Harry Potter, boy wizardJ.K. Rowling: “(1980 – ) The Boy Who Lived, only known survivor of the Avada Kedavra curse and conqueror of Lord Voldemort, also known as Tom Riddle. Harry Potter joined the reshuffled Auror Department under Kingsley Shacklebolt at age 17, rising to become Head of said department in 2007.”

I’ve really fallen behind, Harry’s been Head of the Auror Department for three years.
