to teaching him anything.
  • An Ice Person: The original one on Earth/Ooo.
  • Jerk Ass: Takes Gunther for granted and continually keeps him at a distance and refusing to teach him magic. He also freezes his colleagues when they choose not to get involved with Wish Magic.
  • Jerkass Has a Point: Though he doesn't give the appropriate response, he's absolutely right that the green Catalyst Comet is not to be taken lightly since it's the prior incarnation of the Lich.
  • Meaningful Name: Evergreen trees thrive in cold, northern climates.
  • Nice Job Breaking It, Hero!: "Hero" is pushing it, but he does try to use the Ice Crown to stop the end of the world. However, his abuse towards Gunther causes him to fail at stopping the extinction of the dinosaurs, and create an Artifact of Doom that causes people to turn into a crazy, inferior version of himself and could start a new Ice Age if overwhelmed.
  • Red Herring: The episode of the same name suggests that he might have been reincarnated as the Ice King, considering they're both wizards with ice powers, share similar physical appearances, and even have the same voice actor. The episode "Elemental" reveals that he's not: Ice King is just Gunther's imitation of Evergreen, while his most recent reincarnation has been a Human Popsicle since before the Mushroom War.
  • Replacement Goldfish: In a sense, people who put on the crown are this, as the crown transforms its wielder into Gunther's crazy, skewed version of Evergreen.
  • Super Prototype: The Ice King's powers came to be when Gunther used the crown's wish magic to turn him into a magical impression of Urgence. Because of this, Ice King has all of Urgence Evergreen's abilities, but his madness and lack of skill make him (and by extension all other wearers a crown) nothing but a twisted, inferior xerox of the real Evergreen.

    Gunther 
https://static.tvtropes.org/pmwiki/pub/images/ebd64dfb8a68c2e86aace9f399f6e073.png
Voiced by: Pamela Adlon

A young green dinosaur that Evergreen granted intelligence to serve as his assistant. Despite Evergreen's refusal to teach him magic and continually putting him down, Gunther sees Evergreen like a father and eagerly jumps at the chance to learn magic or join on Evergreen's adventures. Accompanied by a yellow proto-mammal cat named Nina.


  • An Ice Person: Becomes the original Ice King after making his wish on the crown.
  • Brain Uploading: His mind lives on inside of the crown, along with everyone else who's ever worn it, including Simon and the original Santa Claus.
  • Hero-Worshipper: He remains extremely loyal to Evergreen, no matter how badly he gets mistreated by him. In the end, his wish to emulate Evergreen is so great that it overpowers his desire to save the world, turning him into the first Ice King. The thing is, because Evergreen never taught him any spells and the only thing he learned from the wizard was to say "Gunther, no!" all the time, he became a clone of Evergreen that only shouted, "Gunther, no!". Evergreen realizes this too late and can only watch as the comet destroys the world while Gunther chants "Gunther, no!" over and over again..
  • Madness Mantra: After wishing to become more like Evergreen. The thing is, he didn't become exactly like Evergreen, but how he perceived Evergreen to be: a man who constantly scolded him. Gunther, no! Gunther, no! Gunther, no! Gunther, no...
  • The Man Behind the Man: A non-villainous variant. He winds up becoming the original influence of Ice King's crown.
  • One Steve Limit: Averted, Gunther is also the name of Ice King's penguin. Of course, he's the reason that's the case.
  • Reincarnation: It's implied by the title card and the Ice King's desperate obsession with being Finn and Jake's friends that Gunther and Nina are the earliest incarnations of Finn and Jake, respectively.
  • Small Role, Big Impact: Considering he and Evergreen were directly at (or at least pretty close to) the Lich comet's impact point, Gunter most likely only wore the crown for a moments at most. However, that was still enough time to create and lock the Ice King persona into the crown, sealing the fates of all those who would wear it after him.
  • Uplifted Animal: Gained intelligence and speech when Evergreen mutated him in the egg.
  • With Great Power Comes Great Insanity: When using the wishing crown, his desires to be like Evergreen emerge, turning him into the original Ice King. However, because Evergreen never taught Gunther anything and constantly scolded him, he turned into what he perceived Evergreen to be: a man who always says "Gunther, no!". And the ice magic he performs is weak compared to the real Evergreen.

    Patience St. Pim

Voiced by: Lauren Lapkus

A woman from before the Mushroom War who is the newest Ice Elemental. She froze herself before the bombs fell and was unfrozen by Ice King, Finn, and Jake. She wants to be friends with the other elementals (PB, Flame Princess, and Slime Princess) but they don't like her since she had the Ice King kidnap them.


  • Ambiguously Evil: She's trying to make friends with the other elementals and teach them to use their powers, but the lengths she'll go to do such things are quite extreme and her ultimate plans seem uncertain.
  • An Ice Person: As the Ice Elemental, her powers are equal to or greater than Ice King's as well as more fine-tuned. Note how smooth and clean-looking her ice constructs are.
  • Elemental Embodiment: The reincarnated Ice Elemental from before the war.
  • Gone Horribly Right: She managed to complete her spell to put herself and the elemental princesses in full touch with their power, but the others were overwhelmed by their powers.
  • Human Popsicle: How she survived the Mushroom War. At the end of the "Elements" mini-series, she does so again.
  • Humanoid Abomination: After casting the Elemental Spell.
  • Ironic Name: Her name is "Patience" but she is extremely hyperactive.
  • Karma Houdini: Ends up screwing Ooo over big time, however never faces any comeuppance for it. She just ends up freezing herself so she can try again in the future.
  • Reincarnation: As the ice elemental, she's Urgence Evergreen's reincarnation.
  • Took a Level in Badass: When she awakens in Ooo, with a lot more magic around than there was pre-Mushroom war, she's significantly more powerful, able to match or even exceed Ice King's despite him having 1000 years to learn how to use his power.

An odd figure from the future, and narrator of stories he calls Graybles.

