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.
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.
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.
It would change the power dynamics. Magic has been the main form of combat and defense in the Harry Potter world. Guns would introduce a more Muggle - like, instant form of attack. For example, in a duel, instead of casting spells, a wizard could quickly draw a gun. This would make battles more unpredictable and change the strategies used by characters like Harry.
The plot would become very dark. Harry would no longer be the hero, so the fight against Voldemort would likely take a different turn. Maybe Voldemort would see Harry as an ally instead of an enemy. The other characters would have to either try to change Harry back or find a new way to defeat Voldemort without Harry's help.
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.
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.
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.
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.
