Rubeus Hagrid was born to a wizard father and a giant mother, making him a half-giant. He is the gamekeeper and groundkeeper of Hogwarts as well as the Professor of "Care of Magical Creatures" classes. As a half-giant, Hagrid possesses great physical strength and endurance, including a resilience against some spells, though his ability to withstand spells is not as great as that of full giants. He is about twice as tall as an average man, standing at eleven feet, six inches tall (too big for an ordinary-sized broomstick) and three times as wide, with a long mane of shaggy black hair and a beard that covers most of his face. Hagrid's hands are as big as dustbin lids and his feet in their boots are like baby dolphins. He has dark eyes that glint like black beetles. Hagrid's size often makes it difficult for him to enter rooms or buildings that are designed for ordinary sized people or not built with airy or grand designs. He often wears an exceptionally large moleskin overcoat with several pockets. Hagrid is an incredibly warm, kind-hearted, intelligent, perceptive man, and often forgets his exceptional size and strength when patting people on the back. Another of Hagrid's greatest traits was his courage. He is also very loyal to his friends and is ready to defend them or fight for them if necessary. He is particularly loyal to Albus Dumbledore, describing him as a "great man". He would react with fury if anyone dared insult the headmaster and wouldn't hesitate to magically assault or rough up the offender. However, despite his loyalty, Hagrid is not good at keeping secrets. Hagrid has a great love of magical creatures, including cross-breeds such as the Blast-Ended Skrewt, and has a better relationship with most of the inhabitants of the Forbidden Forest than most people, including the centaurs. Unfortunately, he tends to overlook the dangers behind certain magical creatures. Despite his gentle nature, Hagrid was still sometimes known to be aggressive, especially when people insulted or dishonourably attacked those he cared about. Despite this, Hagrid was a very sensitive person and was known to burst into tears when someone close to him was harmed or killed, or when he felt responsible for something that put his friends in peril.
