In a 'Severus Snape meets Naruto' fanfiction, Snape could be summoned by Orochimaru for his knowledge of dark magic, which Orochimaru mistakes for some kind of powerful ninja jutsu. Snape, being the complex character he is, might play along for a while to figure out what's going on. Along the way, he meets Naruto and is intrigued by his unwavering spirit. He then decides to help Naruto against Orochimaru, using his magic in ways that seem like new and mysterious ninja techniques to the Naruto characters. This would lead to a lot of interesting interactions between the characters from two very different universes.
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.
One possibility is that Naruto gets transported to the world of Harry Potter where he meets Snape. Naruto's energetic and positive attitude could clash with Snape's brooding nature. However, they might find common ground in their loyalty to their respective friends and causes. Naruto could show Snape the value of perseverance in a different light, and Snape could introduce Naruto to the complex world of potions and magic.
One possible plot could be that Harry, through some time - traveling magic, meets young Severus. Harry, knowing Severus' future, tries to befriend him and change his path. He could introduce Severus to different ways of using magic that are less dark - oriented, which might change Severus' perception of magic and his future relationships in Hogwarts.
At the start, Snape would likely be quite suspicious of Naruto. He's used to a world full of secrets and might think Naruto is some sort of threat or spy. Naruto, being Naruto, would keep trying to break through Snape's cold exterior. He might start by complimenting Snape's skills in potions or magic. As time goes on, Snape might see Naruto's good heart and start to open up a bit more. They could end up having some interesting conversations about power, loyalty, and friendship. Naruto could tell Snape about his bonds with his friends in the ninja world, and Snape could share some of his own experiences with the Marauders from his school days.
Naruto would likely be more powerful in a physical combat sense. His training as a ninja has made him extremely strong, fast, and able to take a lot of damage. He also has the Nine - Tails' chakra at his disposal. But Severus Snape is no slouch. His knowledge of magic is extensive, and he could potentially use magic to outwit Naruto. For example, he could use spells to create illusions or disable Naruto's movements. However, Naruto has shown great adaptability in combat, and his willpower is unrivaled. So overall, Naruto's physical and spiritual power might give him the edge.
Perhaps Snape could help Albus Severus come to terms with his family legacy. Albus Severus is named after two great wizards, Albus Dumbledore and Severus Snape. Snape could share his own experiences of being in the shadow of great names and how to carve out one's own identity in the wizarding world. This encounter could be a very emotional and character - building moment for Albus Severus.
Well, Albus could finally understand Snape's true nature. Maybe he discovers the sacrifices Snape made for his family. He might apologize for any wrong assumptions he had about Snape in the past.
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.
One interesting story could be where Albus Severus discovers Snape's hidden kindness through a time - travel accident. He gets to see Snape's past and the sacrifices he made, which changes his perception of him.
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.
