Well, a cool idea in Naruto Omnitrix fanfiction might be the idea of different ninja clans trying to steal or use the Omnitrix for their own purposes. The Uchiha clan could see it as a way to gain more power and avenge their past, while the Hyuga clan might be interested in how it could enhance their Byakugan abilities.
One interesting concept could be how the Omnitrix interacts with the unique chakra system in Naruto. Maybe it could transform the user into Naruto characters with added alien abilities from the Omnitrix. For example, turning into Naruto with the powers of Heatblast, allowing for a super - charged Rasengan with fire - based attacks.
In Naruto Omnitrix fanfiction, an exciting concept could be the training of a character with the Omnitrix. Since Naruto characters are often shown training rigorously, having the Omnitrix would add a whole new dimension. They would need to learn how to control the alien forms, combine their ninjutsu with the powers of the aliens, and also deal with the potential drawbacks or side - effects of using the Omnitrix in a world full of ninjas.
In 'naruto omnitrix bloodline fanfiction', a cool concept might be the exploration of different bloodlines through the Omnitrix. Maybe a character discovers a way to unlock hidden bloodline traits within the forms available in the Omnitrix that are related to Naruto's world. This could open up new storylines about heritage and power.
One interesting concept could be exploring new alien forms that the Omnitrix can transform into. Maybe there are some hidden or rare aliens that Ben discovers in the fanfiction.
Some fanfictions might explore the idea of a Fem Omnitrix having unique features. For instance, it could have an enhanced ability to transform into female - only alien species. This could lead to new adventures and storylines. Additionally, the fanfiction could focus on how the female character's identity is affected by having the Omnitrix. She might struggle with the power and responsibility in a different way than Ben, which would add depth to the story.
In some Omnitrix fanfiction, there are crossovers with other universes. For instance, a story where the Omnitrix wielder ends up in the Star Wars universe. They have to use their alien forms to survive in this new and very different environment, facing off against Sith Lords and using their powers in creative ways to interact with the Force.
One interesting concept could be an exploration of Naruto's dark side. It might show how his experiences could have turned him truly evil, like if he had been more influenced by the hatred in the ninja world from the start. Maybe in this fanfiction, he uses his powers for self - gain rather than for the good of the village.
In 'naruto dark naruto fanfiction', the concept of Naruto's doppelganger or 'dark Naruto' is often explored. This could be a manifestation of his repressed negative emotions. It might be that this dark Naruto has its own goals that are contrary to the real Naruto's. For instance, it could want to destroy the Hidden Leaf Village instead of protecting it. And the story could revolve around how Naruto deals with this inner darkness, either by trying to suppress it or, in a more extreme version, merging with it and becoming a different kind of hero or anti - hero.
In Naruto fanfiction, the Sharingan is often explored in unique ways. For example, some fanfictions might expand on its ability to not only copy jutsu but also to predict an opponent's moves on a whole new level. Another interesting bloodline concept could be the Uzumaki's massive chakra reserves, and fanfictions may play with how this could be used in different scenarios, like creating entirely new jutsu.
Some fanfictions might explore the idea of Naruto befriending an Espada. This friendship could lead to Naruto learning about different ways of combat and power management from the Espada. It could also result in the Espada having a change of heart due to Naruto's positive influence, and together they could face new threats in the Naruto universe that neither could face alone.
One idea could be a story where the Omnitrix is fused with a Pokeball, allowing the protagonist to transform into a Pokemon and use its powers while also being able to capture other Pokemon in a unique way. Another could be a cross - over where characters from Ben 10 (where the Omnitrix is from) end up in the Pokemon world and have to use the Omnitrix to survive and understand the new environment. A third idea is a story where a Pokemon trainer discovers an ancient Omnitrix - like device that gives them the ability to transform into rare and powerful Pokemon forms that no one has ever seen before.
One interesting storyline could be about Ben exploring new alien forms that were previously unknown in the official series. Maybe he discovers a form that has unique powers that he has to learn to control quickly to face a new and powerful enemy.
