Kingdark (キングダーク, Kingu Dāku) is an antagonist that appears in Kamen Rider X, a giant robot who served as the major executive of the villain organization G.O.D..

Character history

Kingdark reveals himself after Apollogeist·Reborn's destruction, became the second major executive, and reorganized G.O.D.. He is often seen lying on the inner part of the hideout and in the pose of Buddha statue. He is permanently giant-sized, and is usually found in the pictured position in order to command his human-sized underlings. He was rather a laid-back villain always telling others to do the work for him and usually shrugs off failures.

He was planning to insert RS Device that converts all substances to energy, which was developed by Dr. Koichi Nanbara, inside his body and moving around. Dr. Nanbara, who has already completed the device, is afraid of its use and split the design diagram into 9 sheets. In order to retrieve the divided design diagram, Kingdark will continue to direct the evil army one by one to let the X-Rider in the battle, but he starts up without waiting for the incorporation of the device, and challenges the X-Rider.

In the final episode, Sasori Geronimo Jr. gets a design diagram of the RS Device's central part, completing the device and starts the plan for destruction of Japan. Finally, X-Rider managed to infiltrate into his body before a self-destruct function is activated by Dr. Noroi, blow up his body as well as Dr. Noroi who is in it.
