King Dedede

King Dedede, also titled as His Royal Nemesis in Kirby Star Allies, and written as King DeDeDe, King De De De, or King DDD (in certain older games), is Kirby's arch-rival 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. As such, he is the most recurring major character of the series besides Kirby and Waddle Dee. Due to his portrayal in various games as a villain, many believe that King Dedede is the main antagonist of the series. However, Nintendo has described Dedede as Kirby's "arch-frenemy," as he has helped more than harmed since Kirby's Return to Dream Land, which makes it debatable whether or not Dedede is the main (or even an) antagonist any longer.

He is the greedy self-proclaimed king of Dream Land, which is located on the quaint Planet Popstar. Due to an ambiguous description of the geography of Planet Popstar, it is never made entirely clear how much of the planet King Dedede assumes leadership of, though he seems to have castles and fortresses all across the planet. Even so, he seems to perform no administrative functions, and for the most part, the planet seems to ignore any edicts that are issued by him.
