Mazinger Edition Z: The Impact!

The beginning shows a wrecked Mazinger Z slumbering away from the Dark General. This will be the continuation of Episode 26, where the Dark General comes and Mazinger Z uses the Big Bang Punch to ram the Dark General. The story moves back to the very start of the events which lead to the previous episode. Kouji and his brother, Shiro, are living with their grandfather, Juzo, while mysterious murders occur around their manor. Investigating these murders is Inspector Ankokuji, who was also hired to be Juzo's bodyguard, while Dr. Hell and Baron Ashura prepare for their first attack on the Photon Power Lab. In the meantime, Boss and his gang kidnap Shiro in order to lure out Kouji and beat him. After Kouji fights Boss, Baron Ashura attacks his household with the gigantic robot known as "Talos", forcing Juzo to send out the Pilder to Kouji and Shiro. Moments later, Juzo activates the product of years of research: the Super Robot, Mazinger Z.

Kouji gradually learns to how to control Mazinger Z, while Baron Ashura quakes in fear and rage at the robot who he/she believes to be Zeus (a being who "betrayed" his/her race, the Myceneans, thousands of years ago). After destroying Ashura's Talos with a devastating Rocket Punch, Baron Ashura vows to take revenge against "Zeus" by sending out two of its most powerful robots : Garada K7 and Doublas M2.

Kouji faces off against Garada K7, still struggling to use the controls. Meanwhile, Detective Ankokuji and Juuzou both attempt to flee from Ashura's troops, all while Juuzou suffers from a serious injury. As Kouji begins to move his fight with Garada K7 into the town of Atami, he manages to knock the mechanical beast into a building, only to see a horrific site: The blood of individuals who were crushed under the rubble. Traumatized and afraid of causing more casualties, Kouji attempts to fire a Rocket Punch, only for it to be deflected. Meanwhile, as Juuzou and Ankokuji are surrounded by Ashura's troops, Juuzou manages to enter a shrine (where Boss and his lackeys are hiding) in order to activate a remote control system, sending the giant fist out to catch both he and Ankokuji, returning them to Kouji and Shiro in Mazinger Z's cockpit.

As the battle with Garada K7 continues, Juuzou shows Kouji how to use the devastating "Rust Hurricane" attack, destroying Garada K7 instantly. Ashura then sends out Doubla M2, who begins to use Photon Energy attacks upon Mazinger Z. The attacks fail, however, as Mazinger Z is revealed to have been made from Super Alloy Z, allowing him to absorb the blast. Juuzou then teaches Kouji one last attack: The deadly "Breast Fire" technique, destroying Doublas with a blast of energy. Kouji, Shiro, and Ankokuji's rejoicing is short lived, however, as Juuzou dies moments afterwords. Infuriated, Kouji chases down Ashura in the Mazinger, grabbing him and nearly crushing him, before Sayaka and her comrades arrive to try and calm Kouji down. Ashura then escapes Mazinger's grasp, causing Kouji to let loose another Breast Fire attack, which Sayaka blocks using Aphrodai A. As Sayaka, and her father, Prof. Yumi, help Kouji to calm down, the plane carrying Prof. Yumi is destroyed by a new enemy: The headless Count Brocken, who deploys the bomber-robot Groizer X-10 to destroy Mazinger, and the rest of Atami. As the Mazinger Corps. fail to hold off Groizer's decent, Kouji and the others are faced with no escape. Suddenly, Tsubasa Nishikiori walks out towards Mazinger Z, telling Kouji that there is one weapon which he can still use: The Photon Beam.

Starting out approximately one day after the events of the previous battle, Kouji has been taken into custody by Ankokuji, while Shiro remains at the police station, as Ankokuji argues with Kouji about just how responsible he was for Atami's destruction. Meanwhile, Sayaka and the Mazinger Corp. have returned to the Photon Research Facility, and consider the sheer power of Mazinger Z, reflecting on Kouji's outburst the night before. Dr. Hell, Count Brocken, and Baron Ashura also reflect upon their previous defeat while on board the Flying Fortress, Ghoul. Later, Prof. Yumi tells Sayaka of his early work with Dr. Kabuto: Their discovery of Japanium, Juuzou's sudden disappearance, and the fact that he, in truth, chose to perform the Photon Energy tests in Atami in order to lure Dr. Kabuto out, so that they could complete their research together. Amidst these discussions, the story flashes back to the night before, continuing from the end of the previous episode, as Nishikiori tells Kouji to fire the Photon Beam. As Brocken's Groizer X-10 approaches, it begins to drop bombs on Atami, while Nishikiori instructs Kouji on how to operate the beam. With only moments before impact, Kouji charges the beam to its maximum capacity, and fires at Groizer, propelling it back into the air, and destroying it completely. Returning to the day afterwords, Sayaka and her father visit the Shirogane house, where Nishikiori explains her connection to Dr. Kabuto. Moments later, however, police officers sent by Ankokuji arrive, with a search warrant to look for the missing Pilder (which had vanished after the battle the night before). At the same time, Ankokuji demands that Kouji tell him where he hid the Pilder, while Kouji insists that he does not know. Meanwhile, Dr. Hell has a startling revelation involving his connection to Nishikiori.

