Stereo Monovici is the crimson-red skinned alien plus the bookworm of the aliens. He was voiced by Jeff Bennett in Season 1 and Danny Mann in Season 2.


His personality is very smart, but intelligent according to the information, he was ultra-talkative and repetitive, plus he accumulates an encyclopedic glut of utterly worthless knowledge.

His exact personality is hard to determine. Mostly due to the fact that both heads act as two people. There are times that both will argue with each other. Plus, both will speak at the same time, finish each sentences, or take turns speaking. Stereo is quite superstitious at times.


Stereo is the tallest, slender red-skinned alien that has two heads. He is the overall bookworm of the house, always accumulating information no matter how important that is. Also, he is usually found reading or arguing with his other head. He is a very smart alien, but his intelligence is wasted on the most useless information often, for example, he has the ability to calculate any object or eveything else, including the exact length of a roll of toilet paper for a regiment of 500 parachutists or the number of sixteenth notes in a cantata by J.S. Bach. Plus, he lives in a closed world and ends up answering questions and some facts.