  • No Fourth Wall: He routinely speaks directly to the viewers.
  • Suddenly Fluent in Gibberish: Peppers his sentences with nonsensical words. For example.
    Cuber: I'll see you crimpy glimmers on triode flimpin' the diode.

    Shermy & Beth 
https://static.tvtropes.org/pmwiki/pub/images/shermy_and_beth_at_finale.jpg
Shermy on top of Beth
Voiced by Sean Giambrone (Shermy) and Willow Smith (Beth)

Two adventurers from 1000 years in the future who in their travels discover Finn's prosthetic arm and learn of the events of the Great Gum War.


  • All There in the Manual: All the information about the Pup Kingdom is largely drawn from writers, artists, and producers showing off conceptual stuff online.
  • Cartoon Creature: Shermy looks like some cross between a cat, a monkey, a mouse, and a human. In a future where Rainicorn Pups are the continent's dominant species, that sort of thing may be more common. He's actually just a cat, but he looks quite a bit different than the others in the show.
  • Cat Smile: Shermy. As he's a cat, it's not really surprising.
  • The Exile: Beth is wanted by the Pup Kingdom for opposing King Gibbon's rule.
  • Framing Device: The future King of Ooo tells the two the story of the Great Gum War.
  • Generation Xerox: Two best friend adventurers who travel the world of Ooo, like Finn and Jake. Shermy is excitable and always ready for adventure while Beth is more cautious and reserved. Shermy is implied to be Finn's reincarnation and Beth is Jake's direct descendant. At the end of the story, Shermy inherit Fern's Finn Sword as well.
  • Keet: Shermy's. He's an excitable ball of energy that seems to love adventuring as much as Finn.
  • La Résistance: They fight against the Pup Kingdom.
  • Last Episode, New Character: Introduced in the series finale.
  • Portmanteau: Shermy's name is actually a combination of the last and first names of Finn's voice actor, Jeremy Shada.
  • Reincarnation: Possibly, of Finn and Jake, together again as many times before...
  • Rebellious Princess: Beth is in exile because she rebelled against the King of the Pup Kingdom for his theft of magic from other Rainicorn Pups.
  • Red Oni, Blue Oni: The energetic Shermy acts as the red to the more responsible, laid-back Beth's blue.
  • Thinking Up Portals: Beth has the ability to open portals through her navel.
  • Tiny Guy, Huge Girl: Exaggerated; Beth completely dwarfs Shermy in size, the former around the size of Donny and the latter about a head taller than BMO.

    The Ice Thing 
Voiced by Tom Kenny

The Ice Thing rules over the Ice Crowndom 1000 years in the future. He's fused completely with the Ice Crown as a flying beard with the crown's gems for eyes.

In "Come Along With Me", it's revealed that the Ice Thing is the future version of Gunter, who took the Ice Crown after Simon reverts back to normal.


  • Almighty Idiot: Give an ancient cosmic being (Orgalorg) of incredible power a crown with immense magical properties? You end up with an insane cackling creature with barely any sapience.
  • Animal Nemesis: Slightly inverted, as it's implied he constantly attacks the Pup Kingdom to try to reclaim his stolen ruby eye.
  • Dismantled MacGuffin: He's missing one of the rubies of the Ice Crown. He originally removed it to give to Turtle Princess as their wedding ring. However, Gibbon of the Pup Kingdom somehow got it and replaced his eye with it to use ice magic. Only having 2/3rds of the crown's power may be why he became a mutated, mad beast.
  • Driven to Madness: Okay, the Ice King was always insane, but the Ice Thing in the present is still capable of speech and interaction. In the future, he's completely lost it, as all he does is cackle and fly around. Averted when it turns out he's not Ice King at all, but Gunter transformed by Ice King's crown.
  • Eye Scream: Played with, since he originally gave up one of his eyes willingly to Turtle Princess, but clearly wants it back now that Gibbon has it.
  • Laughing Mad: All it does is cackle.
  • Memento MacGuffin: His missing eye isn't just a magical artifact, it's also his wife's, possibly dead by this point, wedding ring.

    The Prizeball Guardians 

The successors to Candy Kingdom's Gumball Guardians, these towering machines wander the Land of Ooo, seemingly serving as protectors the the Candy Kingdom citizens they hold in stasis within themselves.


  • Colony Ship: A purely terrestrial variant. They hold the citizens of the Candy Kingdom in stasis, presumably to keep them safe from the likes of Gibbon and his Pup Kingdom.
  • Humongous Mecha: They are gigantic, easily dwarfing the old Gumball Guardians.
  • Superior Successor: To the Gumball Guardians.
  • Your Head Asplode: Cuber does this to one of them.

Humans

    Marceline's Mother 
https://static.tvtropes.org/pmwiki/pub/images/marcelinesmomstakes.jpg
Voiced by: Rebecca Sugar

First seen in a flashback in "Everything Stays", she was a human woman who gave birth to Marceline right before the Mushroom War.


  • Ambiguously Brown: She either has a dark tan or may have mixed blood in her family.
  • Creator Cameo: Voiced by Rebecca Sugar, an ex-storyboard artist responsible for much of Marceline's development.
  • Good Parents: From the little that is seen, she certainly does a good job raising a half-human/half-demon child (presumably by herself mainly).
  • Interspecies Romance: Had one with Hunson Abadeer at some point.
  • Posthumous Character: Likely dead due to how far off into the future the series is. She only shows up briefly in a flashback.
  • The Unreveal: Beyond her name being unrevealed, just how she got into a relationship with Hudson Abadeer, especially considering this was before the return of magic. In fact, her first words heard was her finishing this story to a young Marceline:
    Marceline's Mother: Then he said fine. And that's the story of how I met your dad.
  • Unnamed Parent: We're never told her name, and we only know that she's Marceline's mother from the conversation she was having with her.

    People of the Islands 
The Islands are an archipelago in which Humans live. They were founded by Two Bread Tom and his followers nearly a thousand years before the events of the show.

