There might be a character who is a rival to Harry. This rival could have different motives, like jealousy or a thirst for power. They constantly challenge Harry, which makes for an interesting dynamic. Also, there could be a magical creature character that befriends Harry. For example, a phoenix that can provide help and support in difficult situations, and its own personality and abilities add an interesting aspect to the story.
Well, a common theme is self - discovery. Harry P Acheron Ash could be on a journey to find out more about his true self, his powers, and his place in the world. Another might be mystery. There could be mysterious events or secrets that he has to uncover. For example, secrets about his family or the origin of certain magical elements in the story. And of course, there could be a theme of good vs. evil, where Harry has to fight against some form of dark force or antagonist to protect his world or the people he cares about.
Well, aside from Harry Potter and Acheron, other characters from the original 'Harry Potter' series often play important roles too. Hermione and Ron might be there to support Harry in his new adventures with Acheron. Dumbledore could also make appearances, perhaps guiding Harry and Acheron in their journey, especially if they are dealing with something that has to do with the greater good of the wizarding world.
Pikachu is always an interesting character in these fanfictions. In some stories, Pikachu might develop new abilities or have a deeper understanding of the Pokemon world that it can share with Ash. Another character could be Gary. He can be portrayed as a more complex rival, perhaps with his own hidden motives or a change of heart towards Ash. And then there's Misty. She can have new storylines in fanfictions, like being a powerful water - type Pokemon trainer with her own unique training methods that Ash can learn from.
Hermione would be really interesting. She could help Tsuna with his studies, whether it's about the magical lore of the Harry Potter world or just general knowledge. She might be a bit strict with Tsuna at first, but as time goes on, they could become good friends. Another interesting character would be Dumbledore. He could offer his wisdom and guidance to Harry in raising Tsuna, and might also see some special qualities in Tsuna that could be important for the future of the wizarding world.
Lillie is really interesting. She starts off as a shy girl but grows a lot in her confidence when it comes to Pokemon. Her relationship with her family and their connection to the Aether Foundation adds depth to her character. Then there's Kiawe, who is very proud of his Alola heritage and his strong fire - type Pokemon. His no - nonsense attitude and his eagerness to prove himself make him stand out. And Sophocles, the tech - savvy kid, is always coming up with cool gadgets to help in Pokemon battles or exploration, which is super fun.
One interesting character could be an alternate version of Misty from another dimension. Maybe she's a powerful water - type Pokemon trainer who has mastered techniques that the original Misty hasn't. Another could be a dimension - hopping researcher who is trying to study the different dimensions and their Pokemon. He could be a source of knowledge for Ash, guiding him through the mysteries of the new dimensions. There could also be a villainous character who is causing chaos across the dimensions by stealing rare Pokemon or disrupting the balance between different dimensions.
Hermione would be really interesting. Her thirst for knowledge would make her eager to learn from Bilbo's tales and experiences. She could also help Bilbo understand the complex magic of the wizarding world. Another great character would be Gandalf. If he somehow made his way into the wizarding world, he could offer his wisdom and guidance. And of course, Ron. His loyalty and sense of humor could provide some great comedic moments and also a strong friendship with Bilbo.
Fred and George Weasley are also favorites. Their mischievous nature can be amplified in fanfictions. They could create new and even more spectacular magical pranks specifically aimed at Umbridge, like turning her office into a never - ending maze of trick stairs and hidden rooms filled with various magical creatures that drive her crazy.
Hermione Granger is very influential. She is extremely intelligent and well - read. She often helps Harry and Ron with her vast knowledge of magic, and her determination and loyalty contribute a great deal to their adventures and the fight against evil.
There could be the mafia boss. He might be a tough and shrewd character who takes Harry under his wing at first but later becomes suspicious of Harry's actions. Another main character could be Harry's best friend in the mafia. They go through all the dangerous and exciting adventures together, and this friend might have different views on the mafia life compared to Harry.
