Crayon Shin-chan Movie 22: Serious Battle! Robot Dad Strikes Back In the begining, Shinnosuke and Hiroshi were watching the new Kantam Robot movie. It featured characters like Kantam Robot, his wife Sheila, their son Kantam Jr. and the mastermind Akogidesu. After watching the movie, they went out. Hiroshi gave Shinnosuke a ride on his shoulder. But then he gets a strained back. On their way home, they meet a mysterious lady called Omega Ranran who worked at a massage salon.

She is characterised by large breasts, which Shinnosuke imitates to tease Hiroshi. She talks with them, offers Hiroshi a free massage.

But only hiroshi was allowed to go

into the store. Hiroshi was forced to sleep by the lady, and was remodeled by a scientist.

Later, Hiroshi woke up and his body felt better. Meanwhile, Shinnosuke was telling about the lady's meeting with Hiroshi, and imitating the lady with large breasts.

Hiroshi then arrived at home and met his family, who were surprised on seeing a robot. Misae said ”who are you?”. They could not believe their eyes at first, but finally misae understood that the robot is Hiroshi.

But she doesn’t let him take into the house. Hiroshi had to sleep in shiro’s house. He realised that it had got to do something with the massage salon and the lady. Next morning they went to the massage salon. But the salon was vanished. So misae went to the Kasukabe Police Station. The chief Kuroiwa Jintaro ordered the police officer, Dandanbara Teruyo to find the lady

massagist who had vanished. But they couldn’t find. Nohara family lived a few days with Robot Dad.

One day Himawari kindergarten had a school trip to a river side building under construction.

Kasakabe Boueitai was forced to step up the elevator by a robot. But the top of elevator was nothing.

So they jump up and hung on a reinforced concrete, swinging in the

air. But the rope of reinforced concrete was cut off and they dropped into the air.

They were in a dangerous situation. Then Robot Dad comes and saves them all. With this, Nohara family accepted Robot Dad. While Misae was worried, Shinnosuke was overjoyed to have a Robot dad. The robot dad had a remote control by which he can be controlled.

Robot dad turns out to be very handy. He did cooking for the family.

He used his legs as grass cutters and hands as bush cutters, and did a wonderful job in gardening. He could clean grass with his legs.

His hands had many brushes.

He also repaired the TV antenna. He could do many things which human Hiroshi couldn't do. Shinnosuke used the remote to do him various actions, including the buriburi dance.

When the energy of the Robot dad was over, he had to be refilled from a hole in the Robot's butt.

Once Shinnosuke and Robot dad had an arm wrestling match. Shinnosuke

was defeated easily at first, but the second time Robot dad let him win as he didn't want to upset a child.

Misae once says emotionally that "whether you are robot or human, you are a father, one of the best fathers".

Once during dinner time, Himawari accidentally presses the two switches suggestive of the nipples, and two missiles were launched (but the house was not

blown off as shown in the trailer). Few days later, Shinnosuke met the lady, the same massagist, and she gives him a moustache, beard and hair. After he came back home, during dinner Shinnosuke let Robot dad put on the hairs. Suddenly Robot dad changes totally. He becomes a tyrant and rules his family.

Robot dad played with the kids in the park.

He worked at the office at a faster rate.

The next day robo Robot dad gathers all fathers in the park and drives out the tyranny mothers from the park. Then they march along the street, with banners in their hand.

Seeing that the changed Robo Hiroshi is out of control, Shinnosuke thought of putting back the former Robot dad. So Kasukabe Defense Group lead him to the back alley and attacked him.

Later, he was almost broken and treaded by Tekkenji Doukatsu, the leader of the Father's Alliance.

Robot Hiroshi was brought somewhere on the track, and Shinnosuke was chasing.

Then they arrived the factory, and Shinnosuke had only the head of Robot dad.

Shinnosuke lost his way and found a huge room where there were many robots which looked the same type as Robot Hiroshi.

So he put the Robo Dad’s head to a cleaning robot that looked like a Roomba. Robot Hiroshi woke up and shouted ”What is this body!? Where is my body?”. They went into another room. They found the real Hiroshi, naked and sleeping in the water ball. Shinnosuke pushed a button, and human Hiroshi woke up. They both said "Who are you?!" and claimed to be the real Hiroshi.

So Hiroshi and Robot dad quarrelled. Then they three were detected by Chichiyure Doumei (Father's union).

Robot dad is actually a robot in which Hiroshi's memory had been copied, so that he behaved like real Hiroshi. Hiroshi had not turned into a robot in reality. Then Robot dad finds new body, and they escape. They had known that the factory was the river side building. So they went home.

The fathers had occupied the police station. So Robot dad and Nohara family went there. Tekkenji comes out and battles with Robot dad.

After a serious battle, Robot dad wins and is pleased; he looks at misae. But Misae hugged Hiroshi the real human dad. Robot dad was disappointed.

Nohara family, Dandanbara and Robot dad were caught by Tekkenji. They came to know that Tekkenji’s real identity is Kuroiwa Jintarou, the chief police officer. Tekkenji was a robot controlled by Jintarou. Jintarou ordered Dr.Ganma to delete Robot dad’s the memory.

He decided to give devilish treatment to Shinnosuke. Robo dad cooked large serving fried green peppers, and forced Shinnosuke to eat them. Shinnosuke looked afraid but eats it all with courage. He

shouted “come back Robot dad!”. Hearing this, Robot dad came back to his original sense.

Tekkenji driven by Jintaro attacks them. The battle is fought once again. But the battle affects the building terribly and was breaking. They escaped and went outside.

Kuroiwa rode a new big robot named Itsuki Hiroshi (a famous singer). Then and Rob ot dad changed into big Robot dad. Shinnosuke and Hiroshi rode on it.

Then another fierce battle happened. They finally beat Itsuki robot.

After the victory, Robot dad said to Hiroshi ”Which one is the real Hiroshi? Let’s decide with arm wrestling.” The final battle began.

The battle was a heated one with both sides refusing to give up. In the end human Hiroshi beat Robot Hiroshi. It was decided that there can be only one Hiroshi. So Robot dad was broken.

Shinnosuke missed Robot Dad.
