Harry's character would develop a sense of divinity within him. Since he's raised by Greek gods, he'd have a different relationship with power. He wouldn't fear power as much as he might in the original story. Instead, he'd see it as a natural part of his being. He'd be more in tune with nature and the elements, like the gods are. His relationships with other characters would also change. He might be more aloof towards some of his Hogwarts friends at first, as he'd have this whole other world of experiences from his upbringing among the gods that they couldn't understand right away.
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.
Harry's character would likely become more confident. Knowing he is the son of Greek gods would give him a sense of greater purpose and power. He might start to question the rules of the wizarding world more, as his new identity makes him part of something bigger. His loyalty to his friends would remain strong, but he might be more independent in his actions, relying on his new demigod powers to solve problems.
He'd likely be more attuned to the darker aspects of magic. Since the Hel Gods are associated with darker realms, Harry might not shy away from what's considered 'dark magic' as much as in the original story. He could be more of an outcast among the regular wizards who fear his different upbringing.
His relationships would be very different. With Hermione and Ron, he might seem like an enigma at first. His wolf - raised nature could make him more aloof or independent. He might not understand some of their social norms right away. But they could also be drawn to his unique qualities. His relationship with teachers would also be strange. They might not know how to handle a student with such an unorthodox upbringing.
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.

His character would be more stable. Without the Dursleys' abuse, he would be less angry and more trusting.
In this kind of fanfiction, Harry would develop a very different set of values. Growing up with pirates, he'd value things like loot, loyalty among the crew, and freedom of the seas. His sense of justice might be more like a pirate's idea of justice - rough and ready. He'd be bolder in his actions and less likely to wait for permission or guidance. For instance, if he saw something wrong at Hogwarts, he'd take matters into his own hands immediately rather than go through proper channels. He'd also have a more salty language perhaps, and his interactions with other students would be interesting as he tries to fit in while still holding onto his pirate - raised ways.
In this fanfiction, Harry's character would develop in a very different direction. He would likely be more of an outcast. Growing up with a Nundu, he wouldn't have the normal social interactions a wizard kid has. So, he could be more withdrawn and less communicative. But at the same time, he would be very self - reliant and have a strong survival instinct.
His character would likely be much more aggressive. Trigon's influence would push Harry to be more assertive and less hesitant. He'd probably have a quicker temper too.
