The theme comes from Mighty Morphin Power Rangers, the American television series that first aired in 1993 and adapted Japan's Super Sentai footage for a new audience. Its energetic rock sound became closely tied to the team's morphing sequences and battles, and the show's long run kept the tune in popular culture for decades. Online, it spread through nostalgia edits, reaction videos and gaming montages, where a few seconds are enough to signal heroism, teamwork and a dramatic comeback.
