There could be a fanfiction that explores an alternate universe where Noctis didn't become the king. In this story, he could be a simple traveler, exploring the world and helping people in different ways. He might use his combat skills to protect small villages from bandits, and along the way, he falls in love with a commoner and has to deal with the challenges of a different kind of life.
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. The author does a great job of portraying how Noctis reacts to the past events and how his actions in the past might change the future.
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.
You can start by looking on fanfiction platforms like Archive of Our Own (AO3). There are a large number of Noctis Lucis Caelum x Reader fanfictions there. Many authors share their creative works, and you can search using relevant tags to narrow down your options. Another place could be FanFiction.net, which also has a good collection of such fanfictions.
First, get to know the character really well. Replay the game, watch cutscenes, and read up on any official lore about Noctis. This will give you a solid base for writing him accurately.

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.
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.
One interesting Naruto Noctis fanfiction could be about a crossover where Naruto somehow ends up in Noctis' world. He might use his ninja skills to help Noctis in his battles. For example, Naruto's shadow clone jutsu could be used to confuse Noctis' enemies.
There could be a Noctis OC fanfiction where the OC is a skilled assassin who initially has a contract on Noctis but then ends up becoming his ally.

One idea could be Noctis arriving in the RWBY world and having to learn about Dust and how to use it in combat. Maybe he teams up with Team RWBY to fight against a new type of Grimm that his unique skills are well - suited to defeat.
