Rubeus Hagrid
Giants in the "Harry Potter" universe are capable of interbreeding with humans – Rubeus Hagrid is half-giant, as is his love interest Olympe Maxime – but wizards as a population have engaged in an active campaign to hunt giants out of civilisation. The last giants in Britain were killed apparently by Ministry decree, but most deaths have been due to territorial aggression among themselves, as wizards force them to live in ever more confined spaces. The last few giants remaining in the world (the total number is between 70 and 80) are collected together in an isolated region east of Belarus. Giants range in height from twenty to twenty-five feet (6 to 7.5 metres), and have skin similar to rhinoceros hide, which grants them limited immunity to magical attacks. Their society is loosely governed by a chief called a Gurg, who spends most of his time demanding food from his underlings.
