Remus Lupin was one of the four Marauders, Moony, and co-creator of the Marauder's Map. His three best friends were James Potter, Sirius Black and Peter Pettigrew. When Remus was a young boy he was bitten by a werewolf, Fenrir Greyback (rumor) , and thus become one himself. Albus Dumbledore let him come to Hogwarts, planting the Whomping Willow at the entrance of the Shrieking Shack, so that he could go there each month to transform. At Hogwarts he met his three friends and they all became Animagi to make his transformation more enjoyable, and meant more sanity.
Teaching at HogwartsEdit
In Harry's third year, Lupin became the Defence Against the Dark Arts teacher. He wore shabby clothes because as a werewolf it was hard for him to find a job. He also helped to fight off Dementors on the Hogwarts Express and became a close friend of Harry, also letting him talk to a friend of his parents. He also became the favourite teacher of many students, teaching them how to fight many magical creatures such as boggarts, grindylows, and kappas. Sadly, once his everyone knew he was a werewolf , had the urge to resign.
Marriage and deathEdit
Around summer of 1997 Lupin married Tonks and in the spring of that year they had a son named Teddy Remus Lupin. Harry Potter was the godfather. Unfortunately during the battle of Hogwarts in '97 both Lupin and Tonks were killed, making Teddy much like Harry. Lupin was the last of his three friends to die, he was only around 38 years old.
