The criminal organization BioNet stole one of the Q-Parts being researched at CERN, which has high regenerative properties. The Gusty Galaxy Guard appointed Guy Shishioh to work with his half cousin Renais-Kardif Shishioh and biologist Papillon Noir in Paris, France. Debuting with the new Super Mechanoid, GaoFighGar, Guy alongside GGG managed to defeat one of BioNet's agents and retrieve the Q-Parts. However amidst of their victory, a pale colored Mamoru Amami appeared after a year of his departure...

Upon the appearance of Mamoru, he then stole one of the Q-Parts as he collects the rest of them, either by guile or by force, and assembles them into their full form, a matter replication device known as the Pas-Q Machine. In the process, Papillon is killed, and Guy takes off after Mamoru. The encounter ends in a battle between GaoFighGar and a copy of GaoGaiGar using Mamoru and a copy of Galeon as the core component. The battle ends in Guy's victory, and both Mamoru and Galeon are revealed to be replicants that dissolve into sand. The machine is promptly taken by a mysterious man with butterfly wings, and GGG prepares to take after him into space
