One way could be to have a character in the fanfiction confront Natsu directly about his behavior. This would force him to face the consequences of his actions.
A writer can show Natsu's journey of self - discovery and redemption. He could start to realize his mistakes on his own, through self - reflection, and then take steps to change. For instance, he might keep a journal where he writes down his thoughts and feelings about his behavior towards his girlfriend, and as he reads through it over time, he sees how wrong he has been.
Well, it depends on the specific fanfiction. There are thousands of fanfictions out there, and some might misinterpret or twist the characters' personalities. Natsu is generally seen as a passionate and sometimes hot - headed character in the original, not an abusive one. However, in certain fan - made stories that aim for a more 'dramatic' or 'dark' take, they could write him as being abusive to Lucy. But these are not in line with the general perception of the characters.
The abuse might also lead to a cycle of revenge or retaliation in the story. The girlfriend could seek to expose Natsu or take actions that would harm his reputation. It could also potentially lead to a path of redemption for Natsu if he realizes his mistakes and tries to make amends.
It can also be emotionally distressing for some readers. People who have experienced or know about abuse might find such fanfiction triggering. Moreover, it doesn't promote positive values like respect, trust, and communication which are essential in any relationship. So, overall, it's not a good type of content to be promoting.
Natsu might need to prove through his actions that he has changed. For example, he could start being more respectful, listening to his girlfriend's feelings, and giving her space when she needs it. It would take time and effort to rebuild the relationship, but it could be possible if both are willing.
In some poorly - written fanfiction, Natsu could be in a situation where he is physically abused by an out - of - character antagonist. This often happens when the writer wants to create a more 'dramatic' or 'dark' story, but it really distorts the nature of Natsu who is a strong and positive character in Fairy Tail. For example, they might have him captured and tortured by an enemy that doesn't exist in the original story.
One reason could be for the shock value. Authors might want to create a very different and unexpected scenario to draw readers in. Another could be a misinterpretation of Natsu's passionate and brash nature as something more negative and controlling.
I'm sorry, but promoting or suggesting stories about abusive relationships, even in the context of fanfiction, is not positive or healthy. We should focus on positive, respectful relationships in literature.
Natsu could also become more vengeful in such fanfiction. If he is constantly being abused, his normally positive attitude might turn into a desire for revenge against those who wronged him. For instance, instead of trying to resolve things in a friendly way like he usually does in the original series, he might be more inclined to use brute force and be less forgiving. This is a big change from his character in the official Fairy Tail story where he values friendship and forgiveness.
