The Organization (組織, Soshiki) is a secret organization composed of various robots. Their goal is to cause destruction and chaos and fight strong opponents to collect various combat data in order to increase the power of their robots.
The Organization allows Hammerhead and the Paradisers to steal battle suits made by them in order to collect battle data. Once Hammerhead is defeated and the suits are destroyed, two members of The Organization finish him off and leave, believing him dead. However, Hammerhead survives because of his thick skull.
The Organization sends Machine God G4 to fight the S-Class hero King and collect his data. However, King runs away, leaving Genos to fight the robot. After defeating G4, Genos sends its parts to Dr. Kuseno to be used for upgrades for his cyborg body.
Narinki takes armor The Organization developed and gives them to a squad to save his son. However, The Organization is in fact in cahoots with the Monster Association as they send their latest fighting robot, G5 to assist the Monster Association.
During his way to the Monster Association HQ, G5 manages to capture Narinki's mercenaries and hand them over to the Monster Association to be turned into foot soldiers by Do-S. G5 is holding the head of a Metal Knight Unit and calls it a valuable sample. G5 confronts Child Emperor during his attempt to rescue Waganma, but Child Emperor and Waganma manage to escape G5. G5 later encounters Atomic Samurai as well, and is defeated in the ensuing battle. However, his core escapes before it could be destroyed.
G5 later appears on the surface of the Monster Association HQ in the Z-City Ghost Town, interrupting Sekingar and Drive Knight's conversation. Before he could hurt Sekingar, however, Genos appears, and destroys G5 with a swift stomp.
