Rage, Shiro!! Shoot at Mother's Visage!!

"Death Match!! Revive Our Mazinger Z!!" (怒れシロー ! ! 母の面影を撃て ! !) is the 90th. This episode first aired in Japan on August 18, 1974.
==Summary==
Shiro is having a terrible time doing his homework. He’s supposed to draw his parents at work, but the fact both of them tragically passed away during a botched experiment is making the assignment bring out a lot of bottle up negative emotions. 
Misato enters the room to offer him snacks, but Shiro isn't having it. He throws a tantrum and decalres he won't do his homework. When Misato tries to comfort him, she only makes him more upset. Shiro accuses her of trying to replace his mother and storms off to cry in solitude.
Meanwhile, Koji is meeting with the scientists to plan their final attack on Hell’s Island. It’s decided that before launching the attack, all efforts should be focused on maintaining Mazinger Z to ensure it’s in optimal condition.
Back with Shiro, Sayaka learns about the situation from Misato and tries to cheer him up by taking him shopping. Shiro seems happy at first, but when he tries to convince her to take him out to eat, Sayaka angrily points out that he already made her spend all of her stipend. This enfuriates Shiro again, and he throws away the gifts, demanding she take them back.
Next, it’s Boss’ turn to try and comfort Shiro. He dresses up as a woman and offers to roleplay as Shiro’s mother. Predictably, this doesn’t go well as Shiro tries to break free every step of the way. Koji arrives just in time to see Shiro storm off once again, frustrated with yet another failed attempt to cheer him up.
Seeking solitude, Shiro goes to the beach. Seeing other kids happily spending time with their parents only sours his mood further. He plays pranks on the children, which leads to them ganging up and throwing mud at him, sending him away.
As Shiro watches the sunset, he hears a voice calling his name. He turns around and is shocked to see his supposedly deceased mother standing before him. She tries to hug him, but Shiro, confused, backs away. His mother brushes it off and tells him she won’t force him to accept her if he doesn't want her around. Shiro relents and follows her to her house.
Mrs. Kabuto explains that she survived the laboratory experiment. She speculates that the Photon Power Laboratory lied about her fate to protect its reputation after the disaster. Shiro asks if he can bring Koji to meet her, but the mood suddenly darkens.
Conflict and violence are always unnaceptable, Mrs. Kabuto expresses. She does not want anything to do even with her children if they're involved fighting against Dr. Hell and his Kikaiju. Shiro vows never to fight again, and this promise is enough for his mother to allow him inside her house.
They decide it would be best to reunite the entire family. Unfortunately, Ms. Kabuto doesn't believe Shiro will be able to convince Koji to abandon his violent ways and give up piloting Mazinger Z. However, she has a solution for that problem.
Ms. Kabuto hands Shiro a time bomb.
For them to live together, Shiro must destroy the Jet Pilder. That way, Koji won’t be able to fight anymore. Mrs. Kabuto warns that if Mazinger Z ever deploys again, she will disappear forever. Shaking with uncertainty, Shiro takes the bomb.
Later that day, a Kikaiju attacks. Just as Shiro finishes planting the bomb in the Jet Pilder, Koji arrives in the hangar, and the Pilder’s controls explode. Shiro explains to Koji why he did it, and Dr. Yumi suggests Koji confront Ms. Kabuto while he tries to repair the Jet Pilder.
Koji arrives at the apartment with the Photon Gun, expecting a fight. He is left speechless when Ms. Kabuto appears, looking exactly as he remembers her. Shocked, Koji hesitates, allowing his mother to knock the gun from his hand. A few words are all it takes for Koji to realize that this woman is an impostor. With the ruse exposed, several Iron Masks barge into the room to kill Koji.
After retrieving the gun on the terrace, Shiro is left alone with his mother, who followed him. She pleads with him to drop the weapon, but Shiro ignores her. Eventually, Shiro gathers enough resolve to shoot his mother, exposing her as a doppelganger.
With Shiro safe, Koji rushes back to the Photon Power Laboratory. He boards the repaired Pilder and, together with Sayaka and Boss, defeats the Kikaiju.
Afterward, Shiro watches the sunset again. This time, instead of lamenting his parents' absence, he assures them that he has grown from the experience and no longer feels alone, knowing that he is surrounded by friends who support him. As he turns around, he sees those very friends rushing to check on him.
