One likely narrator could be one of Epsilon's closest comrades. For example, if it was someone like Church, who had a deep connection with Epsilon, they could be narrating their thoughts and feelings during and after his death. This would give an insider's perspective on the loss and the significance of Epsilon's role.
Another potential narrator could be an outsider looking in. Maybe a new character or someone who has always been on the periphery of the Red vs Blue group. They could be observing the reactions of the main characters to Epsilon's death and providing a different view, perhaps one that is more objective or that shows how the event impacts the broader community.
One common theme could be the exploration of loss and grief among the characters. Since Epsilon's death is a significant event, the fanfiction might focus on how the other characters in Red vs Blue deal with the emotional aftermath. They could be shown struggling to come to terms with his death, and there might be a sense of emptiness in the group dynamic.
The characters watching Red vs Blue fanfiction can be a way to expand the lore in a different way. Fanfiction often takes the existing story and characters in new directions. When the characters themselves are involved in this 'consumption' of fan - created content, it blurs the line between the official story and the fan - made interpretations. It can lead to interesting character development as they react to how others view them in these fictional stories.
One of the popular platforms could be Archive of Our Own (AO3). It has a large collection of fanfiction from various fandoms, including Red vs Blue. Another option might be FanFiction.net, which also hosts a significant amount of Red vs Blue - related fan works.
Ben Tennyson would probably be a main character, whether in his normal form or transformed into different aliens. He could be on either the red or blue side depending on the story's take.
Sasuke and Tex might be likely to be paired up. Both are strong and somewhat brooding characters. Sasuke's quest for power could be paralleled with Tex's own abilities and her role in the Red vs Blue universe. They might engage in some intense battles or even end up having to work together against a common enemy, leading to some interesting character development for both of them.
Another theme is the exploration of the sci - fi elements. Red vs Blue has a lot of cool sci - fi concepts, and in vol 9 fanfiction, writers might delve deeper into things like the technology used, the nature of the different simulations, etc. They might come up with new and interesting takes on how these elements work within the story.
Tucker is often a popular character. His unique sword and his somewhat cocky attitude make him stand out. Church is also quite popular. His sarcastic remarks and his mysterious backstory add to his appeal in these fanfictions. And then there's Caboose. His naive yet endearing nature can create some really interesting interactions, especially when paired with the more serious or battle - hardened characters from the Death Battle universe.
Ruby and Church could form an alliance. Ruby is always eager to make new friends and fight for what's right. Church, despite his snarky attitude, has a good heart deep down. They could bond over their leadership roles in their respective teams and share their knowledge about combat and strategy.
Yang and Tucker could also work well together. Yang is strong and confident, while Tucker has his own brand of bravado. They could get into all sorts of adventures and battles, with Yang using her brawler style and Tucker with his sword and unique abilities. Maybe they'd compete for who can take down the most enemies in a fight.
They might be really amused. RWBY characters are used to their own crazy adventures, but seeing the unique humor and situations in Red vs Blue fanfiction could be a whole new level of entertainment for them.