The Islands in General:

  • Defector from Decadence: The "Hiders" are people who try to escape the Island.
  • Fantastic Caste System: The human society on the Islands seemss to have a some sort of caste system, although notably not every member of the Island society seems to be part of a caste. The three currently known castes are Experimentersnote , Seekersnote  and Helpersnote 
  • Police State: Their society has a group of elite solders who drag any one attempting to leave off to re-education. Minerva replaces these with her fleet of robots, which initially seems to be even more controlling, but Finn convinces her to lightening off and allow people to leave.

    Jo 
Voiced by: Ava Acres

Jo (AKA Bunny Girl) Is a young girl first appearing in the Stakes mini-series in which she befriends a younger Marceline. She later stars in the Adventure Time Islands Graphic Novel.


  • Action Girl: As she spends more time in the wilderness of Founders Island she learns how to survive and grows into an action girl.
  • Calling the Old Man Out: At the end of the Islands graphic novel she calls out Two Bread Tom on his extreme paranoia of the nature and wild life of the Island.
  • Nature Hero: Seems to have become one by the end of the Islands Graphic Novel.
  • Posthumous Character: Considering she was around almost a thousand years before the events of the show and is a normal human it's really likely that she is dead long before the time of the show.
  • What Happened to the Mouse?: So far we haven't learned what happens to her after the Islands Graphic Novel or what her ultimate fate is.

    Susan Strong 
https://static.tvtropes.org/pmwiki/pub/images/176px-Susan_235.png
Voiced by: Jackie Buscarino

A member of an underground-dwelling group of humans. The "humans" she lives with are eventually revealed to be hyoo-mans, a strange race of Fish People living in the ruins of human civilization. Susan herself is the only true human amongst them. She gets a focus arc in season 8 explaining her origins. Her real name is Kara, and she was an elite member of humanity's "Seeker" caste who was sent to Ooo 16 years ago to find Martin and baby Finn and bring them home, but somehow ended up getting lost herself.


  • Ambiguously Gay: She has an extremely close relationship with Frieda in the season 8 mini-series.
  • Ambiguously Human: She is fully human, though she does have some cybernetic implants from her home.
  • Cowardly Lion: Better than the rest of her people, certainly.
  • Expy/Shout-Out: Of Tarzan, much like Finn. In Susan's case it's a lot more obvious, since she's Raised by Wolves that don't act civilized but live as a group which she leads, and she doesn't speak fluent English.
  • Green Eyes: Not that they really indicate anything though.
  • Huge Schoolgirl: Big in every way. There is pretty much no physical indication of youth, leading to her Vague Age. Played straight(er) in the "Islands" flashbacks: Susan was already extremely muscular as a young teen thanks to her Seeker training — however this had very little impact on her social life (since this was perfectly normal for Seekers), and actually had a positive effect on her self-image because she loved being buff.
  • Phlebotinum Rebel: Susan was trained and cybernetically augmented by Doctor Gross into being her most powerful Seeker, and ultimately plays a key role in defeating her.
  • Right for the Wrong Reasons: It turns out Strong really is her surname. All humans from the Mysterious Islands are given a designation comprised of a serial number combined with their last name: Finn's is P-G-8-7 "Mertens" and hers is X-J-7-7 "Strong."
  • Small Role, Big Impact: Susan was the one who "introduced" Finn's parents to each other — she broke both of Martin's legs during a Seeker mission and dropped him off at the hospital where Minerva worked.
    Minerva: What've you got for me, Kara?
    Susan: A sad old hider with two busted legs.
    Minerva: Oooh, I love busted legs!
  • Spell My Name with an "S": The hyphenation of her serial number is different in each of its appearances — when first shown on her cranial implant it reads "X-J-7-7", then "XJ-77" when displayed on a computer monitor, and finally as "XJ-7-7" when shown on BMO's face.
  • Sweet Tooth: She, along with the rest of her tribe, actually tries to eat the entire Candy Kingdom.
  • Took a Level in Badass: In her second appearance she's the leader of the Hyoo-mans in all but name, conquers some major fears, and is generally a ferocious warrior. Zig-zagged — she was actually regaining levels of badassery that she had lost when she lost her memories.
  • The Unreveal: We never find out if she's a fish person like the others, or a real human.
    • At the end of 'Beautopia' after she gently moves Finn's hand beneath her hat, we don't get to see whether or not there's a set of gills there or a human ear. Finn's reaction and Susan's Character Development imply that she is human.
    • Though her eyes did glow in the dark like the rest of the fish people in 'Beautopia'.
    • The question finally gets a conclusion that only opens up more questions in "Dark Purple": she IS a human, but also has a cybernetic implant.
    • These questions all get answered during the "Islands" mini-series, but bring up yet more questions. Namely, it's never explained how Susan lost her memories or ended up living with the Hyoo-mans.
  • Vague Age: She and Finn have more than a little chemistry, and Hulk Speak and Naïve Newcomer aside they seem to be on the same intellectual level. However, Susan's body type is very much that of an adult woman. The season 8 mini-series shows that she is at least 15-20 years older then Finn, as she knew his parents before he was born and was sent to retrieve him when he was an infant.
  • You No Take Candle: When Finn and Jake first find her, she barely knows how to speak until the two heroes teach her and she steps up to this trope. She's getting better at speaking though, as seen in "Beautopia". When she regains her memories, she speaks perfect English again.

    Alva

A human woman of Swedish descent at a scientific outpost on the Weather Island.


    Frieda 
Voiced by: Jasika Nicole
A human "Experimenter" from the Islands.

    Minerva Campbell (MAJOR SPOILERS) 
https://static.tvtropes.org/pmwiki/pub/images/minerva_campbell.jpg
Voiced by: Sharon Horgan

Finn's mother, a human "Helper" from the Islands. She met Finn's father Martin after he was injured trying to escape. When Martin ran from attackers with Finn in tow, accidentally landing them both off the island, Minerva was so distraught that she rededicated herself to her work harder than ever. After a deadly virus outbreak leaves her terminally ill, Minerva uploaded herself into the Islands' computer, created an army of robotic version of herself to take care of everyone, and became the de facto ruler of the Islands.


