Harry's magic development could also be linked to his emotional bond with the giants. Their rough but sincere way of life might make his magic more responsive to his emotions. When he is angry or protective, his magic could flare up in a big way. This is different from the more controlled and often academic approach to magic in the regular wizarding upbringing.
The magic within Harry could be influenced by the raw power of the giants. He may be able to access a deeper well of magic due to his exposure to their strength. His spells could be more powerful but also less refined in the beginning. As he enters the wizarding world, he has to learn to control this power better and mold it into the more accepted forms of magic used in Hogwarts.
His magic might develop in a more instinctive and self - taught way. Without the guidance of Hogwarts professors, Harry would have to figure out his magic on his own. He might use it more for survival and self - defense against the threats that Jason's world presents. For example, he could use magic to create barriers or traps to keep enemies at bay.
Harry's character could develop into a more serene and centered individual. Lady Magic's influence could instill in him a sense of calm and purpose. He would not be as easily rattled by the challenges that come his way. For example, he might face Voldemort with a different kind of confidence, not just the courage that comes from his friends and Hogwarts, but from his own deep - seated connection to the very source of magic. This could also make him more empathetic towards magical beings, as he would understand the magic within them on a deeper level.
His magic would likely be more combat - focused. Esdeath would push Harry to use magic as a weapon in the most effective way possible. So, instead of just learning defensive spells first, he might start with offensive ones. He could also develop his magic in a more physical sense, like using it to enhance his speed or strength during battles, similar to how Esdeath might use her own abilities in combat.
If Hidan raised Harry Potter, Harry's magic development would be very different. Hidan doesn't value the traditional ways of learning. So Harry might learn magic through trial and error in real - life dangerous situations. His spells could be more improvised and less refined in the traditional sense. For example, instead of learning the proper wand movements for a spell in a classroom, he might learn how to quickly cast a spell while being attacked. This could make his magic more instinctive but also less precise in some aspects.
His magic might develop in a more practical and combat - oriented way. Instead of just using magic for spells in a classroom or dueling, he could learn to use it in the heat of battle at sea. For example, he might learn to quickly cast protective spells while on a ship during an enemy attack.
Well, if Harry Potter was raised by Orochimaru, his magic might develop in a rather different way. Orochimaru is all about experimentation and pushing limits. He might encourage Harry to explore the darker aspects of magic earlier. Harry could end up with a more unorthodox style of spell - casting, perhaps mixing some of the dark arts with traditional wizardry. But he would also have to fight against Orochimaru's more immoral teachings to stay true to his own values.
Harry's character would undergo a significant transformation. The Cullens' values of self - sacrifice and protecting the family would influence him. He'd likely become more empathetic towards non - human beings. His magic might be used in more creative ways to adapt to the Cullens' lifestyle. For instance, he could use magic to make their home more vampire - friendly. His confidence would grow as he learns from the Cullens' strong family bond.
He would likely be more confident. Growing up with gods would give him a sense of self - assurance that he lacks in the original story. He might be less hesitant in using his powers.
His character would be more assertive. He'd be used to taking action quickly due to his Warrior upbringing. He might be less hesitant in difficult situations compared to the original Harry.
His character would be more stable. Without the Dursleys' abuse, he would be less angry and more trusting.
