Midoriya would initially be in shock. But then, his heroic instincts would kick in. He might try to analyze Toga's behavior and find a way to use it against her. For instance, if he notices that she gets distracted easily, he could create a diversion. He would also be thinking about the safety of others. He might worry that Toga has some bigger plan that involves harming his classmates or the city. So he would be constantly looking for a way to not only escape but also stop Toga's potential evil plans. And throughout all this, he would be drawing on his training at U.A. to keep his composure and think rationally.
Midoriya's family would be ecstatic. His mother would be busy helping with the wedding preparations, giving advice on everything from the dress to the food. Uraraka's family would be equally happy. They would see Midoriya as a kind - hearted and strong young man. Her mother would likely bond with Midoriya's mother over the wedding plans, and the two families would come together to celebrate the union of the two young heroes.
The other characters' reactions would be diverse. Bakugo might initially be very confused and maybe even mock Midoriya a bit, but deep down he'd still see her as a rival. Uraraka would probably be very empathetic and quickly become a good friend to Midoriya in her new form, helping her with things like getting used to the new body. And All Might would be very supportive, seeing it as just another obstacle Midoriya has to overcome in her journey to become a great hero.
Other characters' reactions can vary widely. Some of the more empathetic classmates, like Tsuyu, might offer words of comfort and stay by his side. Mineta might be a bit more cowardly, but still show some concern. The teachers, such as Aizawa, would take charge of the situation. Aizawa would ensure Midoriya gets proper medical attention and also start an investigation if the injury was due to foul play. His mother, if she were to find out, would be extremely worried and rush to be by his side as soon as possible.
Definitely not. Midoriya's character is very much alive in the manga. The creators have no intention of killing him off as he's a key figure in driving the narrative forward and inspiring other characters.
His closest friends like Ochaco Uraraka and Tenya Iida would most likely side with him. They have always been there for Midoriya and share his values of justice and doing what's right. Also, those heroes who have seen Midoriya's growth and believe in his pure intentions would probably join his side.
Midoriya's character development would be quite distinct. In his new form as a girl, he would have to re - evaluate his self - identity. He's always been a determined boy with a strong sense of justice. But as a girl, he might find that the world expects different things from him. This could lead to a struggle between his old self and the new self he's becoming. He might also develop a more nurturing side, which could enhance his hero capabilities in a different way. For instance, he could be better at calming down panicked civilians during a disaster. He would also have to deal with new forms of discrimination or assumptions based on his new gender.
Some popular Midoriya fanfics often explore his growth as a hero. For example, 'Midoriya's Hidden Power' which delves into him discovering a new quirk. Another is 'Midoriya and the Mentor', where he gets special training from an unexpected source. And 'Midoriya's Team - New Beginnings' focuses on his leadership within a new team formation.
