Grawp was Rubeus Hagrid’s half-brother, a giant whose mother was Fridwulfa. Grawp was small for his age and was abused by the other giants in their mountain stronghold. When Hagrid found him, he insisted on bringing Grawp back to live in the forest near Hogwarts. Grawp wasn’t too keen on the idea at first, but he is apparently getting used to it. Hagrid told Harry that Grawp was “loads better” towards the end of the school year (June Y16) (OP). Grawp fought on the side of the Hogwartsians in the Battle of Hogwarts (DH).
