"You could do with taking a leaf out of Percy's book!"
     -- Molly Weasley to Fred, George, and Ron

Grown son of Arthur and Molly who recently left Hogwarts (June 1994) and is now employed by the Ministry of Magic in the Department for International Cooperation. Percy is devoted to rules and procedures, and Ron isn't entirely sure he wouldn't "pull a Crouch" and turn his own brothers in if they broke Wizard law. At Hogwarts, he was a Prefect and Head Boy. His girlfriend at Hogwarts was Penelope Clearwater. Percy has red hair. He is tall and thin and wears glasses.
