King Dark (キングダーク Kingu Dāku, 21, 22, Movie, 32 & 35): A giant robot who served as the figurehead of the Government of Darkness, who was previously heard as the G.O.D. General Commander.

He reveals himself after Apollo Geist's destruction, mocking Kamen Rider X. He was able to fire lasers from his eyes, launch missiles from his fingers, exhale poison gas, and could use his large arms for swiping. In Five Riders vs. King Dark it is revealed he can revive kaijin. He was destroyed by a self-destruct function that Dr. Noroi activated before he died. 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.
