While filming a sci-fi movie in the Caribbean two actors exploring ancient ruins discovered a mystic artifact which unleashed a monstrous demon called Nebiros.

Using a mechanical stunt suit for the movie as a weapon, stuntman Dan Cassidy defended the movie crew from the demon. In battle, Cassidy was blasted by mystic beams of energy which grafted the devil costume to his body making him a Blue Devil.
