A monster whose existence was confirmed in ancient times.
It disappeared after the SRC’s plan to capture it failed. This ferocious monster takes down its enemies with beams fired from the mouth and fire balls, and its sworn enemy since ancient times has been Lidorias, the Friendly Giant Bird.

After being awoken by Chaos Header, it came up to the surface of the Earth and started heading towards the city.
TEAM EYES tried to capture it with a laser net, but it destroyed it and tried to crush Tech Thunder 2, which had crashed.
Suddenly Lidorias swooped in and attacked Golmede, and they started to battle.
Golmede attacked one-sidedly with kicks and other martial arts moves. Musashi tried to save Lidorias with a flashbang, but this only served to annoy the monster, and it counterattacked with a fireball.

Ultraman Cosmos Luna Mode showed up just in time, and calmed the monster down with Full Moon Rect, but Chaos Header absorbed its power to create Chaos-Golmede, who immediately fired a beam at Golmede and defeated it.
