|Season:||Seijuu Sentai Gingaman|
A flea-like Majin who tried to find a heat source for the Daitanix's awakening. Rigurou can absorb the heat from people and locations, using the absorbers on the palms of his hands. This process would turn the people into frozen shells and the locations into frozen wastelands. Though he didn't wield a weapon, he could blast flamethrowers from the heat absorbers. He is killed by the GingaLeon's flaming breath after being thrashed by the other Starbeasts, including Gingalcon's tornado attack.
