I think Grover Underwood from Percy's world would be a great addition. His connection to nature and his role as a protector could bring a different perspective. In Carter's world, Walt Stone would be interesting. His situation with his magic and his relationship with Carter could add depth. Also, Chiron from Percy's story could play an important role. He could be the one to initially recognize the need for the crossover and help the two groups come together. Bast from Carter's side could also be included. Her feline - like nature and powerful abilities would be exciting in the context of a crossover.
Obviously, Percy Jackson and Carter Kane themselves are the most essential characters. Their different personalities and powers would create a great dynamic. Percy with his ability to control water and his quick - wittedness, and Carter with his skills in Egyptian magic. Annabeth Chase from Percy's world would also be interesting. Her strategic mind could help in planning against the combined threats. And from Carter's side, Sadie Kane could add a lot. Her sass and powerful magic would make her a force to be reckoned with. Plus, the interactions between Annabeth and Sadie would be really fun to write.
Sadie Kane, Carter's sister, is another character that gets a lot of love in fanfiction. Her sassy personality and powerful magic make her a great addition to any story involving Carter and Percy. She can add some humor and also be a strong ally in battles or other challenges that the characters face in the fan - created stories.
They could be competitive at first. Each thinking their own powers and heritage are superior. But then they'd find common ground in their shared experiences as heroes in their respective mythologies.
Percy and Sadie would be really interesting. Percy with his laid - back yet heroic nature and Sadie with her sassy and powerful magic. They could have some great banter while fighting off monsters.
Definitely Percy Jackson and Carter Kane. Percy has his skills with water and being a demigod, and Carter is a powerful magician. Their different ways of approaching problems and their unique powers would make for an interesting dynamic. Another great pairing could be Annabeth Chase and Sadie Kane. Annabeth is known for her strategic thinking and knowledge of Greek mythology, while Sadie is full of sass and has deep knowledge of Egyptian magic. They could bounce ideas off each other and learn a lot.
It's really hard to say. Percy has his water powers and is a great swordsman. Carter, on the other hand, can use Egyptian magic. In fanfiction, it could go either way depending on how the author wants to write it. Maybe if the battle is near water, Percy has an advantage, but if it's in a place with strong Egyptian magic influence, Carter might win.
Percy and Carter would be likely to form an alliance. Percy is used to leading and being in dangerous situations, and Carter has a similar sense of responsibility. They both have powers related to water in a way (Percy's direct control of water and Carter's connection to the Nile). Their leadership skills would make them work well together to face any common threats in the crossover world.
A great plot twist could be that they end up having to team up instead of fight. Maybe there's a greater evil that combines elements of Greek and Egyptian mythology that they can only defeat together. Their powers could combine in unexpected ways, like Percy's water powers being able to enhance Carter's magic related to the Nile.
He might find it really interesting. Since both Percy Jackson and Carter Kane are from different but equally rich myth - based series, he could gain new perspectives on how to blend modern settings with ancient myths, which is something his own series also does.
One exciting plot could be that the Greek and Egyptian mythologies start to blend in a strange way. Maybe the Mist from Percy's world and the magic in Carter's world get all jumbled up. This causes chaos as monsters from both mythologies start showing up in unexpected places. Percy and Carter have to team up, along with their friends, to figure out what's causing this and how to stop it before the entire world is overrun by a mix of mythological beasts.
Definitely Percy and Carter. Percy is used to his own brand of heroism and power from the Greek world, while Carter has been trained in the ways of Egyptian magic. They could start off being a bit competitive, each thinking their own way is better. But as they face challenges together, they would learn to respect each other's skills. For example, when they are fighting a combined Greek - Egyptian monster, Percy's quick thinking in battle and Carter's knowledge of ancient spells could complement each other.
