Shiranui Clan
2000 years ago the Yamato Clan and the Shiranui Clan were at war. The Yamato Clan won and the Shiranui Clan was banished underground. The Yamato Clan became the Japanese people. The Shiranui Clan became remained bitter and angry for 2000 years before 10 of its members broke the service to plot revenge against the Yamato Clan, using their giant humanoid robots. It does not appear thatThe Shiranui Clan knows who Iron King is as they are primarly concerned with killing Shizuka, Gentaro whom they consider the greatest threat to their plans, not Kirishima, Goro (who is actualy Iron Kiing).
Shiranui Clan Leader Shiranui, Taro (episodes 1-10)
He discovered (through spies?) that the National Security Organization
was aware of their plans and had sent agent Shizuka, Gentaro to stop them
and ordered his men to hunt down and kill this man.

None of the clan's troops are given names, the only other clan member who's name is mentioned is the school teacher Yoshiko, who thinks its crazy for people 2,000 years later to be fighting their ancenstors war and considers the Yamato Clan (the Japanase people) her friends and tries to keep her brother from answering the Shiranui Clan leaders call to arms. She is the only non-combatant Shiranui Clan member Gentaro and Goro meet.
Except for Shadow Ten each officer dies as his robot is destroyed, with each dying in the episode matching their number, until episode 6 In episode 6 Shadows Ten, Six and Seven are all killed. Shadows Eight dies in episode 7 and Shadow Nine in episode 8. With the death of Ten, control of the final robot has passed to Clan Leader Shiranui, Taro who control in episodes 9 and 10 and of course dies at the end of episode 10.
