Well, in this fanfiction, Velvet is often portrayed as a character with great potential. When facing off against CRDL, her unique abilities can really shine. For example, her photography - based Semblance can be used in very creative ways during the fight, perhaps to create distractions or even to enhance her own combat skills in some unforeseen ways.
One common theme is friendship. Since CRDL is a team, many fanfics explore how the members interact and support each other as friends. Another theme is growth. The characters are often shown developing their skills and personalities over time.
One interesting RWBY Team CRDL fanfiction could be one that focuses on their training days at Beacon Academy. It might explore how they interact with other teams during practice battles, like how they strategize against teams like RWBY or JNPR. Maybe in this fanfiction, they start off as the underdogs but through some unique training methods they improve and gain more respect from their peers.
It's hard to say exactly where Pyrrha is without knowing more about the fanfic. She could be in a distant land, trapped in a dangerous situation, or simply lost and trying to find her way back.
One I like is 'The Adventures of CRDL in Remnant'. It shows the team in various situations across the world of Remnant. It's full of action and also has some really funny moments that lighten the mood while still maintaining the essence of the RWBY universe.
A really interesting RWBY Pyrrha fanfic is 'Pyrrha: The Untold Stories'. This fanfic explores her backstory in more detail, like her early days at Beacon Academy and her relationships with her classmates before the main events of RWBY. It gives a lot of depth to her character.
First, understand the characters. Know that Cardin is often the bully of the group, but there's more to him. Russel, Dove, and Sky also have their own personalities. You can start with a unique plot idea, like a mystery they have to solve. Maybe something related to an ancient relic in the RWBY world.
One possible fanfiction idea could be that Cinder and Pyrrha are long - lost sisters separated by some dark event in their past. In this fanfic, Cinder could be on a journey of redemption after realizing her sister is Pyrrha. Pyrrha, on the other hand, might struggle with the idea at first but then come to accept Cinder. Their relationship could develop as they face common enemies in the RWBY universe.
One common theme is her heroism. Many fanfictions explore how Pyrrha was always ready to sacrifice herself for the greater good. Another theme is her relationships, like her friendship with Jaune or her mentorship with the other characters. Loss is also a big theme, as her death was a significant event in RWBY, and fanfictions often deal with how the other characters cope with it.