As Ankokuji's search for the Pilder continues, Kouji continues to insist that he does not know the whereabouts of the craft. Despite this, Ankokuji plans to interrogate Shiro in front of Kouji, in order to force an answer out of him. Around this time, Shiro, who had been sleeping in the Police Department, wakes up to find the bodies of numerous officers. As a pair officers slowly approach the office to fetch Shiro, he overhears their plan, and is forced to hide, causing Ankokuji to send even more officers out to search for him. In the midst of all of this, Prof. Yumi and Sayaka become suspicious of Ankokuji's entire operation, noticing that the number of officers out searching for the Pilder far exceed those that would normally be present in Atami, and dispatches Sayaka in Aphrodai A. Shiro finds Kouji locked in his cell, before Ankokuji comes to attack them; as he lunges towards Shiro, Kouji grabs the detective's face, causing his "skin" to tear off. Meanwhile, group of officers at the Shirogane House make a shocking discovery: the REAL Detective Ankokuji has been sleeping at the Inn during this whole search, and the impostor who led this search is none other than Baron Ashura, with all of the "officers" being the Ashura Corps. Sayaka is stopped by another one of Ashura's machine beasts, Nonakargo H2, which quickly defeats Aphrodai A. Ashura manages to corner Shiro on the roof, but is thwarted by Nishikiori, who electrocutes it, while two of her subordinates, Yasu and Cross, break Kouji out of his cell. Seeing Ashura, Kouji grabs a soldiers sword and heads to the rooftop in order to avenge his grandfather. Meanwhile, Dr. Hell reveals his connection with Nishikiori to Count Brocken: she was previously his assistant, and the two of them had met with Prof. Kabuto and Prof. Yumi ten years earlier to find the legendary warriors of the island of Bardos. Multiple archeological digs took place throughout the Aegian Sea, but to no success. Eventually, however, the remnants of the island of Bardos were found under the sea by Kabuto and Hell, where the Mechanical Beasts lay dormant. Determined to use these beasts to rule the world, Dr. Hell was suddenly betrayed by Nishikiori, who blew the island up. Moreover, Hell reveals that Nishikiori is none other than the "creator" of Baron Ashura. Meanwhile, as Nishikiori prepares to deal the final blow on her creation, Kouji charges in, determined to kill it himself; this act, however, proves to be a mistake, as Ashura regains its strength and summons the Nonakargo to attack them.

Having summoned Nonakargo in the previous episode, Baron Ashura reveals its true ability - the machine can open up its torso and capture other machines with an electromagnetic net. Currently locked inside is Aphrodai A, the result of their confrontation in episode 7. As Ashura escapes and orders Nonakargo to capture Mazinger Z, Tsubasa tells Yasu to send out "the signal" in the form of a firework. This signal turns out to be the command to summon the Pilder, which was actually hidden underneath the Kurogane house, sending it (and Ankokuji, who fell on top) flying towards Kouji's location. Meanwhile, Boss and his cohorts who were originally planning to steal Mazinger Z decide to flee, since Nonakargo is approaching them. However, they're stopped by a strange new character in a sombrero, who is revealed to be another member of the Kurogane House - the sharpshooter Django. Django forces Boss and his group to help him fight the approaching Nonakargo on foot, by entrenching themselves in Mazinger Z's head and firing on it with a large rifle. The rifle turns out to fire special ice rounds, which freeze Nonakargo in place. Having bought themselves some time, Tsubasa and Kouji pursue Baron Ashura in the Pilder. It is then that Baron Ashura's origins were revealed - during the excavation of Bardos Island, Juzo and Dr. Hell discovered two lovers preserved within a cocoon, who Dr. Hell suggests should be revived from the dead to tell them the secrets of Bardos Island. Juzo points out that since half of the lover's bodies were decayed, they'd be impossible to revive - to which Dr. Hell suggests they be reborn as the same person. With his assistant Tsubasa's help, they successfully sew together the two lovers and bring them to life. Unfortunately, Ashura is immediately hostile to everyone in the room. To prevent this in the future, Tsubasa performs another surgery that will shock Ashura should he/she try to attack her or Dr. Hell - this is the source of her powers in the previous episode. Back in the present, Tsubasa catches up with Baron Ashura and tries to kill him/her with a missile, but is intercepted by the sudden arrival of Viscount Pygman, who is also subject to the same control as Ashura. He gets around this however by stabbing out his eyes, preventing him from "recognizing" Tsubasa. After blasting them with the missile, he flies off carrying Ashura and frees Nonakargo. With them out of the way, Kouji docks with Mazinger Z and attacks Nonakargo. After Aphrodite A frees herself from its electromagnetic net, he destroys it with a Breast Fire. The day then ends.

After a short time skip, Kouji and Shiro now live at the Kurogane House and work alongside the Photon Power Lab in the fight against the mechanical beasts. However, friction has been born between Kouji and the Robot Corps, who he finds useless and has no desire to fight beside. Meanwhile Baron Ashura, eager to prove him/herself to Dr. Hell, begins a co-ordinated mechanical beast attack on Tokyo, Osaka and Nagoya. At the same time, three mysterious blonde women arrive at the Kurogane House.
