He-Man is the hero of Masters of the Universe, the 1980s animated series that turned a toy line into a cartoon phenomenon. Its bold theme music became shorthand for strength and heroism, and short clips of it later spread through meme edits, reaction videos and workout montages online. Because the melody is instantly recognisable even without lyrics, creators still use it to turn an ordinary moment into an epic entrance, leaning on decades of nostalgia for the character and his catchphrase-like heroic image.
