Fire! Photonic 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.

Mazinger Edition Z: The Impact!
Set in the near future, humanity enters another energy revolution following the discovery of Photon Power. Derived from the ore discovered under the foothills of Mt. Fuji, its intended use was to solve the world's energy problems with its unimaginable power. Seeking this energy is Dr. Hell, a madman craving world domination who with his subordinates Baron Ashura, Count Brocken and Viscount Pygman, commands an army of mechanical beasts excavated from the ruins of ancient Greece to seize the Photon Power Lab for himself. Meeting the attack head on is the hot-blooded teenager Kabuto Kouji, who pilots the Photon Powered robot built by his grandfather, Mazinger Z. But in this battle between Dr. Hell and the Kabuto family, many legends surrounding the Mycenaean Civilization and Bardos Island, as well as the secrets of Mazinger Z remain shrouded in mystery.
A new series based on the mecha show that started it all, Mazinger Z. Shin Mazinger Shougeki! Z-Hen starts over from the beginning with a new cast, to tell a new story unrelated to the original show.
