Северус Снегг
In "Half-Blood Prince", Harry inherits Buckbeak, and allows Hagrid to look after him again. To avoid suspicion from the Ministry of Magic, he is given the alias "Witherwings". A fiercely loyal creature, Buckbeak chases Severus Snape away from Harry by slashing his claws at the end of the book. Buckbeak also features in the Battle of Hogwarts at the end of "the Deathly Hallows" leading the Hogwarts Thestrals against Voldemort’s giants.
