It really varies. Sometimes a rewrite is needed to improve the story's flow, fix inconsistencies, or make it more marketable. But in other cases, the original version might be just fine as it is.
Madoka could be one of the main characters. She could interact with Steven, learning about his powers and his way of protecting the world. It would be interesting to see how her more somber and self - sacrificing nature would mesh with Steven's more upbeat and positive personality.
A really interesting concept could be the idea of redemption in a 'madoka magica x steven universe fanfic'. In Madoka Magica, there are characters who make desperate choices, and in Steven Universe, there is a strong theme of forgiveness and growth. Maybe a character from Madoka Magica who has made a dark choice could find a path to redemption with the help of the positive and inclusive ideology of the characters in Steven Universe.
There were a few novels that could be recommended. The first was " The City Sims ", written by Ming Jian. The novel told the story of the protagonist's life through a Sims system. He experienced, rewritten, and perfected his life in different dungeons. " I Can Rewrite My Life Script " was a story about the protagonist crossing into another parallel world and breaking the framework of reality by changing his life. In addition, Sun Wukong's Life Simulator was also an interesting novel. It told the story of Sun Wukong creating a future through the life simulator. These novels all had unique plots and creativity, suitable for readers who liked games to rewrite their lives.
In Madoka x Homura fanfiction, the power dynamics between them can be an interesting aspect. Madoka, as a very powerful magical girl, and Homura, with her time - looping abilities, have a unique relationship. Fanfiction could play with how they use their powers in relation to each other. Maybe in a fan - created scenario, they combine their powers to save a new threat that wasn't in the original series.
One popular trope is the 'time - loop fix - it' where Homura uses her time - looping abilities to try and create a perfect situation for Madoka. This often involves Homura going through multiple loops, each time learning more about Madoka and how to protect her better.
Another theme is time - related. Since Homura has the ability to manipulate time in the show, many fanfictions play with this concept in relation to her relationship with Madoka. For example, stories might involve Homura going back in time to save Madoka in different ways or dealing with the consequences of her time - traveling on their relationship.
