BMO (phonetically spelled Beemo) is Finn and Jake's living video game console, portable electrical outlet, music player, roommate, camera, alarm clock, toaster, flashlight, strobe light, skateboarder, friend, soccer player, video editor, video player, tape player and chef. They make their appearance in the title scene of the Theme Song of every episode of Adventure Time, just as Finn and Jake pound their fists together. BMO is characterized as a loyal, trusting, and helpful friend who is protective of Finn and Jake.


When Patrick McHale was preparing a short animation for Cartoon Network, he had a robot character named Raye for that purpose, which Pendleton Ward and McHale loved.[1][2] However, after Adventure Time got picked up, Raye was redesigned and became BMO.[1]

BMO's voice was originally to be similar to a computer-synthesized voice, but as a result of a suggestion from Ward, Niki Yang's natural voice (also voiced Lady Rainicorn) with some adjustments became the voice of BMO.[3] As a result, BMO speaks in a Korean accent. Earlier voice actors for the character included Dee Bradley Baker (voice of Cinnamon Bun) and Thurop Van Orman (voice of the Tree Witch).


S2e16 Beemo

BMO is not amused.

BMO looks like a half-Macintosh half-Game Boy Color with Atari 2600 controllers. They also shares some traits with a Vectrex.

BMO is a medium-sized teal/blue-green handheld gaming device, sometimes appearing with one or two controllers attached to them. When they are not being played they have an 8-bit face.

BMO's front includes an arrow pad, a floppy disk slot, multiple different shape buttons, two controller sockets, and of course the face, or screen. There is also a compartment with a red button hidden underneath the yellow D-pad. His software is somewhat similar to a Macintosh computer, as seen in "Be More" with a graphical interface and drag-and-drop file manager.

On BMO's sides, the letters "BMO" are printed, indicating their name. BMO's arms emerge from the center of the "O." There are also what appear to be holes for speakers at the tops of their sides.

BMO's back contains a battery compartment which holds 2 AA batteries, first seen in "BMO Lost." Normally, the battery door is shown attached with 4 screws. However, in "BMO Lost," it is shown with a tab at the top instead. There is also a slot which can be used for playing video tapes as seen in "Holly Jolly Secrets Part I."

BMO's default controllers highly resemble Atari 2600 game console controllers, as they feature a single joystick and one red button. BMO's controller in "Too Young" slightly resembles a Sega Genesis controller for its button layout and handling design. An interesting note about this is that, in reality, both the Atari 2600 and the Sega Genesis have share an identical input device. This means that both controllers can be hooked up to the same device without issue.

BMO is sometimes seen with two slots to plug in controllers and sometimes with a compartment on that spot that opens up to where controllers can be plugged in.

S5e28 BMO's innards

Inside BMO

Inside BMO, there is a gold heart with a face, as shown in "Be More." Pinned to the heart is a gold medal. Next to the heart is a small scroll tied with a red ribbon. This is likely a reference to the gifts given to the Scarecrow, Tin Man, and Cowardly Lion in the 1939 film The Wizard of Oz, symbolizing brains, courage, and heart.

Personality and character traits

According to Finn, "BMO does weird junk when no one is around." He proves this in "Five Short Graybles," where BMO talks to their reflection in the mirror, naming it Football, and pretended to be a "little living boy." In "BMO Noire," BMO acts out a film noir fantasy complete with giving names, voices and dialogue to a number of animals and an inanimate object in the house. The way they interacts with their reflection in "Five Short Graybles," as well as the animals in "BMO Noire," is evidence that BMO may suffer from dissociative identity disorder, otherwise known as a multiple personality disorder. This causes BMO to act like completely different people, and have them communicate with each other.

BMO claims to not have emotions, but this is not true. In "Donny," BMO says, "I am incapable of emotion, but you are making me chafed!" They show signs of annoyance in "Too Young" when Jake uses BMO as an ottoman. BMO demonstrates independence when they refuse to turn down their music even after Jake tells them to. Although they are both robots, BMO refuses Neptr's request to hang out more in "BMO Noire" by saying, "No, Neptr, I am not like you." In "Davey," BMO cries while Finn shaves his head to disguise himself as Davey.

BMO is very protective of Finn and Jake. In "Incendium," BMO says, "If anyone tries to hurt Finn, I will kill them." In "Guardians of Sunshine," BMO refuses to let Finn and Jake enter the video game world saying, "No! It's a far too dangerous, incredible adventure for you! That's final!"

