The evil Space Ironmen (宇宙鉄人 Uchū Tetsujin) are Machine Organisms (機械生命体 Kikai Seimeitai) infused with Cosmic Energy created by the Alicia Federation (アリシア連邦 Arishia Renpō). The Kyodain (キョーダイン Kyōdain) are the first two Space Ironmen created by the Alicia Federation who suddenly become activated and gain their own personalities. The Space Ironmen are an homage to the characters from the Space Ironmen Kyodain series, which was also created by Shotaro Ishinomori.
