There could be a powerful wizard from a far - off land. This wizard has knowledge of ancient magic that could help or hinder the Son of Neptune. Also, a group of dwarven - like creatures who are excellent craftsmen. They could create special weapons or tools for the Son of Neptune's journey. Additionally, an exiled god who sees the Son of Neptune as a means to regain his former glory.
Including other demigods from different camps can bring in new dynamics. A demigod from the Athena cabin, for instance, could offer their wisdom and strategic thinking. Or a child of Ares who might be more impulsive and aggressive, creating tension within the group. This mix of different personalities and powers can make for a very engaging fanfiction.
In Percy son of Neptune fanfiction, including Nico di Angelo would be interesting. His connection to the underworld could bring a new dimension to the story, especially when dealing with any threats or mysteries that involve both the sea and the underworld. Reyna could also be a great addition. Her leadership skills and combat abilities would make her a valuable ally or a formidable opponent, depending on the plot. And of course, Chiron, the centaur, who could offer his wisdom and guidance to Percy from afar, as he has so much knowledge about the demigod world.
Well, of course, you have to include Percy Jackson himself. Then, there could be a son of Dionysus, like Pollux. He could be a fun character to include as he already has his own experiences and relationships within the Camp Half - Blood. Chiron, the centaur mentor, would also be a great addition. He could offer wisdom and guidance to Percy and the son of Dionysus during their adventures. Another character could be Annabeth Chase. Her strategic mind could come in handy when they are facing difficult situations in the fanfiction.
One potential new character could be a selkie. Selkies are mythological creatures that can transform between seal and human form. This selkie could be an ally or a foe to Percy. Maybe there's a sea nymph who has a special connection to Percy's mother. She could show up to help Percy when he's in a tight spot. And what about a sea giant who was once an enemy of Neptune but now wants to make amends? He could be a very interesting addition to the story.
A wise old mentor figure could be interesting. This character could be human and have a lot of knowledge about the world that they can pass on to the non - human protagonist. For example, a retired professor who has studied anthropology and can help the non - human understand human cultures.
A group of thieves could also be included. They might initially try to steal from the Prince of Darkness but end up getting caught in his web of power and secrets. Their street - smart skills and lack of scruples could create some interesting dynamics as they interact with the Prince and other more noble characters.
A powerful Raikage - like character as an OC would be great. This character could be extremely strong in physical combat and have a no - nonsense attitude towards protecting Kumogakure.
The nosy neighbor can be an interesting addition. They might have their own opinions on whether the couple should love their home or list it. Maybe they're jealous and want the couple to move, or they could be overly attached to the neighborhood and try to convince them to stay.
Well, if it's a crossover with Ultraman, Ultraman could be a great addition. His super strength and light - based powers would contrast well with the Jetman's abilities. They could have a friendly rivalry at first but then team up to face a powerful kaiju that is threatening both their worlds.
Definitely Obito. Since they have a long - standing connection, it would be interesting to see how their relationship played out during Kakashi's Anbu days. Maybe Obito was still alive and had his own secret missions within the Anbu that intersected with Kakashi's.
