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 created the battle suits used by Hammerhead and his Paradise Group, which they allowed to steal to collect real battle data. Once Hammerhead is defeated and the suits are destroyed, two members of The Organization come to finish off Hammerhead, and after attacking him left, believing him dead. However, Hammerhead survives because of his thick skull.
The Organization sends G4, a Machine God, to fight the S-Class hero King and to collect his data. However, instead of King, Genos fights G4 and defeats him. After defeating him, Genos sends G4's remains to Dr. Kuseno to be used for spare parts in order to upgrade his own 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.
