 His character also alters significantly.In both the earliest materials and Geoffrey he is a great and ferocious warrior, who laughs as he personally slaughters witches and giants and takes a leading role in all military campaigns, whereas in the continental romances he becomes the "roi fainéant", the "do-nothing king", whose "inactivity and acquiescence constituted a central flaw in his otherwise ideal society".Arthur's role in these works is frequently that of a wise, dignified, even-tempered, somewhat bland, and occasionally feeble monarch.
