Remus- Do you think your animingus says something about you James- definitely! Sirius is energetic and loyal, but will bite back if he feels threatened. That's why he's a dog Sirius- and James your a stag because your like the king of the forest, wanting to look out for your friends and family.
Photo: By their fifth year, Sirius was able to become a dog, and James was able to become a stag, animals large enough to keep the wolfish Remus in check. Peter, meanwhile, was able to become a rat. Under their influence, Lupin became tame; his body was still a wolf's, but his mind became less so when he was among them.
