Who are the potential characters that could be involved in 'evil harry potter crossover fanfiction'?

Naruto himself would be a key character. His relationship with Kakashi is a central part of the original story, so seeing how he reacts to an evil Kakashi would be fascinating. Sasuke could also be involved. He and Kakashi have a complex relationship, and an evil Kakashi might try to manipulate Sasuke further for his own dark purposes.

There could also be new characters introduced. Maybe other magizoologists from different parts of the wizarding world. They could have different approaches and beliefs about magical creatures. Some might be rivals, trying to outdo Harry in the discovery and study of new species, while others could be mentors, guiding him in the complex world of magizoology.

Obviously, Harry Potter himself. Then there could be Hermione and Ron, who would be his friends and help him deal with the revelations of his parentage. Dumbledore would also be there, guiding Harry as he tries to understand his connection to Ariel. And perhaps some sea - based characters like mermaids or sea wizards who come to Hogwarts to interact with Harry.

On the Hogwarts side, Hermione and Ron would surely be there. They could be quite bewildered by Harry's newfound connection to Olympus. And Dumbledore, he might have some knowledge about the connection between the two worlds and could guide Harry in some way. From the Olympus side, Athena could also be involved as she is the goddess of wisdom and might see potential in Harry.

Dumbledore could make an appearance. He might be the one who gives Harry the idea to become a pilot in the first place or provides some ancient magical knowledge about flying that helps Harry in his new career. Also, the Weasley twins could be involved. They could create some magical gadgets for the plane, like a device that makes the plane do cool stunts.

Luna Lovegood would be an interesting addition. Her unique view of the world and her kindness would make her a great part of the harem. Draco Malfoy could also be thrown into the mix in a more reformed state, adding some tension and complexity. And from a crossover aspect, perhaps a mermaid character who has the ability to transform into a human during the wedding and is drawn to Harry's heroism.

Hermione Granger would definitely be a key character. Her intelligence and magical ability would make her an important part of any harem situation around Harry. Then there could be characters like Arwen from 'Lord of the Rings'. Her beauty and elven magic would bring a different dynamic. Also, Sakura from 'Naruto' could be included. Her medical ninjutsu and strong will could add to the mix in the harem.

Another potential character could be Naruto. Naruto has his own set of ninja powers and a strong will. If he were in a crossover with Vegeta, their different ideologies about power and friendship could clash or they could learn from each other. Naruto's ability to never give up might inspire Vegeta in some ways, or Vegeta's raw power could amaze Naruto.

In this fanfiction, characters like Luffy from One Piece might be involved. Luffy's carefree yet determined nature would contrast with Ichigo's new god - like presence. Also, characters from the Bleach universe itself could have new relationships with Ichigo. For instance, Aizen might see Ichigo's godhood as a threat or an opportunity, leading to a complex plot development.

The Weasley twins could be part of it too. Suppose Harry yells in excitement or anger about a new prank idea that the twins have come up with that might be a bit too dangerous. They could either encourage his yelling or try to tone it down, depending on their mood. And Malfoy might overhear Harry's yell and use it as an opportunity to taunt him, adding more conflict to the fanfiction.
