2010, an evil energy being who names himself Drias comes to Earth, joining forces with Dr. Jango, a wicked scientist, in secrecy to bring ruin to the world - the Universe Security Force (宇宙警備隊, Uchū Keibi Tai) follows him to Earth and their members put their energy-formed spirits into either the special android vehicles built by Japan's scientist Hiroshi Amano (which have transformable bodies and were intended to be rescue units) or different service vehicles like an ambulance, a police car or a firefighter truck, all for the purpose of both concealing themselves from the eyes and ears of civilians and granting themselves matter-formed appearances for the feeling and touching of substances without their energies passing through such as ground or walls. Their commander, Fighbird, uses a human-shaped android created by Dr. Amano to enhance his invisibility from unintended eyes and ears and from then on lives as his artificial human-flesh-created android disguise Yutaro Katori. He transforms from his human identity when serious trouble strikes, and in the meantime he tries to adapt himself to living with Dr. Amano and his grandchildren Kenta and Haruka so he can interact with humans, learn more about Earth itself and put a stop to Drias' and Jango's plans for Earth and the Universe itself.