  • 100% Adoration Rating: As a doctor, she was so trusted that people believed what they knew was complete nonsense just because she said it.
  • Anti-Villain: Everything she does comes from a genuine desire to keep people happy and safe.
  • Back for the Finale: She (or part of her anyway) comes with a boatload of humans to visit Ooo in the "Where Are They Now?" Epilogue.
  • Big Bad: She's the one running the Islands, keeping anyone (especially Finn) from escaping.
  • Brain Uploading: Dying from a plague, she uploaded her entire body into a computer network.
  • Chronic Hero Syndrome: Her son got his natural urge to help people from her. She even went as far as to upload herself into a computer so she could keep taking care of everyone in Islands after her body died during a plague.
  • Exhausted Eye Bags: Her tireless work as a doctor shows in the slight bags under her eyes.
  • Fantastic Caste System: She's born in the "Helper" cast, which consists of doctors and aid workers, and is very much into the role. Despite this, she seems to have eliminated the system herself, as the robots replace the visible function of Seekers and Helpers (the latter all having died) while Frieda has gone from an Experimenter to working at a toy shop.
  • Florence Nightingale Effect: She met Martin when he was in the hospital for two broken legs and she was his nurse. They started dating after she took pity on him and saved him from being taken to re-education.
  • Foil:
    • To Finn. They enjoy their work in helping others who are in need, which both can do in extreme methods. Finn takes his method of physical helping violently so long as evil is the only one trampled across his path, Minerva helps people exceptionally but peered close enough to doom her people nearly twice in her choices.
    • To Princess Bubblegum. They both shown their work to Finn on how they operate their respective colonies scientifically. Bubblegum is able to let go of her totalitarian approach with Marceline's help, while Minerva is still plagued by the thought of her husband abandoning her along with her own child only for said child help her in getting a hold of herself.
    • To Martin. Martin was a self serving sociopath who only ever cared about himself, while Minerva is empathetic to the point that she made her entire existence about helping others. Neither of them are shown to be well adjusted individuals though for very different reasons.
  • Follow in My Footsteps: She finally see her son as something other than a child to be kept safe when she finds out Finn grew up to be a "helper" like her.
  • Generation Xerox: Her character design is not only as similar as Finn's, they are just as helpful to the people around them, just in different methods.
  • Hair of Gold, Heart of Gold: Just like her son, Minerva has blonde hair and is a good-hearted person who wants to do nothing more than help people. It's true her methods can be pretty extreme, but Minerva ultimately means well.
  • Heel–Face Turn: After seeing Finn's desire and acts to help people despite growing up in Ooo, she decides maybe the outside isn't so terrible and that people should be able to leave if they want.
  • Horrible Judge of Character: She fell for Martin even though she knew he was manipulative and even explained how he'd take advantage of her before doing so. It's highly ambiguous whether she made him a better person (at least temporarily) or was just a naive do-gooder exploited by a con man.
  • Knight Templar Parent: She attempts to force her son into uploading his consciousness to the internet for his safety. Her Establishing Character Moment even shows shades of My Beloved Smother.
    Miverva: But that doesn't matter anymore! You can stay here, with me!
    Finn: Oh, I don't think that's necess— (Miverva-Bot clutches onto Finn)
    Miverva: For the rest of your life.
  • Last of Her Kind: Unless you count Finn, she's the last Helper after the rest were killed treating a plague. If you consider her to be alive.
  • Like Parent, Like Child: Minerva and Finn both dedicate their lives to helping people, though Minerva takes this much further.
  • Like Parent Unlike Child: Despite having the same core goal, her and her son's methods are complete opposite: Finn tries to protect people by fighting evil, sometimes to the point of being excessively violent. Minerva tries to take care of people to the point of coddling them.
  • Logical Latecomer: She's lived in a Hidden Elf Village all her life, and considers what Finn shows her of the rest of Ooo not just dangerous but also bizarre.
    Minerva: Your world seems so chaotic. Your ruler is a piece of gum, your friend's a vampire, you dated a bit of fire—Your life is constantly in danger!
  • Meaningful Name: Shares her name with the Roman goddess of wisdom and medicine.
  • Missing Mom: She was separated from Finn when he was a baby and he never got to meet her until their encounter in Islands.
  • My Beloved Smother: When she finds out Finn is alive and came to the Island, she insists he can't leave, even though he has a whole life outside.
  • Nice Girl: She's overprotective, but other than that's she's a helpful and well-intentioned person.
  • Not Even Bothering with the Accent: Her voice actor uses her natural Irish accent, which no one else on the Islands has.
  • Opposites Attract: A tireless, trusting, over-protective doctor who fell in love with a lazy, two-siding, self-serving conman.
  • Pro-Human Transhuman: She converted herself to a digital lifeform to keep helping people even after her body gave out.
  • Sanity Slippage: It's clear that losing Finn took a heavy toll on her psyche and dealing with a lethal virus that wiped out all of the helpers pretty much finished the job that started. All of her actions in the present are very realistically shown as not sane ones.
  • Totalitarian Utilitarian: She makes sure everyone on the Island is happy and safe, never letting them experience anything else in life. When many people show signs of wishing to leave, she tries to forcibly upload them into the computer so they can never leave.
  • Walking Spoiler: The fact Finn's mother is alive one of the first major twists of Islands. That she's the Big Bad of the arc is another.
  • Well-Intentioned Extremist: Her treatment of Finn aside, she also tries to keep the residents of the Islands safe by ensuring they never leave, but in doing so, she's crippled them developmentally and they have a difficult time making their own decisions and when she notices that they start to consider to leave the Islands, she tries to forcibly upload them into the computer.

