Norbert the Nutjob is the chief of the Hysteric tribe. He is the son of Bigjob and a genius inventor. He is an arch enemy of Hiccup and owns a double headed axe that decides the fate of his prisoners. Norbert has a great dislike towards Camicazi too, ever since she had a swordfight with him and knocked him out with his own potato, and has tried twice to kill her.
