Ancient Sleeping Magi of Life Giving

The Ancient Sleeping Magi of Life Giving is a wizard who has the ability to give life to inanimate objects, fly, and phase through objects. He is seen sleeping at the center of the dungeon in "Mystery Dungeon" engulfed in blue flames. The alignment of the newly animated creature is affected by his mood when he touched it.

He wears oven mitts on his hands to prevent accidentally using his powers, and went so far as to bury himself underground to avoid using his power. When he breaks into Finn and Jake's home, we see that he can both animate and deanimate the objects he brings to life. It seems that when he thinks of his father, the creatures he brings to life are bent on causing chaos and destruction, and when he thinks of his mother, the creatures seem much more intelligent and generally want to just hug everybody.

In "Mystery Dungeon," Ice King kidnaps Tree Trunks, Neptr (whom he confuses with BMO), Lemongrab and Shelby to help him pass the labyrinth which leads to the Magi. Once they make it there, Ice King throws his Fionna and Cake fanfiction into the Magi's flames, in hope all of his imaginary characters will come true. Instead, the book itself is brought to life by the Magi. After being offended by Ice King, the Magi leaves the labyrinth.

To protect everyone from a disaster, the Magi buries himself underground so that he wouldn't bring something to life in "Little Dude." However, Finn's hat touches the flower that grew on top of his head and is brought to life. That night, he sneaks into Finn and Jake's house. They ambush him, and he reveals everything that he brings to life becomes evil due to the bad relationship he has with his father.

However, he's late and Finn's hat travels to the Candy Kingdom. It takes control of a citizen and starts wreaking havoc and manages to take control of a Gumball Guardian. The Magi learns things he bring to life become good if he thinks about his mother. The formerly inanimate objects he creates defeat their brother. At the end of the episode, Finn gives his living hat (now turned good) to the Magi so that he could raise it as his child.
