Some primordials might be quite surprised. In the Percy Jackson fanfiction, the modern interpretations could give them new outlooks on themselves. For example, if they are depicted as having more human - like emotions or motives, it could be a shock. However, they might also appreciate the fresh perspectives that make them more relatable to the modern readers.
Among the main characters besides Rimuru are Gobta. He is a goblin who is rather comical at times but also shows growth throughout the story. Then there is Diablo, a very powerful demon who becomes Rimuru's subordinate. His power and knowledge contribute to Rimuru's rise in the world of the novel. There are also other characters like Milim, a dragonoid with a child - like personality who has her own impact on the overall plot.
Milim Nava is an interesting character. She is a powerful Demon Lord with a child - like personality. She often gets involved in Rimuru's adventures in unexpected ways. Then there's Shion. She is a hobgoblin with great loyalty to Rimuru. Her over - the - top reactions and her growth in strength and character add a lot of fun to the story.
There's Veldora. He's a powerful dragon sealed within Rimuru's stomach at first. His presence has a great impact on Rimuru's growth and the story. Then there's Shion, a strong ogre who becomes one of Rimuru's loyal followers. She's known for her combat abilities. Also, Benimaru, a kijin, is an important character. He plays a key role in the development of Tempest.
He would probably be quite amused by some of his past antics. For example, his constant pranks on Iruka-sensei. But at the same time, he'd also see the pain he carried from not having his parents and realize how that influenced his actions. He might react with a bit of regret for some of the stupid things he did out of loneliness, but also be glad that those experiences made him who he is today.
Rimuru is very strong in the manga. He starts off with some unique abilities and keeps getting stronger through different events and encounters. His strength is not just physical but also in his strategic thinking and leadership skills.
Since I haven't read this particular fanfiction, it's hard to say for certain. However, given that Percy is often involved in heroic and dangerous situations in the original stories, perhaps in this fanfic he's facing new challenges from primordial entities. And the 'lemon' could be a creative addition that gives a different flavor to the story, maybe a strange object or concept that Percy has to figure out.
Since it's a fanfiction about Percy being raised by the primordials, it might show how Percy's values are influenced by these primordial entities. For example, if the primordials have a more primal or different moral code, Percy might have a different perspective on things like good and evil. The story could also deal with his relationships. He might have a difficult time making friends or finding allies because of his strange upbringing. Additionally, the fanfiction could explore the power dynamics between Percy and the primordials. Are they controlling him? Or is he able to break free and become his own person?
Well, in this fanfiction, it could be that the author wanted to explore a different side of Percy's character. Being the 'Father of the Primordials' might mean he has the power to shape the very essence of the world in this fictional universe. It might also lead to some really interesting plot twists, like how he interacts with the existing gods and demigods, and how they react to his new - found status. It could also introduce new enemies or allies based on his role as the progenitor of the primordials.
