Well, in the fanfiction world, if Snape turns into a baby, it could be really chaotic. His colleagues at Hogwarts might be extremely shocked. Maybe Dumbledore would have to take on the role of caretaker, trying to figure out how to reverse the spell. And Harry Potter would probably be very confused seeing his former strict professor as a helpless baby.
Well, first of all, there's the initial discovery of Snape as a baby. This causes a stir in the wizarding world. His enemies might see it as an opportunity to take advantage, while his friends (if he has any left in this state) will try to protect him. As the story progresses, there could be attempts to communicate with baby Snape, who may or may not retain some of his adult memories or magical abilities. The plot could then revolve around finding a cure, which could involve dangerous quests, ancient spells, or encounters with mysterious magical creatures. It's a really rich area for fanfiction writers to explore different aspects of the Harry Potter universe through this unique transformation.
One idea could be that in this fanfiction, Wolverine turns into a baby due to a powerful mutant's accidental spell. The X - Men then have to take care of him while also trying to find a way to reverse the transformation. They might discover new aspects of Wolverine's personality as a baby, like his unwavering determination is now shown through his attempts to crawl towards danger.
One idea could be that a villain's new invention accidentally zaps Kim and turns her into a baby. Her sidekick Ron has to take care of her while also trying to find a way to reverse the effect. He might struggle with basic baby - care tasks like changing diapers and feeding her, all while keeping her safe from the villain who might want to take advantage of her weakened state.
One possibility could be that an akuma's power goes wrong and instead of attacking Chat Noir in a normal way, it turns him into a baby. Ladybug is then left to protect this baby Chat Noir while also trying to find a way to reverse the transformation. She might have to take him to Master Fu for help, all while hiding him from Hawk Moth who could potentially use this situation to his advantage.
One great fanfiction with this concept is 'Baby Dean's Adventures'. It has a really cute take on how the other characters deal with a baby Dean. They struggle at first but then it becomes a heartwarming story of protection and family.
One possible plot could be that Snape, after being hit by a strange spell during a battle in Hogwarts. As a woman, he (now she) would face different reactions from the students. Some might be more sympathetic, while others would be confused. She would have to deal with her own changed identity while still trying to teach Potions and keep an eye on Harry Potter, all the while trying to find a way to reverse the spell.
He might be initially suspicious. Snape is a complex character. He's used to being on his guard, especially with Gryffindors like Hermione. So, his first reaction could be to wonder what Hermione's real motives are for seeking his help.
One possible plot could be that the magic backfires on Voldemort during a powerful dark spell. As a baby, he has no memory of his previous self. The wizarding world is in chaos as they don't know what to do with this baby - voldemort. Some might want to kill him immediately, while others think he could be redeemed. Harry Potter, having defeated him once, feels a strange sense of responsibility and wants to make sure he doesn't grow up to be evil again.
Well, one possible plot could be that his friends have to take care of him. They might struggle at first, not knowing how to handle a baby Izuku. For example, Bakugo could be really frustrated but gradually learn to be gentle. Ochaco might be really good at soothing baby Izuku when he cries.
