Black Chest Demon

The four legendary heroes of Rogueport that were cursed by the Shadow Queen in Paper Mario: The Thousand-Year Door. The set 'curses' on those who open their Black Chests. Each curse will give Mario and his team new paper abilities.

Four Demons are locked in Black Chests, and beg for you to free them, saying you will help them. But when they come out, the Black Chest Demons place a curse on you. Fortunately for you, their curse is in your favor (a concept reused from several Legend of Zelda games) - they are how you obtain your four special Paper abilities. It is later implied they are actually the four heroes of legend that were cursed by the Shadow Queen after sealing her away.

Grifty tells the story of their adventure and how they came to be trapped in chests.
