The main characters could be a new generation of ninja students in the Naruto world. They stumble upon the knowledge of 'Nightmare Release' and have to deal with the consequences. This could include a young ninja who has a natural affinity for this strange power and has to learn to control it while facing the challenges from other ninjas who fear or want to use this power for their own gain.
Since it's a fanfiction about an orphan in Naruto, one of the main characters is likely the orphan themselves. It could be an original character created by the fanfiction author. There might also be some Naruto - universe regulars like Naruto himself, as he was also an orphan and could potentially play a role in the story, either as a mentor or a friend to the new orphan character.
It really depends on the specific fanfiction. However, it could feature Naruto himself dealing with a character who has the nightmare bloodline and trying to understand their motives.
Well, it could be about a whole new take on the Naruto universe. Maybe it involves a new jutsu called 'Nightmare Release' that has some unique and dark powers. It might center around a character who discovers this power and how it changes their life and the world around them in the Naruto setting.
Sometimes, the main character could be an established Naruto character like Naruto himself or Sasuke, but with a new twist where they somehow gain the ability to use light release. They would then have to learn how to control this new power and incorporate it into their existing fighting styles.
Another possibility is that the main character is a sensei or an elder in the ninja village who has knowledge about the Chaos Release. They guide the younger generation in understanding this power. In some fanfictions, it could be a group of characters, each with their own relationship to the Chaos Release, working together or against each other depending on their goals.
Well, it could be an original character created specifically for the fanfiction. This character might be an outcast because of their Darkness Release abilities. Maybe they are trying to prove themselves in a world that fears their power.
There could also be a villain in the fanfiction who wields plasma release in a menacing way. This character might be from a secret organization, using the power to further their evil plans. Their plasma - based attacks would be a major threat to the heroes, forcing them to find ways to counter this dangerous ability.
There might be a mentor - like figure who has some knowledge about the dark release. This character could be important as they guide the younger or less experienced character with the dark release. Maybe they have a hidden past related to the power as well. In some fanfictions, this mentor could be an old ninja who has seen the power's potential and destruction in the past.
It's hard to say for sure as it's fanfiction. But it could be an original character created by the fan writer who has the Mirror Release ability. Maybe it's also Naruto himself who discovers this new type of release during his adventures.
Obviously Naruto himself would be a main character. He would be the one to bring his ninja skills and determination into this strange combination of worlds. Sasuke could also be there, maybe as a rival who has different ideas on how to deal with the Gundam - related threats. And from the Gundam side, Amuro Ray could be a key character. He might be the one who first discovers Naruto and his group and has to decide whether to help or oppose them.
