In my opinion, it's really hard to say who would win. Jason has his Roman powers which are quite formidable, like his ability to control the winds. Percy, on the other hand, has his water - based powers which are extremely powerful especially in the right environment. In a fanfiction, it could really go either way depending on how the author wants to write it. Maybe they could end up not really fighting but joining forces against a common enemy.
A great plot twist could be that they are both being manipulated by a third force. They think they are fighting each other for their own reasons but in reality, they are being used. Maybe a god or a powerful demigod is pulling the strings. This would lead to a moment of realization and then they would have to figure out how to work together to stop the real threat. Also, a plot twist where the Mark of Athena has a different meaning for each of them could be really engaging. It could be that Percy thinks it means one thing and Jason thinks it means another and their interpretations lead to a big misunderstanding before they figure it out.
It depends on the specific fanfiction. While the base material of Dragon Slayer might not have Levy as a Dragon Slayer, in the world of fanfiction, all kinds of alternate storylines are possible. Some writers may see her character as having the potential to take on this role and create a whole new set of adventures and relationships around it.
Makarov, the guild master, could also be present. He might see Levy's sleeping as a sign of the guild's youth and innocence. He could be reminiscing about the early days of the guild while looking at her sleeping form, and then make decisions about the future of the guild based on those thoughts.
It's possible that Levy is getting emotional. If the story has a touching plot, like a story of sacrifice or friendship, Levy, who values her friends in Fairy Tail deeply, could be moved to tears or have a warm smile on her face as she reads on.
Gajeel could be a great character to pair with Levy. Their relationship has always had an interesting dynamic, with Gajeel starting off as a bit of a rough character and Levy being more gentle and studious. Another option could be Lucy. They are both female members of the guild and could have a story together where they go on an adventure and use their different skills to overcome obstacles.
It can show her vulnerability. Levy is usually seen as a smart and capable mage in Fairy Tail. But in an embarrassing naked situation, her confidence might be shaken, revealing her more vulnerable side. For instance, she may become shy and reserved, which is different from her normal assertive self when dealing with books and knowledge.
This book was The Pirate Gun Code. The characters included the supporting role-Mark Madres, Li Wei's father, former rear admiral of the Navy Headquarters, the male lead-Mark Li Wei, sharpshooter Li Wei.
My dream is to travel around the world. The female lead is Nanako. The mother of the main character has a mysterious identity. The male supporting character is Eustace Kidd. He is Levi's younger brother. He was born in the South Sea and was adopted by Mark's family. The female supporting character is Andre Lorna. He is Levi's childhood friend. He is the female king of Luruta. He has the ability of Yunyun Fruit. This book can be read on Qidian Chinese website.
The Pirate Gun Code was written by Mu Dong, a layman. It was a light novel/derivative Doujinshi novel with transmigration and positive elements.
[User recommendation: Different from the One Piece Doujinshi Sword Hero Style, the main character uses a gun, and the younger brother is Eustace.] Kidd (anime character), slow heat, not brainless, original story.
It was different from the mainstream.
I hope you will like this book.
