A silver Space Gyaos (宇宙ギャオス, Uchū Gyaosu?) (in reality the repainted suit from Gamera vs. Gyaos) appeared briefly in Gamera vs. Guiron, a victim of Gamera's titular opponent. A swarm of Space Gyaos had attacked the planet Terra, an undiscovered planet in our solar system, being kept at bay only by the Terrans' guardian monster Guiron. After Gamera had killed Guiron, the planet was seemingly abandoned to the Gyaos. The Space Gyaos possessed similar abilities to their counterpart on planet Earth, however, the most notable difference was that direct exposure to sunlight had no adverse effect on the Space Gyaos.
