King Dedede

デデデ大王

The series' primary antagonist, who seeks to destroy Kirby at any cost. He claims to have ruled Dream Land for 300 years and remains vigorous, yet he is not actually regarded as a king. Although Dedede is greedy, scheming, and even outright sadistic—going so far as to state that people's suffering amuses him—no one has ever attempted to dethrone him, despite his threats against children. He is largely harmless, but his intense dislike of Kirby compels him to purchase monsters from Nightmare Enterprises and cause mayhem for the people of Dream Land.
He enjoys buying new "toys" and behaves like a spoiled child despite his age. Jealous of the attention Kirby receives, he initially wanted to annihilate Kirby, but later focuses more on trying to kick him out or simply make him look bad. He does possess a kinder, gentler side, though it only emerges in extreme circumstances. For instance, in the De-appreciation-day episode, he played a prank on Kirby that blew him up, leaving Dedede upset because he thought he had actually killed Kirby. In another episode, when a meteorite was going to hit Pop Star, he built a playground to make up for his mistakes.
