They might be really surprised. Ruby, for example, could be excited to see all the different versions of Jaune. She loves new and interesting things, and this fanfiction would offer a whole new perspective on a character she knows. Yang might be more skeptical at first, but as she reads more, she could get into it and start making jokes about the different Jaunes.
Weiss could become more empathetic towards Jaune. If the fanfiction shows some versions of Jaune going through tough times or having different struggles, Weiss might soften her attitude towards him. She might start to see him as more than just the sometimes clumsy or over - eager guy she usually sees, and their relationship could become less prickly. Blake may find that she has more in common with Jaune than she thought. If the multiverse versions of Jaune have some elements of being an outsider or having to deal with complex identities, like she does, it could bring them closer together and make their conversations more meaningful.
Well, Jaune in RWBY fanfiction can vary a lot. Sometimes he's the underdog who overcomes huge challenges, and other times he might have unique powers or a special backstory.
It could be because Jaune is a relatable character. He starts off as a bit of an underdog in RWBY. So, fans like to write stories where the other characters notice his potential and become obsessed with him as he grows.
Obviously, Ruby, Weiss, Blake, and Yang are likely to be the main characters. Since it's RWBY - related, they would be the central focus as they watch the events in the multiverse. They are the ones whose reactions and interactions with the multiverse would drive the story forward.
Well, in 'rwby watching the multiverse fanfic', a cool concept is seeing how the RWBY characters react to their alternate selves. They might be shocked, inspired, or even envious. Also, the fanfic could explore how the different rules and physics of each multiverse affect the RWBY world. Maybe in one universe, Dust has completely different properties, and the characters have to adapt to that. And the idea of the characters being observers in the multiverse gives a unique perspective, as they can learn from other universes' mistakes and successes.
One idea could be that Ruby and Jaune are partnered for a special mission outside of Beacon. Ruby's speed and combat skills combined with Jaune's strategic thinking could make them a great team. For example, they might be sent to investigate a mysterious Grimm activity in a far - off village. Ruby can quickly scout the area with her speed, while Jaune plans their approach based on the information she gathers.
One possible secret could be about his family heritage. Maybe in the fanfiction, Jaune has a hidden connection to a powerful family in the RWBY universe that he's kept under wraps for some reason, like to avoid unwanted attention or because of some family feud.
His character could become more self - assured. Jedi are known for their confidence in their abilities, and Jaune might gain that as he masters Jedi - like powers.
