Gormin, also referred to as Gormin Sailors, are silver humanoid robotic grunts who serve as footsoldiers for the Space Empire Zangyack. They are deployed from Zangyack ships using magnetic cranes and typically work in squads led by three Sugormin.
The Gormin first appeared on Earth in the Great Legend War. There, hundreds of them, led by dozens of Sugormin, fought against the past 34 Super Sentai teams. The Sentai teams put up a good fight and the Zangyack forces took a hard beating, but the Sentai Great Army's leader, Akarenger, noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.
When Hyuuga requested that Gai Ikari (GokaiSilver) give him the GokaiCellular, Gai envisioned him turning into GokaiSilver and defeating a group of Gormin. Basco ta Jolokia used a squad of Gormin, which were presumably provided by Damaras, to cause havoc across the entire city, in order to find Matsuri Tatsumi (GoPink) when she came to help so he could take the greater power of GoGo-V.
