"You-Know-Who acted exactly as Mad-Eye expected him to, Mad-Eye said he'd expect the real Harry to be with the toughest, most skilled Auror. He chased Mad-Eye first."

—Nymphadora Tonks on Moody.

Alastor "Mad-Eye" Moody (d. 27 July, 1997) was a wizard, arguably the most renowned Auror of all time, and a pivotal member of the Order of the Phoenix during the First and Second Wizarding Wars. Moody served with distinction during the first conflict, gaining a considerable reputation, as well as losing an eye, leg, and part of his nose while fighting the Dark Arts. To this end, Moody became overly-cautious and paranoid about his security. In 1994, he accepted Albus Dumbledore's offer to teach Defence Against the Dark Arts at Hogwarts, but was temporarily kidnapped by Barty Crouch Jr., who disguised himself as Moody. After he was rescued, the real Moody became a member of the second Order of the Phoenix. He fought in several battles of the war, including the Battle of the Department of Mysteries in 1996 and the Battle over Little Whinging in 1997, where he was killed by Lord Voldemort. His eye (the only part of Moody that was found) was buried by Harry Potter in the Forest near where the 422nd Quidditch World Cup had been held three years.
