Power - building is a common theme. The OC usually starts off with some sort of special ability or knowledge and uses it to gain more power in the Highschool DxD universe. This power - building often attracts the attention of various female characters, leading to the formation of the harem.
I'm not sure if there is such a specific fanfic available online. Fanfics can be quite diverse and hard to track down, especially with such a specific and rather unusual title. It might be a very niche creation within a particular fan community.
One popular 'godlike naruto massive harem fanfiction' is 'Naruto: The Harem King'. It has an interesting plot where Naruto is given god - like powers and attracts a large number of female characters. The story also has some exciting battles and character developments.
There's also 'Rising of the OC in DxD'. In this fanfiction, the OC is a reincarnated being. He uses his past - life knowledge to his advantage in the world of Highschool DxD. His harem includes characters from different factions, and the story delves into how he manages to keep them all together while facing various challenges from the supernatural world.
In the Naruto fan community, the focus is mainly on the epic battles, the growth of Naruto and his friends, and the complex lore of the ninja world. Fanfictions that are centered around something as unusual as 'Massive Cock Naruto and Kaguya' are likely to be a very fringe part of the fan - created content. While there is a vast array of fanfiction exploring different aspects of the Naruto world, this particular concept seems more of an oddity that might not gain widespread popularity compared to more common themes like alternate endings or different character pairings.
It depends on different groups of fans. Some might be interested in this kind of fanfiction as it offers a different take on the Naruto universe with a harem concept. However, the 'lemon' aspect, which often implies sexual content, may not be appealing or acceptable to a large number of fans, especially those who are more interested in the original story's themes like friendship, growth, and ninja adventures. So, overall, it's not a genre that can be considered widely popular among all Naruto fans.
In 'naruto massive chakra fanfiction', a really cool concept could be the combination of different chakra natures in ways that are not seen in the original series. For instance, combining fire and water chakra to create a new type of energy that has both the offensive power of fire and the adaptability of water. This can lead to really unique battle scenarios and character abilities.
Often, characters with huge amounts of chakra are considered powerful. Naruto himself might be even more powerful in fanfiction, with his already massive chakra reaching new heights. Sasuke could also be a top - tier character, his Sharingan combined with a large chakra reserve making him a force to be reckoned with.
You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. These sites have a large collection of Naruto fanfictions involving Kaguya. Just use their search functions and type in relevant keywords like 'Naruto Kaguya' to find some great reads.
Well - developed characters. If the fanfiction delves deeper into Kaguya's character, perhaps showing her more human side or her motives in a more complex way. And for Naruto, it could show his growth in a new and interesting light, like how he adapts to dealing with Kaguya in a non - combat scenario. Also, good character interactions between them, such as intelligent conversations that reveal more about their personalities.