BMO often acts to maintain the harmony of friendship between Finn and Jake. In "Video Makers," they edit the film Finn and Jake make in a way to resolve their dispute over the film's artistic direction, even composing a song for them. In "Card Wars," they refuse to "play such games with Jake" because Jake cannot deal with losing. When Finn asks BMO for advice on Jake's attitude, they recommended that Finn play to lose.

BMO likes a number of games and even a few sports. BMO has been seen playing their video games by themself in "BMO Noire." They have also been seen skateboarding in "Card Wars" and "Time Sandwich," and they once had to be picked up from soccer in the episode "In Your Footsteps."

BMO likes scrambled eggs, as shown in "Her Parents," and hot chocolate, as shown in "Video Makers" and "Holly Jolly Secrets Part II." In "Five More Short Graybles," BMO is shown to "drink" tea while teaching Football manners. There, BMO attempts drinking the tea with their pinkie finger up, but Football does not. BMO drank again and again, resulting the electrocution of themself. All of this shows that even though BMO cannot drink things, they still try while pretending to be real. They has never been seen actually consuming food. Despite this, BMO can cook, and makes dinner for Finn and Jake in "Little Dude." BMO reveals in "The Creeps" that they enjoy taking nice pictures. BMO also likes to dance.

BMO is shown to be ticklish. This is seen when they giggle after Princess Bubblegum plays their circuits like a keyboard in "What Was Missing." They also react to being tickled by a feather while sleeping in "Guardians of Sunshine" and when they laugh and wriggle as their foot is being nibbled by a bear in "In Your Footsteps."

BMO's most prized possession is their controller, as it is one of the objects the Door Lord steals in "What Was Missing." In "Furniture and Meat," BMO is shown to like pretend-sword fighting with Neptr at the start of the episode.


BMO's gender pronouns vary depending on who is speaking or what make-believe scenario BMO is playing out. Characters refer to BMO using masculine and feminine pronouns. For instance, in "Conquest of Cuteness" Finn calls BMO "M'lady." In "Rainy Day Daydream," he refers to BMO using "he." In "Guardians of Sunshine," Sleepy Sam uses "he" when talking about BMO. Jake has also called BMO a "he" in "Return to the Nightosphere" as well as "The Creeps." In "Five Short Graybles," Cuber refers to BMO using the masculine pronoun "he": "BMO saw his reflection."

BMO will sometimes play pretend games in which it assumes a specific gender, such as calling itself a "little living boy" in "Davey."

In the "Little Did You Know" DVD set, BMO's profile states that "he" is a good listener.

In "Five Short Graybles" BMO's mirrored persona, Football, claims it is "a real baby girl" in "Five More Short Graybles." Throughout the episode "BMO Noire," BMO role-plays as a hard-boiled, masculine detective; though it is noteworthy that the title of the episode treats "BMO" as a feminine noun by using "noire" instead of "noir."

In "Fionna and Cake," BMO is briefly seen in the tree house with no noticeable differences in design (aside from its controller), as opposed to the other characters who have all been gender-swapped. This is because BMO flips their gender as it is and is gender neutral.

In "James Baxter the Horse," BMO sings "BMO's Pregnant Song." about how she was asked by an electric present to hold a human incarnation of a baby. BMO does not understand the reproduction of humans because Finn is one of the few humans left after the mushroom war.

In "Football," BMO is referred to by Jake as a boy when he says "put that traffic cone back on your head young man." BMO's alternate persona "Football" is referred to as female in this episode while BMO is referred to as male.


One of the many functions BMO has is the ability to send users into a video game through their main-brain-game-frame by pressing a button located under his d-pad. By doing this, users are able to play the game in a virtual reality where they can physically complete objectives with the possibility of actual death. This process can also be reversed and things within the game can be transported into the real world. BMO also possesses several attachments which allows them to perform various tasks aside from video games. This includes the ability to put up a holographic display of their screen to support a wider audience. BMO also possesses editing software for film creation, but they have personal choice regarding the footage that is actually used to make up their films.

In "Conquest of Cuteness," BMO reveals a built-in camera with the flash emerging from the top left of their head while their screen works as the lens. In "The Creeps," BMO uses a built-in flash device that helps them take pictures, as well as the ability print pictures and documents out their rear. BMO can function as an alarm clock, which is set to Finn's bath time, and is seen in "Holly Jolly Secrets Part I." In this episode, BMO demonstrates that they can insert VHS tapes into their back, and display the video on their screen. In "Incendium," BMO uses their BMO Cam, which records live video feed. In "Daddy's Little Monster" and "What Was Missing," BMO is shown to be able to charge or power electronic devices such as Jake's video phone and a noodle cooker. However, this function appears to exhaust BMO, likely because they use their own energy to charge and power the devices.

