Percy Ignatius Weasley is a fictional character in the Harry Potter series. He is a son of Arthur Weasley and Molly Weasley, a younger brother of Bill Weasley and Charlie Weasley and an older brother of Fred Weasley, George Weasley, Ron Weasley and Ginny Weasley. His younger brother Ron is a close friend of Harry Potter and Hermione Granger. Percy's birth is estimated c. 1977. He entered Hogwarts School of Witchcraft and Wizardry in 1987.
When the readers first meet Percy, in Harry Potter and the Philosopher's Stone, he is a prefect, and in Harry Potter and the Prisoner of Azkaban he becomes Head Boy. He is relatively humourless, and thus the butt of many of Fred and George's jokes and pranks.
Warning: Wikipedia contains spoilers.
In Harry Potter and the Chamber of Secrets, he is shown to be behaving in a secretive manner, perhaps as a red herring to lead the reader to believe he is responsible for the opening of the Chamber of Secrets. It is later revealed that he secretly has a girlfriend, Penelope Clearwater, a Ravenclaw.
In Harry Potter and the Prisoner of Azkaban he reached his final year at Hogwarts. He graduated in June, 1994 at the age of seventeen and he soon started working for the Ministry of Magic under Mr. Crouch whom he looked at like something of an idol in Harry Potter and the Goblet of Fire. In Harry Potter and the Order of the Phoenix. he began working with Cornelius Fudge, himself, and practicaly abandoned his family.
In the films, he is played by Chris Rankin.
