Star King Bazeu is the main antagonist of the Dengeki Sentai Changeman, appearing as a giant blue limbless torso floating out in space. He is the leader of Gozma, an army of aliens who travel through space conquering and destroying species. His forces are almost entirely made up of the champions of the planets he's conquered, who are forced to serve him lest he finish the destruction of their planets.

The final episode of the series reveals that the blue limbless torso he appears as is an illusion and that his true form is a planet-sized creature known as Gozma Star (Japanese: ゴズマスター Gozumasutā). It is also reveals that he survives off consuming planets becoming more powerful with each world he devours. He was finally destroyed when Change Robo blew up his core.
