With the 31 Primevals defeated and their sinister plan to zonderise the universe thwarted, it seems humanity is finally safe from alien evil-doers. In this time of inter-stellar peace, the Gutsy Galaxy Guard is battling the crime syndicate BioNet and their mysterious Q-Parts technology until Mamoru, son of Cain, suddenly returns to Earth! Things become confusing, however, when Mamoru attacks the GGG orbital base and steals their acquired Q-Parts. Why is Mamoru now fighting against his old friends? And could a new, even more powerful alien threat be behind all this?
In the distant future, far from the time of the great war and defeat of the alien invaders, the original Getter Robo team is back and continuing the fight against evil. The world is in ashes, and the invaders are back and in full control. Using their powerful transforming Getter Robots, the team's mission is twofold: to vanquish the robotic army of invaders and to discover the mystery behind Shin Dragon, the artifact left behind by Dr. Saotome, the now dead inventor of the Getter Robot; or IS he?
GaoGaiGar Final, just like Getter Robo Armageddon is a super Robo show where it goes about guts, fighting spirit and combining vehicles to create awesome Mecha's.
Though Getter Robo Armageddon could have been more it is still a awesome show filled with cool and interesting fighting scenes much similar to those in the GaoGaiGar series. I would really recommend watching Getter Robo Armageddon if you like GaiGaiGar.
