Apollo could be a likely candidate. Apollo is associated with beauty, intelligence, and archery. Draco is often described as having a certain grace and he is also quite intelligent in his own way. His ability to aim spells accurately could be seen as an echo of Apollo's archery skills.
Well, his wizarding abilities like spell - casting could be enhanced by his demigod powers. For example, if he has the strength of a certain Greek god, it might make his hexes more powerful. His demigod speed could also help him dodge spells more easily in a wizarding duel.
He might have the power of persuasion if he was related to a god like Mercury. Since he was quite good at manipulating situations in the Harry Potter series, this power would fit him well.
Maybe he has the power of elemental control. Given his Slytherin nature, water or air control would be fitting. He could use water to create barriers or air to send messages or eavesdrop on conversations. This would add a new dimension to his sneaky and resourceful character.
Well, Draco could be a son of a Roman god like Mercury. His slytherin traits of cunning and ambition could be seen as gifts from the god. Maybe his family's pure - blood mania in the HP world could be translated into a sense of superiority due to his divine heritage in the demigod world.
If Draco Malfoy is a demigod in fanfiction, his character traits would change significantly. His loyalty, which was somewhat wavering in the original series, could become more steadfast. Maybe his demigod nature makes him feel a stronger connection to a certain group or cause. Also, his arrogance could be dialed up to eleven as he might believe he has the right to rule or lead because of his divine blood.
One possibility could be Hephaestus. Given Tony's talent for building and creating advanced technology, it would make sense for Hephaestus, the god of blacksmiths and craftsmen, to be his father.
Yes, in some fanfiction concepts, Draco could be a secret demigod. Fanfiction often takes creative liberties with existing characters, and making Draco a demigod can add an exciting new dimension to his character. It might involve him having special powers or a connection to a divine being that was previously unknown, which could lead to all sorts of interesting plot developments within the fan - made story.
Another theme is redemption. In the original story, Draco may have made some not - so - great choices. In these fanfictions, his journey as a demigod can be seen as a way to redeem himself. He can use his new powers and status to make up for his past mistakes and become a better version of himself. This theme gives the character more depth and makes the story more interesting for the readers.
In Draco Malfoy family fanfiction, the relationship between Draco and his mother, Narcissa, can be really fascinating. Some stories might show Narcissa as a more protective and loving mother than we saw in the original books. For example, she could be secretly helping Draco make better choices away from the Dark Arts, which would change the whole family's path.
