Annabeth could be developed differently in fanfiction by having her face her own insecurities more directly. In the original, she's very confident in her abilities. But in fanfiction, she could have moments of self - doubt. For example, when they face a really difficult challenge, she might think she's not smart enough. This shows a different side of her character and makes her more relatable.
In fanfiction, their characters might be developed with more emotional depth. For instance, Percy could be shown to be more vulnerable about his feelings for Annabeth. Maybe he has nightmares about losing her and this makes him more protective in a different way than in the original. He might be more open about his fears, which wasn't really explored as much in the original.
In fanfiction, their relationship could be developed in a more complex way. In the original, their relationship is building, but in fanfiction, it could be more tumultuous. For example, they could have a big argument over a decision Percy makes during a quest. This argument could lead to them both growing and understanding each other better, which gives a different spin on their characters compared to the original.
Percy could be developed as a more brooding and conflicted character. His powers might be darker and less controlled, which makes him a danger to those around him, including Annabeth. Annabeth, on the other hand, could become more determined and a bit more ruthless in her attempts to save Percy from his dark self.
He could be more brooding. Since Pluto is associated with the Underworld, Percy could have a darker, more introspective side. He might spend a lot of time thinking about the nature of death and the afterlife.
Maybe she's just curious. She wants to see how fans are interpreting the world she's a part of.
I'm a big fan of Percy in fanfictions. He's always so brave and resourceful. In many fanfictions, he gets to show even more of his humorous side, which makes him really likable.
In fanfiction, Roxas might be developed to have more complex emotions about his existence. For example, he could struggle more with his identity as a Nobody and his connection to Sora in ways not fully explored in the game. Xion, on the other hand, could be given more backstory about her creation. Maybe the fanfiction delves deeper into the experiments that led to her existence.
Another plotline might involve Percy and Annabeth getting lost in an alternate dimension within the world of 'The Lightning Thief'. In this dimension, the rules of the gods are different. They have to figure out how to get back while also dealing with strange creatures and challenges that test their relationship and their understanding of the mythological world.
She could be more in tune with her femininity, using it as a strength rather than a hindrance. For example, she might be more perceptive about emotions, both her own and others', which could help her in diplomatic situations with the gods. Instead of the more straightforward and sometimes brash approach of the original Percy, Fem Percy could be more subtle and strategic.
Well, in fanfiction, their relationship might bring out different aspects of their personalities. Since they are married, Tony could be more protective and less of the joker he was in the original show. Ziva, on the other hand, might be more open about her emotions, especially when it comes to her relationship with Tony. This is different from the original show where she often kept her feelings bottled up. The married state in fanfiction gives them a new environment to grow and change as characters.
For fem Kuroko, her character could be developed with more emphasis on her femininity. She might use her charm or intuition in ways that male Kuroko didn't. For example, she could be more in tune with the emotions of her teammates and use that to boost team morale. Aomine, on the other hand, as a female could be developed with a different kind of competitiveness. Instead of just brute strength, she might use her intelligence and strategic thinking more, like finding ways to outwit opponents through psychological warfare.
One way their characters are developed differently in fanfiction is through their parenting styles. In the original series, since they die early, we don't really see them as parents. But in fanfiction, we can see different approaches. Minato could be the strict yet loving father, teaching Naruto advanced ninjutsu from a young age. Kushina could be the nurturing mother, always making sure Naruto is emotionally okay. Additionally, their characters can be developed in relation to the political situation of the village. They could be involved in secret political maneuvers to protect the village and Naruto's future as a potential great ninja.
