Gargoyle's Quest: Ghosts 'n Goblins is an action-adventure/ platformer game for the original Game Boy. Developed by Capcom, it was released in July, 1990 in North America. The playable character Firebrand made his debut in the video game series Ghosts 'n Goblins as an antagonist character, of which this is a spin-off.

The game consists of two gameplay styles. One half has the player traverse an overhead view, either on the world map or in towns. This is broken up by the other type of content: individual, action-platforming levels that sometimes feature a boss at the end. While traversing in the sections with an overhead view, the player is able to talk with residential ghouls and, if outside a town, is susceptible to random battle encounters. The player then must defeat the enemies in order to return to the overhead-view map. While on the overhead map, the player occasionally comes across ghouls who want to fight Firebrand for various reasons.
