According to Finn, "BMO does weird junk when no one is around." BMO once acted out a film noir fantasy complete with giving names, voices, and dialogue to a number of animals and an inanimate object in the house. Most believe this is BMO's hyperactive imagination, though; ALLMO says positively of BMO, "…Your imagination lets you see the world how it could be."
BMO is very protective of Finn and Jake. BMO once said, "If anyone tries to hurt Finn, I will kill them." He once 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!"
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.
