The fanfiction could also focus on Naruto's relationships. His friends might be initially shocked or confused about his connection to Arachne. But as the story progresses, they come to accept him for who he is. And perhaps there are new characters introduced who are related to Arachne's world, and Naruto has to navigate his relationships with them while still being part of the ninja community.
Obviously Naruto would be one of the main characters. And since it's about him being the son of Arachne, Arachne herself could be a significant character, either in flashbacks or as some kind of guiding force in Naruto's life. His friends like Sasuke and Sakura would also likely be main characters as they interact with Naruto and are affected by his newfound identity.
In 'Peter Parker son of Arachne fanfiction', a frequently seen theme is the clash between the mortal and the mythological worlds. Since Peter is now connected to the myth of Arachne, he has to navigate how these two worlds interact. There's also the theme of acceptance. He has to accept his new identity and how others will accept him too. And of course, the theme of responsibility. With new powers or a new identity comes new responsibilities, just like in the original Spider - Man concept.
In such a fanfiction, Naruto might develop unique abilities related to Arachne's skills. Maybe he'd be really good at web - based ninjutsu. His personality could also be different, perhaps more cunning like Arachne.
One popular 'Peter Parker son of Arachne fanfiction' is 'The Arachne Legacy'. It delves into how Peter discovers his unique heritage as the son of Arachne and how it changes his relationship with his powers and the people around him. Another great one could be 'Arachne's Son: A New Web'. This fanfic focuses on Peter's struggle to come to terms with his new identity while still trying to be the friendly neighborhood Spider - Man we all know.
A really cool plot could be that the children of Arachne are being wrongly accused of a series of crimes in the demigod world. Percy, being the son of Arachne in this fanfiction, decides to prove their innocence. He has to go through various challenges, like facing false witnesses, dealing with prejudice from other demigods, and uncovering the real culprit who is trying to frame the Arachne descendants.
One possible plot could be Percy, as the son of Arachne, struggling to fit in among the other demigods. He might have unique powers related to weaving and spiders, like being able to create illusions with spiderwebs. He could be initially feared or shunned because of his mother's reputation, but then prove himself a hero by using his powers in creative ways to defeat monsters.
Naruto's character would become more in tune with Arachne's characteristics. He could be more patient and calculating. Since Arachne is often associated with webs and traps, Naruto might be more strategic in his battles and less impulsive. He may also have a different sense of loyalty, not being as blindly loyal to a village as he was in the original story.
First, start with Percy being in denial about his new identity as the son of Arachne. Then gradually have him accept it as he discovers the good aspects of this heritage. For example, the power and loyalty of the Arachne - related demigods.
Annabeth could be a main character. She might be initially distrustful of Percy because of his mother but then come to see his true worth. Another could be Grover, Percy's loyal friend, who stands by him through all the difficulties. There could also be new characters, like a half - spider half - human hybrid who is Percy's distant relative and helps him understand his heritage.
