Space Ironmen

The evil Space Ironmen (宇宙鉄人) are Machine Organisms (機会生命体) infused with Cosmic Energy created by the Alicia Federation (アリシア連邦). The Kyodain (キョーダイン) 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.

Groundain
Groundain (グランダイン) is the blue car-like older brother of the Kyodain. To begin his act of treason against humanity, he rushes to complete the military satellite weapon: the XVII. He is armed with a powerful cannon built into his chest called the Grounbuster X (グランバスターX). Groundain is an homage to Grounzel from Space Ironmen Kyodain.

Skydain
Skydain (スカイダイン) is the red jet-like younger sister of the Kyodain. Like her brother, she gains her own personality and wants to rebel against humanity. She is armed with built-in blades in her arms. Skydain is an homage to Skyzel from Space Ironmen Kyodain.

Black Knight
Black Knight (ブラックナイト) is the third Space Ironman created by the Alicia Federation who works alongside an agent from the Alicia Federation named Inga Blink. Unlike the Kyodain, Black Knight relies more on more defense than offensive attacks due to his strong armor. Black Knight is armed with a rapier called the Blackest Leaver (ブラッケスト・リーバー) and a machine gun built-in to his chest. Black Knight is an homage to the evil Black Knight of the Robot Army Corps from the Space Ironmen Kyodain series.
