Pegasus Fantasy debuted in 1986 as the first opening theme for Saint Seiya, the anime adaptation of Masami Kurumada's manga about young Saints protecting Athena. Performed by Japanese band MAKE-UP with vocals by Nobuo Yamada, the song became inseparable from Seiya and the Pegasus Cloth. As Saint Seiya exploded across Latin America and Europe in the 1990s, the theme turned into a shared childhood anthem. Fans still share clips of its chorus for Saint Seiya edits and anime nostalgia posts, keeping the song alive decades later.
