Electromagnetic Mecha Iron Demon Dragon

Dragon Island, where once upon a time a dragon was supposed to have shown itself. Again an informant disappears who has been visiting and investigating this island. Is something there? Nambu thinks so, and according to his orders, the Science Ninja Team is mobilized. Before them appears the Iron Devil Dragon from Galactor. The God Phoenix is hit by an electromagnetic light ray and it's electrical systems are jammed. They are forced to return home for the moment. Concluding that it's impossible to attack head-on, Joe sneaks alone into Dragon Island. Pandora drives him there. Inside the Galactor base, Joe discovers a huge beam cannon pointing at the sun. In the meantime, Dr. Pandora has sneaked into the base on her own and has been captured. Joe sees her when she is brought before Gel Sadra, who is in the dragon. When meeting her, Gel Sadra says "You! It's as if I have met you before...". The dragon takes off, but Joe is already on board, after having set the base to blow. Joe rescues Dr. Pandora and together they destroy the generator for the electromagnetic waves. The Dragon can't use its electromagnetic waves now and the God Phoenix destroys it with its missiles.
