There's also 'Kane Chronicles Meets the Avengers'. It's a really creative crossover that imagines what would happen if the Kane siblings got involved with the Avengers. It has a lot of action - packed scenes and some really interesting character dynamics.
I really like 'Kane Chronicles and Magnus Chase: A Crossover'. This fanfic is amazing as it brings together two Rick Riordan universes. It delves deep into how the different mythologies can co - exist and interact. The author does a wonderful job of creating new adventures for the characters from both series.
One of the great ones is 'The New Adventures in the Kane Chronicles'. It takes the characters on new and exciting quests that feel like they could be part of the original series. Another good one is 'Kane Chronicles: Alternate Endings' which explores different ways the story could have ended. And 'The Kane Chronicles: Extended Tales' gives more backstory to the characters.
First, know both universes well. For example, understand the magic system in the Kane Chronicles and the character traits of its main characters. Then, create a believable reason for the crossover. Maybe a magical portal opens between the two worlds. Also, keep the voices of the characters true to their original portrayals.
Well, there's a fanfic called 'Crossing Realms'. In this one, the Egyptian magic system from the Kane Chronicles and the Greek mythology elements of Percy Jackson collide. It has some really cool fight scenes where the powers of both universes are pitted against each other. The author does a great job of making the two different mythologies work together in the story.
You can start by checking out FanFiction.net. There are a lot of great stories there. Some focus on the relationships between the characters, like Carter and Sadie's sibling bond. Others might explore different magical adventures they could have had that weren't in the original books.
One great 'Percy Jackson Kane Chronicles' fanfiction is 'The Crossover Quest'. It combines the two universes really well, with exciting plot twists. The characters from both series interact in a very believable way.
It's important to keep an open mind while reading. Fanfiction can vary greatly in terms of writing style, plot, and characterization. Some might deviate a lot from the original source material, but that's part of the fun. You might discover new interpretations of the Kane Chronicles universe that you never thought of before. Also, make sure to respect the authors' work and leave feedback if you can, as it helps them improve and encourages more fanfiction creation.
Anubis would be a great character to include. His complex relationship with Sadie in the original series could be further explored in a crossover. He could bring his knowledge of the underworld and death magic to the story. Also, if it's a crossover with a different mythology, say Greek mythology, Hermes could be included. Hermes' speed and trickery could contrast well with the more structured magic of the Kanes, and there could be some interesting interactions between them.
A cool plot could involve a crossover with a modern - day superhero universe. The Kanes use their magic to help the superheroes defeat a villain who has somehow harnessed ancient Egyptian magic. They could teach the superheroes about the different aspects of Egyptian magic and how it can be used against the villain. For example, using the power of Ra to counter the villain's dark spells.
Maybe there's a magical artifact that has significance in both Egyptian and Greek mythology. The characters like Percy and Carter Kane have to team up. Percy could use his water powers and Carter his magic to navigate through various challenges. They might start off distrusting each other because of their different mythological backgrounds but then realize they need to work together to stop the artifact from falling into the wrong hands.
One idea could be that Kane discovers a portal to the Naruto universe and has to learn ninjutsu to survive. He could team up with Naruto and his friends to fight a common enemy like Orochimaru who is interested in Kane's unique powers from his own world.
