Star King Bazoo

Star King Bazoo (星王バズー Seiō Bazū): Bazoo is the leader of Gozma who only appears to his followers as a giant blue limbless torso, which is an illusion created by his true form: the living planet Gozma Star (ゴズマスター Gozumasutā) who absorbs other worlds throughout its interstellar conquest of the universe. Though he spares some planets, Bazoo uses them as a means to intimidate his minions with their destruction as both a drafting method and to ensure no failure. He manages to approach Earth undetected by hiding himself into the tail of Halley's Comet, but is ultimately destroyed by the Changemen after they ride Change Robo deep onto his body and destroy its core.
