Internally at Hogwarts, it could change his relationship with other teachers. Some teachers might be grateful for Umbridge's departure and side with Snape more, while others who were on Umbridge's side (if there were any) would be against him. This could create a more complex political situation within the school faculty.
Snape could face some backlash from the Ministry. If they find out that he was involved in getting rid of Umbridge, they might try to find ways to punish him or at least keep a closer eye on him. However, his skills at subterfuge would likely help him avoid any serious consequences.
In some versions, Snape uses his knowledge of the Dark Arts and Hogwarts' secrets. He might set up a situation where Umbridge is lured into a restricted area of the castle and gets into trouble with some magical creature or ancient magic, causing her to be removed from her position.
In some fanfictions, Harry discovers a long - forgotten magic charm that has the power to make a person's worst nightmares come true. He uses it on Umbridge, and she is so terrified by the nightmares that she runs away from Hogwarts. The charm could be something that is based on the person's deep - seated fears, and for Umbridge, it might be related to losing her power and being publicly shamed.
One consequence is a change in his physical strength. Kurama provided Naruto with a huge boost in power, so without it, he might not be as strong in terms of brute force. However, this could also force him to become more strategic in combat.
Well, if Harry gets rid of Snape, he might face backlash from the Slytherin house. Snape was a Slytherin and had his supporters there. They could make Harry's life difficult in various ways, like spreading rumors or trying to undermine his achievements. On the other hand, Harry might find new allies. Those who were secretly afraid of Snape but couldn't do anything might now side with Harry. But he also has to be careful not to let this new - found power go to his head, or he could end up making more enemies in the long run.
In some fanfictions, Harry might use his powerful magic skills, like advanced spells he's learned secretly, to outwit Umbridge. For example, he could create a series of complex illusions that confuse her and lead her to leave Hogwarts on her own.
Well, he could use the power of friendship. Maybe with the help of his friends like Hermione and Ron, they come up with a plan. They might find evidence that Snape has been involved in some really bad things that go against the wizarding laws. Once they present this evidence to the proper authorities, like Dumbledore or the Ministry of Magic, Snape could be gotten rid of. Also, Harry might have some sort of prophetic dream that gives him the key to getting rid of Snape, just like he had dreams about Voldemort in the original series.
One interesting plotline could be a battle of wits within the Hogwarts faculty. Snape, with his deep knowledge and sly nature, tries to outmaneuver Umbridge's strict and often cruel regime. For example, he might secretly undermine her rules in ways that only the students and a few other faculty members notice.
However, Umbridge can also be a popular character in these fanfictions in a different way. She is the perfect villain. Her over - the - top cruelty and her self - righteous attitude make her a great antagonist. Writers can really explore her nastiness and how the other characters react to her, especially Snape who has his own way of dealing with her.
One possible reason could be that Snape still has an underlying sense of loyalty to Dumbledore. Since Dumbledore cares about Harry, Snape might step in to save him from Umbridge's cruelty. He doesn't want to see Hogwarts turned into a place of unjust persecution under Umbridge's regime, and Harry is a symbol of the resistance against that.
Well, it could be that Ned wants to distance himself or the story from the fanfiction involving Septa Mordane for various reasons. Maybe it doesn't fit the overall narrative or tone he has in mind for the official story.
