The unique aspect is the combination of two very different universes. RWBY has its own complex world with Grimm, Dust, and Huntsmen, while Sonic has his high - speed adventures. In fanfiction, seeing Sonic's speed in the RWBY world is really cool.
A common theme is the clash of different powers. Sonic has his super speed and unique abilities, while the RWBY characters have their own semblances and combat skills. The fanfictions often explore how these powers interact when they meet. For example, how Sonic's speed can be used against the Grimm or in battles with RWBY villains.
There might be a fanfiction where Sonic teams up with Ruby Rose. Since they both have a sense of justice and a determination to protect, they could go on adventures together, with Sonic's agility and Ruby's scythe - wielding skills making for an exciting combination. For example, they might face a new type of enemy that requires both their unique abilities to defeat.
I really like 'Sonic's Adventure in Vale'. In this fanfic, Sonic arrives in Vale and quickly gets involved with the Beacon Academy students. The story does a good job of showing how Sonic's personality clashes and also gels with the RWBY characters. It has some exciting action scenes and a touch of humor as Sonic tries to understand the ways of Remnant.
One popular RWBY and Sonic fanfiction is 'Sonic in Remnant' where Sonic gets transported to the RWBY universe. It has great action scenes and interesting character interactions.
There's also 'Sonic meets RWBY: A Chaotic Crossover'. In this one, Sonic's speed and abilities are pitted against the Grimm in a really exciting way. It delves into how Sonic's presence changes the dynamics in the RWBY universe. The author does a great job of integrating Sonic's world elements, like the Chaos Emeralds, into the RWBY story.
A fanfiction could explore a friendship between Sonic and Blake. Blake, with her mysterious past and her love for books, could be intrigued by Sonic's world. They could share stories about their respective homes and adventures. Sonic could also help Blake face her inner demons by using his positive attitude and his ability to keep moving forward no matter what.
First, you need to understand the universes of both Sonic and RWBY well. Know the characters, their abilities, and the settings. For example, Sonic's speed and the different zones in his world, and RWBY's Huntsmen, Grimm, and the four kingdoms. Then, come up with an interesting plot that can combine these two worlds in a unique way. Maybe Sonic gets lost in Remnant or the RWBY team has to travel to Sonic's world for some reason.
Sonic is typically portrayed as the heroic, fast - running blue hedgehog we know from the games. He is kind - hearted and always ready to save the day. Sonic exe, on the other hand, is often depicted as a much darker and more menacing version. He might have a corrupted appearance and different abilities that are more in line with causing chaos rather than preventing it.
In a Metal Sonic x Sonic Fanfic, the action and adventure aspects can be really exciting. Writers may create new challenges for Sonic and Metal Sonic to face together or against each other. For example, they could be forced to team up to defeat a greater evil that threatens their world. This kind of fanfic also gives a chance to delve into the emotions of the characters. Metal Sonic, although a machine, might show signs of evolving emotions or at least a form of artificial intelligence - based loyalty or rivalry towards Sonic.
