An independent powerful lord would have a huge impact on the plot. He could create his own army of followers, which would change the power dynamics. This might force Harry and his friends to consider different strategies. Instead of just focusing on Voldemort, they might have to deal with this new threat as well. Also, this lord could offer different solutions to the problems in the wizarding world. For instance, he might have a better idea about how to deal with the discrimination against Muggle - borns. His influence could lead to different alliances and betrayals among the characters, completely changing the course of the story.
An independent powerful lord in Harry Potter fanfiction is interesting because he represents a wildcard. He doesn't fit into the usual categories of good or bad. His actions are unpredictable. He could be a source of new knowledge and magic, which is always exciting in the wizarding world. He might have his own code of conduct that challenges the norms of the wizarding society.
The plot would change a great deal. For one, Harry would be much more powerful physically. So when facing Voldemort, he could use Thor's strength in combat, not just rely on magic. He might be able to take on Death Eaters more easily.
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.
Harry would probably be more attuned to dark magic. His upbringing by Satan would expose him to different forms of magic and he would have a different understanding of power. He might be more ruthless in achieving his goals and less concerned about the consequences for others. For example, in the original series, Harry was always worried about the safety of his friends, but in this fanfiction, he might use his friends as pawns if it served his purpose.
The plot would change significantly. For one, the final battles against the dark forces would be different. Instead of a wand - only battle at Hogwarts, there could be a full - scale war with modern weapons. The Death Eaters might not be prepared for the firepower of things like machine guns or grenades. It could also change the way characters interact. Hermione might study the mechanics of modern weapons instead of just ancient spells, and Ron could be in charge of weapon supplies.
In this fanfiction concept, the plot would see major alterations. With Flash's influence, Harry might not rely as much on traditional magic for transportation. He could zip around Hogwarts and the wizarding world at high speeds, changing the dynamics of his adventures. His battles against dark wizards would be different too. Instead of long, drawn - out duels, he could quickly close the distance and catch his opponents off - guard. Also, his relationship with Dumbledore might be different as he has this new, unorthodox way of dealing with threats.
The plot could change a great deal. For one, the threat of Voldemort might not be as immediate or known in the same way. Harry could be dealing with different dark forces in America, like some ancient and malevolent American - based dark wizards. His journey to discover his past and his power would likely take different turns as he navigates the American wizarding world.
In fanfiction, a female Voldemort could bring in new sub - plots. For example, she could be related to some of the other female characters in ways that the male Voldemort couldn't be. This could create new storylines about family secrets or female - centric magic. Her presence could also inspire other female characters to either oppose her more vehemently or be drawn to her power, changing the overall power dynamics in the wizarding world.
The plot could change drastically. If Harry is reborn, his entire backstory and origin would be different. This would mean that the events leading up to his fight against Voldemort would be altered. Maybe in this reborn version, Voldemort never became as powerful as he did in the original story because Harry was reborn with some sort of special protection that weakened Voldemort from the start.
Well, a genie could offer Hermione the ability to master all magic spells instantly. This would make her an even more formidable force in the fight against the Dark Arts. It might also lead to her being able to develop new spells or defenses that could turn the tide in the wizarding war much faster. So the plot would shift from a more gradual battle of wits and power to a quicker resolution with Hermione's new - found all - powerful magic.
