Mamoru’s class hasn’t been caught by the Zonder metal plant but is still stuck in Tokyo Tower. Sueo encourages them to not give up because 3G will save them and Reiko spots GaoGaiGar bursting through the Contra Fall. In the main order room, Mikoto can’t hail Guy and Kazou sends the Amphibious Armored Maintenance Vehicle to pick up Mic and the Pliers. Liger calls in and says that he’s bringing the best music for humanity’s future with him. Guy spots Polonaise and Primada powering the metal plant and Contra Fall by replicating a particle accelerator effect around a circular highway and railroad. He slams the Goldion Hammer into the intersecting point, sending them both flying off the tracks and disabling the Contra Fall. 3G spots the Zonder metal plant and Taiga orders all forces to concentrate on destroying it. Liger arrives and asks to borrow Swan for a bit. Pizza decides to go after Guy and ChoRyuJin gives chase. Big Volfogg tries to break off from Penchinon to rescue Mamoru but Penchinon blocks him with cannon fire and says he’ll never forgive him for always getting in his way. Guy tries to destroy Polonaise and Primada before they can regenerate but Pizza interferes and tells them to complete the metal plant. Polonaise and Primada get back on the track and reestablish the energy flow. Entouji reports that the Zonder crystals are still growing and will reach maturation in ten minutes. Goldymarg disconnects from Guy and tells him that he can’t match Pizza’s speed otherwise. Big Volfogg separates and has the Gun machines individually attack Penchinon. The latter is initially overwhelmed but quickly regenerates and bombards them with cannon fire. Volfogg remotely activates the Multi-Dimensional Intelligence Submarine and has it head to his location while Taiga orders Entouji to give him all the backup he needs.
Isamu arrives home just in time to catch Ai from fainting at the sight of the Contra Fall. Guy and Pizza fight, with the latter once again having the advantage of speed. Pizza boasts that Guy doesn’t stand a chance because he was born and raised in the skies. He knocks Guy around several times until Guy blocks his charge with Protect Shade and retaliates with Drill Knee. Pizza dodges that as a well as a Broken Magnum and hits Guy with his claw. Guy discovers thermals in the air and decides to use them to gain the advantage. ChoRyuJin fires at Polonaise but gets knocked off the track. Sunou panics some more and Reiko yells at him. Sueo suggests they cheer the 3G robots on and everyone joins in. Penchinon has the Gun machines defeated and rips off Volfogg’s arm just as the Multi-Dimensional Intelligence Submarine bursts into the tunnel. Penchinon begins assimilating it and Entouji detonates its reactor. Penchinon tries to escape but Volfogg pins him down and they both seemingly perish in the explosion. Pizza chases Guy and catches up to him when the latter suddenly slams right into him. Guy tells Pizza that he’s not the only who loves the sky and fires a Broken Magnum at point blank range. He then takes the chance to reconnect with Goldymarg and charge Pizza again. The latter tries to repel him with a wind blast but Guy hammers past it and disintegrates his body. With their energy depleted, Guy and Goldymarg collapse as the Zonder crystals reach completion. ChoRyuJin lures the speeding Primada onto his laid out tonfa and redirects her straight into Polonaise causing a massive explosion and cutting off the energy flow for good. Pasdar decides it’s time to finally show his power and Entouji picks up another Z0 reaction. Polonaise and Primada, battered but still alive, appear before the crippled ChoRyuJin. Primada says that they don’t enough energy to regenerate and charges ChoRyuJin in anger against Polonaise’s warning. The G-Stone inside ChoRyuJin reacts and bathes Primada in light. Polonaise extends a chain and tries to pull her back, but she barely has time to call him ‘dear’ before her body disintegrates. Polonaise mourns her loss and escapes leaving ChoRyuJin confused about what happened. Entouji says that this is the largest Z0 reaction they’ve seen and that all the Zonder crystals are complete. Mamoru runs towards the bottom of Tokyo Tower and stumbles upon Polonaise. Polonaise is too weak to escape and Mamoru purifies him. He changes into his human form and thanks Mamoru but tells him it’s late just as his body disintegrates. Mic flies over Tokyo and changes into Boom robot mode. He puts on Disc X and starts playing.
A great episode that’s much more than the sum of its parts. The Brave Robot Corps manage to take out all four Machine Kings at once, but Volfogg’s fate is unknown at the moment. While the individual battles aren’t very impressive on their own, together they form an amazing collage of nonstop action. Interestingly, the G-Stone seems to have a fatal effect on the weakened Zonderians, as demonstrated by poor Primada. Even more intriguing is the reveal that both she and Polonaise were normal humans who’ve been Zonderized for a long time and can no longer sustain themselves without the symbiotic relation with Zonder metal. Speaking of which, with the crystals now at full bloom and the 3G robots out of commission, it’s up to Mic to save the day with the mysterious Disc X that’s been hinted at by Liger for several episodes now.
