One common element is the exploration of the bonds between characters. In Naruto, friendship and rivalry are strong themes, and fanfictions often expand on these. For example, the relationship between Naruto and Sasuke is a popular one to explore, whether it's about their reconciliation or their epic battles.
The use of ninja techniques and the development of new ones is also common. Writers like to imagine how characters could combine jutsu or create entirely new ones. This adds an exciting element to the fanfictions as it allows for creative battles and power - up scenarios.
Another common element is the creation of new story arcs. Since the Naruto series has a large and complex world, fanfictions can introduce new threats, new villages, or new mysteries that the characters have to face. This keeps the Naruto universe fresh and interesting for readers.
A common element is the unique weapons themselves. These can range from swords with special chakra - enhancing abilities to shurikens that can track targets. Another element is often the struggle of the weapon maker to gain recognition or protect their creations. For example, they might face competition from established weapon - making families.
One common plot element is the early access to the Sharingan. Since Naruto is born an Uchiha, he usually gets the Sharingan much earlier than in the original series. Another is the change in his relationships. His bond with Sasuke becomes different as they are now clan - mates. Also, he often has to deal with the Uchiha clan's secrets and history, which was a big part of Sasuke's story in the original but now becomes Naruto's too.
In 'naruto x crossover harem' fanfictions, a frequent element is the adaptation of Naruto's abilities in the new crossovers. His ninja skills need to be adjusted or combined with the powers of the characters from other universes. Also, the harem usually has a diverse set of personalities. There might be the shy type, the strong - willed type, etc., which creates interesting dynamics as Naruto navigates his relationships with them. The fanfictions also often have a plot centered around protecting the new combined world or achieving a common goal that brings all these characters together.
In these fanfictions, a very common element is Naruto's enhanced strength and abilities. He may be able to traverse between the living world and the afterlife at will. His moral code might also be put to the test as he rules over hell. There could be a lot of focus on his interactions with the denizens of hell, be they former foes or new characters created specifically for the fanfiction. Moreover, there may be a backstory about how he came to be the 'godlike naruto king of hell', which often involves some sort of epic journey or transformation.
One common plot element is Naruto's growth. In these fanfictions, as Naruto gets older, he often gains more power and influence, which attracts the female characters to him. Another element is the relationship dynamics. There are usually different types of relationships, from friendship to romantic interests, among Naruto and the female characters in his harem. For example, some girls may be initially rivals but then become friends or more.
One common element is the exploration of a different world. Since it's an alternate dimension, the fanfictions usually describe unique landscapes, cultures, and power systems. For example, there might be strange creatures or different ways of using chakra. Another element is the development of Naruko's character. She often has to adapt to the new environment and face new challenges, which leads to her growth as a character.
Another element is often the discovery or inheritance of a special sword. In many of these fanfictions, the sword has some connection to genjutsu, either it can amplify genjutsu or has its own genjutsu - like abilities. For example, it might be able to create illusions on its own when swung. This adds an interesting aspect to the story as the character has to learn to master both the sword and its genjutsu - related features. Moreover, there is usually a training arc where the character hones their skills. They might face various challenges during training, like dealing with powerful genjutsu that they need to break free from in order to progress in their swordsmanship. This helps in character development and also makes the story more engaging as we see the character grow and become stronger.
A common element is the display of Naruto's heroism. He is always ready to sacrifice himself for Hinata. Another is the emotional reaction of Hinata when Naruto gets hurt. She usually becomes very determined to either avenge him or protect him further. Also, the other characters' reactions, like Naruto's friends coming to help after he's injured while protecting Hinata, are often included.
One common element is the crossover aspect. Since it's a fanfiction combining Naruto and My Hero Academia, there's usually a way for the Naruto characters to enter the MHA world or vice versa. Another is the harem setup itself. There are multiple female characters, often from both series, who are attracted to the main male character, whether it's Naruto or a character inspired by Naruto. Power - ups are also common. The main character might gain new abilities or combine the powers from both universes in these fanfictions.
One common plot element is the use of Uzumaki's sealing jutsu. Since the Uzumaki clan is known for their sealing abilities, in these fanfictions, they often use seals to either trap the threat or protect Naruto while rescuing him. For example, they might create a barrier seal to keep the enemies at bay.
