==Synopsis==
==Plot==
The stage show opens with Shocker Leader's voiceover which talks about Japan being divided into three regions of which are Hokuto, Touto, and Seito. He mentions that the ensuing chaos from the wars enacted over the Pandora Box has given Shocker a great opportunity to rise again and take over Japan. Shocker Leader then wishes Ika Devil and Garagaranda to succeed. Ika Devil then talks to the Shocker combatmen about how their activity has been at an all time low and reminisces about the old days of Shocker at its prime. He then pushes the question of why is Shocker doing terribly now and selects a random Shocker combatmen to talk about the happiest moment in his time serving Shocker. The Shocker combatmen answers with being happy to be paid to walk around patrolling the perimeter of the base. Ika Devil scolds the combatmen by saying that is not what Shocker is about and recounts how Shocker has been reduced to appearances on music shows, commercials, and talk shows. He talks about how Shocker shines brightest at the appearances in movies every year, but this year there were no phone calls to come back. He then confesses his fears about getting shut down due to a lack of appearances. Garagaranda suggests that the best way to come back is by creating a new Shocker Kaijin that can defeat any enemy, calling the endeavor Super Kaijin Project. He also reveals that their newest Shocker Kaijin is getting infused with Nebula Gas so that they could be even stronger. However, Garagaranda reveals that they are running out of energy needed to continue the project in which Ika Devil suggests that the Pandora Box is needed. He then finishes up by telling the other Shocker combatmen present that they need to get the Pandora Box in order to further the plans of Shocker.
The scene then shifts to three Shocker combatmen with lab coats and colored headbands: pink, gold, and green. They talk about how the Super Kaijin Project sounds difficult, but gets interrupted by a live broadcasting of Mii-tan called Mii-tan-net. Just when the broadcasts gets to the part where Miitan announces her request to her audience, it gets interrupted by Garagaranda's emergency orders to move out on Touto's government complex to take the Pandora Box. Frustrated that their broadcast was interrupted, the three combatmen decide to alert Touto's Kamen Rider by posting a "rumor" on Mii-tan-net about the upcoming Shocker invasion. Then they break out into a dance routine to the song of Be the One alongside the other Shocker combatmen as background dancers. 
Touto's symbol now flashes across the screen with alarms blaring followed by an explosion indicating Shocker's breach of the government building. Sabotegron who is leading the charge, orders the Shocker combatmen running around the audience to find the Pandora Box. Sento Kiryu and Ryuga Banjou then appear to halt Shocker's capture of the Pandora Box. They then transform, Sento as Build RabbitTank and Banjou as Cross-Z Magma. They encounter Sabotegron leading a group of Shocker combatmen, but confuse them as Nanba foot soldiers. Banjou and Sento split up to take down the Shocker kaijins. The camera cuts to Banjou knocking out many Shocker combatmen and starts claiming that his power is unbeatable. This leads Sabotegron to try out an experiment on him. Banjou soon encounters Gentoku Himuro as Kamen Rider Rogue stopping his advancements. The two duke it out for awhile, but a Shocker combatman interrupts the battle to give Banjou a "soy bean protein drink" that supposedly gives energy. Banjou then drinks the whole bottle only to gag in realization that he actually consumed a full bottle of soy sauce. Now weakened by soy sauce, Banjou succumbs to Rougue's finishers and gets captured by Shocker. Before exiting off stage, Banjou comments how Gentoku already betrayed Touto and Seito, so it was only a matter of time before he betrays Shocker. Ika Devil and Garagaranda reappear on stage to congratulate Gentoku and his involvement with Shocker with Gentoku stating that he has no intention of serving under Shocker's Leader. Sento appears on stage only to learn from Ika Devil that the Pandora Box has been taken and that Banjou will be used as a test subject for Shocker's latest Kaijin. 
Now inside of Shocker's laboratory, the camera cuts to Sabotegron leading the three Shocker combatmen with lab coats and colored headbands, instructing them to construct a weapon as part of the big project. As soon as Sabotegron leaves, another broadcast from Mii-tan-net appears on the screen. She announces her request of wanting to know the location of Shocker's secret HQ in order to take back the Pandora Box. The three Shocker combatmen with headbands were so moved by her request that they sent over the GPS, phone number, address, and map image of where Shocker's HQ is. Just as they nervously await the idealized arrival of Mii-tan herself, they instead encounter Kazumi Sawatari. He then changes into Kamen Rider Grease and attacks the three Shocker combatmen with colored headbands. Shocker with a gold headband manages to interrupt the battle by accidentally pulling out a Mii-tan fan in self defense in which Kazumi exclaims that Shocker is so great they found out his only weakness. However, all four of them realize that they are fans of Mii-tan and stop fighting each other in order to celebrate together over the discovery of another friend fan. The three Shocker combatmen starts acting more like the Hokuto Sanbagarasu from in series. Build appears to interrupt their gushing display of affection over Mii-tan and wonders what they are all up to. He then starts doing a three question pop quiz to assert what Kazumi is supposed to be doing at the Shocker HQ. Suddenly, more Shocker Combatmen begins to appear in which the three with headbands helps hide their newfound friends. After the other Shocker combatmen leave, the three with headbands starts a self introduction. Gold headband Shocker is named Kon and used to work as a NASA engineer. Green headband Shocker is named Midorida Ivsky and he used to live in Roscosmos in Russia. They then switch to a gag about Russians in which the three with headbands act out a skit making jokes and puns. Pink headband Shocker finishes introductions off by saying that their name is Pinky and that he got scouted as an assistant by Kon and Midorida at a Mii-tan offline event. Sento gets distracted by a hazard trigger lying on a "workbench" (stairs) and finds out from the three Shocker combatmen that it was the Hazard Shocker Trigger, part of the latest project. The three studied the Kamen Rider battles so much that they were able to make an improved stronger Hazard trigger than the one Takumi Katsuragi designed. An alarm starts blasting with Garagaranda announcing that the Shocker Super Kaijin Project was only one step away from completion. Kon, Midorida, and Pinky realize that this must be related to the capture of the new prisoner for experimentation in which Build interjects that he wants to rescue Banjou who was the one captured. The three Shocker combatmen pledge to support the heroes in which Kazumi calls their operation "Rescue Banjo and Pandora Box Recovery".
The scene shifts to Ika Devil speaking to Sabotegron, Garagaranda, Banjo, and several Shocker combatmen that the project is nearing its final steps.
