The Grim Reaper (simply known as Grim) is one of the Cartoon Network heroes that were summoned & defeated by Strike, he is also the main protagonist The Grim Adventures of Billy and Mandy.

In his series Edit

The Grim Reaper (simply known as Grim) is a walking skeleton who became Billy and Mandy's best friend after losing a limbo game, but what's even worse is that Grim himself accidentally lets Billy use his supernatural powers like using a magic zipper for fun, using his own magic to change Billy's grade, among others. Billy treats Grim like a very unique person, while Mandy, on the other side, treats Grim like a mediocre creature by abusing him (since she is the most grumpiest character in the entire series). Everything went to far for Grim's relationship with Billy and Mandy when he was arrested by the Underworld military for misusing his powers, especially when he lost them to Numbuh Three from Codename: Kids Next Door. Grim got his powers back when he saved them from a future ruled by old rival, the Boogey Man (simply known as Boogey).
