The Weasley family, for the most part, would be likely to support Harry. They have a history of standing up against the Dark Arts and unjust situations. Also, Luna Lovegood might join in. Her unique perspective and her own form of magic could be useful in the rebellion. Neville Longbottom, having grown so much in courage over the years, would definitely be on Harry's side as well.
Hermione would surely support Harry. She's always been by his side, and with her intelligence and knowledge of magic and wizarding laws, she'd be a great asset. Ron would also be there, providing his loyalty and his own brand of courage.
His friends like Ron and Hermione would surely support him. They have been through a lot together, and they believe in Harry's leadership. Also, the Weasley family in general would be behind him. They have always been on Harry's side in his battles against the dark forces.
In such a fanfiction, Harry Potter might gather all the students and magical beings who are discontent with the current regime at Hogwarts or in the wizarding world. He could lead them to fight against unjust rules, like unfair treatment of house - elves or discriminatory laws against half - bloods and Muggle - borns.
Often, Harry Potter himself remains a central protagonist. He has a history of standing up against injustice, so it's natural for him to be at the forefront of a rebellion in fanfiction. His friends, like Hermione and Ron, are also common protagonists. Hermione's intelligence and Ron's loyalty make them great assets in any rebellion scenario.
His friends from Hogwarts like Hermione and Ron would most likely support him. They have always been by his side through thick and thin in the original story, so in the fanfiction, they would continue to support Harry in his fight against the Ministry.
The Order of the Phoenix members might also back Harry. They've fought against the dark forces before and if they see that the Ministry has become a threat, they'd side with Harry. Dumbledore's old allies in the Order would believe in Harry's judgment and join him in his mission to destroy the corrupt Ministry.
His closest friends like Sasuke would most likely support him. Sasuke, who has also seen the dark side of the shinobi world, would understand Naruto's reasons for rebellion. Also, Sakura, who has always been by Naruto's side, would be there to support him. Shikamaru, with his intelligence, might also see the need for change and back Naruto up.
Hermione would definitely support Harry. She's always been by his side, and she values justice and the proper use of magic and wizarding laws. She would see the wrong in a fanfiction that misrepresents Harry and would use her vast knowledge to help him in the lawsuit.
Hermione Granger would surely be one of the first to support him. She's always been by his side, helping him with research and providing intelligent advice. Ron Weasley would also be there, being Harry's loyal friend through thick and thin. Neville Longbottom could be another supporter. He's grown into a brave and capable wizard, and he would stand with Harry in his new role. Dumbledore, if he were still alive in the fanfiction, would likely offer his wisdom and guidance to Harry as he takes on this new and important role.
One main character could be Griphook. He already has a complex relationship with Harry Potter in the original series. In a goblin rebellion fanfiction, he could be a key figure leading the goblin revolt, using his knowledge of the wizarding world and his own skills to strategize against the wizards. Another character could be a young goblin apprentice who is caught between his loyalty to his own kind and his admiration for Harry Potter and the wizarding world.
His best friends Hermione and Ron would most likely support him. Hermione with her intelligence could come up with great strategies, and Ron, being loyal, would stand by Harry no matter what.
