While previous antagonists in the Final Fantasy series were distant, cold, ruthless, and bent on their goals, Kefka is loud, short-tempered, maniacal, and destructive. His popularity among Final Fantasy fans, at least outside Japan, as an antagonist is rivaled only by Sephiroth from Final Fantasy VII. Kefka is known for his many one-liners, his final almighty appearance (which has become something of a tradition in the series), as well as his sociopathic hatred of everything in existence. Kefka's defining character trait is his laughter, a high-pitched whooping cackle. In large part because of his dark humor and jester attire, Kefka was also given the nickname "the psycho clown" by fans, with this eventually becoming official with his CollectaCard description in Theatrhythm Final Fantasy.
