Well, they might be shocked. In the RWBY universe, the concept of betrayal is quite serious. If it's a Rose character being betrayed, the team could first show disbelief. They trust their comrades deeply, so this would be a huge blow to their morale.
They could also become angry. Ruby, for example, is a passionate character. If someone she cares about (from the Rose family perhaps) is betrayed, she'd be furious. She might even go on a quest for revenge, or at least seek justice for the wronged party.
They might be shocked. In many cases, when a character like Jaune is betrayed in fanfiction, the RWBY characters could initially show disbelief as they've come to know him. It would disrupt their view of the group dynamic.
They might be surprised by the complex and often dark themes in Warhammer fanfiction. RWBY characters are used to their own universe's rules and aesthetics, so the gritty and elaborate world of Warhammer could be a shock.
They might be amazed at the unique skills. For example, Ruby could be excited to see some super - fast combat skills as she herself values speed in battle.
It could be an enemy in disguise. Maybe a Grimm has managed to infiltrate their ranks in a clever way and then betrays the Rose character. Grimm are known for their devious ways and this would be a very RWBY - like scenario.
Perhaps they would show excitement when seeing their favorite characters in intense battles as depicted in the 'rwby reacts deadliest warrior fanfiction'. Since the 'Deadliest Warrior' concept usually involves some really cool and over - the - top fight scenes. And if the fanfiction is well - written, it can bring out a lot of emotions from the RWBY characters who are reacting to it.
They might be really shocked at first. The RWBY characters are from a different universe, and the Transformers are huge mechanical beings. Ruby, with her innocent nature, would probably be in awe of the Transformers' power and size.
They might be shocked at the creative interpretations in the fanfic. Since Angry Joe has a very distinct style, the RWBY characters could be taken aback by the way they are depicted in relation to him.
In the 'RWBY Reacts to Trail of Blood Fanfiction', the RWBY characters could have a wide range of reactions. Ruby, with her optimistic and heroic nature, might initially be in disbelief at the grimmer aspects of the fanfic. She would hope to find a way to turn the situation around. Weiss, being from a more refined background, could be quite vocal about her dislike for any unethical behavior or excessive violence. Blake, having seen her fair share of hardships, might be more empathetic but also critical. Yang, on the other hand, would be quick to defend any victims and would be outraged by any form of abuse or oppression in the fanfiction.
These different reactions based on their personalities would create a lot of tension and conflict within the fanfiction. It would also show the complexity of their relationships. For instance, Ruby's attempts at reconciliation might clash with Yang's more aggressive approach. Weiss's pride could make it difficult for her to forgive easily, while Blake's empathetic view could be a bridge between the two extremes. This all would make for a very interesting read in the fanfiction.
Well, they might be shocked at first. The characters in RWBY are all about loyalty in their own group, so seeing a 'Betrayed Rose' would be quite a jolt. They could start to question the motives behind the betrayal, whether it was for power, love, or something else entirely.
