Earthworm Jim is the protagonist of the video game franchise of the same name. He was once an ordinary earthworm that lives in Earth (mostly in New Junk City) until a space suit from outer space fell into the sky and caused him to become the hero he is today.
In the first and second games, he was voiced by Doug Tenapel (the creator of the franchise) while in the cartoon series, and Earthworm 3D, he is voiced by Dan Castellaneta who also voiced Homer Simpson from The Simpsons.
