The plot would take a huge turn. For one, the Order of the Phoenix and Dumbledore's Army would be in chaos as they were relying on Harry to be the one to take on Voldemort. They would have to re - evaluate their entire strategy. Instead of a straightforward battle - oriented plot, it might shift towards a more diplomatic or psychological struggle.
The story might then focus more on the magical community's reaction to Harry's decision. Some might see him as a coward, while others might start to question the long - held belief that only Harry can defeat Voldemort. This could lead to factions forming within the wizarding world, with some trying to persuade Harry to fight and others exploring alternative ways to deal with Voldemort, which would completely reshape the plot from the original story.
One possible reason could be that Harry has grown tired of the cycle of violence. He might have seen how much destruction the fight has already caused and decides that there has to be another way. Maybe he believes that by refusing to fight, he can break the pattern and find a more peaceful solution to end Voldemort's reign of terror.
Well, in such a fanfiction, Harry being Voldemort's snake might initially make their relationship more of a master - servant one. But as the story progresses, Harry could start to resist Voldemort's control, leading to a more adversarial relationship.
His reaction would likely be very different. At first, he might be angry that he didn't know this before. But then, he could start to see opportunities. He may think that if he can somehow control Harry as a Horcrux, he can gain more power. So, he might change his strategy from simply trying to murder Harry to trying to subdue him in a different way.
The story could take a darker turn if he refuses to go back to the Dursleys. Maybe without the protection of the blood magic at the Dursleys' place (even if they were cruel), he becomes more vulnerable to Voldemort's attacks earlier. Or, on the other hand, he could find a new form of protection that was not part of the original story, which could change the power dynamics in the fight against Voldemort.
Well, if Voldemort is weak, the whole threat level in the story drops significantly. Harry and his friends might not have to go through such intense battles and trials. Instead of a long - drawn - out war, it could be more of a quick resolution where they easily overcome Voldemort. The focus of the plot might shift from the fight against Voldemort to other aspects like exploring the wizarding world more, or dealing with other smaller threats that were overshadowed by Voldemort in the original series.
This twist would likely change everything. Harry's entire moral compass could be shaken. The way he views magic and the wizarding world would likely be warped. And it would definitely cause chaos among his friends and allies.
He becomes more conflicted. Knowing he's Voldemort's son, he's constantly in turmoil about his true nature. His confidence might waver as he wonders if he's capable of the same evil as his father.
Well, it might make him more cynical at first. After all, he has just absorbed the essence of the most evil wizard. But then he could use this newfound darkness within him to better understand the bad in the wizarding world and fight it more effectively.
It could be that he has some personal traumas related to fighting. For example, he might have seen the negative consequences of fighting in the past, such as the loss of loved ones or destruction of places he cares about, so he refuses to engage in it. In addition, he may also be influenced by certain moral or ethical beliefs within the context of the fanfic's world, which lead him to oppose fighting.
His refusal might force the story to develop in non - violent ways. New solutions have to be found to resolve the problems without fighting. This could involve things like political intrigue, diplomatic negotiations, or uncovering secrets. For instance, instead of fighting a villain directly, Harry may start to dig into the villain's past to find a way to neutralize them without combat. Also, it can change the power dynamics in the story. If Harry was supposed to be a key fighter, his refusal could make other characters step up or new alliances form to compensate for his lack of fighting.
