Sunshine appeared as one of the Devil Knights, a group of Akuma Choujin who had supposedly stolen the Golden Mask, a sacred relic on planet Kinniku that was once the head of a god. He fought Geronimo during the Five Story Ring battle within Warsman's unconscious body. Though he nearly killed Geronimo, he was ultimately defeated by his Apache War Cry technique after his weakness was discovered to be loud noises. Like the other Devil Knights, he was absorbed by Akuma Shogun before the fight with Kinnikuman.
