Kirby is well known for his ability to inhale objects and creatures to gain their powers, as well as his ability to float by expanding his body. He uses these abilities to rescue various lands, including his homeworld of Planet Popstar, from evil forces and antagonists, such as Dark Matter or Nightmare. On these adventures, he often crosses paths with his rivals, King Dedede and Meta Knight, though Meta Knight can be seen as a hero, depending on the game. Kirby has been described as one of the most legendary video game characters of all time by PC World.
