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.
The change in Naruto's character. Usually, he's the go - lucky and sometimes clumsy ninja. But in these fanfics, when he gets serious, it's like seeing a whole new side of him. It makes the story more exciting as he approaches problems in a different way.
A third theme could be facing greater challenges. In these fanfictions, the challenges are so big that Luffy can't just rely on his normal, laid - back self. He has to be more serious to overcome them.
One great 'Harry gets serious' fanfiction is 'The Serious Side of Harry' on FanFiction.net. It shows Harry dealing with the weight of the prophecy in a very mature way.
A third theme could be self - discovery. As Natsu gets serious, he may also discover new aspects of himself. Maybe he realizes he has more power within him than he thought, or he discovers a different way of thinking about his role as a dragon slayer.

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.
I think Zoro's core personality of being tough and fearless would remain. However, being in a female body might make him a bit more aware of certain things, like how he's treated differently by some people. But overall, he'd still be the same Zoro who doesn't back down from a fight and is always looking to improve his skills.
Well, 'Serious Naruto: A New Era' is another good one. In it, Naruto is dealing with the aftermath of a great war and has to be serious in rebuilding the village. The story shows how he overcomes various challenges and grows not just as a ninja, but as a person. It also has some great action scenes that highlight his new - found seriousness.
Well, in such fanfiction, the storylines often delve deeper into the complex themes of the original 'Harry Potter' series. For example, they might explore the moral ambiguities of magic more thoroughly. It could also focus on the psychological development of the characters, showing how they grow and change in ways that the original might not have fully explored. Additionally, the fanfiction might expand on the relationships between characters, like a more in - depth look at the friendship between Harry, Hermione, and Ron, or the complex family dynamics of the Weasleys.
