Grawp is a giant who, although standing 16 feet tall, is short by giant standards. He is Rubeus Hagrid's maternal half-brother, making his mother Fridwulfa. Hagrid brought Grawp back to Hogwarts with him after his visit to the giants in 1995, mainly because the other giants were picking on him because of his height. Hagrid kept Grawp in the Forbidden Forest for months, teaching him manners and bits of English, and he seemed to have a particular affection for Hermione Granger. Grawp was rather violent over the course of the year; however, in 1996, he became more docile.
Grawp hid, along with Hagrid, in the caves near Hogwarts while Harry Potter, Ron Weasley, and Hermione searched for Voldemort's Horcruxes, and participated in the Battle of Hogwarts. As they could hear Voldemort's enhanced voice from their cave, they came to the battle as quickly as they could. Grawp lifted Hagrid into the castle, fought against the other giants (who were on Voldemort's side), and ultimately survived the battle. He disappeared initially when the first part of the battle ended but returned to fight the giants (and it was remarked that compared to the other giants he was indeed small) this time with the help of Buckbeak, the hippogiffs and the thestrals and he presumably defeated them.
Behind the scenes
- His name may come from all the other giants telling him to get bigger. When asked his name, he just responded what most people told him: Grawp (Grow up)