Deities and Cosmic Beings

    Prismo 
https://static.tvtropes.org/pmwiki/pub/images/prismohj_60.png
Voiced by: Kumail Nanjiani

An all-powerful being who resides in the center of the multiverse. He's close friends with the Cosmic Owl, and has the power to grant wishes (with a twist) to anyone who reaches him, and alter the course of time itself at will. He is the product of an old man's dream, who keeps Prismo alive as long as he's asleep. However, the Lich kills his corporeal body in "Wake Up," ultimately killing Prismo as well. This did not stop him for long as he used a time paradox to return.


  • Adorkable: He's an extremely awkward, exceedingly nice guy.
  • Always Someone Better: Despite being a very powerful entity, Crossover reveals that he does have someone he needs to answer to if something major (like the Space-Time Continnum being destroyed) happens. Considering what Prismo can already do and given what it might take to piss Prismo's boss off, that says a frightening amount of how powerful they must be.
    Prismo: Now if that happens, my boss, let me repeat that, My. Boss. will hold me responsible. And by proxy, ya'll both will be in the dip too.
  • Ambiguously Gay: Prismo's pink-colored, he talks with a slight lisp, and he tends to chill in a hot tub with his guy-friends Jake and the Cosmic Owl. One topic of discussion in his room is him finding a girlfriend, which he awkwardly hems and haws over. He is also overjoyed when Jake casually claims he loves him.
  • Back from the Dead: He came up with a plan to bring himself back should he ever die, involving Finn and Jake. After Jake eats the last pickle Prismo made, he's sent to a weird place that seems to be outside time. A time double of Jake becomes the new dream host for Prismo.
  • Badass Adorable: He's unbelievably sweet, but he can alter reality and grant a potentially infinite number of wishes of any kind to anybody.
  • Be Careful What You Wish For: Prismo warns Jake that the wishes he grants all have an ironic twist to them, unless the request is specific enough that there is no way for it to backfire against the wisher. For example, when Finn wishes that the Lich never existed, the result is an alternate timeline where Jake is turned into a Lich-Dog hybrid.
  • Because You Were Nice to Me: A variant in that he admitted that part of the reason he helped Jake was that he greatly appreciated Jake actively being friendly to him as his only other friend seems to be the Cosmic Owl.
    • This extends to Finn as he was willing to risk himself to help Finn meet his dad.
  • Benevolent Genie: He's nice to an almost absurd degree. How nice? He straight out tells Jake not to waste his one wish on something stupid, like a sandwich, as well as explaining the fact that despite all of Prismo's power, he's still bound to giving wishes that have an "ironic twist". Heck, he even very heavily hints at the proper wish Jake should make to fix the whole mess made with Finn's wish.
  • Celestial Bureaucracy: "Crossover" reveals that he does have a boss that is implied to be much more powerful than him. He does mention that should the Space Time Continuum be destroyed, this boss would hold Prismo responsible (and apparently his associates/friends as well, considering Prismo tells Finn and Jake that by extension, they'd be in trouble too.)
  • Cheated Angle: He's almost always in profile but that seems to be by choice. He can turn his head despite his one-dimensional appearance.
  • Confirmed Bachelor: He tells Jake that he prefers the single life because relationships require too many compromises, using the question of coordinating dinner plans as an example. Jake disagrees and says that he needs to find Prismo a girlfriend, although Prismo seems more interested in Jake's company than anyone else's.
  • Could Say It, But...: He stretches this trope about as far as it goes.
  • The Cutie: GOOD LORD.
  • Didn't Think This Through: He tried to help Finn with meeting his father by having the heroes bring his mortal body into the chamber, with the Lich in the room the entire time.
  • Dream Apocalypse: The wish-granting genie is really the dream of the real and relatively normal man. Waking him up destroys the Wishmaster form, a crime worthy of the Citadel.
  • Honor Before Reason: He'll grant one wish to anybody who visits him no matter what it is — something the Lich used to his advantage.
  • Fatal Flaw: A bit of a different version as his flaw isn't necessarily "bad": arguably, he's too nice and trusting to people, possibly caused from his isolation from society and desire for friends. Allowing himself to temporarily die (and later permanently die) for someone he's only known for a little while exemplifies this.
  • Literal Genie: Played with. The wishes executed act like this in nature, but he admits that he doesn't do it deliberately because it is out of his control. Careful, specific wording can get around the Be Careful What You Wish For part, and although he granted The Lich's wish as it was, he's nice enough to help Jake to wish for the right thing and screw The Lich over.
  • Living Dream: He is an entity born from the dreams of an elderly man.
  • Living Shadow: He basically looks like a moving picture of a person on the floor and ceiling.
  • Nice Guy: Really nice. He seems like an all around great guy.
  • Oh, Crap!:
    • When the Lich is about to wake him up instead. It makes a certain amount of sense. The Wishmaster form would simply be incapacitated until his mortal form goes back to sleep in a thousand years, whereas if the Lich kills him, he's kinda screwed.
    • He does another one along with the Cosmic Owl when Betty says that she's going to rewrite history to prevent the Mushroom War from happening.
  • Our Genies Are Different: He grants wishes like genies would, but he's two-dimensional, is physically like a shadow and he lives at the center of the multiverse.
  • Overshadowed by Awesome: One of the most powerful beings on the show, but even he is powerless against GOLB, as he is unable to revive Margles and return Betty to normal.
  • Reality Warper: He grants wishes that can alter the course of history. However even his powers have limits — he can't bring back who were killed or assimilated by Golb. Both Magic Man and Simon went to him to try to get Margles and Betty back. Both times Prismo could only conjure a waste-paper basket-ball hoop.
  • Senseless Sacrifice: He allows Finn and Jake to wake up his human form, thus destroying his Wishmaster form. He did that so Finn could be sent to the Citadel to meet his human father... who was a manipulative Jerkass extraordinaire, and had no interest on Finn at all.
  • Time Master: Sort of. He uses wishes to allow people to navigate The Multiverse and stays in his own time-sealed room, but doesn't really ever leave it. His revival involved the use of a special room with a bizarre flow of time. Beyond creating a temporal duplicate of Jake to serve as Prismo's new 'host', Finn's time double becomes the Finn Sword.

