Pacman (also known as "Paccy" or "Pac") is a fictional copyrighted video game character from the Pacman series and he appeared in the show, Greeny Michael. He is best friends with Luxo Jr.
How Pacman was formatted (according to the Greeny Michael wiki)Edit
On Greeny Phatom, Gangster Sailor was fighting Little Guy at the arcade. He knocked over the Pacman game and Pacman popped out of the game and beats up Gangster Sailor. Then, he saw Pixar playing Fix It Felix Jr. And that's how they became friends.
