Captain EO is the titular protagonist of the 1986 3-D film/theme park attraction Captain EO. EO is the captain of a ragtag spaceship crew of aliens and robots, sent on a mission by "The Corps" and Commander Bog to deliver a gift to the Supreme Leader. His gift is the song "We Are Here to Change the World," which he performs with his crewmates to unlock the villainous Supreme Leader's inner beauty and bring peace to her planet. He gains his power through the music, allowing him to transform the Supreme Leader, her minions and her planet. EO and his crew succeed and perform "Another Part of Me" as they bid the newly-peaceful Supreme Leader farewell and take off into the depths of space.
