Grawp

Grawp is the giant half-brother of Hagrid in the Harry Potter books.

First introduced in Harry Potter and the Order of the Phoenix, Hagrid brought Grawp from his mountain home to the Forbidden Forest oustide Hogwarts.

Grawp and Hagrid were born of the same mother, the giantess Fridwulfa ; Hagrid's father was a human, whereas Grawp's was a giant.

When he first appears in the Order of the Phoenix, Grawp is looked after by Hagrid, who keeps him tied to several trees in the Forbidden Forest. However, after Hagrid leaves Hogwarts to continue his work for the Order of the Phoenix, he leaves Grawp in the care of Harry Potter, Hermione Granger, and Ron Weasley. Much to their surprise, when they find themselves trapped in the forest during a confontation with the local centaur population, Grawp manages to divert the centaurs' attention from Harry and Hermione. And, when asked about him, Hagrid says something like getting Grawp a "lady friend".
