To develop Harry in relation to Acheron, show how he adapts to Acheron's presence. He might start to question his own morality and power when compared to Acheron. Acheron can be developed by showing his reaction to the relatively 'innocent' world of Harry. He could start to soften his hard edges as he spends more time with Harry and experiences the warmth and hope in the wizarding world. This could be a long - term process, with setbacks along the way, but ultimately leading to a more complex and rounded character for both of them.
For Harry, you can focus on his growth beyond what we see in the original series. Maybe he becomes more cynical after all he's been through, and Acheron challenges his views. For Acheron, explore his past more deeply in the context of the fanfiction. Have Harry learn about his traumas and help him heal in some way.
In fanfiction, Harry can develop by learning new magic from Acheron or being exposed to different cultures and powers. Acheron, on the other hand, can develop his relationship with Harry by starting to care about the wizarding world and its inhabitants. This could lead to him becoming more empathetic and less isolated. For example, Harry could introduce Acheron to his friends at Hogwarts, and Acheron could learn about friendship and loyalty from them.
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.
For Harry, you can explore his growth in a non - magical world. He might initially struggle without his wand and the familiar magical environment. But as he teams up with Batgirl, he could learn to adapt and use his wits and basic magical knowledge in new ways. For example, he could use his knowledge of potions to create makeshift antidotes for toxins in Gotham. Batgirl, on the other hand, could learn about the existence of magic from Harry, which could expand her view of the world. This new knowledge could make her more open - minded when facing unusual threats in the future.
For Harry, you could focus on his sense of justice. Maybe he's initially wary of the vampire but his experiences with Voldemort have taught him not to judge too quickly. Fleur can be developed by highlighting her Veela allure and how it affects the vampire. The vampire could be developed by giving him a tragic backstory. For example, he was turned against his will and is trying to find a way to reverse it. This could create an interesting dynamic between the three characters.
For Harry, you could show his struggle to accept Pansy at first. Maybe he has to overcome his preconceived notions of her from their Hogwarts days. As the story progresses, he could start to see her in a new light and become more open - minded.
For Harry Potter, in a fanfiction with Sylvanas, his character could be developed by showing his reaction to Sylvanas' more morally gray actions. He might start to question his own black - and - white view of good and evil. For example, when Sylvanas uses dark magic for what she believes is a greater good, Harry could be forced to think about the nature of magic and its use.
For fem Harry, her character can be developed by showing her struggle with her new identity in a world with Poseidon. She could start as a bit of a loner, but as she bonds with Poseidon, she becomes more confident. Poseidon, on the other hand, can be developed by showing his softer side. Maybe he starts as a very strict god, but as he gets to know fem Harry, he becomes more lenient and caring.
Well, clearly Harry Potter and Acheron are main characters. Harry is the boy wizard we all know from the original series, and Acheron brings in his own set of characteristics and powers from his own lore. Hermione and Ron could also be important characters as they are Harry's closest friends and often get involved in his adventures in fanfictions too.
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.
For Harry, his growth could be shown through how he becomes more open - minded. He starts to embrace Luna's quirks and her different way of seeing things, which in turn makes him more accepting in general. For example, he might initially be a bit hesitant about Luna's belief in some of the more out - there magical creatures, but as they date, he starts to see the beauty in her imagination.
For Harry Potter, you could explore his reaction to the new and very different power that Kylo Ren represents. Maybe he becomes a bit envious of the raw power of the Force at first. As for Kylo Ren, he could be developed by showing his confusion in a world full of magic wands and spells instead of his usual high - tech environment. He might start to question his own dark side tendencies when he sees the way the wizards in the Potter world use magic for good and bad.
