Stag Kikkaijin (クワガタ奇械人 Kuwagata Kikkaijin, 15 & 24): A stag beetle monster. His mission is to kidnap a scientist designing on an anti-gravity machine. Shadow later decides to cancel the project, using the man just as a lure to blow up Stronger in a self-destructing outpost. The monster can turn itself into a blue mist to travel through doors. He can fire an array of wire claw appendages to attack and both of his arms are giant claws. He was destroyed by Stronger's Stronger Electro Kick.
The Stag Kikkaijin was one of four dark cloak-wearing Kikkaijin that tormented a group of civilians in a nightmare induced on them by Kikkaijin Hasamigani while they were traveling on a locomotive.
