Base her development on her backstory. Since she has a tough past in Fairy Tail, use that as a foundation. As a child, she might be haunted by memories of her early days. But as the story progresses, she can overcome those fears. For example, if she was once afraid of a certain type of magic because of something that happened in her past, she could face it and defeat it in the fanfiction, which would be a huge step in her character development.
First, know the character of Erza well. Understand her strengths like her great combat skills and her determination, as well as her weaknesses. Then, come up with an interesting plot. It could be something that builds on existing Fairy Tail storylines or something completely new. For example, you could have Erza face a moral dilemma that tests her loyalty to the guild. Also, use vivid descriptions of the magical world, the spells, and the battles.
In such fanfiction, it can show Erza's vulnerability. When she's in the shower, she's in a private moment away from her usually tough - as - nails exterior. This can reveal her softer side, like her insecurities or her hopes for the future. For example, she might worry about not being strong enough to protect her friends.
Erza could be developed by showing her vulnerability. Usually, she is very strong and composed. But in this situation, her being embarrassed and naked makes her more human. We can explore how she overcomes her insecurities and uses her inner strength.
No, it is not appropriate. Writing fanfiction that involves a character in a naked state is often unethical and goes against the respect that should be given to the original work and its characters. Moreover, it may also violate the terms of use of the platform if it is shared on certain websites.
These fanfictions can enhance the perception of Erza as a strong and resilient character. When she endures torture, it shows that she can withstand great pain and not break easily. For instance, if she's tortured by a powerful villain, but still manages to fight back or resist in some way, it makes readers see her as a formidable force.
One great 'Naruto' fanfiction is 'A New Path' which explores an alternate story for Naruto. For 'Fairy Tail' and Erza, 'Erza's Redemption' is quite interesting. It delves into her past and how she overcomes certain traumas. Another 'Naruto' fanfic could be 'The Hidden Power' which gives Naruto some unique abilities not seen in the original. These fanfictions are great because they expand on the original universes and characters in creative ways.
In fanfiction, a child of Natsu and Erza might inherit Natsu's fiery temper and love for adventure. They could also have Erza's strong sense of justice and discipline. Maybe they'd have Natsu's pink hair and Erza's beautiful eyes. And they'd probably be a powerful mage, combining Natsu's dragon slayer magic with Erza's requip magic.
You can try fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Fairy Tail Erza x Erza Knightwalker' on their search bars, and you'll get a list of relevant fanfictions. Some might be really well - written with interesting plot twists.
First, think about the aspect of Little Erza you want to focus on. Is it her courage, her kindness, or her magical abilities? Then, come up with a simple plot. For example, if you want to focus on her courage, you could write about her facing a big, scary monster alone. Next, add some details about the setting. Maybe it's a dark forest or an abandoned castle. Also, don't forget to include her relationships with other characters from Fairy Tail. They can help or hinder her in her adventure.
The guild would be devastated. Natsu would probably be one of the first to be enraged. He'd vow to find whoever or whatever was responsible and make them pay. His fire would burn hotter than ever as he channels his anger.
