Remus John Lupin is a canon character in the Harry Potter books. He is a Gryffindor at Hogwarts school, a werewolf, and best friend to James Potter , Sirius Black and Peter Pettigrew, who gave him the nickname "Moony".
He became friends with these three in second year, when they discovered he was a werewolf because he always missed Astronomy on the full moon. Pettigrew left a note on his bed telling him to come to an abandoned classroom. He did so, and there they revealed they knew his secret, but were not afraid of him, and pledged to do whatever they could to help him through his transformations. It is for this reason that the three other boys became animagi: James a stag, Peter a rat, and Sirius a dog.
Physical Description Edit

He was in love with Nymphadora Tonks, but refused to act on his instincts because he thought she would reject him when she found out what he was. Also in love with Sirius Black.
