Alastor 'Mad-Eye' Moody was a famed Auror, well respected for his impressive skills in his field. So nicknamed due to his detachable eye that gave him magical advantages, Moody often employed the uses of Dark Detectors such as Sneakoscopes or Foe Glasses to give himself the upper hand.
Following many years of tracking down the most dangerous wizards, he had become very careful about security, bordering on paranoid. His intense knowledge of the Dark Arts made him a perfect candidate for the Defence Against the Dark Arts post at Hogwarts… or so we thought.
In later books, Moody was an integral member of the Order of the Phoenix, where he helped lead the cause against Lord Voldemort alongside fellow Aurors, including his protégé, Nymphadora Tonks.
