"Your father and Sirius here were the cleverest students in the school, and lucky they were, because the Animagus transformation can go horribly wrong -- one reason the Ministry keeps a close watch on those attempting to do it. Peter needed all the help he could get from James and Sirius. Finally, in our fifth year, they managed it. They could each turn into a different animal at will."
-- Remus Lupin (PA18)

Animagus Transfiguration

The Transfiguration by which an Animagus takes his or her animal form, or reverts to human form from animal form. The animal form is sometimes referred to as the witch or wizard’s Animagus form.

See Animagi entry for further details about wizarding folk who can perform this highly complex and dangerous magic.
