Kingdom Hearts began in 2002 as a Square Enix action role-playing series that brought Disney characters and worlds together with Final Fantasy elements, creating a distinctive blend of fantasy, friendship and adventure. Its bright interface sounds, musical cues and magical effects became part of the series identity across its many sequels and spin-offs. Online, short clips from the games are widely shared by fans for edits, reaction videos and nostalgic compilations, keeping the audio recognisable even for viewers who have never played the games.
