Professor Remus John Lupin (10 March 1960 – 2 May 1998), also known as Moony in the Marauders group, is a major character in the Harry Potter franchise, debuting as the deuteragonist of Harry Potter & The Prisoner of Azkaban and acting as a major protagonist in each of his subsequent appearances.
He was a half-blood wizard (son of Mr. and Ms. Lupin), affected with lycanthropy after a bite from Fenrir Greyback.
In the films, he was portrayed by David Thewlis, who also voiced Earthworm from James and the Giant Peach.
He was born as Remus John Lupin in March 10, 1960.
He attended Hogwarts School of Witchcraft and Wizardry from 1971 to 1978 and was sorted into Gryffindor house. During his school years, he was one of the Marauders; he was best friends with James Potter, Sirius Black, and Peter Pettigrew. Together they created the Marauder's Map. After Hogwarts, Remus and his friends joined the Order of the Phoenix and fought in the First Wizarding War. However, Pettigrew betrayed James and his wife Lily to Lord Voldemort, out of fear. Remus lost all of his closest friends in various ways by the end of the First Wizarding War, though he and Sirius Black later reclaimed their friendship.
Remus taught at Hogwarts School of Witchcraft and Wizardry as Professor of Defense Against the Dark Arts during the 1993–1994 school year. He was also a teacher of Harry Potter, James's son, whom he taught how to conjure a Patronus, but resigned after Severus Snape (who was bullied by Remus, James, Sirius and Peter in their school years) revealed to the public that Remus was a werewolf. He fought against the 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 (who was 13 years his junior) and had a son, Teddy Lupin. Remus fought at the Battle of Hogwarts, during which his wife was killed by Bellatrix Lestrange. Remus was also killed by the Death Eater, Antonin Dolohov, during the same battle in 1998. However, he briefly appeared again through the Resurrection Stone for Harry, along with James, Lily, and Sirius in 1998.
