Harry would likely be more confident in the Muggle world. Since Tony Dinozzo would expose him to all kinds of Muggle situations from a young age, Harry wouldn't be as shy or out of place among Muggles as he was in the original story. For example, he might be more comfortable using Muggle technology.
They'd probably start off a bit rocky. Harry is used to the wizarding world's ways, and Tony has his own unique style. But eventually, they'd bond. Tony would see Harry's courage and want to protect him. Harry would see Tony as a father figure who could offer different kinds of support than he's had before.
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.
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 So, he could be more withdrawn and less communicative.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.
Harry's character would develop a stronger sense of justice. Supergirl is all about fighting for what's right, and Harry, growing up with her, would internalize that. He might be more proactive in seeking out and combating evil, rather than waiting for it to come to him like he sometimes does in the original story.
His character would become more complex. Harry would have a mix of the kindness and loyalty from his original self, but also Netero's no - nonsense attitude. He could be more calculating in his actions, thinking several steps ahead like Netero might in a battle.
