Norbert is Norwegian Ridgeback dragon hatched from an egg by Hagrid, the Hogwarts groundskeeper, in the first Harry Potter book, Harry Potter and the Sorcerer's Stone. Norbert turned out to be too much for Hagrid, Harry, and his friends to handle, so he had to be smuggled out of Hogwarts to Egypt.

Norbert is just one of many dangerous magical creatures that Hagrid raises in the book series. Seems he has a soft spot for man eating, firebreathing monsters.
