Grim & Evil was the "precursor" to The Grim Adventures of Billy & Mandy. Each show featured either two segments of Grim and one with Evil (meaning episodes of The Grim Adventures of Billy & Mandy and Evil Con Carne), or two of Evil and one with Grim. Both were created by Maxwell Atoms. The pilot was made in 1999 and aired in 2000 on Cartoon Network's Big Pick, and the show itself premiered on August 24, 2001. All of the characters in Grim made it into Grim Adventures when the two stories spun off into their own shows in 2003. Although Evil Con Carne only lasted two seasons, the characters have appeared in Grim Adventures from time to time.
