The Grim Reaper came for Wakko when he ate the last Swedish meatball at the Swedish Meatball Convention before he was dying. He engages in a chess match with the Warners, but they prefer checkers. He says that if he wins, the Warners have to say with him forever. If the Warners win, they get to stay together. However, the Warners cheat and win, but Grim says that it was a loophole, making the condition null and void. The Warners torment him until he eventually let's them back into the real world? He is voiced by Jess Harnell.
