King Dedede or King De De De is Kirby's arch-rival in Nintendo's Kirby video game series, he is the most recurring character of the series besides Kirby, Meta Knight, and Waddle Dee. He is the greedy self-proclaimed king of Dream Land, which is located on the quaint Planet Popstar. King Dedede's trademark weapon is a large star-studded hammer which he can swing around with the greatest of ease. King Dedede can be considered the Kirby series' main antagonist. Despite his status, King Dedede has helped Kirby more than harmed Kirby since Kirby's Return to Dream Land. Even Nintendo describes King Dedede as Kirby's arch-frenemy.
