Hair colour

Light brown flecked with grey[5][6]

"My kind don’t usually breed! It will be like me, I am convinced of it — how can I forgive myself, when I knowingly risked passing on my own condition to an innocent child? And if, by some miracle, it is not like me, then it will be better off, a hundred times so, without a father of whom it must always be ashamed!"
—Lupin's intense hatred of his condition as a Werewolf[src]

Professor Remus John[3]Lupin, O.M. (First Class), (10 March, 1960 – 2 May, 1998), also known as Moony, was a half-bloodwizard and the only son of Lyall and Hope Lupin(née Howell). He was afflicted with lycanthropy during his childhood, as a result of Fenrir Greyback's revenge against Lyall. He attended Hogwarts School of Witchcraft and Wizardry from 1971-1978 and was Sorted into Gryffindor House. During his school years he was one of the Marauders, best friends with Sirius Black, James Potter, and Peter Pettigrew. Together they created the Marauder's Map.

After Hogwarts, Remus and his friends joined the original Order of the Phoenix and fought in the First Wizarding War. However, Pettigrew betrayed James and Lily Potter to Lord Voldemort a week after he was made the couples' Secret Keeper. Thus Remus had lost all of his closest friends in various ways by the end of the First Wizarding War. The loss of his friends devastated him, though he and Sirius Black later rekindled their friendship.

Remus taught at Hogwarts School of Witchcraft and Wizardry as Professor of Defence Against the Dark Arts during the 1993-1994 school year. Remus was regarded by students to be the best Defence teacher they have had thus far. He was also a professor of Harry Potter (James' son) whom he taught how to conjure a corporeal Patronus, but resigned after Severus Snape revealed to the public that Remus was a werewolf.

He fought against Death Eaters once more in the Second Wizarding War, during which he lost his friend Sirius. In 1997, Remus married fellow Order member Nymphadora Tonks and had a son, Edward Remus Lupin, of whom he named Harry the godfather. Remus fought at the Battle of Hogwarts on 2 May, 1998, during which his wife was murdered by Bellatrix Lestrange. Remus was also murdered by Death Eater, Antonin Dolohov, during the first half of the same battle. His death was avenged by Filius Flitwick.

Remus briefly appeared again through the Resurrection Stone for Harry, along with James Potter, Lily Potter, and Sirius Black in 1998. After his death his son was raised by Andromeda Tonks and Harry Potter.

Biography

Early life (1960-1971)

Remus was born on 10 March, 1960 to Lyall and Hope Lupin. His father worked at the Ministry of Magic and encountered the werewolf Fenrir Greyback, who was on trial for killing two children. Lyall was the only one at court to realise that Greyback was a werewolf, as Greyback pretended to be a Muggle tramp. Outraged when Greyback was released, he voiced the opinion that Greyback deserved nothing but death. This opinion cost the Lupin family dearly, as Greyback decided to revenge himself upon Lyall by targeting his son. As the nearly five-year-old Remus slept peacefully in his bed, Greyback forced his way in through the window. Though Lyall was able to get there in time to drive Greyback off with powerful spells, he was unable to prevent him from completing his evil goal. Remus became infected with lycanthropy and he became a werewolf himself.

His parents took him to various healers and tried their best to make him a normal boy, but there was no cure for his condition. But Headmaster Albus Dumbledore made special accommodations allowing Remus to attend Hogwarts School of Witchcraft and Wizardry.

Hogwarts years (1971-1978)

"My transformations in those days were — were terrible. It is very painful to turn into a werewolf. I was separated from humans to bite, so I bit and scratched myself instead. The villagers heard the noise and the screaming and thought they were hearing particularly violent spirits."
—Description of Lupin's transformations[src]

Remus attended Hogwarts and was Sorted into Gryffindor House. To secure his safety, as well as that of his peers, Remus would be brought to the Shrieking Shack once a month for his transformations in order to prevent him from attacking other students. However, this isolation caused him to attack himself out of frustration. This, and the painful monthly transformations, made the villagers of Hogsmeade mistake his screams for that of violent ghosts. Dumbledore, wanting to keep the truth of these noises a secret, encouraged these rumours. Thus, the building was dubbed the Shrieking Shack, which held the reputation for being the most haunted building in Britain.
