First, you should really know the characters well. Read up on their profiles, abilities, and personalities. Then, come up with a basic idea, like a new adventure for them or a different outcome to a known event. After that, just start writing. Don't worry too much about making it perfect at first.
I'm not entirely sure if there is a specific 'naruto is escanor fanfic' out there. It depends on the creativity of the fanfic writing community. Some writers might be interested in exploring how Naruto's personality and abilities would interact with Escanor's, perhaps in a scenario where they meet in a different dimension or something. But you'll have to do some searching on the major fanfic platforms to be certain.
Indeed, Escanor's death occurred in the manga. His fate was a significant plot point that had a big impact on the story. It was a poignant moment that added depth to the narrative.
One horror story could be running out of time during the LR section. You're frantically trying to answer the remaining questions, but the clock is ticking and you end up having to guess on a bunch of them. Another might be when you study really hard for a particular type of LR question, like parallel reasoning, but on the actual test, the questions are so convoluted that you can't seem to apply what you've learned. And a third could be getting a really difficult LR section right after a mentally exhausting LG section, and your brain just feels like mush and can't focus properly on the LR questions.
Naruto could use Escanor's power to boost his physical attacks. For instance, when he throws a punch, it could be surrounded by the sun's energy, making it more powerful.
The plot could revolve around a villain who is immune to Naruto's normal attacks but is vulnerable to Escanor's power. So Naruto has to fully embrace this new power source. Along the way, he might meet characters from Escanor's world who help him understand the power better. There could be a lot of action scenes where Naruto uses the power in creative ways, like using Escanor's 'Rhitta' weapon in combination with his kunai. And there could be a sub - plot about Naruto's friends being a bit jealous or worried about this new power he has.
One way to integrate Escanor's powers into Fairy Tail fanfiction is by having him participate in the Grand Magic Games. His 'Sunshine' power would be a show - stopper during the games. He could face off against strong mages like Laxus and use his sunlight - based attacks to counter Laxus's lightning magic.
Well, without more context, it's difficult to say exactly. 'Harry Potter is the elfling lr fanfiction' might imply that in this particular fanfiction, Harry Potter has some sort of elfling - related identity or role. It could be about exploring a different magical heritage for Harry, where the elfling aspect comes into play. For example, it might change how he interacts with magic, other characters, or the wizarding world in general.
