Well, in fanfiction, it often gives characters more backstory. For Percy, it might explore his life before he knew he was a demigod more deeply. Maybe he had some experiences as a child that influenced his later heroics. This helps to make the character more three - dimensional.
In such fanfictions, Percy's character is often explored through his resilience. For example, if he's physically abused, we see how he still tries to fight back or find a way to escape, which shows his determination. His loyalty also comes into play as he might not want to burden his friends with what he's going through.
Well, the character development can change a great deal. For one, a female Percy might be more in touch with her emotions. In the original, Percy was a bit of a typical male hero, but as a female, she could show more vulnerability and yet still be strong. For example, she might cry when a friend is hurt, but then use that emotion to fuel her fight against the enemy.
One interesting concept could be alternate family relationships. For example, a headcanon where Percy has a long - lost sister who also has demigod powers. This could add new dynamics to his story and how he copes with family issues in the demigod world.
Some fanfictions explore it through his leadership skills. They might write scenarios where Percy becomes the leader of all demigods and even some gods, leading them into battles against great threats. His strategic thinking and ability to inspire loyalty in others are enhanced, showing him as an ultimate being in terms of leadership. Also, his relationships with other characters are often deepened in fanfiction. For example, his friendship with Annabeth could be written in a way that it gives him additional strength or a special connection to Athena's wisdom, making him more powerful.
Well, in Naruto DNA fanfiction, character development can be explored through genetic mutations. For instance, a character might develop new powers due to a change in their DNA, which then changes their personality. They could become more confident if they gain a powerful ability from their DNA.
It shows growth in Oliver's character as he takes on more responsibility with the impending arrival of the baby. He might become less reckless.
Character consistency. A good Percy Jackson headcanon fanfic keeps the characters true to their original personalities. For example, Percy should still be brave and a bit of a smart - aleck, and Annabeth should be intelligent and strategic. If the characters act out of character, it just doesn't feel like a Percy Jackson story.
The blessing could make Percy more confident. Knowing that a major god like Apollo has blessed him gives him an extra boost. He might take on more challenges without hesitation, believing that he has the favor of the gods on his side.
Well, through transformation, characters are forced to adapt. For instance, if Marceline turns into a human - like form, she might have to deal with new emotions and physical limitations. This would make her more empathetic towards humans in the Land of Ooo, which is a big step in her character development.
In 'izuku bullied by sister fanfiction', Izuku's character development can be significant. The bullying forces him to become more resilient. For example, he may learn to stand up for himself more.
