Pokemon began as a Nintendo and Game Freak video game series in the 1990s, and its battle theme has accompanied trainer battles ever since. The short, looping track was designed to raise tension during turn-based fights, and as clips from the games spread online, fans began reusing it outside gameplay. Today it works as shorthand for any competitive moment, from gaming streams and reaction videos to meme edits, because listeners instantly associate its urgent rhythm with a fight about to begin.
