Bellatrix Lestrange could also be a great antagonist. She could target their alliance as she is loyal to Voldemort. She might try to capture them to use as bait for other Order of the Phoenix members or to simply gain information about their plans to resist the Dark Lord.
One idea could be that Harry and Neville form an alliance to secretly train students in advanced defensive magic outside of Umbridge's notice during her reign at Hogwarts. They could use the Room of Requirement as their base.
I'm not sure specifically if there is a fanfiction titled exactly 'Harry is mad at Neville', but it's very possible. Fanfiction writers often play with different character dynamics. Neville is a character who has his own insecurities and growth throughout the series, and Harry also has his own emotional journey. A story where Harry is mad at Neville could explore their individual personalities and how they resolve their conflict.
Luna Lovegood could also be an interesting addition. Her unique perspective on magic and the wizarding world might bring new ideas to the group. For instance, she could have insights about some of the more mysterious magical creatures or phenomena that they come across, which could be crucial in their quests or battles.
In this fanfiction, Harry and Neville could support each other through all the challenges at Hogwarts. For example, Neville could help Harry with his Herbology studies, which Neville is quite good at. And Harry could give Neville confidence in facing his fears, like standing up to the bullies. Their friendship would be a source of strength for both of them.
Most likely not. Fanfiction that involves abuse themes, especially when it comes to beloved characters like Neville and Harry from Harry Potter, is not appropriate. It goes against the positive values and spirit of the original series.
Yes, there are quite a few interesting ones. You can start by looking on fanfiction.net. Some of them explore how their relationship as brothers would change the story's dynamics, like in adventures at Hogwarts or during the fight against Voldemort.
One great 'Harry Potter Neville' fanfiction is 'The Redemption of Neville Longbottom'. It shows Neville's journey after the war, dealing with the aftermath and his newfound confidence. It's really well - written and gives Neville more depth.
I'm not entirely sure specifically what a 'Neville Harry Abused Fanfiction' would be about as it's not a common, well - known type. It could potentially involve dark and disturbing themes of abuse involving the characters Neville and Harry from the Harry Potter universe, but without reading it, it's hard to say precisely.
Another theme is loyalty. They are both loyal to their friends and to Hogwarts. Fanfictions often explore how this loyalty is tested, like when they have to choose between following the rules and doing what they believe is right. In some stories, they have to protect each other from false accusations within the school, showing their unwavering loyalty.
