Pasdar gathers his Machine Kings and says it’s time for them to show their abilities. Mamoru’s class visits Tokyo Tower, but he can’t help but feel uneasy for some reason. At a train station, Polonaise takes control of several trains while Primada hijacks an entire highway of cars. Pizza eyes the supersonic jetliner HST and says that it’s perfectly suited for the blue skies. Back at Tokyo Tower, the parked Volfogg spots Penchinon sitting on a bench and gives chase, eventually arriving at subway entrance. The controlled trains and cars start emitting pillars of purple light that form a wall around Tokyo. Mamoru thinks it’s a Zonder but wonders why he isn’t sensing anything. Mass panic occurs in Tokyo Tower as people try to evacuate and Mamoru is unable to contact 3G due to jamming. He thinks that the Machine Kings are behind this as a Zonder metal plant starts forming around the tower. The plant starts grabbing the people inside the tower while everyone scrambles to get back up, and soon starts spreading to the entire enclosed area of Tokyo. Volfogg follows Penchinon down to a storm drain, and the latter suddenly jumps from the water and tells Volfogg that this will be his grave. He causes an opening in the tunnel and water floods in. Volfogg transforms to robot mode and uses his Jet Wrapper to drag Penchinon with him. The enclosed Tokyo area is then surrounded by four barriers as Volfogg surfaces in Tokyo Bay. He summons GunGlue to lift himself out of the water and spots the barrier enclosing Tokyo. Penchinon assimilates a frigate and becomes EI-27.
In the Big Order Room, Taiga explains that there are ten million civilians trapped in the barrier and all routes inside are blocked. Hyuuma asks if Mamoru reported anything and Mikoto says that he was on a field trip to Tokyo Tower so he’s trapped inside and all communications are jammed. Entouji says that there weren’t any Z0 particles detected. Guy asks Volfogg how he let this happen and the latter apologizes for falling into the enemy’s trap and leaving Mamoru. Taiga says that this will be their biggest operation and asks all the 3G robots to do their best. They watch footage recorded by Volfogg of the Defense Force jets approaching the barrier only to be instantly destroyed. Upon examining the footage from a different angle in slow motion they discover EI-26, which is Pizza merged with the HST jet. The 3G robots recall meeting the Machine Kings at Isolde and Leo remarks that if they’re directly involved now things will be more difficult. Mikoto reports that the Defense Force tanks are approaching the barrier. The tanks are lifted up by the barrier and destroyed. Swan reports the analysis of the barrier and dubs it the Contra Fall. The Contra Fall is made up of 4 layers of energy similar to what they’ve encountered before. The first layer is a high energy magnetic field similar to Isolde. The second layer is concentrated oxygen similar to the cloud Zonder EI-09. The third layer is a super dimensional pocket like the one caused by tire Zonder EI-17. The final layer is a Grand Nova like one caused by nanomachine Zonder EI-18, which prompts Guy to ask if everyone inside is unharmed. Entouji replies that the temperature inside the Contra Fall is normal so there’s nothing to worry about. Swan and Leo deduce that the Machine Kings must be growing a Zonder metal plant inside the Contra Fall, which could potentially mechanize all the trapped civilians. Kazou explains the plan of attack, which involves Guy, Goldymarg, HyoRyu, EnRyu and the Pliers creating an opening in each of the four layers while Mic and Volfogg distract Pizza and Penchinon. Entouji warns that they’ll only have a few seconds to go past the barrier once they start and Kazou adds that the point of entry will be the neighborhood of Hatsudai where the energy level is the weakest. Taiga orders the Brave Robot Corps to launch at once and put the plan in motion. Everyone arrives outside the Contra Fall and GaoGaiGar and ChoRyuJin are formed. Mic charges Pizza and tries to transform but fails again and gets flung into the ocean. Goldymarg fires at Pizza while ChoRyuJin clears the first layer with the Eraser Head. Penchinon starts firing shots from underground and Volfogg combines into Big Volfogg to confront him. Guy clears the second and third layers with the Dividing Driver and Dimension Pliers. ChoRyuJin and the Pliers then distract Pizza and Guy clears the last layer with the Goldion Hammer and finally penetrates the Contra Fall. Guy finds Tokyo raised from the ground and covered completely by the Zonder metal plant, with crystals about to bloom soon and Zonderize the trapped civilians.
With no more Zonder crystals to use, the Machine Kings are finally forced to get down n’ dirty and turn all of Tokyo into a metal plant. While the Contra Fall was a great strategy, the Machine Kings could have threw a few extra surprises into the recipe since all 3G had to do to circumvent it was to destroy each layer in rapid succession. Penchinon is ready to throw down one last time with Volfogg, who’s been a thorn in his side ever since he debuted. I only wish they had removed Mic’s block already because there’s little need for his comic relief failures at this point in the show.
