The series centers around the adventures of a pink round hero named Kirby as he fights to protect and save his home on the distant Planet Popstar from a variety of threats. The majority of the games in the series are side-scrolling platformers with puzzle-solving and beat 'em up elements.
Kirby was created by Masahiro Sakurai as the player character of the 1992 game Kirby's Dream Land (1992). The character's design was intended to serve as placeholder graphics for the game's original protagonist in early development and thus was given a simplistic ball-like appearance.
