Spoiler warning: Plot and/or
ending details follow.

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

Grawp is about 16 feet (4.8 metres) tall,
which Hagrid claims is small for a giant. His knuckles are the size
of a cricket ball (~225  mm in
diameter). Grawp was being bullied by the other giants, and this
was a factor in Hagrid's decision to bring him to the Forbidden
Forest. Big and dim, he only knows a few words in English and his
manners are wild and unpredictable. At first he seemed indifferent
to his brother's attempts to civilise him, preferring to spend his
time tearing down trees.

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.

In Harry Potter and the
Half-Blood Prince, Grawp is moved to the mountains, where he is
apparently progressing much better. He also attends Dumbledore's funeral with Hagrid, much more civil
and calm than before, and dressed formally.