In the episode "Hug Wolf," BMO is shown to have a blinding "Strobe Light Mode." BMO is also capable of performing the devastating Combo Move from the game "Guardians of Sunshine" in real life. The episode, "In Your Footsteps," reveals that BMO plays soccer, and shows BMO wearing a red jersey, red cleats, and while covered in dirt and mud. In "Card Wars" and "Time Sandwich," BMO demonstrates their skill in skateboarding and performs various tricks and jumps. BMO is also able to perform a sneak attack known as the BMO Chop, which they state to a victim of the strike, "If this were a real attack, you would be dead." In "Burning Low," it is seen that BMO can connect with other computers or devices for live video chat. 

BMO is shown to know how to use a bow and arrows in "Furniture and Meat" when they shoot the pipe of hot melted gold away from Finn and Jake, killing a guard and saving Finn and Jake. 


Finn and Jake

BMO lives in the Tree Fort along with Finn and Jake and is used as their game console and many other things. They are loyal to Finn, as they said they will kill anyone who tries to hurt Finn, as seen in "Incendium." Also seen in "Video Makers," BMO does not side with either Finn or Jake. BMO cries when Finn shaves off his hair to be "Davey," sobbing that his "beauty" is destroyed.


It seems that Marceline and BMO have a fairly friendly relationship, as she is seen playing her in "Evicted!" and commenting on how she thinks they're cute. Also in "What Was Missing," Marceline assists BMO and proceeds to call them "baby."


In "BMO Noire," BMO mentions that Lorraine is "red hot like pizza supper." Furthermore, Lorraine also mentions that the loot is in their "secret grown up kissing spot" at the end of the episode, thus implying that at one point in time they had a relationship. This might be taken as an indication that BMO finds Lorraine attractive. However, the entire episode hints that the plot of "BMO Noire" is nothing but a play created by BMO's imagination. So, it is possible that their relationship exists only in BMO's fantasy. It is also possible that BMO is not attracted to Lorraine and the attraction/relationship is fictional like the detective persona that BMO created for themself.

Air (Bubble)

Air (Bubble) is a pal that BMO met in the episode "BMO Lost." After an adventure to help BMO get home through hard times with a baby named Sparkle (whom BMO had named Ricky), Bubble confesses that it is in love with BMO and proposes they get married, which BMO gladly accepts. Sadly, Jake decided to pop the bubble, making it now Air. BMO cries thinking that their love is lost but then air speaks to BMO and tells them that he will always love them. BMO claps and seems to have forgotten the previous tragedy, after some time it would seem their relationship has been subsided when BMO wonders about growing and asks him, but gets no reply.


Sparkle (Ricky) appears in the episode "BMO Lost." This baby was lost and separated from his mother, so BMO decides to name the baby "Ricky" and bring him along on the adventure of all three characters, BMO, Air (Bubble), and Sparkle (Ricky), trying to find their home. Sparkle is later rediscovered by his mother and taken to his rightful home.
S5e28 Moe and BMO

BMO meets his maker.


Moe is BMO's creator, as shown in the episode "Be More." He created BMO because he wanted BMO to take care of his son, but he "never ended up dating any women." Moe created BMO so it could "B MOre." Unlike a number of artificially created characters in the series (such as Lemongrab or Goliad), BMO is shown to be on good terms with his creator. The two embraced shortly after Moe fixed BMO's software, the former then revealing his creation's family in an underground civilization of happy MOs. 


It appears that Neptr and BMO have a fairly good relationship, and that Neptr is happy to be around them. In "BMO Noire," Neptr suggests that the two should "hang out more." BMO declines, saying, "I'm not like you." This suggests that they feel coldly towards Neptr, and perhaps superior, even with their similarities in that both of them are machines. In "Furniture and Meat," BMO and Neptr are seen playing "Robin Hood" together, with BMO as Robin Hood and Neptr as the Sheriff of Nottingham. When Neptr asks if he can be Friar Tuck, BMO says no, then draws on their face with a marker. Once again, this shows that BMO is not always kind to Neptr. However, in "Sad Face," they seem to be friends.


S4e2 BMO looking in mirror

Football in BMO's reflection

Football (often misinterpreted as "Fupo" due to BMO's thick accent) is the name used by BMO when talking to themself in the mirror. During this scene, BMO is a "little living boy" while Football is a robot as seen in "Five Short Graybles." BMO purposefully only plays with Football when Finn and Jake are not around. In "Five More Short Graybles," Football claims to be a "real baby girl," and BMO tries to teach Football manners. In "Football", Football transfers to the real world by the agreement by BMO. Football likes the real world and doesn't want to go back to Football's world. This makes BMO upset. Even though BMO has been mean with Football, BMO still loves Football.


