Well, they might be quite surprised. Some of the fanfictions could have really out - of - the - box ideas that they've never thought of before. They might find it interesting to see how fans interpret their characters and the RWBY universe in different ways.
Some popular RWBY Rooster Teeth fanfics include those that explore alternate universes. For example, there are fanfics where the characters have different semblances or team formations. Another type could be relationship - centered fanfics, like exploring the romantic relationships between different characters in more depth than what's shown in the original series.
They could gain new perspectives on their own characters. Fanfictions often explore different sides of the characters that may not have been fully shown in the original work.
They might be really surprised. Some of the fanfictions could have really out - there storylines that they never expected. They could find it funny to see how fans imagine their adventures and relationships in different ways.
They might start by reading them out of curiosity. Ruby, for instance, would probably be excited to see all the different versions of her story. She might share the interesting ones with her team.
Yang from RWBY might interact with the female characters from other Rooster Teeth shows. Yang is strong - willed and confident, and she could share her combat experiences with them. At the same time, she could learn new ways of handling different situations from these characters. For example, if she meets a character who is more strategic and less about brute force, it could be an eye - opener for her.
One idea could be a crossover where the RWBY characters are transported to a different Rooster Teeth universe and have to team up with the local heroes to defeat a common enemy. For example, they could end up in the world of 'Red vs Blue' and have to deal with the chaotic military situations there.

Ruby could interact with the main characters from Red vs. Blue. Maybe she tries to teach them some of her scythe - fighting techniques, and in return, they show her some of their military - style combat strategies. It would be an interesting exchange of skills.
One idea could be that the RWBY characters are transported to an alternate universe where they have to team up with Rooster Teeth's other original characters to fight a common enemy. Maybe a new type of Grimm that has some connection to a technology that Rooster Teeth characters are familiar with.
