One possible plot could be that Harry grows up with a different perspective on the wizarding world. Narcissa might shield him from the more extreme pure - blood ideologies in her own family. He could still have his natural talent for magic but be trained in a more Slytherin - like way, focusing on cunning and self - preservation. And he might have a different relationship with Draco, perhaps more of a brotherly bond.
In such a fanfiction scenario, Harry might be exposed to a very different upbringing. Lucius could try to indoctrinate Harry with pure - blood supremacist ideas at first. But as time goes on, Harry's strong sense of justice might conflict with Lucius's beliefs. Maybe Harry would gradually change Lucius's view on Muggle - borns, or he could use his influence within the Malfoy family to bring about some positive changes in the wizarding world's view on blood purity.
One possible plot twist could be that Malfoy's family initially objects to the adoption but then slowly comes to accept Harry. For example, Lucius Malfoy might see potential benefits in having Harry Potter, the famous wizard, in their family. Another twist could be that Harry, while growing up with the Malfoys, starts to influence them to be less prejudiced. He might introduce them to his friends from Hogwarts like Ron and Hermione, which would be a huge culture shock for the Malfoy family.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
His personality might become more reserved. Growing up in the Malfoy household, he'd be surrounded by Slytherin values. So he could be more calculating and less impulsive compared to his original self. But he would still have that core of kindness from his parents.
His life would change drastically. He'd be living in a different environment, with different values being pushed on him. Instead of the Dursleys' neglect, he'd face Lucius's attempts to mold him into a pure - blood - ideal wizard.