    The Cosmic Owl 
https://static.tvtropes.org/pmwiki/pub/images/220px-owl_trans_2880.png
Voiced by: Jeremy Shada (What is Life), M. Emmet Walsh (all other appearances)

A mysterious and important entity in the land of Ooo, it appears to others in visions. It speaks in a Southern drawl initially and is a friend of Prismo.


  • Animalistic Abomination: A golden energy owl that appears in others consciousnesses and according to the Why-Wolves capable of devouring entire populations if they prove too numerous.
  • Cosmic Entity: The exact details of his powers aren't clear, but the people of Ooo regard him as a being of great importance.
  • Dream Walker: By entering people's dreams, he ensures that they come true, either literally or metaphorically.
  • Energy Being: It is an owl that is made out of yellowish cosmic energy.
  • Nice Job Breaking It, Hero!: In Hoots, he accidentally is present while Princess Bubblegum was dreaming about the Candy Kingdom's destruction, meaning he accidentally doomed the kingdom to an unknown catastrophe.
  • Oh, Crap!: He does one along with Prismo when Betty says that she's going to rewrite history to prevent the Mushroom War from happening.
  • Ominous Owl: Subverted; it's less of a malevolent force and is more of a natural force with some hobbies.
  • Only Friend: Prismo is his.
  • Physical God: Easily one of the most powerful entities in the series, but it does not directly interfere in the plot.
  • Reality Warper: To a certain extent. The way his powers work mean that, whatever the person is dreaming, as long as he is present, it will come true in the real world.
  • Verbal Tic: He hoots whenever he says a word with an "oo" sound.
  • Vocal Dissonance: One of the most ancient and powerful entities of the series, but it has a youthful, Southern drawl.

    Abraham Lincoln 
https://static.tvtropes.org/pmwiki/pub/images/e3ff371d0d29e2852c642a9cfc38d04e.png
Voiced by: Pendleton Ward

The King of Mars, and possibly the most powerful being in the Adventure Time universe, with the exception of Prismo.


  • Balancing Death's Books: He accidentally executed Jake thinking he was the Magic Man. He travels to the Eighth Dead World to bring him back, where he meets with Death. When Death refuses the payment of one penny, the King offers his immortality instead, killing him and turning him to stone (an exact replica of the Lincoln Memorial, in fact).
  • Early-Bird Cameo: Lincoln appeared as early as the 2008 short in a very... weird scene, and never came back until "Son of Mars" in 2012!
  • Friendless Background: As revealed in "Sons of Mars":
    Lincoln: "My judgement was less than the standard by which I judge my peers... of which I have none."
  • God-Emperor: He's the Martian King. He also appears to be a god.
  • Heroic Sacrifice: In order to bring Jake back from the dead, he offers Death his own immortality.
  • Large Ham: He can be ridiculously hammy.
  • My God, What Have I Done?: Upon Jake's death, who he thought was the Magic Man.
  • No Indoor Voice: Well, he's never really indoors.
  • Nonstandard Character Design: Really the only character in the entire series drawn with vaguely realistic features.
  • The Paragon: Finn refers to him as "the wisest, most honest superbeing of all time".

    Grob Gob Glob Grod 
https://static.tvtropes.org/pmwiki/pub/images/747f6797bb651c47ef942dcd0e606737.png
Voiced by: Melissa Villasenor (Grob), Tom Kenny (Gob), Tom Gammill (Glob), Miguel Ferrer (Grod)

A four-faced deity from Mars, and Magic Man's older brother.


  • Cain and Abel: The Abel to Magic Man's Cain.
  • Cosmic Entity: But like the Cosmic Owl, the extent of his power isn't clear.
  • Flaming Sword: His weapon of choice, which he used to defeat Orgalog.
  • God Is Dead: As of "Astral Plane." Subverted in "Normal Man" where it's revealed they're not dead, but have become orbiting entities around Earth/Ooo.
  • Guardian Entity: Was the guardian of Mars and, to a lesser extent, the rest of the solar system.
  • Heroic Sacrifice: Seemingly dies protecting the people of Mars from an incoming 'catalyst comet', which turns out to be Martin's spaceship
  • Multiple Head Case: He has four faces, each of which is a distinct being.
  • Offscreen Moment of Awesome: Implied to have protected Mars from a plethora of dangerous cosmic beings, including Orgalorg and GOLB.
  • Physical God: A literal god/cosmic being who physically fights to protect the worlds, and capable of striking down an Eldritch Abomination.
  • Pieces of God: His helmet fell down in You Forgot Your Floaties. Magic Man tried to use it and Betty's true human blood to take his power, but Betty took it instead. And Magic Man's. Also, his 4 heads now orbit the earth. He's still alive and sentient, but has chosen not to intervene anymore.
  • Starfish Alien: Even by Adventure Time standards, he's one of the strangest-looking beings in the show.

    Death 
https://static.tvtropes.org/pmwiki/pub/images/death_adventure_time_3986.png
Voiced by: Miguel Ferrer

Ruler of the Land of the Dead, Death has power over the deceased and is able to raise them whenever he wills it. Best friends with Peppermint Butler.


