The criminal organization BioNet steals one of the Q-Parts being researched at CERN. This episode serves primarily to introduce the changes to the main cast since the end of the series. Guy debuts in his new Super Mechanoid GaoFighGar, a combination of upgraded GaoMachines and the reconfiguring jet PhantomGao that was built to replace Galeon after the latter's departure from Earth at the end of the series.
