Fanfiction: Severus Snape Never Joins Voldemort. What could be the possible plot twists in such a story?

In some fanfictions, Snape might be working with Voldemort because he has been blackmailed. Voldemort could have found out some deep, dark secret about Snape and is forcing him to cooperate. This could be related to Snape's past or something he has done that he doesn't want to be made public.

Well, it would be a lot less antagonistic. Without the whole Death Eater past and the spying for Dumbledore while seeming to be on Voldemort's side, Snape wouldn't have that built - up resentment towards Harry. He might actually see Harry as a talented young wizard worthy of proper mentorship, instead of constantly being so harsh on him.

One possible plotline could be that Snape discovers a hidden weakness of Voldemort. Maybe through his years of spying, he finds out that a certain spell, when combined with an ancient magic artifact, can destroy Voldemort. So he devises a plan to get hold of the artifact and uses the spell at a crucial moment when Voldemort is off - guard, perhaps during a major battle when Voldemort is focused on other opponents.

One possible plot twist could be that Snape's secret family has a hidden magical ability that is crucial to the wizarding world. Maybe his family has the power to reverse dark magic spells, and this is something Voldemort has been searching for all along.

Power. Voldemort might see Snape as a means to gain more power. Snape is highly intelligent and skilled in the Dark Arts. By caring for him, Voldemort could be ensuring that Snape remains loyal and continues to use his skills for Voldemort's benefit.

The plot could take a really interesting turn when it comes to Voldemort. Since Snape is raising Harry, he might train Harry in a way that Voldemort doesn't expect. Maybe Harry would be more of a spy in the dark side's camp. Snape could also use his position to mislead Voldemort about Harry's true abilities and intentions. This would create a whole new set of challenges and power dynamics in the fight against the Dark Lord. Harry's loyalties would be constantly tested, and his relationship with Snape would be even more crucial to the story.

A really interesting plot twist might be that Voldemort is being controlled by an even darker force, and Harry has to figure out a way to break that control while being held captive. Or perhaps Harry's friends, thinking he is dead, accidentally start a chain of events that end up helping Harry escape in a very unexpected way. For example, Hermione might cast a spell that was supposed to be for protection but ends up creating a portal right in Voldemort's lair.

One interesting plot twist could be that Severus Snape, as a 'king' in the fanfiction, discovers a long - lost magical art that gives him the power to change the past. This could lead to him preventing some of the tragedies that happened in the original Harry Potter story, like Lily's death. Another could be that he rules over a hidden magical realm where the rules of Hogwarts and the wizarding world as we know it don't apply, and he has to constantly defend this realm from dark forces that want to take over.

One possibility could be that Snape grows up in a different magical environment, perhaps in a small, hidden magical community that has its own unique way of teaching magic. He might develop his skills in potion - making and the Dark Arts in a more self - taught or community - guided way. Without the influence of Hogwarts, his relationships would be very different. He may not have the same intense rivalries or unrequited love for Lily Potter.

A great plot twist could be that younger Snape actually has some knowledge of Hermione's time - traveling. Maybe he's been having strange dreams about the future and when he meets Hermione, he realizes she's part of it. This would completely change the power dynamic between them.
