In the Harry Potter fanfiction where Harry Potter gets rid of Snape, how does he manage to do it?

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.

On the other hand, Harry could be proud of himself for standing up for what he believes in. He may think that he has made Hogwarts a better place by getting rid of a teacher who was not treating students fairly. But at the same time, he might have mixed emotions as Snape was also an important part of the Hogwarts environment for so long.

In some fanfictions, Snape might use his advanced knowledge of potions to create a special concoction to heal Harry. He could draw on his skills in Herbology as well to find rare ingredients for the potion.

He uses his knowledge of the castle's secret passages. By using these, he can quickly disappear after a prank. For example, if he turns Snape's quills into snakes during a class, he can run into a passage right behind his seat and be gone before Snape realizes who did it.

In many fanfictions, Harry might use his powerful spells like the Stunning Spell or the Killing Curse if the story allows for such dark magic use. He could also use his intelligence to outwit the dragon, perhaps finding a weakness in its armor or behavior pattern and then using a well - timed spell to defeat it.

Well, in some fanfictions, Harry might use a super - powered Patronus. His Patronus could be stronger than usual, perhaps due to some newfound magic or a special connection he has developed. It could be so powerful that it simply overpowers the dementors and destroys them.

He probably uses magic. For example, to water the plants, he can use a spell instead of a regular hose. And to fence the ranch, he might use a charm to create a magical barrier that can keep unwanted animals or people out.

In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.

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.

Maybe he discovers some ancient spells or incantations that don't need a wand. These could be spells that were forgotten over time but are still effective. He spends time researching in old books and uncovers these wand - less magic techniques.
