Due to Harry's upbringing, Ron has to explain why the headmistress would be offended by the statement. "They're just vicious, giants," Ron states. "They're like trolls ... they just like killing, everyone knows that."

Dumbledore also trusted him to move the Philosopher's Stone from Gringotts Wizarding Bank to the school and believed Hagrid could offer Harry as much protection as "a bunch" of Ministry Aurors could while shopping in Diagon Alley, in 1996. [30] In 1995, Dumbledore gave Hagrid the difficult task of approaching the giant colonies of the North and dissuading them joining forces with Lord Voldemort, knowing Hagrid was fully capable of the delicate handling required to court the Gurg. [19] Upon Dumbledore's departure, general chaos reigned within the school, as the students became determined to make Umbridge's job as hard for her as possible; Lee Jordan even released a couple of nifflers into her office, for which she blamed Hagrid. Umbridge finally attempted to have Hagrid forcibly removed from the premises, and possibly arrested, when she brought several Ministry officials to his hut in the middle of the night so as not to cause a commotion with the students due to their earlier presence at Sybill Trelawney's dismissal. Hagrid refused to go quietly and took on the officials, whose attempts to Stun him proved fruitless thanks to his giant blood. Fang came to his master's aid until one of the wizards Stunned him, prompting Hagrid to lift the culprit bodily from the ground and throw the unfortunate soul ten feet away. I've come to accept the fact that Hagrid will never stop yelling." — Professor Snape on Hagrid's cheerful mood at his birthday party [src] Later on, Hagrid could not practice his magic often because he was too busy with his work in Hogwarts and also because nobody ever thought, of the people that knew about him having his wand repaired, to give him some help in exercising his magic abilities. That's why he could not turn Dudley into a pig and could only give him the tail.

Rubeus Hagrid: " Gettin' on well, aren't they? Fer the Hallowe'en feast... should be big enough by then." Harry Potter: " What've you been feeding them?" Rubeus Hagrid: " Well, I've bin givin' them — you know — a bit o' help —" Hermione Granger: " An Engorgement Charm, I suppose? Well, you've done a good job on them." — Hagrid's use of the Engorgement Charm to enlarge pumpkins [src] Though Hagrid was himself a supporter of magical creatures, he disagreed when Hermione decided to create SPEW. Hermione pointed out how unhappy Dobby was being with Lucius, but Hagrid also pointed out that other house-elves considered him to be crazy. No, sir — house was almost destroyed but I got him out all right before the Muggles started swarmin' around. He fell asleep as we was flyin' over Bristol." — Hagrid to Dumbledore on rescuing young Harry Potter in 1981 [src] May I just add that while we here at Potterwatch applaud Hagrid’s spirit, we would urge even the most devoted of Harry’s supporters against following Hagrid’s lead. “Support Harry Potter” parties are unwise in the present climate.’

We find out that Hagrid was expelled from Hogwarts, and his wand was snapped; we also learn that the pieces, apparently still functional, are hidden in his umbrella. Hagrid using this umbrella to perform magic is seen again in the next book.Mother: Fridwulfa, one of the last British giants; she abandoned the family when Hagrid was 3 years old ( GF23).
