If Harry was the son of Loki, his confidence would likely take a different turn. Instead of the somewhat hesitant confidence he has in the original series, he might have a more brash and calculated confidence. He would be more aware of his potential power and be more willing to take risks. His relationships with his friends would also change. Some might be drawn to his new, more exciting and dangerous side, while others might be put off by the Loki - like traits emerging in him. He would have to learn to manage these new aspects of his character while still maintaining his core identity as Harry Potter.
Loki would likely lose his usual sense of self - determination. He's normally a character who has his own plans and motives, but under Thanos' control, he would be more like a puppet. His actions would be dictated by Thanos rather than his own desires.
Harry would likely have a different set of values. Yugi had a strong sense of justice and friendship in Yu - Gi - Oh. As Yugi's son, Harry would place even more emphasis on these values. He might be more open to different cultures and beings, since the Yu - Gi - Oh world has a wide variety of characters. Also, his appearance might be a bit different, perhaps having some features that are more in line with the Japanese - inspired look of the Yu - Gi - Oh characters.

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.

He could also be more of a loner, as his unique heritage might make it hard for others to fully understand him.
He would be more powerful. Harry would likely have a sense of grandeur and a different view of his place in the world. His confidence might soar as he realizes he has such a powerful lineage.