  • Affably Evil: Despite being an overall nice guy, "The Gift That Reaps Giving" hints that Death will not back down from doing despicable things if it gets him what he wants. In that short, he wants to gift a mixtape to his girlfriend, and decides that the easiest way to acquire one is by murdering an innocent child who has it.
  • Deal with the Devil: In "Sons of Mars", Death agrees to resurrect Jake in exchange for Abraham Lincoln's immortality. It's also implied that he once revived someone for Lincoln in exchange for a penny.
  • Dem Bones: He appears as an anthropomorphic skeletal equine.
  • Don't Fear the Reaper: When we actually see him doing his job as opposed to dealing with people invading his territory and trying to resurrect people, Death is rather friendly. He prepares a special trip for Simon with music and everything and both he and his target consider it a Mercy Kill. When said target decides to let the attempt to save him go on anyways, Death steps back to see what happens.
  • Intangibility: Apparently you can't kick him if your brain is stupid. More seriously, Word of God states that even the Lich hasn't beaten him, merely cheated him.
  • Kiss of Death: Subverted. A kiss from Death gives you your memory back.
  • Light 'em Up: Lives in a castle of light. This doesn't affect his morality much.
  • Man in White: Is decked out in all white clothing.
  • Nice Hat: Rocks a cowboy hat.
  • Nice Guy: When not angered, he's a pretty nice guy surprisingly. This is particularly true with his girlfriend, Life, who he tries his best to get a birthday present for.
  • Rock Me, Asmodeus!: For a skeleton, he's quite skilled with a guitar.
  • Serious Business: Musical battles.
    Death: Those the rules of the Land of the Dead; lose a music battle, lose your life.
  • Stealth Pun: He plays Death Metal in a musical battle.

The personification of life. Death's girlfriend. Appears in the digital short "The Gift That Reaps Giving".


    The Catalyst Comet 
Voiced by: Tig Notaro

The otherworldly force that causes major, and often dangerous, changes in the world whenever it passes. In "The Comet", it is revealed to be sentient and actually rather benevolent.


  • Alien Geometry: It's really a hollowed-out sphere with 3 eyes.
  • Arc Villain: Sorta one for season 6. Subverted when it's revealed to not really be evil.
  • Ascended to a Higher Plane of Existence: Its offer to Finn, which he declines. Martin is eager to take it up, though.
  • Comet of Doom: Causes catastrophic events whenever it passes. It turns out that it isn't a malevolent force, but rather just an agent of change.
  • Long List: Tells Finn about the attributes and events in his life while bringing up its cosmic offer, and when Finn points out that it's just droning on, the comet defensively states that it's a long list.
  • Purple Is Powerful: It can alter the course of reality itself!
  • Walking Spoiler: Due to its sentience and intentions.

    The Multiverse 
https://static.tvtropes.org/pmwiki/pub/images/the_cosmic_imagiation.jpg

The sentient totality of all universes across existence.


  • All There in the Manual: It is only briefly alluded as sentient during the series itself by Finn, who "prays" to it during the events of The Comet, but its nature and mechanics are only explained by the spin-off book "The Enchiridion"
  • Dream Land: "The Sleepers" are capable of dreaming entire universes into existence. The Enchiridion itself implies The Multiverse is just a dream of a mysterious entity known as "The Reader".
  • Gods Need Prayer Badly: Well, perception in this case. Basically, the Multiverse is a reality formed by the collective consciousness of all living things in existence, and if there is no one left to observe it, it simply ceases to exist. Somewhat Averted, as the Enchiridion states the Multiverse can potentially return to existence, in some "new, unknown way", even after ceasing to be in its entirety.
    ''The Multiverse is a consensus reality shared by the Minds of all sentient beings. If they were to die, the Multiverse, as such, would suddenly blink out of existence, vanish, be no more."
  • Our Gods Are Different: It is literally an infinite, self-aware and self-born collection of universes and dimensions.
  • Power Source: It is the source of all Magic across all of existence, as Mages can use their minds to alter reality by tapping into The Multiverse's powers, achieving the capability of using Magic.
  • Sentient Cosmic Force: A sentient multiverse.
  • The Multiverse: It's Exactly What It Says on the Tin.

Other Inhabitants of Outer Space and Alternate Dimensions

    The Shape-shifter/Warren Ampersand 
https://static.tvtropes.org/pmwiki/pub/images/62d18f81fa96cd2875e5ed0e048c2540.png
Voiced by: John DiMaggio, Dave Foley ("The First Investigation" and "Jake the Starchild")

A strange monster that Joshua and Margaret encounter during one of their investigations. Has only appeared in "Joshua and Margaret Investigates" so far until his return in "The First Investigation" and "Jake the Starchild".


  • Abusive Parents: Manages to be even worse than Martin and Hunson combined.
  • Affably Evil: He’s rather friendly and personable... for a guy who only reproduces so that he can drain his offspring’s lives later on.
  • Aliens Are Bastards: Threatens a pregnant lady, implants its egg into her husband, and chuckles wickedly at the end of it all before going home... it's the embodiment of this trope, albeit one (somewhat) toned down. And then there's the reveal about what he did to his own children.
  • Alien Blood: It bleeds bright green blood after Margaret pricks it with a pin.
  • Ascended to a Higher Plane of Existence: Played with. He accepts his impending doom via black hole on the grounds that it will lead to this, but it's not clear if that's what will actually happen.
  • Disappeared Dad: Assuming gender even applies, it's either this or Missing Mom to its child Jake the dog. Jake isn't even aware that he isn't Margaret's biological child since his parents never told him about their encounter with the Shape-shifter. It's eventually revealed to be male in "Jake the Starchild".
  • Eldritch Abomination: Assuming the last form it takes in the episode is its true form, it's one of the most bizarre beings in the series.
  • Face Death with Dignity: When it becomes clear he's going to get sucked into a black hole, he swiftly becomes eager to, noting that he has done as much as he can with a physical body, and is interested by the idea of a greater, more cosmic existence — which he thinks the black hole can provide. Then he lets himself die without resistance.
  • Face Full of Alien Wing-Wong: Inflicted this on Joshua, with Jake being the result. That and several other individuals.
  • Killed Off for Real: Jake throws him inside a black hole after he decides to suck the life force of Jake's kids.
  • Offing the Offspring: By sucking their life force.
  • Out-Gambitted: Once Jake realizes that Warren is tricking him, he swiftly gets the upper hand over the alien with a simple trick.
  • Pet the Dog: Admits he actually feels something for Jake, and, post-reveal, uses his stretchy powers to try to entertain and comfort him.
  • Superpowerful Genetics: Passed on its powers and some of its physical traits to its son Jake and his children.
  • Suspiciously Similar Substitute: Holds a number of striking similarities to Martin, including being a Disappeared Dad, being profoundly selfish but still having a Pet the Dog moment related to his kid, being heavily associated with outer space, being skilled at deception, and eventually choosing to leave behind their prior life to experience a more cosmic existence.
  • Vampiric Draining: Drained the life out of his offspring in order to keep himself alive through a special belt.
  • Vocal Dissonance: When we finally hear it speak it has a high pitched nerdy sounding voice despite its size and alien appearance.
  • Voluntary Shapeshifter: Turns into many different forms in the only episode it appeared in so far, such as a baby, humanoids, a cat, an owl and many other unknown forms. He can also create an entire city and actual people on an abandoned planet.
  • Walking Spoiler: He's Jake's parent, and wants to drain his life essence like he has done with his other offspring.
  • Wounded Gazelle Gambit: Took on the form of a baby when Margaret had it cornered. Margaret (apologetically) punched it out anyway.

