Well, it depends on the specific fanfic. Some fanfic authors might choose to write a story where Midoriya has a hard time controlling One for All at first, but through various challenges and character development, he gradually gains better control. Others might give him immediate and effortless control for the sake of a different kind of plot. So, there's a wide range of possibilities in fanfics regarding his control of One for All.
Yuki would definitely be affected. She has a close relationship with Zero, and his loss of control could put her in danger. Also, she would be emotionally distraught seeing Zero in such a state.
Ace could be an anti - hero in the 'ace loses control fanfiction'. They have their own set of beliefs and values which might be different from the mainstream. Losing control could be a turning point for their character arc, either making them more of a villain or pushing them towards redemption depending on how the story unfolds.
No, it is not appropriate. Writing a story with such a theme about a mother 'losing control' in an improper or unethical way can be disrespectful and violate moral and family values.
The theme of power and its misuse or unexpected use is also present. Hermione is known for her intelligence and control over magic. But when she loses control, it shows how power can be unpredictable. It might also touch on the idea of how she regains that control and what she learns from the experience in terms of handling her own power more effectively in the future.
One possibility in 'ace loses control fanfiction' is that Ace loses control of their actions in a moral sense. They might be influenced by a dark force or a mind - controlling entity. This could make them do things that are against their normal character, like betraying their friends or engaging in unethical behavior. The story could then focus on how Ace tries to regain control and redeem themselves.
Percy himself, of course. And his close friends like Annabeth would probably be there. She's always been by his side and would be likely to try and help him when he loses control. Grover might also be in it, as he's another important friend of Percy's. He could use his nature - related abilities to try and soothe Percy or help in some way.
Well, it could be about Percy losing control of his powers. Maybe he's in a really tough situation, like facing an extremely powerful enemy, and the stress makes him unable to handle his powers properly. His friends would then have to step in to help him regain control and deal with the consequences of his out - of - control powers.
One common way is through intense training montages. The fanfic might show Midoriya pushing his physical limits to better handle the power of One for All.
