One interesting plotline could be their journey in starting a family. They might face challenges like Izuku's hero duties interfering with family time, but they work through it together. Another could be them renovating their first home as a married couple, with Ochako having creative ideas and Izuku using his strength to help.
Some fanfictions might include Uraraka's family members. Her parents could be involved in their married life, for example, giving Ochako traditional family advice. Also, Izuku's mother could be a prominent character, sharing her own experiences of being a single mother and now seeing her son happily married.
For Izuku, he might become more confident in his personal life. Marriage to Ochako gives him a sense of stability and he starts to show more leadership not just in hero work but also in his family life. He could also become more expressive of his emotions. Ochako, on the other hand, may develop a stronger sense of responsibility towards their relationship. She might be more assertive in her decisions and support Izuku in a more vocal way. For example, when Izuku is doubting himself in a tough hero mission, Ochako is there to boost his confidence.
The plot might involve Izuku and Ochako having to overcome some obstacles before getting married. Maybe there are some villains who target them because of their relationship, thinking that a married hero couple could be a big threat. So they have to fight these villains together and prove that their love is stronger than any threat. Once they get married, they might go on a honeymoon to a secluded place, like a small island. There, they can relax and just be a normal couple for a while, away from the chaos of the hero world. And when they return, they are even more determined to make a positive impact on the world as a married couple.
Well, their wedding would be unique. Since they are both heroes, they might incorporate elements of their hero personas into the wedding. Maybe the cake could be designed like one of Izuku's attacks or Ochako's Zero Gravity ability. The guests would include all their classmates from UA, and they would all share stories about Izuku and Ochako's time at school. The ceremony would be full of love and laughter, with Izuku and Ochako exchanging heartfelt vows.
One great izuku and ochako fanfiction is 'A New Beginning'. It shows their relationship development in a really sweet way. They face challenges together and support each other, and the author does a wonderful job of capturing their personalities.
One possible plotline could be Izuku having superhuman abilities that are not like the normal quirks in the original story. For example, he might have the ability to manipulate time or space in ways that are completely unheard of in the My Hero Academia universe. This could lead to him being both feared and revered by others.
One possible plotline could be Izuku using his knowledge of Pokemon to help him in his hero training. For example, he might study how Pokemon use their unique abilities and apply similar strategies in combat against villains.
One great fanfiction could be 'A Moment of Affection'. In this story, the kiss between Izuku and Ochako is a culmination of their growing feelings during a dangerous mission. They realize their true emotions for each other in the heat of the moment, and the kiss is described in a very tender and emotional way.
Well, in some fanfictions of this kind, Izuku as a girl might discover new aspects of her Quirk. Since the physical change could potentially affect how she uses her power. Also, there could be a plotline where she has to deal with romantic interests in a new way. As a girl, she might attract different kinds of attention from her male classmates, and she has to navigate through those new feelings and situations.
One possible plotline could be Izuku's struggle against the forced heroism, like trying to find his own identity within the constraints. Maybe he starts to question the true meaning of being a hero when it's forced upon him.
