The Dragon/Music

In Rhapsody (of Fire)'s musically told-fantasy-epic, the Algalord Saga, Akron the Black King, prone to ravaging every proverbial puppy in the story is served loyally by The Dragon Dargor, a fearless and honourable half-demon warrior prince, who is apparently so awesome as to warrant an entire song of his own (with two variations!). All of this is a fairly transparent foreshadowing of Dargor's Heel Face Turn at the climax of the story. And HOW!
Cyborg Noodle acts as one to Murdoc in the Gorillaz canon.
Nikki acts as this for Doctor X in Queensrÿche's Operation:Mindcrime.
