History
Tsubasa helps Koji fight against the invading Mechanical Beasts by giving him pointers about the Mazinger's strengths. She also comes face to face with her creations: Baron Ashura and Viscount Pygman. After Koji and Shiro move in, the Kurogane House is attacked by the Gamia Q and after they are defeated, Tsubasa notices that only a few scientists could make androids as advanced as the Gamia including Kenzo and Dr. Heinrich. With Dr. Heinrich in mind, Tsubasa travels to his castle in Germany. While there she encounters Shiro who had came with Heinrich's 'daughter' Lorelai. However, Dr. Heinrich used this chance to inform Shiro that Tsubasa is his mother and the one who killed his father. When Shiro asked, Tsubasa only replied that what Heinrich said was true. Shiro was frustrated at this revelation and ran off.

Later the castle is attacked by Baron Ashura and his Ashura Corps. to get a robot that Heinrich had promised Dr. Hell. Tsubasa had to evacuate as the castle was collapsing especially when the Mazinger fought against the robot, Danube α1. Afterwards, Tsubasa's relationship with the Kabuto brothers weakened after the revelation. But Tsubasa still assists Koji when the Kedora took over Mazinger and went to chase after it all the way to a pillar on Bardos where they travel to the past during the time of Zeus. As they are spotted by Archduke Gorgon, the Garadoubla MK01 was sent after them. As the Kurogane 4 fight it off, Koji and Tsubasa watch as Zeus and Hades battle it out only for the Garadoubla to come back and Koji activates Mazinger to fight it. After Zeus destroys Hades' body and Bardos begins to sink from Hades' new state, Tsubasa and Koji escape from the tower.

With the tower behind them, Tsubasa becomes sick from Viscount Pygman's powers and starts to hallucinate about Tetsuya. Later the Kurogane House is attacked by the Energer Z, piloted with who appeared to be Kenzo. Koji fought the Eneger with Mazinger but was starting to lose with 'Baron Ashura' demanding to know where Zeus' arm was while re-telling what happened on Bardos. She later figures out that Ashura was actually Pygman as the real Ashura was unconscious during the time on Bardos. Tsubasa then calls out Zeus' arm as it restrains the Energer. The Kurogane 5 then appear to capture Pygman with Tsubasa revealing she brought them back to life through her biochemistry skills. As Count Brocken ditches his Kenzo disguise as the Energer was about to blow up from colliding with Zeus' arm, Pygman escapes and tries to kill Tsubasa until Shiro shielded her, acknowledging Tsubasa as his mother. When Pygman is driven away, Tsubasa saw Zeus' arm become the God Scrander and combine with Mazinger to knock the Energer away as it exploded.

Even when the fight was over, Tsubasa still felt uneasy about the inevitable return of Kenzo as Dr. Hell had Koji challenge Baron Ashura and his Mechanical Beast. Koji is confused on what to do as his friends to him to and not to fight. Tsubasa helps Koji come up with a plan before he heads out. As Mechanical Beasts attack Atami, Tsubasa sets off explosives destroying several of them to help her son while Kenzo Kabuto appears to Tsubasa. Tsubasa then tried to kill him with a tanto, but Kenzo was revealed to only be a robot that was sent to guide Tsubasa to the real Kenzo. Kenzo reveals to Tsubasa that Dr. Hell had infected him with a Kedora and forced him to work for the mad scientist. Tsubasa forgives him as she returns to the Photon Lab in the form of the Photon Power Fortress. The new weapon appeared to give an advantage in battle but the Hell King Gordon absorbed their photon attacks. Kenzo had Gamia Q3 reverse the polarity of the Photon Power to damage the giant robot. As Koji and Mazinger prepare to attack, Kenzo tells Tsubasa with his last breath that with Dr. Hell's death will come the rise of the Mycenae Empire. Tsubasa tries to warn Koji but the Mazinger had already unleashed the 100 Rocket Punches they planned, destroying the Gordon and Dr. Hell. Unfortunately the Mycenae Empire rise to the surface after Baron Ashura performed a ritual. What happens then is unknown.
