Well, perhaps an enemy uses a magic spell to turn Zoro into a baby as a way to weaken the Straw Hat Pirates. At first, the crew is in chaos trying to deal with a baby Zoro. But as time passes, they see that baby Zoro has a pure sense of determination. He still tries to train, albeit in a very clumsy and cute way. And in the end, they go on an adventure to find the antidote to turn him back, with lots of comical and touching moments along the way.
Well, one possibility could be that a magical spell goes wrong in the world of the fanfiction.

They might start by looking for ancient books in a hidden library that could hold the key to the solution.
Maybe it starts with a strange magical experiment gone wrong in Hogwarts. Harry is curious and gets too close, and suddenly he's a baby. The story could then focus on how the teachers, especially Dumbledore, deal with this situation. They might try to figure out if this is a new form of dark magic they haven't seen before. And Harry, as a baby, would have no memory of who he is, so it could also be about his friends trying to make him remember bits of his past life.
One idea could be that a powerful magic spell backfires on Ash. His friends then have to take care of baby Ash while trying to find a way to reverse the spell. They might face challenges like getting baby Ash to eat Pokémon food or stop him from toddling towards dangerous Pokémon.
Well, one possible plot could be that the other characters in the Solangelo universe are super confused at first. Percy might be all like 'Whoa, a baby Nico?'. They'd have to figure out how to take care of him. Maybe Will is the most determined to find a way to turn him back and in the process, there are some really cute and funny moments like baby Nico trying to grab Will's stethoscope and put it in his mouth.
In this fanfiction, the pregnancy could be a result of a deep emotional bond that developed between Zoro and Robin over time. The crew might be initially shocked but then very supportive. The baby could become a symbol of a new beginning for the Straw Hats. There could be challenges like protecting the baby from other pirates or the World Government who might see the child as a threat due to its parents' reputations. Also, the baby could bring out a softer side of Zoro and Robin, and they could learn a lot about themselves as they become parents.
The plot could revolve around Zoro and Nami keeping the baby a secret from their enemies at first. They are worried that their enemies might use the baby against them. As the baby starts to show signs of unique abilities, like being able to sense danger or having some kind of navigational sense like Nami, they realize they need to train the baby to be strong. So Zoro starts teaching basic self - defense skills while Nami teaches about the world and navigation.
One possible plot could be that Zoro, turned into a girl, has to deal with the different reactions of his crewmates. Some might be shocked, some might tease him. And he has to learn to adapt to his new physical form while still maintaining his tough fighting spirit.
One possible plot could be that Ash is turned into a Pikachu by a strange spell cast by a mischievous Pokémon. As a Pikachu, he has to figure out how to communicate with his friends. His Pokémon pals at first don't recognize him, but Pikachu - Ash starts using his old battle strategies in a new way. For example, he tries to direct Pikachu's electric attacks in the same patterns he used to direct his other Pokémon's moves in battles. Eventually, his friends realize it's him and they set out to find a way to reverse the spell.
Well, one possible plot could be Percy's struggle to adapt to his new female form. He might face challenges in how his friends and family react. For example, some friends might be confused or initially not accept the change. Percy would also have to deal with the different social expectations placed on girls in the story's setting. He could start to see the world from a different perspective, noticing things like gender - based discrimination that he wasn't aware of before.
Another possible main character could be a wise old mentor figure. This person might have knowledge about these strange transformations. They could guide Nico's friends or family in their quest to turn Nico back. Maybe this mentor has been around for a long time and has seen similar magic used in the past, so they know where to start looking for answers.
