Alastor Moody, more commonly known as 'Mad-Eye' Moody, is a renowned Auror working for the Ministry of Magic and member of the original Order of the Phoenix. He retired before 1994, but for Albus Dumbledore agreed to become Defence Against the Dark Arts Professor at Hogwarts, a post he never reached as he was attacked by a Death Eater who impersonated him. He also joined the recalled Order of the Phoenix after Voldemort's return. Moody was allegedly paranoid of Death Eater attacks, though quite often his caution was proved justifiable. He was killed by Voldemort in 1997 whilst playing a part in an operation organised by the Order to move Harry Potter to safety.
 Character development
During the first Wizarding War, Moody was one of The Ministry of Magic's most renowned and powerful Aurors. He successfully fought many of Lord Voldemort's death eaters and was thought that half the cells in Azkaban were filled by death eaters Moody had captured. They Ministry also late granted Aurors to use the unforgivable curses in which Moody killed Evan Rosier. Sometime before the start of the 1994 school year. Albus Dumbledore hired Moody to be the new Defence Against the Dark Arts Professor at Hogwarts.
 Fourth book
We first hear about Mad-Eye Moody on the first of September 1994 when Ministry worker Amos Diggory warns Arthur Weasley, a friend of Moody, that members of the Improper Use of Magic department are on their way to punish Moody. This was after Moody's Muggle neighbours heard bangs and shouting and called the police to investigate, where they saw his spelled dustbins rocketing around. This was a potentially dangerous situation for Moody as he was risking exposing the magical world to Muggles, but he was claiming that he had heard an intruder who was the one to set off the dustbins.
This later was proved to be false. The Muggles had really heard Alastor Moody engaging in a duel with Death Eaters Peter Pettigrew and Barty Crouch. By the time the Ministry officials arrived, Crouch had impersonated the defeated Moody by using Polyjuice Potion. He also took the real Moody's eye and false leg. Arthur Weasley was able to save 'Moody' from the Improper Use of Magic group. Crouch was then free to go to Moody's new job, as Defence Against the Dark Arts teacher at Hogwarts.
As a result of this Harry and his fellow students did not meet the real Moody. He was locked up in his own trunk, kept alive and near at hand by Crouch who needed his hairs to continue making Polyjuice Potion, which he needed to drink hourly. Harry first saw the genuine Moody in one of Albus Dumbledore's memories, when he looked into his Pensieve. There he found memories of various trials which Dumbledore had been present at as a member of the Wizengamot. In that time Moody had both of his eyes. He also addressed Dumbledore as 'Albus', something his imposter neglected to do.
Alastor Moody was not freed until the 24th of June 1995, when Crouch gave himself away by removing Harry from Dumbledore's sights after Voldemort's return. Dumbledore then realising that he must be an impostor, Stunned Crouch and emptied out his hip-flask revealing it to contain Polyjuice Potion. He then opened Moody's trunk, which has seven keys that each unlock the trunk to reveal different contents. The seventh key turned the trunk into a pit, with the real Alastor Moody unconscious inside it. Crouch was then questioned under the influence of Veritaserum, revealing what had happened to Moody.
Moody was then taken to the hospital wing and put under Madam Pomfrey's care. Mad-Eye Moody was present at the Leaving Feast and sat on the teachers' table. He appeared extremely nervous and jumped every time everyone spoke to him. His imprisonment had apparently increased his fear of being attacked.
 Fifth book
Moody makes an unexpected appearance at Number 4, Privet Drive as part of a group of volunteers from the newly recalled Order of the Phoenix. It is a particularly strange experience for Harry, who was technically meeting and speaking with him for the first time, despite having thought that he had known him for a year. Also present was Mad-Eye's protégée, Nymphadora Tonks. He later came to the aid of several members from Dumbledore's Army during the Battle of the Department of Mysteries. He was injured by Antonin Dolohov though ultimately survived the battle.

 Outward appearance
[His face] looked as though it had been carved out of weathered wood by someone who had only the vaguest idea of what human faces were supposed to look like, and was none too skilled with a chisel. Every inch of skin seemed to be scarred... [one eye] was small, dark and beady. The other was large, round as a coin, and a vivid, electric blue.
Mad-Eye Moody certainly cut an impressive figure. His many duels with Death Eaters over the years had left him scarred and one limb short. A Death Eater called Evan Rosier had taken out a chunk of his nose and he presumably lost his eye and leg in duels as well.

 Magical accomplishments and skills
Alastor Moody was a highly skilled Auror. He was a good dueller as well as being able to plan difficult and dangerous operations, often taking the lead.
- A magical eye to replace one he lost. This eye could swivel around in its socket 360º and see through solid objects, including the back of his own head. It could also see through Invisibility Cloaks, including Harry's one, despite its being one of the Deathly Hallows. Since it was worn by Crouch who impersonated him for a year, it often got stuck.
- A carved wooden leg to replace one he lost, complete with clawed foot.
- A trunk with seven locks and seven keys. When each key opens its lock, the trunk opens revealing a different set of contents occupying what is apparently the same space in the trunk. The seventh key turns the trunk into a pit.
- A hip-flask, which was the only thing he would drink from in order to prevent his drink from being spiked with poison.
- Two Invisibilty Cloaks, one better than the other.
- Dark Detectors
- Foe Glass
- Secrecy Sensor
- A photograph of the original Order of the Phoenix.
