Well, some 'only human rwby fanfic' could revolve around team building among the characters without the use of their powers. Picture Yang trying to organize a sports team at Beacon Academy. It could also be about Jaune's attempts to learn cooking and host a dinner party for his friends. Also, fanfics might exist where Pyrrha is struggling with stage fright before a normal school play, which really shows her vulnerable human side.
You can start by looking on popular fanfic websites like Archive of Our Own (AO3). Just type in 'only human rwby' in the search bar, and it should bring up relevant fanfics. Another option is FanFiction.net. They also have a large collection of RWBY fanfics, and you can use the same search term to find the ones that are 'only human' themed.
Perhaps in the fanfic, there's a human who is a collector of rare weapons. When he hears about Crescent Rose, he becomes obsessed with adding it to his collection. He tries all sorts of devious methods to get his hands on it, like tricking Ruby or stealing it during a battle. However, his actions have consequences as the other RWBY characters come after him to retrieve the weapon.
One common theme is redemption. Since Salem is often portrayed as a villain, many fanfics explore the idea of her seeking redemption as a human. For example, she might try to make up for her past wrongs.
Penny would also have to adapt to the concept of time management in human society. In her robotic form, she could operate continuously, but as a human, she'd need to rest, eat, and sleep. This would mean learning to schedule her day around these new necessities.
One common theme is identity. The hybrids often struggle to figure out who they are, being part human and part Grimm. Another theme is acceptance. They have to deal with whether the humans or even the Grimm will accept them.
I think focusing on Ruby and Weiss would be good. Ruby as the leader has so many aspects to explore, like her insecurities and how she overcomes them. Weiss, on the other hand, has her own journey of breaking free from her family's expectations. They also have a great dynamic together, which can be developed further in the fanfic. But Blake and Yang are also important, especially if you want to show their friendship and how they support each other through tough times.
One popular character could be a young human adventurer. This character is brave and curious, always eager to explore new areas in the Pokemon - only - human world. They might start off as a novice but quickly grow in skills and knowledge, becoming well - known among other humans for their ability to handle difficult situations involving Pokemon.
Sure. One popular 'rwby grimm human hybrid fanfic' is 'Hybrid Origins'. It explores the unique concept of a character being part Grimm and part human in the RWBY universe. The story delves into how this hybrid deals with the challenges of being different in a world that is often hostile to anything related to Grimm.
A lesser - known but really engaging 'human Salem RWBY fanfic' is 'When Salem was Human'. This fanfic imagines Salem's life before she became the powerful and feared figure. It details her early days, her hopes and dreams, and how she might have been corrupted over time.
