Earth Pollution Vice-Minister Hiramechimedes

Land Pollution Vice-Minister Hiramechimedes (害地副大臣ヒラメキメデス, Gaichi Fuku Daijin Hiramekimedesu, 15-) is Yogostein's subordinate and Gaiark's top tactical genius. Whenever inspired with a plan, the 3 lights on his head flash, with the ruler, sextant, and protractor on his body indicating the plan's greatness. In spite of being low ranked, Hiramechimedes is feared by the Engines, his victories against them making frightened husks of their former selves in his presence. However, on the day the Gaiark were expelled from Machine World, Hiramechimedes mysteriously disappeared during the fight only to resurface months later on the Human World to serve under Yogostein again after settling some loose ends. He has a screw which strengthens Ugatz. With his sword and blinding speed, he can perform the Equilateral Triangle Slash (正三角形斬り, Seisankakkei Giri?). His name is a pun on the Japanese word for "flash" (閃き, hirameki?) and "Archimedes" (アルキメデス, Arukimedesu?). A running gag with Hiramechimedes is that the Go-ongers, besides Renn, mispronounce his name.