BMO and AMO are not on the best standards, even to the point of violence. BMO's not friends with AMO.

Episodes featured

BMO makes a cameo in the episode "Evicted!" being played by Marceline while Finn and Jake are house-hunting. In "Business Time," Finn and Jake play Adventure Master and Pro Football 1861 on them. They are later seen in the episode "My Two Favorite People." In "The Witch's Garden," Finn plays a game as he asks Jake how he got his magical powers. BMO also appears in "What is Life?" when Jake throws a garbage bag of butter on Finn, and in the episode "Donny," one of their controllers is smashed in half. BMO claims to not have emotions, but Donny angers him by breaking a controller and throwing it at BMO. In "Rainy Day Daydream," they show a bored Finn and Jake a new game, "Conversation Parade."

BMO appears again in "Slow Love" where they act like a rebellious kid, refusing to turn down their music when Jake tells them. BMO is then hit with a newspaper and told to have a timeout at a corner. BMO was then pummeled and battered when Snorlock started dancing with lady snails while the tree house was on its back, but was apparently unharmed and returned to play music at the end of the episode when Snorlock was kissing his new girlfriend.

In "Power Animal," BMO unintentionally distracted Jake with songs. They were later eating lunch together and Jake told BMO to hold his sandwich. BMO later fixes the well overhang that leads to the gnome's underground hideout that Jake had demolished while entering.

In "Guardians of Sunshine," it is revealed BMO has a button hidden under their control pad that allows people to be transported into one of their games. However, they do not allow Finn and Jake inside them, claiming it's too dangerous of an adventure. Despite his warning, Finn and Jake trick BMO by tickling them with a feather until they press their button while they are sleeping. BMO later appears when Finn and Jake exit the game. While trying to tear a bomba out of the game's interface, they make a hole in it. BMO is then attacked by Sleepy Sam, Hunny Bunny, and Bouncy Bee for imprisoning them in the game. After Finn performs a combo move and destroys the monsters, BMO scolds them for going into the game and starts doing the combo move on them.

In "Video Makers," BMO serves as Finn and Jake's cameraman, filming random pieces of footage around the Land of Ooo with a video camera attached to their head at Finn and Jake's request, before they decide to make a real movie and argue about what kind of movie it will be. BMO, as their cameraman, witnesses their arguments, and instead of using the footage they captured for the movie, they make their own animation while singing a song about how Finn and Jake should forget their argument and make up. At the end of the episode, BMO says Jake's favorite line throughout the episode, "Check, please!"

In the episode "Conquest of Cuteness," Finn and Jake call BMO over to get a camera to take pictures of the Cuties, but it turns out BMO is a camera, even though in the episode "Video Makers," BMO has a video camera strapped to their head. It is possible, however, that BMO's built-in camera only takes pictures.

In the episode "Too Young," BMO asks about Finn's date with Princess Bubblegum and does not tell Jake where the key is to the Wizard Tower in the video game. When Jake is trying to cheer Finn up when Princess Bubblegum jokingly "dumped" him, Jake puts both of his feet on BMO, using them as an ottoman, which annoys BMO.

BMO makes an appearance in "Fionna and Cake" in the opening and is later seen being played by Cake. Their appearance remains the same, supporting that they have no gender.

In the episode "What Was Missing," BMO has their controller stolen by the Door Lord and serves as a musical instrument during "I'm Just Your Problem." Marceline also used them to power a stove, showing that they are also a portable electrical outlet.

In the episode "The Creeps," they were in the mystery party when Finn and Jake came in the house. Their mystery name was Professor Pants. After the light went down and returned, BMO and Jake went to the basement to get some candles, but BMO was "killed" by the "ghost." At the end of the episode, they are discovered by Finn in Lady Rainicorn's body, being in the prank with Jake and the others.

BMO appears in "Incendium" watching over Finn while Jake was looking for another love interest for Finn.

BMO reappears in "Five Short Graybles" under the "Sight" segment of the episode (see article subsection "Football" below for more info).

BMO makes another appearance in "Beyond this Earthly Realm" when they amusr Finn with its fart noises. They also play Finn's favorite song, "Three Baby Spiders"; a seeming nursery rhyme, BMO plays the song in a futile attempt to bring Finn back from the Spirit World.

In "Card Wars," BMO warns Finn about Jake taking the game too seriously.

BMO makes an appearance in "Burning Low." First, they tell Jake that he is late for a video chat with President Porpoise, and later on Jake plays an unknown game involving a rectangle punching, kicking, and jumping.

