~ Earl (aka EP-327), before fighting Rusty.)

EP-327 is the powerful, yet aggressive early prototype of Rusty. He is the of the animated series Big Guy and Rusty the Boy Robot based on the 1995 comic book The Big Guy and Rusty the Boy Robot by Dark Horse Comics. He first appeared as the main antagonist of the episode "Sibling Mine" and made another appearance in another episode "Sickout". He has an underdeveloped emotion grid and follows orders literally.



  • He was voiced by Pamela Adlon (also credited as Pamela Segall Adlon) who also voiced Rust the Boy Robot throughout the entire show.
