Remus Lupin

Remus Lupin is a canon character in the Harry Potter books. He is a half-blood wizard and the only son of Lyall and Hope Lupin. When he was a child, Remus was bitten by Fenrir Greyback and became a werewolf. He attended Hogwarts School of Witchcraft and Wizardry from 1971-1978 and was sorted into the Gryffindor house along with his best friends James Potter, Sirius Black, and Peter Pettigrew.

Because of Remus, his best friends managed to transform into Animagi to help him every month during the full moon.
