The Sun is an ancient star that appears in most episodes of Adventure Time. The Fire Elemental asks for directions to it in the animated short. In "Guardians of Sunshine," Finn and Jake find out that the titular Guardians from BMO's game just wanted to feel its rays. In the episode "Something Big," it is revealed to be sentient and gives an inspirational speech to the Ancient Psychic Tandem War Elephant.
Hey! Elephant. I'm more ancient than you. Someday, I will engulf the solar system. What was and what will be are meaningless. Meanwhile, you should wonder: are you just a two-headed pile of meat on a crash course with the cosmic dump? Or do you contain the soul memory of a million dead stars? How do you light a candle without a match?
- King of Ooo is the self-proclaimed owner of the Sun.
- In "Water Park Prank," he is referred to as "Mr. Sun."
