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.
A common theme is self - discovery. Bakugou, now as a girl, has to figure out who she is in this new form. Another theme is acceptance, both self - acceptance and acceptance from others like his friends and family.
One common theme is the struggle of identity. Bakugou is a strong - willed character, and when he turns into a zombie, he has to deal with losing that sense of self. Another theme is friendship. His friends will try to save him or at least come to terms with what he has become.
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 main theme is cuteness. Writers often focus on making baby Bakugou as adorable as possible, with his chubby cheeks and tiny hands. For example, in many fanfics, he'll be toddling around and getting into harmless mischief.
I've heard of 'When Bakugou Becomes a Zombie'. This fanfic focuses a lot on the emotional aspect. It shows how his transformation affects not only him but also those around him. His classmates struggle with the idea of having to fight him or try to find a cure, which creates a lot of drama and interesting relationships.
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.
