Great Star League Gozma is the main villain organization of Dengeki Sentai Changeman. It was founded by Star King Bazeu and comprised of various aliens whose homeworlds he conquered. They are all forced to serve Bazeu lest he complete the destruction of their planets.
By the end of the series, most of the members of Gozma have either rebelled or turned against Bazeu. When Bazeu got killed, Gozma died along with him.
