"Pegasus Fantasy" (ペガサス幻想（ファンタジー） Pegasasu Fantajī) is a song by Japanese metal band MAKE-UP. Serving as the band's fourth major release single, "Pegasus Fantasy" and its B-side "Blue Forever" (永遠ブルー Eien Burū) were used as the theme songs for the first half of the original Saint Seiya anime. "Pegasus Fantasy" became MAKE-UP's most successful release, and they have re-released the song several times since its initial release in 1986. After releasing a "21st century ver." on their mini-album The Voice from Yesterday, MAKE-UP released a new edition of the song in 2012, subtitled "Version Omega", which features Shoko Nakagawa on guest vocals and is used as the opening theme song for the re-imagined Saint Seiya Omega anime. "Pegasus Fantasy Version Omega" reached number 29 on the Oricon's week