In "BMO Noire," BMO goes undercover as a detective to search for Finn's missing sock. The episode is narrated by BMO and is in black and white, similar to a 1940s- and '50s-era crime film. This is BMO's first central role.

BMO appears in "James Baxter the Horse" singing "BMO's Pregnant Song" and helps Finn and Jake create their routine.

BMO is once again the central character in "BMO Lost," where they are abducted by an eagle and has to find their way home through a forest. During their adventure, they meet Bubble and the baby Sparkle, whom they try to help. Bubble ends up proposing to BMO but is popped by Jake.

In "Be More," BMO's purpose as "being more" is revealed, and they reunite with their father, Moe. BMO deletes some of their files for fun, but accidentally deletes their core system drivers. Finn and Jake discover where they were created when BMO tells them that they need new drivers. When Moe tells Finn and Jake BMO's story, CMO approaches and gives the core system to Moe, who repairs BMO without erasing their memory.

See: BMO/Quotes


  • BMO's voice was originally much deeper. Pendleton Ward revealed this on the animatic for "Rainy Day Daydream" on the Adventure Time: The Complete First Season DVD box set, which is also heard in the animatic.[4]
  • He wants very much to understand living beings, one example of that is in "All's Well That Rats Swell," when he thinks that Finn will become young forever if he plucks his beard.
    • In the same episode he demonstrates again his ignorance to the living beings, asking Finn kissing to his wound that made a rat in his hand, eventually leaving Finn sick.
    • In the same episode he seems not to know that not all animals are intelligent for wanting to make a thumb wrestling with a rat and eventually being bitten.
  • BMO can display emoticons on his screen (Such as D: and -_-), as seen in "What Was Missing."
  • BMO's screen can be used as a touch screen for at least one function, Jake demonstrated this in "James Baxter the Horse."
  • When BMO lowers their volume in "Holly Jolly Secrets Part I," they put their volume on the lowest setting but could still talk.
  • Many of BMO's games are knock-offs of the games for the Atari 2600 video game platform.
  • According to "What Was Missing," BMO's prized possession is their controller.
  • In the special features section of the It Came from the Nightosphere DVD, BMO's age is shown as "VER. 2600," and their species is "110 VOLT/60 HERTZ SYSTEM." BMO is also referred to as "he."
  • During Pendleton Ward's interview with Hot Topic, he stated BMO is his favorite character.[5]
  • BMO supposedly has "butt circuits" as mentioned in "BMO Lost." 
  • As seen in "James Baxter the Horse" and "Davey," BMO can cry, and their tears are apparently triangles.
  • It was revealed in "Shh!" that BMO's favorite song is No Wonder I by the band LAKE.
  • BMO is completely the same in the Fionna and Cake version.
  • BMO is Moe's favorite robot.
  • BMO literally has a heart of gold, as seen in "Be More."
  • It was revealed that in the episode "In Your Footsteps" BMO plays soccer.
  • BMO's BMO chop memory (which originated from "Card Wars") was deleted in "Be More," implying that we may never see it again.
  • BMO can do a kickflip on their skateboard as shown in "Card Wars."
  • BMO loves many things about weddings, including weddings in general and flowers.
  • BMO loves love.

Cultural references

  • In "BMO Lost," the crack on BMO's screen can sometimes be seen separating their face into two distinctly colored halves and forming a pointed 'nose.' This is very similar to the iconic Happy Mac from Mac OS 8 and is possibly another one of BMO's many Apple references.
  • Their start-up sound is the same as the Apple II computer.
  • As seen in "Be More," BMO runs a combination of Windows and Mac operating systems.
  • The heart, medal, and scroll inside BMO may be a reference to the heart-shaped watch, medal of courage, and diploma presented to the Tin Man, Cowardly Lion, and Scarecrow at the end of The Wizard of Oz.
  • BMO's behavior when they are alone could be a reference to Isaacs Asimov's "Catch that Rabbit," in which a robot acts strangely when it thinks it is not being watched.

Storyline analysis

  • Even though BMO has buttons, they are rarely used to play video games. Instead, the buttons are used for various other functions, such as sucking things into BMO's mainframe or shutting off BMO's alarm. Finn and Jake mostly use controllers when playing games. In "Evicted!," Marceline seems to be trying to play a game using BMO themself, but their face is still being displayed.


  • In "What Was Missing," Princess Bubblegum takes off BMO's template. BMO yells, "My face!" implying that his template is their face, not the screen. However, when their screen is cracked in "BMO Lost," they also refer to that as their face. It is very possible, though, that the entire front of BMO, which would be the template and the screen, is their face.
  • Also, in "Video Makers," BMO is taller, their face is longer and their body is thinner, although this might just be an animation error.
