BMO (also spelled as Beemo) is Finn and Jake's living video game robot, console, camera, music player, soccer player and etc. He made an appearance in the Theme Song of Adventure Time. He is very protective of Finn seen in the episode Incedium.


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

BMO is a medium-size green handheld gaming device, sometimes appearing with one or two controllers attached to it. When it's not being played it has an 8-bit face. The letters "BMO" are printed on its sides, indicating its name. BMO's left arm emerges from the "O."

BMO's default controllers highly resemble the Atari 2600 game console controllers, as they both only have a 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 an Atari 2600 and a Sega Genesis controller have the same controller input device in reality, meaning 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.


It is confirmed that BMO has no gender since he is a robot. BMO looks like a he because in the episode Rainy Day Dream. But in the episode Conquest of Cuteness Finn called him a lady. 

He is seen in the episode Fionna and Cake where it was the episode of the gender-swapped characters. 


He is a loyal, trusting and helpful. He has a strong british accent. 

According to Finn, "BMO does weird junk when no one is around;" As he proved in "Five Short Grayables" where BMO talked to a mirror reflection named 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 one inanimate object, in the house.

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!" It got annoyed in "Too Young" when Jake used BMO as an ottoman. BMO acted independently in "Slow Love" when BMO refused to turn down its music after Jake tells it to. Though 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."

BMO is very protective of Finn and Jake. In "Incendium" BMO said, "If anyone tries to hurt Finn, I will kill them," and in "Guardians of Sunshine" BMO refused 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 acts to keep the harmony of friendship between Finn and Jake. In "Video Makers" it edits the film Finn and Jake make in a way to resolve their dispute over artistic direction, even composing a song. In "Card Wars" it refuses to "play such games with Jake," because Jake can't handle losing. When Finn asked for advice on Jake's attitude, BMO recommended that Finn play to lose.

BMO likes a number of games and even a few sports. BMO has been seen playing its video games by itself in "BMO Noire." BMO also has been seen skateboarding in "Card Wars" and 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 II," though it has never been seen actually consuming food. BMO reveals in "The Creeps" that it enjoys taking nice pictures. BMO also likes to dance.

BMO is ticklish. This is shown when it giggles after Princess Bubblegum plays its circuits like a keyboard in "What Was Missing," when it reacts to being tickled by a feather in its sleep in "Guardians of Sunshine" and when it laughs and wriggles as its foot is being nibbled by a bear in "In Your Footsteps."

BMO's most prized possession is its controller, as it was stolen by the Door Lord in "What Was Missing."


One of the many abilities BMO has is a button (located under the D-pad) that sends the target into its main-brain-game-frame, where they are capable of playing video games as if they were really in them. BMO also possesses several attachments which can allow for other options aside from playing games, including a cord to allow for display of its screen to a wider audience. It possesses editing software for the making of films, but has personal choice regarding the footage that is used for the films it can create. BMO also contains keyboard-like tools, which are used by Princess Bubblegum in What was Missing." In "Conquest of Cuteness" BMO reveals a built-in camera with the flash emerging from the top left of its head while its screen becomes the lens. As seen in "The Creeps," BMO has a built in flash device that helps it take pictures, as well as a printer that prints out the rear. BMO also has a built-in alarm clock (set to Finn's bath time), as seen in "Holly Jolly Secrets Part I." It is also seen in this episode that BMO can insert VHS tapes into its back, and display the video on its screen. In "Incendium," BMO uses its BMO Cam, which is a live video feed. In "Daddy's Little Monster," it shows that BMO has the ability to charge electronic gadgets such as Jake's video phone. It appears to exhaust BMO, though. Perhaps because it most likely makes it release its own charge. 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. In "In Your Footsteps," it is revealed that BMO plays soccer, and it appears wears a red jersey, red cleats, and covered in dirt and mud. In "Card Wars," it is revealed BMO also skateboards as well is able to perform a sneak attack known as the BMO chop, after which BMO states "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.
