In a fanfic where Harry Potter is controlled by Voldemort, how would the other characters react?

Hermione would be extremely shocked and disappointed. She has always been a firm believer in the fight against Voldemort and would see Harry's alliance as a huge betrayal. She would probably try to talk Harry out of it at first and if that fails, she might start her own investigation to find out what made Harry do this.

Voldemort would be calculating. He might be using the Armistice as a way to regain his strength or plot a new strategy. His Death Eaters would be divided. Some might be happy to have a break from the fighting, while others would be eager to continue the war. Dumbledore's followers would be watching closely too. They would be the ones to keep the balance and make sure that the Armistice doesn't turn into a way for Voldemort to take over completely. The Ministry of Magic would be in a difficult position, trying to enforce the Armistice while also dealing with the different factions within the wizarding world.

Ron would be extremely angry at first. He might feel betrayed by Harry. But as he realizes that something must be seriously wrong with Harry, he would probably join Hermione in trying to save Harry from Voldemort's influence. They would look for a way to break whatever spell or false belief has hold of Harry.

Well, Ginny would be heartbroken that Harry left. She might have expected to build a life with him after Voldemort was defeated. But she's also a strong character, so she would likely throw herself into her own life, perhaps becoming a star Quidditch player. Neville would be overjoyed that Voldemort was dead. He might take on a role at Hogwarts, teaching herbology perhaps, and sharing his knowledge with the students. As for the other characters in the wizarding world, those who had suffered under Voldemort would be in a state of jubilation and start to pick up the pieces of their lives.

Hermione would be devastated. She would initially think Harry had lost his mind. She'd probably try to find a way to rescue him, using all her knowledge and research skills. Ron would be angry at first, feeling that Harry had betrayed them. But then he would also start to think there must be a deeper reason and would want to help. Dumbledore, if still alive in the fanfiction, would likely be more understanding, believing that Harry has a grand plan that he's not aware of yet.

The teachers at Hogwarts would have diverse reactions. McGonagall might be disappointed but would still hope that Harry could resist the dark influence. Snape would be extremely complex in his reaction. Given his history with both Harry and Voldemort, he might see it as a sign of the prophecy coming full circle. The Death Eaters, on the other hand, would see Harry as a potential new leader. They might try to persuade him to embrace the dark side. As for Harry's other friends like Neville, he would be worried but would also stand by Harry, believing that he could make the right choice. The reactions of these characters would create a lot of drama and tension in the fanfic.

The Weasley family would have a range of reactions. Mrs. Weasley would probably be very maternal towards Harry, seeing Lily in his face. Ginny might be a bit shy around Harry at first, seeing him in a new light. Fred and George would likely use it for some good - natured teasing, like creating potions that make Harry's hair grow really long to enhance the resemblance. And Snape, well, seeing Harry look like Lily would be a constant reminder of his unrequited love. He might be even more conflicted in his feelings towards Harry, part of him hating Harry for being James' son but also being drawn to him because of his likeness to Lily.

Hermione would be very worried. She would likely try to convince Harry to come back, reasoning with him about the importance of family. Ron, on the other hand, might be a bit more understanding. He might give Harry some space at first but also keep an eye on him. Dumbledore, if he were still alive, would probably have a long - term view. He might let Harry go for a while, knowing that Harry needs to grow on his own, but also be ready to guide him back when the time is right.

Hermione would probably be both amused and concerned. She might try to find a magical solution to get him out of this situation as quickly as possible while also having a bit of a chuckle at the absurdity of it all.

Hermione would be horrified. She would immediately start trying to figure out a way to rescue Harry. She might start researching in the library for some ancient spells or forgotten magic that could help. Ron would be angry at Dumbledore and would probably want to rush off to save Harry without much of a plan at first.
