Singe is a dragon and the main antagonist from the Don Bluth 1983 video game Dragon's Lair and the secondary antagonist of the series. He has kidnapped Princess Daphne and it's up to Dirk the Daring to save her.
Singe is found deep in the treasure room of his castle. Once Dirk encounters him, he runs to retrieve the Magic Sword in the middle of the treasure room. Once he has the Magic Sword, he throws it to Singe's chest, killing him, then takes the key from around his neck to free Princess Daphne from the orb Singe imprisoned her in.
In the 1991 sequel, Dragon's Lair 2: Time Warp, Singe's skeletal remains are found in the same treasure room in the beginning of the game.
