Alastor "Mad-Eye" Moody (d. 27 July, 1997) was a pure-blood Scottish wizard, considered to be the most famous Auror of all times. He was also 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. He was also responsible for many of the inhabited cells in Azkaban, having caught innumerable Dark Wizards. As a result, 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 kidnapped by Barty Crouch Jr, who disguised himself as Moody.
Later, the real Moody was rescued and 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 of the Seven Potters in 1997, where he was murdered by Lord Voldemort.
His magical eye was later used by Dolores Umbridge to spy on her subordinates in the Muggle-Born Registration Commission, but was later retrieved by Harry Potter during the Infiltration of the Ministry of Magic in 1997, and was given a proper burial by Harry in the forest near where the 422nd Quidditch World Cup had been held three years earlier.
