The fanfiction could involve Snape traveling back in time to the era of Merlin. There, he could meet Merlin and learn from him directly. Snape might be initially skeptical of Merlin's methods, but as he spends more time with him, he realizes that Merlin has a depth of magical knowledge far beyond what he had expected. They could work together on a magical project, like creating a magical shield around Camelot that can withstand the dark magic of Snape's time. Snape would then bring this knowledge back to his own time and use it to protect Hogwarts.
One possible plot could be that Snape discovers an ancient spell book related to Merlin. This spell book might contain knowledge that could help him in his mission to protect Harry Potter. For example, he could find a spell that would allow him to better conceal his true intentions from Voldemort. He might also learn about a long - forgotten potion that Merlin created which has the power to heal wounds that are otherwise considered fatal. Snape could then use this knowledge to save the life of a Hogwarts student during a battle.
A possible plot could be that Voldemort, in an attempt to find a new form of power, discovers the Teletubbies' world. He sends Snape there to investigate. Snape arrives and finds that the Teletubbies' world is full of positive energy that could be harnessed in a different way. However, the Teletubbies are so innocent and pure that Snape starts to have second thoughts about helping Voldemort. He then has to figure out how to protect the Teletubbies from Voldemort's clutches while also trying to find a way back to his own world. This plot could explore Snape's complex character in a new and unusual setting, as well as the clash between the dark magic of his world and the innocent magic of the Teletubbies.
Maybe in a time - travel fanfiction. Hermione travels back in time and ends up in Snape's student days. She tries to change some events for the better, and in the process, she gets to know a younger Snape. Their interactions are initially rocky but gradually turn into something more, leading to a kiss. This would be a very different take on their relationship, as it involves a different time period and different versions of themselves.
The plot could involve a magical artifact that has been stolen from the wizarding world and has somehow ended up in Diana's realm. Severus Snape is sent to retrieve it. When he meets Diana Prince, she initially mistakes him for a threat. But after some misunderstandings are cleared up, they decide to work together. Along the way, they discover that the theft of the artifact is part of a larger plan by a powerful and evil force that wants to use the magic in the artifact to gain control over both worlds.
Well, one possible plot could be that Death Eaters who suspect Snape of being a double agent kidnap him. They might take him to a secret lair and try to torture him for information. Snape, being as tough as he is, would hold his secrets as long as possible. Maybe Harry and his friends find out and embark on a rescue mission, having to face their former enemies to save Snape.
A possible plot could be that they are both trapped in a magical dimension. They have to rely on each other to find a way out. During this time, they share their stories and secrets. Snape reveals his true feelings about Lily, and Sirius tells about his family. This mutual sharing helps them see each other in a new light and forms the basis of their friendship.
Snape's character could become more complex. He might start to incorporate some of Merlin's wisdom into his own actions. For example, Merlin was known for his ability to see the good in people, and Snape could start to do the same. Instead of just being bitter and resentful towards Harry, he could start to see Harry as a potential ally in a greater fight, much like Merlin saw the potential in the young knights of Camelot.
One possible plot could be that Severus Snape, through some magical mishap, is transported to the Naruto universe. He could initially be seen as a strange and powerful new ninja. Snape's skills in potions could be translated into some unique form of chakra control or ninja art related to elixirs. He might end up teaching some of the younger ninjas, like Naruto and his friends, about different ways of thinking and approaching problems, much like he did in Hogwarts.
In this fanfiction, the story could start with Harry finding Snape in a very vulnerable state after the Battle of Hogwarts. Harry feels a deep sense of guilt for how Snape was treated throughout his life. So he decides to adopt him. At first, their relationship is awkward. Snape is still his old sarcastic self, but Harry is determined. As time passes, they discover they have a lot in common. They both lost their parents at a young age, and they both had to face great challenges. This newfound understanding leads to a transformation in their relationship. Harry helps Snape to come out of his shell of bitterness, and Snape teaches Harry more about the Dark Arts in a controlled and ethical way so that Harry can better protect the wizarding world in the future.
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.
Well, perhaps the plot could start with Snape having some sort of magical transformation that allows him to carry and give birth to Harry. Then, as Harry grows up, Snape would have to deal with his own dark past while trying to protect Harry from the same fate. He might be a strict but loving mother, teaching Harry both light and dark magic in a more balanced way than in the original story.
