Obviously Naruto himself would be a main character. He could bring his unique ninja skills and his determination to the story. Another could be Noctis from Lucis Caelum. His powers and his role as a prince could add a lot of drama and action to the fanfiction.
Sakura could also be a main character in this fanfiction. She might be the one who first discovers the link between the two worlds due to her medical knowledge and her intelligence. And from Lucis Caelum, Prompto could be a main character. His cheerful nature could contrast with the more serious Naruto characters at times.
A really interesting plot could be that the ninjas in Naruto's world start to have dreams about Lucis Caelum. These dreams seem to be prophetic, and Naruto decides to investigate. Along the way, he meets a character from Lucis Caelum who helps him decipher the meaning of these dreams and together they try to prevent a disaster that is predicted to occur in both worlds.
A great fanfiction might focus on Noctis' relationships. Maybe a story that delves deeper into his friendship with Prompto. It could show their early days, how they became such close friends, and the moments that strengthened their bond. This could include things like shared secrets, late - night talks, and adventures they had as kids that are not shown in the game.
One great Noctis Lucis Caelum time travel fanfiction is 'A Journey Through Time'. It has an interesting plot where Noctis travels back to key moments in the history of his kingdom.

In a great Noctis Lucis Caelum x Reader fanfiction, the emotional connection between the two characters is palpable. It might include moments of vulnerability for Noctis, where the reader - insert can be there for him. The fanfiction could also incorporate elements from the game, like the use of magic or the different kingdoms in Eos. It should be a story that not only focuses on the romance but also on the growth of both characters within the context of the game's world.
The theme of self - discovery is also quite prevalent. In a new time period, Noctis has to re - evaluate who he is and what his purpose is. For example, in some fanfictions, he sees how his family's actions in the past shaped who he is in the future. And the theme of sacrifice often comes up. He may have to sacrifice something in the past to ensure a better future for his kingdom.

It could be Naruto himself. Imagine if he was reborn as a sennin. He would have all his previous experiences and then the added power and wisdom of a sennin, which would make for an extremely powerful and interesting character to follow.
Sasuke could also be a main character. His pursuit of power and his natural affinity for lightning - based techniques might lead him to be involved with the Lightning God power. He could either be a rival for it or a partner in harnessing its strength.
