Gnome Ruler

Gnome Ruler appears in "Power Animal." He is the Grand Master of the Gnomes and leader of The Beneathaverse. He first appeared at Finn and Jake's party on the top of their tree house in disguise as a "spy." Standing on the shoulders of his Gnome Minions, he disguises himself as a tall, plump man wearing a large blue coat. He learns that Finn's powers are "endless" and later kidnaps Finn when he was sleeping. He ties up Finn and chains his feet to a pole. He brings Finn to an underground lair filled with giant machines and his gnome minions. He reveals to Finn that he is actually the Grand Master of the Gnomes and the ruler of The Beneathaverse, the underground world that the gnomes live in, and that he had been looking for someone with endless power for his machine, the upturnoverdrive, which will turn the world upside down so that gnomes would rule the world. The gnomes use Finn to power tons of different machines and shock him whenever he becomes tired. They are powering their last machine when suddenly Jake jumps down and begins smashing all the machines and freeing Finn. The gnome leader attempts to blast Jake while he had the power of ultimate partyanimalness bestowed upon him by the Party God, with a laser, but Jake punches and destroys it, defeating the gnome ruler.
