Prismo

Prismo is a being who was first mentioned in "The Lich", and a main character in the episodes "Finn the Human " and "Jake the Dog " He dwells in the Time Room which is found in the center of the multiverse (He calls it his time room). Booko describes him as "almighty." This is proven true, as Prismo can grant every being in the multiverse one wish. Once the wish is granted, the wisher is transported into his/her wish-altered reality.

Prismo's wishes are powerful enough to change timelines, and create or destroy worlds. However, unless worded very specifically, his wishes usually have an ironic twist.

Prismo also has a "TV wall" which he can use to watch people's wish altered realities, though it is unknown wether or not he uses it frequently. Prismo also owns a hot tub, as seen in "Jake the Dog".

Relationships
Prismo is seen with the Cosmic Owl, and the two appear to be close friends. Prismo does not appear to be interested in having a girlfriend, his primary reason being that he doesn't want to spend time discussing what to eat, and that he can eat whatever he wants when he is alone. He also develops a friendly relationship with Jake the Dog, and sends him a note saying that if he wanted to come back and hang out sometime, to "call" him. He signed "P", short for "Prismo" on the note.
