BMO has a pivotal part in " Come Along With Me," the series finale. He spends the majority of the episode in the Tree Fort, thus sitting out of the whole battle between Gumbald and Princess Bubblegum. When GOLB appears on the battlefield and seemingly swallows Finn, Betty Grof and Ice King, Jake rushes to try stopping one of GOLB's monsters and save at least BMO and the Fort. BMO's behavior when he is alone could be a reference to Isaac Asimov's " Catch That Rabbit," in which a robot acts strangely when it thinks it is not being watched. In the episode " What Was Missing," BMO has his 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 " Be More," BMO's purpose as "being more" is revealed, and he reunites with their father, Moe. BMO deletes some of his files for fun, but accidentally deletes his 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. 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 special features section of the It Came from the Nightosphere DVD, BMO's age is shown as "VER. 2600" and his species kind is revealed to be "110 VOLT-60 HERTZ SYSTEM." In the episode " The Creeps," he was 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, he is discovered by Finn in Lady Rainicorn's body, being in the prank with Jake and the others. In the same short, 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 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.

BMO looks like a Macintosh computer with Game Boy Color buttons and Atari 2600 controllers. He also shares some traits with a Vectrex. BMO, Finn and Jake’s computer/robot, is comic relief for the series. He lives with the boys and acts as their video game, television, and many other things. He has a childlike personality – and deserves a series all of his own. In the Macy's Thanksgiving Day Parade for 2013, a group of people each dressed as BMO helped parade the Finn and Jake balloon.

It seems that Marceline and BMO have a fairly friendly relationship, as she is seen playing them 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 " Ketchup," Marceline and BMO hang out and tell each other stories. As seen in " James Baxter the Horse," " Davey" and " Imaginary Resources," BMO can cry, and his tears are apparently triangles. 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 they could "Be 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 their creator. The two embraced shortly after Moe fixed BMO's operating system informedly than revealing his creation's family in an underground civilization of happy MOs. The adventure is about to begin! The new Funko Pop! Animation: Adventure Time – BMO Robin Hood Funko Pop! Vinyl Figure – Hot Topic Exclusive inspired buy the “Furniture and Meat” episode, whereBMO and Neptr are seen playing “Robin Hood” together, with BMO as Robin Hood and Neptr as the Sheriff of Nottingham. BMO is a medium-sized teal/blue-green gaming device, sometimes appearing with one or two controllers attached to them. When not being played, they have an 8-bit face.

BMO often acts to maintain the harmony of friendship between Finn and Jake. In " Video Makers," BMO edits 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," BMO refuses to play such games with Jake because Jake cannot deal with losing. When Finn asks for advice on Jake's attitude, BMO recommends that Finn play to lose. Once the exclusive collectibles are announced, we post shared retailer guides on the associated announcement blog. Those who cannot attend the event in-person can look to the shared retailer guides to know where they can go to try and collect the items they're on the hunt for. When applicable, we'll also post guides for items available through international partners.

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 their d-pad. By doing this, users are able to play the game in a virtual reality where they can physically complete objectives, with the possible risk 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 a personal choice regarding the footage that is actually used to make up their films. Other safe places to buy from are many Funko Pop Facebook groups – the community on these group chats are wonderful and people are keen to offer advice and help out on all Pop matters. 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 to drink the tea with their pinkie finger up, but Football does not. BMO drinks, again and again, resulting in self-electrocution. BMO has never been seen actually consuming food. Despite this, BMO can cook, and makes dinner for Finn and Jake in " Little Dude (episode)." In " The Creeps" BMO reveals enjoyment in taking nice pictures. BMO also likes to dance. For those looking to simply collect the bobbleheads for their own personal collection, there is personal value in purchasing a Funko Pop! that brings a sense of joy, nostalgia, or an amalgamation of the two.

BMO's BMO Chop memory (which originated from " Card Wars") was deleted in "Be More" as it implies that, unless it gets re-uploaded, we will never see it again. While our Funko Pop price guide indicates that some Funko Pop! categories are generally more valuable than others, there are still collectibles within those categories that offer even beginners an opportunity to collect. 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 & Meat," BMO is shown to like pretend-sword fighting with Neptr at the start of the episode.