    Space Moth 
A gigantic... well, moth that provided milk for the koala people before Martin hijacked it.

    Martin 2 
The leader of the koala people that Martin takes a liking to.
  • Morality Pet: Averted. While Martin seems fond of him, even giving him a nickname, he leaves Martin 2 high and dry when it turns out he was the one the guards were after the whole time.
  • Older Than They Look: He turns out to be an old man, which we don't find out until a Gross-Up Close-Up of him.
  • Pintsize Powerhouse: He is able to hold his own against several guards many times his size.

Other Characters

    The Snail 
https://static.tvtropes.org/pmwiki/pub/images/Snail_from_AT_9735.PNG
Voiced by: Pendleton Ward

A snail who can be seen waving at the audience in every episode. His only notable role in any episode was being mind-controlled by the Lich into releasing it.


  • Demonic Possession: He spends two whole seasons being possessed by The Lich. He was finally released when The Lich chose to Body Surf into Billy.
  • Demoted to Extra: He was always just an extra in the series, but as soon as he releases the Lich in season 4, his importance in the plot completely evaporates.
  • Evil Sounds Deep: At the end of "In Your Footsteps" the possessed snails speaks in a deep voice.
  • Freeze-Frame Bonus: Once an Episode, he can be seen in the background waving.
  • Nice Job Breaking It, Hero!: Releasing the Lich.
  • Once an Episode: Because of this, he's actually appeared in more episodes than Princess Bubblegum or the Ice King.
  • O.O.C. Is Serious Business: He usually waves in every episode to the viewer, regardless of being possessed or not. When he shows up in "Gumbaldia", he simply watches Bubblegum screams in anger at Gumbald before declaring war against him and his city, showing that things will get serious during the finale.
  • Orwellian Retcon: He was not originally in two episodes: "Trouble in Lumpy Space" and "Blood Under the Skin". But then he was later added in to both episodes before reruns aired.
  • Unwitting Instigator of Doom: Was the reason the Lich was able to escape in the first place; he happened to hitch a ride in Finn's backpack when Finn and Jake were taken by Princess Bubblegum to the tree where the Lich was imprisoned. As soon as he crawled out, the snail was then possessed by the Lich into shattering the prison of amber and freeing him.

    Morty Rogers 
https://static.tvtropes.org/pmwiki/pub/images/morty_roger.png
Voiced by: Ron Livingston

A traveling puppeteer, who it turns out isn't really using puppets, but a couple of imps who have possessed his ears.


  • The Barnum: He's not looking for customers to scam money out of, but rather, an unwitting patsy to pass off his curse to via moon ritual.
  • My God, What Have I Done?: He realizes how much he misses Chips and Ice Cream after being free of them for a day and running into them. He tries to secretly redo the ritual from outside the window of Finn and Jake's house, except that it was all a Batman Gambit on BMO's part to free the two imps.

    James Baxter 
https://static.tvtropes.org/pmwiki/pub/images/james_baxter.png

  • Fun Personified: He spends his time performing for other people (read: running around balancing on top of an inflatable ball), taking their worries away. Deconstructed in "Horse and Ball". After his ball pops, he becomes depressed because he feels he no longer has a purpose. He then realizes that he has spent so much time making others happy he had no time to make himself happy. When Jake recovers a whole bunch of balls for him, he rejects them and instead dances for the pure joy of it.
  • Heroic B.S.O.D.: Undergoes one in "Horse and Ball" after his ball pops.
  • Line-of-Sight Name: He comes up with his name when he sees a box labeled "Games" and a sign reading "Bookstore".

    Phlannel Boxingday 
https://static.tvtropes.org/pmwiki/pub/images/77584b2b88ca4cb7fcbe8bb82a5bbaeb.png
Voiced by: Creed Bratton

A monster hunter who rides a cloud around the sky. He rescues Lemonhope from the desert and later inspires him to free the Lemon Children. Might be a bubblegum man, and implied to have a connection to Princess Bubblegum, with the same initials, an instance of Techno Babble and fluency in German, and being bound by the same pacts and treaties that prevent Bubblegum from interfering with Castle Lemongrab. It's also very heavily implied that he is actually Bubblegum in disguise.


  • Cool Old Guy: Flies around in a cloud-cart, killing treasure-eating monsters for their treasure and harvesting black diamonds for love potions.
  • Foil: To Princess Bubblegum. She raises Lemonhope under the strict belief that he is required to free the lemon people and take over as ruler while Phlannel encourages him to do what he wants and live as a free spirit.
  • Order Versus Chaos: He offers to Lemonhope the life of a chaotic free spirit in contrast to Princess Bubblegum's forcing him to become a martyr for his people.
  • Red Oni, Blue Oni: A passionate wanderer who values freedom above all else compared to the strict and pragmatic Princess Bubblegum who believes the safety of the people outweighs the happiness of the people.
