Kirby's signature skill is his ability to inhale objects or creatures and spit them out as projectiles, as well as the ability to suck in air to float over obstacles. His Copy Ability grants him the power to adopt the abilities of the creatures he inhales, while also wearing various costumes or transforming his shape. He uses these abilities to rescue various lands, such as his homeworld 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. In virtually all of his appearances, Kirby is depicted as a cheerful, innocent, and food-loving character.
