I think Hinata could be an ally. She has always been in love with Naruto and would not stand by while he is in danger from Dark Naruto. Additionally, Shikamaru is smart and strategic. He might see the threat of Dark Naruto to the village and decide to assist Naruto, using his intelligence to come up with battle plans.
In fanfiction, the Rinnegan is often depicted as more powerful than the Sharingan in many ways. The Rinnegan has abilities like the Six Paths techniques which can be extremely overpowered. For example, it can allow the user to control gravity, summon large creatures, and even revive the dead. While the Sharingan has its own set of cool abilities like predicting movements and casting genjutsu, it seems limited in comparison when it comes to the grand scale of power shown by the Rinnegan in most fanfictions.
In a fanfiction, the aliens could capture Naruto and try to study his unique abilities. The monsters then decide to rescue him because they realize his powers could be the key to defeating the aliens once and for all. The story could involve a lot of action as the monsters infiltrate the alien base to save Naruto.
Well, sometimes in 'naruto vs dark naruto fanfiction', a cool plotline is when Dark Naruto has some new powers that Naruto has to figure out how to counter. For example, Dark Naruto might be able to control shadows in a way that Naruto has never seen before. Or perhaps Dark Naruto has allied himself with a powerful dark force from outside the ninja world. Naruto then has to not only battle his dark self but also this new threat.
Naruto is a very curious character. If he watches RWBY fanfiction, he would likely be drawn into the story. He might be amazed by the technology in RWBY, like the advanced weaponry. Since he values friendship so much, he'd also be interested in the relationships between the RWBY characters. He could end up learning some new ways of thinking about loyalty and friendship from the fanfiction.
There are also fanfictions where Naruto is a bit more reserved in his reaction. He might be cautious because he's not sure if Sakura's feelings are genuine or if they are just a passing emotion. He then takes some time to test the waters and make sure that their new relationship is based on something real and not just a spur - of - the - moment thing.
One common theme is self - improvement. Both Sakura and Naruto are constantly striving to get better in these fanfics. For example, Sakura might be trying to improve her combat skills to be on par with Naruto. Another theme is friendship. Despite their rivalry, their underlying friendship is often explored. It shows that they can compete and still care for each other.
In a fanfic, Naruto might power up by having a spiritual awakening. He could connect with the spirits of past Hokages in a deeper way, gaining their knowledge and some of their power. This could enhance his existing jutsu and give him new abilities. Vegeta could power up if he were to face a near - death experience against Naruto. This could trigger a hidden potential within him, like a new type of Super Saiyan form that has unique abilities. He could also fuse with another Saiyan (if there were another Saiyan available in the fanfic's scenario) to create an even more powerful being.
One interesting concept could be the clash of different power systems. Ash has Pokémon with various abilities like Pikachu's electricity, while Naruto has his ninja techniques such as the Rasengan. Their encounter in a fanfic might explore how these powers interact. For example, Pikachu's electric attacks might disrupt Naruto's chakra - based techniques, or Naruto's clones could confuse Ash's Pokémon in battle.
It's really hard to say. Ash has his Pokémon, which have a wide range of powerful abilities. Pikachu alone is extremely fast and can deliver strong electric shocks. However, Naruto has his super - powered ninja skills. His Sage Mode gives him enhanced strength, speed, and perception. It would depend on the situation and how the writer wants to play it out.
