A leech-like Space Beast sent by Ahames to attach itself to Gyodai and control him. With Gyodai under his control, he makes the creature go on an eating rampage on Earth, using him to build up nutrients for itself to get strong enough to face the Changeman in combat. (and strangely allowing for it to make it seem like Gyodai could talk) After Gyodai eats a missile shot at him by the military, Kiga briefly abandons the plot seeing as it would explode within his stomach within 2 hours taking him and a massive area with him, but miraculously the Changeman are able to get the missile out of his stomach before the chemical reactions made it set off. Once the missile was removed, Kiga returns to Gyodai to complete his evolution, then combats the Changeman through firing colored orbs and objects
