Percy would be really interesting. His skills and experiences are so diverse. He could consider so many different careers like being a hero - which he already kind of is - or he could use his swimming skills for something like marine rescue. He has a great sense of adventure which could lead him to explore different career paths that are both exciting and useful.
Annabeth is also a great choice. She's super smart and her love for architecture and strategy could make for an interesting Career Day story. She could talk about how she wants to rebuild and design better places for demigods to live. Maybe she'd even present ideas on how to make the Camp Half - Blood more efficient and safer. She could inspire the younger demigods to think about using their brains in a practical way for their future careers.
In a 'Percy Jackson Career Day' fanfiction, Percy might consider a career as a sea explorer. Since he has such a strong connection to the ocean, he could use his skills to discover new sea creatures or underwater ruins. He could also teach others about the importance of the ocean.
I think Percy Jackson himself would be really interesting. He has such a strong personality and his powers are unique. In a fanfiction with Descendants, he could bring his demigod skills and his sense of adventure. He might be a bit of a fish out of water in the Descendants' world, which could lead to some really funny and exciting situations. His loyalty and determination would also make him a great character to drive the story forward.
I think Mal from Descendants would be really interesting. If you combine her with the Percy Jackson universe, her skills in magic and her somewhat villainous past could create a lot of drama. She could be a bit of an outcast among the demigods at first because of her heritage, but then prove herself as a valuable ally. For example, she could use her magic to help the demigods in a battle against a new type of monster that is resistant to normal demigod powers.
Annabeth Chase could be an interesting character to focus on. She is highly intelligent and strategic. In a crossover, she could use her knowledge of architecture and battle strategies to help Eragon and his allies. She might study the magic in Alagaesia and find similarities or differences with the powers of the demigods. Her relationship with Percy could also be explored in a new light, especially when they are in a completely different world. How would they support each other in this new and strange environment? And how would she interact with the characters in Eragon's world?
Annabeth Chase would be an exciting character to center on. Her intelligence and strategic thinking would be a great asset in the maze. She could quickly analyze the layout of the maze and come up with plans. She might also be the one to bridge the gap between the two groups, as she's good at understanding different people and situations. Her knowledge of architecture and mazes from her own world could be applied to solving the mysteries of the Maze Runner's maze. And her relationship with Percy would add an extra layer of drama, especially when dealing with the new and dangerous situations in the crossover world.
I think one of the AHS swim team members who is really skeptical at first about Percy's claims of being a demigod could be an interesting focus. As they start to see evidence of the supernatural world, their journey from disbelief to belief and their growth in understanding would be great to explore. They could also develop a strong friendship with Percy along the way.
Percy and Annabeth are always interesting to focus on. Their relationship is central to the story, and in the House of Hades, there are so many opportunities to explore their bond further. They are both strong, yet vulnerable in different ways. Nico di Angelo is also a great character to focus on. His past and his connection to the underworld give him a unique perspective. Plus, his powers are really cool. Another interesting character could be Bob, the Titan. He has a complex personality and his loyalty to Percy and the others adds an interesting dynamic.
Percy and Annabeth are always interesting. Their relationship is central to the series, and in the House of Hades, they face extreme challenges that can be explored further. Their love and loyalty to each other can be put to the test in different ways. For example, when they are separated, how do they each cope and still strive towards their common goal? Another interesting character is Nico. He has a deep connection to the underworld and his own complex backstory. In the House of Hades, his powers and knowledge could be further developed in fanfiction.
Percy himself is always a great focus. You can explore his character more deeply, like his insecurities or his growth. Also, Annabeth is a great choice. Her intelligence and strategic thinking can be developed further in a redo.
Nico di Angelo would be an interesting choice. His dark and brooding nature along with his powers over the dead would be a contrast to the more light - hearted aspects of the Harry Potter world in some ways. He could introduce the wizards to the concept of the Underworld and the spirits. And his ability to shadow - travel could be used in some really creative ways, like getting the group in and out of dangerous situations quickly, whether it's in Hogwarts or in the magical areas related to Greek mythology.
