Star King Bazeu

Star King Bazoo is the leader of Gozma, and the main antagonist of the Dengeki Sentai Changeman, 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. Though claiming to control them, he constantly has betrayals at his forces, including two of his most notable generals, Giluke and Ahames plotting to assassinate him but failing to do so, leading to their separation on the invasion fronts.

Bazoo personally creates the Space Beast Warriors for his army, taking one member of a conquered race and mutating them with a beam emitted from his "head" even in hologram form.

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 the Change Robo deep onto his body and destroy its core.

Trivia

 * He is sort of like Unicron from the Transformer's Universe in the respect that his entire body is shaped as a planet (or in this case a star).
 * Bazoo's usage of Halley's Comet coincides with the perihelion of the comet in respect to the Earth on February 9th, 1986, which coincidentally were during the final weeks of Changeman's run on Japanese television.
