Peppermint Butler is Princess Bubblegum's butler. He first appeared in the animated series Adventure Time.
Peppermint Butler was created by Pendleton Ward.
While he appears at first to be an ordinary butler, Peppermint Butler has connections to the realm of the dead, and is a master of dark magic. He is a personal friend of Death.
Peppermint Butler stars alongside Cinnamon Bun in a spin off comic named Adventure Time: Candy Capers. In the series, the pair try to solve mysteries on the Land of Ooo, in a homage to the crime noir genre.
