The Homorphus Charm was described by Professor Gilderoy Lockhart as what he used to cure the Wagga Wagga Werewolf. He described the spell as being "immensely complex." He later admitted to having stolen the credit from an Armenian warlock.  It may possibly be able to force an animagus into their human form, like Sirius Black and Remus Lupin did to the rat animagus Peter Pettigrew in Harry Potter and the Prisoner of Azkaban.

Etymology

Homorphus is a combination of the Latin Homo meaning 'man' and the Greek morphe- meaning 'shape' or 'form'.
