BMO

Beemo (or BMO) is Finn and Jake's video game system and roommate. He makes his appearance in the title scene of the Theme Song of every episode of Adventure Time, just before Finn and Jake pound their fists together.

Episode appearances
He made a cameo appearance in the episode "Evicted!", being played by Marceline while Finn and Jake are going house-hunting. He is also seen in "Business Time" when Finn and Jake are playing Adventure Masters on him. Also, in "Business Time", Finn and Jake are seen playing an Abraham Lincoln game (a reference to the Animated Short). He is later seen in the episode "My Two Favorite People". In "The Witches Garden", Finn was playing a game while discussing with Jake about how he got his magical powers. Beemo also is seen in "What is Life?" when Jake throws a garbage bag of butter on Finn, and in the episode "Donny" where one of the controls is smashed in half. Beemo claims to not have emotions, but Donny angers him by breaking a controller and throwing it at him.

In "Rainy Day Daydream", he shows a bored Finn and Jake a new game, "Conversation Parade". Beemo appears again in "Slow Love" where he acts like a rebellious kid, refusing to turn down his music when Jake tells him. He is then pummeled and battered when Snorlock starts dancing with lady snails while the tree house is on his back, but is apparently unharmed and returns to play music at the end of the episode. In "Power Animal", Beemo distracted Jake with songs.

They were later eating lunch together and Jake told him to hold his sandwich. He was later seen fixing the well overhang that lead to the gnome's underground hideout that Jake had destroyed while entering. In "Guardians of Sunshine", it is revealed he has a button hidden under his control pad that allows people to be transported in games. However, he does not allow Finn and Jake inside him, claiming it's too dangerous of an adventure. Despite his warning, Finn and Jake trick Beemo by tickling him with a feather until he presses his button while he is sleeping. He 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 him. He is then attacked by Sleepy Sam, Hunny Bunny, and Bouncy Bee for imprisoning them in the game. After Finn performs a combo move, he scolds them for going in the game and starts doing the combo move on them.

In the episode "Conquest of Cuteness" Finn and Jake call Beemo over to get a camera to take pictures of the Cuties but it turns out Beemo is a camera even though in the episode "Video Makers" Beemo has a video camera strapped to his head.

Appearance
He is a medium-size green handheld gaming device, sometimes appearing with one or two controllers attached to it. When he's not being played he has a pixelly face. The letters "BMO" are printed on his sides, indicating his name. Also, he has a button that sends the target into his main-brain-game-frame.

Beemo possesses several attachments which can allow for other options aside from playing games, including a video camera that allows for the making of movies and a cord to allow for display of its screen to a wider audience. He also possesses editing software for the making of films, but has personal choice regarding the footage that is used for the films it can create. In "Conquest of Cuteness" Beemo reveals a built-in camera with the flash emerging from the top left of his head while his screen becomes the lens.

Gender
Despite usually being referred to as a "he," Beemo has been confirmed to be genderless. Beemo is referred to as "M'lady" by Finn in "Conquest of Cuteness", but Adam Muto has stated this doesn't mean anything via his Formspring.

Trivia
