Yes, often in such fanfictions, the plot can be quite engaging. The devil concept can be integrated in various ways. It might involve Percy being lured into a dark underworld ruled by a devil figure, and he has to use his wits and demigod powers to navigate through it. Maybe he discovers some dark secrets about his family or the gods that are connected to this devilish realm.
Well, it depends on the specific fanfiction. There are countless fan - created stories out there, and some might indeed choose to portray Percy Jackson as a devil for the sake of a unique or edgy plot. However, in the mainstream Percy Jackson lore, he has no such association. So while it could be a thing in certain fanfictions, it's not a common or canonical representation.
No, Percy Jackson is a hero in the original series. However, in fanfiction, different writers can have their own interpretations. But it's quite a stretch to make him the devil. Fanfiction sometimes just likes to play with extreme ideas to create shock value or new plotlines that deviate from the source material.
One interesting plotline could be Percy's struggle with his new identity as the 'Son of the Devil'. He might have to face internal conflicts about his nature. For example, he could be torn between his heroic instincts and the dark powers he may inherit.
One idea could be Percy using his devilish powers to protect his friends in a unique way. Maybe he has the power to manipulate shadows and uses this to create illusions to mislead enemies.
Some fanfiction writers may do it to stand out. Since the Percy Jackson series is so well - known, creating a version where he is a devil can attract attention. Also, it could be a way to explore darker themes. The original series has a lot of heroic and positive elements, but in fanfiction, making Percy a devil allows for a look at the other side of the coin, like how his powers could be used for evil instead of good.
Obviously, Percy Jackson himself is usually a main character. He is the one who gets involved in the devil - related situations. And then there could be new characters created specifically for the fanfiction, like a devil - like antagonist who is trying to corrupt Percy or the world around him.
One plot idea could be Percy having to team up with Hera to rescue a group of demigods who have been captured by an ancient monster. Hera, despite her usual aloofness, realizes she needs Percy's unique skills.
A plot could involve Percy being sent to Forks on a quest. He discovers that there's a powerful artifact hidden in the area that could cause chaos if it falls into the wrong hands. The vampires and werewolves in Forks are also after this artifact for their own reasons. Percy has to navigate the complex relationships between these two groups while also trying to keep his true identity as a demigod a secret. Along the way, he forms an unlikely friendship with Jacob, who helps him understand the ways of the werewolves.
One possible plot could be Percy arriving in the DxD world and being mistaken for a new, extremely powerful devil. He then has to navigate the complex politics of the devils while also trying to find a way back home. Along the way, he uses his demigod powers in unique ways against the various threats in the DxD universe.
Maybe in the fanfiction, the zoo is a place where the gods have hidden some of their lost magical artifacts. Percy, being the son of Poseidon, senses a strange water - based magic near the aquarium section. He starts to investigate with Annabeth. Along the way, they face challenges from zoo security (who are unknowingly being influenced by a minor god who doesn't want the artifacts found) and various magical traps set around the exhibits.
