The main features? Firstly, the rinnegan is a big deal. It can change Naruto's status in the Naruto world and how others perceive him. As for the harem, it's not just about love. It's also about friendship and loyalty among the harem members. These fanfictions may also feature unique story arcs that are related to the rinnegan and the harem. For instance, Naruto might have to use his rinnegan to protect his harem members from a common enemy, which would involve battles and strategic planning, all while dealing with the complex relationships within the harem.
A main feature is often the overpowered nature of Naruto with the godlike Rinnegan. His abilities are enhanced to a level that allows him to do things like effortlessly defeat powerful opponents. Another feature can be the exploration of new jutsus or techniques that come with this form of the Rinnegan.
One main feature is the combination of characters from Naruto and Bleach universes. Since Naruto and Aizen are from different shows, it creates a unique blend. Another is the harem element which usually involves multiple characters having romantic or strong emotional ties to Naruto and Aizen.
One interesting storyline could be the main character with the Godlike Rinnegan exploring different relationships within the harem. Maybe he uses his powers to protect the members of the harem from various threats in the Naruto universe.
Typically, Naruto himself would be a central character as he is the main protagonist of the Naruto series. Then there would be female characters from the Naruto universe who form the harem. This could include Sakura, Hinata, and maybe some other kunoichi like Tenten. The characters with rinnegan powers, such as Nagato, could also be involved in some way, either as a source of inspiration for the main character's rinnegan or as a rival.
The exploration of new storylines is also a big part of these fanfics. Since the Rinnegan is such a powerful and mysterious dojutsu, when Naruto is associated with it, it opens up a whole new world of possibilities. Fanfic writers can take the story in directions that the original Naruto series didn't go, like exploring ancient ninja secrets related to the Rinnegan that only Naruto can uncover now that he has it.
In certain fanfictions, the use of Rinnegan - powered time travel could lead to the discovery of hidden secrets in the Naruto world. As for the harem, the main character might find himself in situations where he has to protect multiple female characters during his time - traveling adventures. This protection and shared experiences could then lead to the formation of the harem. For instance, he travels to a time when the Akatsuki is more active and saves some female ninjas from their attacks, and they fall for him.
One interesting plot point could be how the rinnegan powers are incorporated into the harem dynamics. For example, the character with the rinnegan might use its abilities to protect the members of the harem. Another could be the relationships that develop within the harem due to the unique situation of the naruto universe and the presence of the rinnegan.
A key feature is the character crossovers. It brings together characters from Naruto and Borderlands, which is exciting as their personalities and abilities are so different. For example, Naruto's chakra - based powers against the gun - toting psychos in Borderlands. Another feature is the harem aspect. Usually, Naruto is at the center of the harem, and the relationships between him and the female characters from both universes are explored, often with a mix of romance, friendship, and sometimes rivalry.
The unique feature is the crossover aspect. Combining Naruto's ninja - filled world with the horror - filled FNAF world creates a very different and exciting setting. For example, Naruto's jutsu in the spooky FNAF locations make for some cool scenes.
I know a 'naruto rinnegan harem fanfiction' named 'Naruto: Rinnegan's Harem Quest'. In this story, Naruto's rinnegan gives him abilities that lead to unexpected encounters and relationships. It combines elements of adventure, mystery, and of course, the harem aspect. The character development is also quite good as Naruto navigates through his newfound situation with his harem members.
