It could also make him more responsible. Potter Manor is his family's legacy, so he would feel the need to take care of it. This could translate to him being more responsible in other aspects of his life, like his studies at Hogwarts and his relationships with his friends. He would have to manage the manor's magical protections and secrets, which would require maturity. For example, he might have to learn complex spells to safeguard the manor from dark wizards, and this would force him to study harder. In addition, he could use the manor as a place to host his friends during holidays, which would improve his hosting and social skills. He would learn to be more accommodating and make sure everyone is having a good time, just like a proper host should. All these experiences in the manor would gradually shape him into a more well - rounded and responsible person.
The Potter Manor could make Harry more confident. Living in a grand and important family home might give him a stronger sense of identity. He would know that he comes from a long line of great wizards, and this could boost his self - assurance in his magical abilities.
Living in Egypt could make Harry more culturally aware. He would be immersed in a different magical culture, with different values and traditions. This might make him more open - minded and empathetic towards different ways of doing magic. He would also likely be more attuned to the spiritual side of magic, as Egyptian magic often has strong ties to their religious and spiritual beliefs. For example, he might view magic as more of a connection to the gods or the afterlife, rather than just a tool like in the British wizarding world. This could change his overall attitude towards magic and his place in the wizarding world.
He might become more in tune with nature. Since the Phoenix is a symbol of rebirth and nature in the wizarding world, Harry could develop a stronger sense of environmental magic. For example, he could be able to communicate with other magical creatures more easily, not just the Phoenix.
He becomes more humble. Elves are used to serving and being in a subservient position. Growing up with them, Harry would learn the value of every being, no matter their status. He'd be less likely to show off his magical abilities like he might have in the original story.
He becomes more brooding. The knowledge of necromancy and the power it brings can isolate him as he realizes it's a power not many understand or accept. So he might withdraw from his usual jovial self.
He might become more sneaky and calculating. Since he's a thief now, he would have to be good at hiding his actions and planning his 'heists'. His moral compass might also shift a bit as stealing isn't exactly an ethical behavior in the normal wizarding world.

He has to rely on himself more and develop his own unique set of skills and powers that come from both his Potter and Loki lineage.
Harry in this fanfiction is likely to be more ruthless. Voldemort's upbringing would make him less empathetic. He may value power above all else and be more willing to use dark magic to achieve his goals. His relationships would also be different. He wouldn't have the same close - knit group of friends as in the original story. Instead, he might be surrounded by Death Eaters or those who follow Voldemort's ideology.
In this fanfiction, Harry's change is quite significant. Firstly, his view of himself and his place in the world is completely altered. Instead of just being a wizard, he is now part of something much bigger. This new identity gives him a different kind of courage. He's not just fighting for the wizarding world against Voldemort, but also has a connection to Asgard. His relationships with his friends also change. They might see him in a new light, and he might have to deal with their different reactions. He could become more of a leader, using his new powers and status to inspire others. And his magic might even be influenced by his Asgardian heritage, making it more powerful or having different manifestations.
In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.
She can become more sympathetic. Sometimes in fanfiction, authors might give her a tragic past that makes her actions more understandable. For example, if she was wronged by the wizarding community in the past, it could justify her actions against them in the fanfiction.
