Animagus

An Animagus (pl. Animagi) is a witch or wizard who can turn into an animal at will. Learning how to become an Animagus is difficult; it took James Potter, Sirius Black, and Peter Pettigrew the better part of two years to figure out how to do it. The form one takes on as an Animagus reflects their personality. Animagi are required to register with the Ministry of Magic, to ensure they do not cause too much mischief while in their animal form.
