King Dedede, also written as King DeDeDe or King De De De (in certain older games), is Kirby's arch-rival and a major character in Nintendo and HAL Laboratory's long-running Kirby video game series. He (or something in his likeness) has appeared in every game in the series except Kirby & The Amazing Mirror. King Dedede's trademark weapon is a large star-studded hammer which he can swing around with the greatest of ease.
