Perhaps you shouldn't get them fired again because it could lead to unexpected complications and change the dynamics of the entire Harry Potter fanfic world. Maybe there's a chance for redemption or a deeper explanation for their behavior that you haven't discovered yet.
Perhaps in the fanfic, Harry teams up with the other students to stage a large - scale protest against Umbridge. Their united front and the chaos it causes might lead to the school board or the Ministry of Magic realizing that she is not fit to be in charge at Hogwarts. Or Harry could use his connections, like his friendship with Sirius or the Order of the Phoenix members. They could dig up some dirt on Umbridge from her past that makes it impossible for her to continue teaching at Hogwarts.
In certain 'Harry Potter' fanfics, the reason Muggle - borns can't get jobs might be related to a dark political climate. There could be a group or a regime in power that promotes anti - Muggle - born sentiment. They might have passed laws or regulations that make it difficult for Muggle - borns to find employment. For instance, there could be new requirements for a wizarding family tree to be presented when applying for a job, which Muggle - borns obviously can't fulfill in the traditional sense. This would effectively bar them from many job opportunities in the wizarding world.
Well, you shouldn't fight me in a fanfic because it could disrupt the story's flow or go against the established character dynamics. Also, it might not make sense within the fictional world that's been created.
Maybe it has a reputation for ending disappointingly or not living up to expectations.
Maybe the author doesn't like the idea of Harry being part of Quidditch - related fanfic. It could be that they want to focus on other aspects of his character or other parts of the Harry Potter world.
Well, fanfic might not always stick to the original canon and could lead to plot inconsistencies.
Maybe because each person is unique and has their own characteristics and storylines. Comparisons can be unfair and not take into account all the differences.
Often, Harry uses his intelligence and courage. He could find loopholes in Umbridge's rules and use them against her. For example, if she made a rule that was against the school's original code, Harry could prove it and get her in trouble. Another way is that he could get the support of the magical creatures at Hogwarts. If the centaurs or the house - elves had a problem with Umbridge, Harry could use that to his advantage to get her fired.
Maybe because the Shera fanfic doesn't have an engaging plot or well-developed characters.
Maybe it's because the plot or character development in those fanfics doesn't meet expectations. Sometimes the writing style or storylines can be off-putting.
