The Great Star League Gozma is a ruthless galactic empire that devastates planets across the universe. After conquering a world, Gozma often forces surviving aliens into its ranks and uses them as warriors to invade even more planets.
This cycle of conquest turns victims into soldiers, making Gozma one of the most tragic and brutal enemy organizations faced by the Changemen.
Star King Bazoo is the supreme ruler of the Great Star League Gozma. He appears as a giant, imposing figure floating in space, commanding his forces through fear and intimidation.
In truth, Bazoo is a holographic projection of the living planet Gozmastar, the true center of Gozma's power.
Commander Giluke is the general placed in charge of the invasion of Earth. Originally from the planet Girath, he once plotted against Bazoo but was spared and given command of the Earth campaign.
After his death, he returns to terrorize the Changemen as Ghost Giluke, later becoming Super Giluke and eventually the Space Beast Warrior Giluke.
Booba is a former space pirate drafted into Gozma's ranks as a vice-commander. A dangerous warrior and ruthless fighter, he is armed with his signature heavy sickle, the Buldobas.
Seema is the princess of Planet Amanga and a vice-commander in Gozma's invasion force. She is cursed to speak with a deep, masculine voice while serving the empire.
She eventually breaks free from Gozma's control, regains her true voice, and defects to aid the Changemen.
Queen Ahameth is a rival commander from the planet Amazo who joins Gozma's campaign against Earth. Cunning, ambitious, and dangerous, she often operates with her own agenda.
She is accompanied by a fierce three-headed pet dragon, making her one of the more visually distinctive threats within Gozma's command structure.
Navigator Gator is the reptilian navigator of the Gozmard and comes from Planet Navi. He joins Gozma reluctantly to protect his family, serving the empire despite his reservations.
For the sake of his family and his own conscience, Gator eventually defects and sides with the Changemen for the remainder of the series.
Gyodai is a one-eyed monster-enlarging creature from Planet Gyodai. His name plays on "kyodai," meaning "giant."
When Gozma's Space Beast Warriors are defeated at human size, Gyodai enlarges them so they can continue the battle against Change Robo.
Hidrer Soldiers are the grunt foot soldiers of the Gozma empire. They are blue-skinned creatures with prominent bellies and blond hair, born from alien eggs and deployed in large numbers during attacks on Earth.
Space Beast Warriors are Gozma's primary monsters of the week. They are usually captured beasts from conquered alien worlds or alien survivors forcibly mutated into biological weapons.
The Great Star League Gozma commands a vast mechanical arsenal used to conquer planets and overwhelm planetary defenses.
