What is my problem with man, you ask? No. I ask you, what was man's problem with me?
~ Simion

Simion is the titular antagonist in one of the episodes of the Dexter's Laboratory spin-off Dial M for Monkey.

He was voiced by Maurice LaMarche.


When he was a common primate, Simion was set to be the first monkey in space. However, his mission failed. A crack in the space capsule's hull created an explosion that hurled him toward a radioactive energy imbalance, the radiation altered his appearance and mind giving him enhanced strength and intelligence, turn so a mutated anthropomorphic primate. He began to build a new world, training his new body and expanding his knowledge and skill through meditation, soon being able to create matter merely by thought, becoming so a powerful galactic warlord.

With his new abilities he created a whole new world from his thoughts and once he established his empire he created an immense warship from scrap over half a century, and assembled an army to help him destroy the Earth and the humans that ruined his life. Then, he says Monkey that he is also a strong and intelligent ape and that combining their forces they could bring a new galactic order.

He gives reasons for this telling him that no human has shown him true love and affection. But Monkey, after a series of flashbacks spending quality time with Agent Honeydew, showed Simion a true simple act of kindness with the gift of a banana given to him by her. Simion realized the error of his ways and destroyed his army and went to live a happy care free life in the wilds of South America.


  • His name is a pun of the word "Simian".
  • His biography could be a parody of the primates in Planet of the Apes. Another thing to consider about is that his voice (played by Maurice LaMarche) is meant to be an impression of the late Charlton Heston as a reference to his starring role in the 1968 film.
  • He is a reference to the DC Comics villain Vandal Savage.
