Prince Charming

Origin
Prince Charming is a stock character who appears in a number of fairy tales. He is the prince who comes to the rescue of the damsel in distress, and stereotypically, must engage in a quest to liberate her from an evil spell. This classification suits most heroes of a number of traditional folk tales, including Snow White, Sleeping Beauty and Cinderella (among others), even if in the original story they were given another name, or no name at all.

These characters are often handsome and romantic, a foil to the heroine, and are seldom deeply characterized, or even distinguishable from other such men who marry the heroine.
