Well, popularity is relative. In some fanfiction communities, they might be quite popular because they offer a different take on the well - known Death Battle concept. People who are interested in exploring the characters' relationships in a more...shall we say, 'intense' way might be drawn to these. But in the broader context of all fanfiction, they are probably not as well - known or widely read as other types.
Well, reactions to RWBY Death Battle fanfiction can vary greatly. Some might be excited about the unique battles and character match - ups depicted in the fanfiction. It could bring out new perspectives on the RWBY characters' abilities and how they would fare against each other in different scenarios. For example, seeing how Ruby's speed and scythe skills compare to another character's powers can be really thrilling.
Yes, she does. Her death is a significant event in the story and has a big impact on the plot and other characters. It's a turning point that adds depth to the narrative.

I'm not sure specifically what a 'akame deepthroat fanfic' is about as it could be highly variable. It might be a fan - created fictional work related to a character named Akame, but without further context it's hard to say exactly.
Yes, it likely exists. There are fanfiction for all sorts of combinations in the world of fandoms. Since both Spiderman and Death Battle are popular topics, it's very possible that someone has written fanfiction that combines the two, and Spiderman could be depicted as reading or being involved with such fanfiction within that fictional story.
