Typically, they often feature a main character who was once a hero or had heroic qualities in a past life or situation. For example, they might have lost their status for some reason and are now on a journey to regain it or find a new purpose.
Sure. 'Sword Art Online' can be considered in a way. It features a hero - Kirito - who has to overcome many challenges in a virtual world. Another one is 'Overlord', where the main character was once an ordinary gamer but becomes an all - powerful being in a new world.
One main theme is self - discovery. The protagonist, after being banished, has to find his own path and identity outside of the hero's party. Another theme could be redemption. He might be trying to prove himself in a new way. And also friendship, as he may form new relationships away from his former comrades.
One possible plotline could be that Naruto mistakes a character from My Hero Academia as a threat to the ninja world. So, he banishes them to prevent any potential harm. For example, if he sees a powerful quirk user like All Might in the wrong context, he might think they are a new kind of enemy.
In this novel, the banished character often has to deal with the stigma of being cast out. They might encounter different situations that force them to re - evaluate their skills and values. For example, they could find that their abilities, which were perhaps undervalued in the hero's party, are actually very useful in other contexts. This can lead to all sorts of adventures and character development as they build a new life away from the group they were once a part of.
Perhaps the hero's values changed in a way that the society in the novel didn't accept. He might have started with noble intentions but as the story progressed, he became self - centered or greedy. This transformation would make the other characters in the novel, and even the readers, view him as a failure.
There might not be a large number of such very specific 'Naruto banished My Hero Academia' fanfictions. However, if you are into crossover fanfictions in general, you can also check out some Naruto and My Hero Academia crossover groups on social media platforms. Sometimes, members of these groups share their own written works or know of some that fit the rather unique concept of Naruto banishing someone from the My Hero Academia world. It could be a bit of a hunt, but it might be worth it if you're really interested in this idea.
One interesting aspect could be the character development. Characters who were once part of the hero's party now have to find their own paths. They might face new challenges and form different relationships outside the context of the hero's group.
