Kee-Oth

Kee-Oth is the demon who created the Demon Sword with his own blood, which was taken by Jake's father, Joshua. He appears in the first message left by Joshua for Finn and Jake, where he was defeated with the spell "Kee Oth Rama Pancake." He appears at the end of "Dad's Dungeon," yet again demanding his blood back, but was repelled by Jake with the same spell.

He returned in "Play Date" where Ice King and Abracadaniel brought him back by reading an inscription on the Blood Sword. He grabbed them both and threatened to kill them if Finn didn't return his blood. Finn broke the Blood Sword in half and released Kee-Oth's blood back to him, causing him to grow greatly in size and power. He then grabbed Jake, thinking he was Joshua (and unaware that Joshua is dead), and teleported away.

​Appearance
Kee-Oth's initial appearance was that of a large, black-skinned demon with large, bright green eyes. He has thin legs, and torn up black wings. He also possesses a long, slightly curved tail and two horns, one of which has had the tip broken off. His large, gaping mouth is filled with sharp teeth and his ears are long and pointed. His muscular arms are long and gangling, and end in flat hands with long, pointy fingers.

When his blood is returned to him via Finn breaking the sword, he becomes almost four times larger and his skin becomes a bright red. Whenever he is summoned, banished, or teleporting he is engulfed in flames and before disappearing when the flames die down.
