King Dedede, also titled as His Royal Nemesis in Kirby Star Allies and written as King DeDeDe or King De De De in certain older games, is Kirby's arch-rival and the main antagonist and/or anti-hero in Nintendo and HAL Laboratory's long-running Kirby video game series. He or his likeness has appeared in every game in the series except Kirby & The Amazing Mirror. As such, he is the most recurring major character of the series besides Kirby and Waddle Dee. Nintendo has described Dedede as Kirby's "arch frenemy,"[2] and as he has helped more than harmed him since Kirby's Return to Dream Land, it is debated whether or not Dedede is the main (or even an) antagonist any longer.
