The Martian King is a minor character in Dexter's Laboratory. He only appeared in the episode "The Mock Side of the Moon".


The Mock Side of the Moon[]

In his only appearance, the Martian King and his aliens were in an arena having a discussion about it being cold on the moon and they need sweaters. Dexter misheard the leader using a translation device and comes under the assumption that the aliens were going to attack the Earth. With this, he then uses the Robo-Dexo 2000 to destroy all alien spaceships and homes, prompting the Martian King to ask Dexter why he attacked them when all they needed was sweaters because it was cold on the moon. Realizing his mistake, Dexter makes amends with the Martian King and works with him to make sure that all the aliens have sweaters to keep them warm.
