Prof. Lupin

Prof. Lupin is the Defence Against the Dark Arts teacher at Hogwarts.  He is young, but has lines on his face and is getting gray hair. When Prof. Lupin was younger he was bitten by a werewolf and hence, now turns into a werewolf when there is a full moon. To make himself a "harmless wolf" he drinks a special potion that Prof. Snape makes him, on the DAY of the full moon.  Then he will curl up in his room and sleep, completely safe.
