Demon's Crest, known in Japan as Demon's Blazon, is a side-scrolling platform video game developed and published by Capcom for the Super Nintendo Entertainment System. It is the third video game starring Firebrand, following Gargoyle's Quest and Gargoyle's Quest II.

The game's story revolves around the Crests, six magical stones which preside over their respective elements (Fire, Earth, Water, Air, Time and Heaven). When all crests are combined, the Crest of Infinity will appear, allowing its holder infinite power and the ability to conquer all realms with it. The demons of the Demon Realm have long fought each other for possession of the Crests, five of which have since fallen into the hands of a red demon named Firebrand. Seeking infinite power, Firebrand challenges a Demon Dragon for the Crest of Heaven and is victorious, though badly wounded. In his weakness, a rival demon named Phalanx ambushes Firebrand and takes all the Crests except the Fire Crest which shattered into five shards.
