He might be more laid - back. Since Dean has a more easy - going personality compared to some other characters in the Potter universe, Harry could inherit that. He may not be as brooding as the original Harry.
His character becomes more independent. As the son of Artemis, he has a different kind of power and heritage that sets him apart from other wizards. This could lead to him relying less on the help of others and more on his own instincts and abilities. He might also be more secretive about his new powers, which adds a new layer of mystery to his character. For example, he could start to disappear at night to train in the moonlight without telling his friends.
Harry would probably become more physically bold. Since Hercules was known for his strength and heroic deeds, Harry could be more likely to take on challenges head - on, using his physical abilities more often. His personality might also change in terms of his leadership. With the added boost of being related to a great hero, he could be more assertive in leading his friends and the Order of the Phoenix. He'd no longer be just the Boy Who Lived, but also the son of a powerful demigod, which would surely impact how he views himself and his role in the wizarding world.
He might change in terms of his magical abilities. Maybe the Malfoy family focuses on different types of magic than what Harry was exposed to in the original story. So, he could be more proficient in dark arts - adjacent magic, but also struggle with the moral implications of using such magic. He may have to reevaluate his own identity and what it means to be a 'good' wizard.
He could develop new interests and skills. Since he's in a different family environment, he might be exposed to different hobbies or magical studies. For instance, if Dean's family has a tradition of potion - making in a unique way, Harry could pick up on that and become quite proficient, which would also boost his confidence.
He becomes more conflicted. Growing up as Lucius Malfoy's son, he is exposed to different values. So, instead of the Gryffindor - like straightforwardness, he may have a more calculating side.
He'd probably be more morally ambiguous. Growing up as Crowley's son, he might not have the same clear - cut sense of right and wrong as the original Harry. He could be more cunning and less hesitant to use underhanded tactics if necessary.
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 'Harry Potter son of Loki' fanfiction, Harry changes significantly. His sense of identity is greatly shaken. He no longer just sees himself as a simple wizard. He now has this connection to Norse mythology. This makes him more curious about different forms of magic and otherworldly things. He may become more of an outcast as well, since his heritage is so different. But this also makes him stronger in some ways. 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.
Well, in some 'Harry is Dean's son fanfiction', a cool plotline could be his discovery of magic. Since Dean is a half - blood wizard, Harry might have a different experience learning about magic at home. He could be more exposed to the wizarding world's cultural aspects earlier. Also, his friendships might form in a unique way. For example, he could be closer to the Gryffindor students from the start because of his father's house.
If Harry were the son of Hela, his character would undergo a significant transformation. His entire understanding of magic and his place in the wizarding world would be shaken. He'd no longer be just the Boy Who Lived, but the son of a powerful and feared Norse goddess. This new identity would bring out a more assertive side of him. He'd be more willing to question the established rules and authorities in the wizarding world. His personality would become a blend of his original Gryffindor courage and Hela's more unyielding and powerful nature. He might also develop a new set of skills related to Hela's powers, which would change how he approaches challenges and threats in the wizarding world.
