He could develop a more cunning side. Bellatrix is a sly character, and Harry would need to learn to be crafty to survive in her world. This would be a big change from his usually straightforward and brave self. For example, he might learn how to deceive Death Eaters or other threats.
His relationship with magic could change significantly. Instead of the traditional Hogwarts - taught magic, he could be delving into darker or more ancient forms of magic under Bellatrix's influence. This would not only affect his magical abilities but also his understanding of the wizarding world and his place in it. He might even start to see magic as a tool for more than just good deeds, which would be a huge shift in his character.
Harry might become more conflicted. He'd be exposed to Grindelwald's ideas which could make him question the black - and - white view of good and evil he had before. His confidence could waver as he's no longer in the familiar Hogwarts environment.
His character would be under great pressure. He might become more secretive and cunning as he tries to hide his true feelings. Since Bellatrix is so unpredictable, Harry would need to be on guard all the time, which could make him more paranoid than the normal Harry we know.
Harry becomes more confident. With Dumbledore as his adoptive father, he has a stronger support system. He is no longer as alone as he was, and this newfound security allows him to take more risks in his magical studies and in fighting dark forces. His sense of identity also shifts. He starts to see himself as part of Dumbledore's legacy, which gives him a greater sense of purpose.
He'd be more confident. With Sally's love and support, he wouldn't have the self - doubt that he had in the original story. He'd be quicker to trust people and might be more open - minded about different forms of magic.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
Snape's character development in this fanfiction would be quite complex. At first, he might be very hesitant and unsure of how to be a father. But as he spends time with Harry, he'd gradually let down his guard. He'd find himself enjoying the simple joys of seeing Harry learn and grow. His relationship with the other Hogwarts staff might also change. He could become more collaborative as he realizes he needs support in raising Harry. His loyalty would still be there, but it would expand to include his newfound family with Harry. This would completely transform his character from the bitter and vengeful man he was in the original story into a more well - rounded and loving person.
At first, their relationship would be full of distrust. Harry would be wary of Bellatrix as she has been an enemy for so long. But as the training progresses, he might start to see a different side of her. Bellatrix, on the other hand, might develop a strange sense of pride in Harry's progress.
Their relationship could develop in a very interesting way. At first, Aragorn might be a bit wary of Harry's magic, but as he sees Harry use it for good, he would start to trust him more. Harry, on the other hand, would look up to Aragorn as a strong and noble father figure. They would bond over shared experiences like facing danger together. For example, when they are attacked by orcs, they would rely on each other's skills - Aragorn's combat skills and Harry's magic - to survive, which would deepen their bond.
His character development could be a long and complex process. At first, he might be obedient to Bellatrix due to her being his caregiver. But as he discovers more about his demigod side, he could start to question her teachings. He might become more independent and start to form his own moral code. For example, he could learn about the demigod concept of balance and try to apply it to the wizarding world, which is often filled with black - and - white views of good and evil. This would lead to him having a more nuanced view of the world around him.
Percy would likely become more empathetic. Harry's difficult past could open Percy's eyes to the hardships others face. He'd probably become less rigid about rules as he realizes Harry needs more than just strictures.
