It might be the unique plot. Maybe it takes the RWBY characters and puts them in situations that are different from the original series but still in - line with the overall RWBY universe.
I'm not sure of specific fanfics similar to it off the top of my head. But you could try searching on RWBY - dedicated fanfic websites like Archive of Our Own. There are likely to be fanfics with similar themes or tones.
War in the Red Dust was a novel with fantasy elements as its theme. It told the story of a mysterious world. There were many races in this world, and the most powerful ones were the demons and humans. The story of Zhan Hongchen revolved around two main characters, a swordsman with unique skills and a mysterious magician.
Swordsman Zhan Hongchen was a young man from a poor family, but he had a high talent in swordsmanship and a strong interest in magic. In an accident, he transmigrated to this world and became the protagonist of the conflict between the demon race and the human race. He constantly searched for the truth and gained a lot of valuable experience and growth in the struggle against the demons.
At the same time, the Magician Leng Shuang was also a good friend of Zhan Hong Chen. He was born into a mysterious family and had a strong magic talent. Leng Shuang and Zhan Hong Chen searched for the truth together and used their own magic in the battle against the demons, becoming important allies.
At the climax of the story, Zhan Hong Chen and Leng Shuang joined forces to defeat the most powerful enemy of the demon race, but they also discovered a series of secrets hidden in this world. In the end, Zhan Hongchen and Leng Shuang decided to explore these secrets together and protect the peace and tranquility of this world.
In this type of fanfic, the Infinity Stones could have a very different effect in the Harry Potter universe. For example, the Time Stone could be used to reverse dark spells or resurrect fallen wizards. However, the Stones' power might also be limited by the magic rules of the wizarding world. The fanfic could delve into how the characters from both universes adapt to the presence of the Stones and how they use or misuse their power.
Definitely. The Infinity Gauntlet comics came out earlier and laid the foundation for the concepts and characters seen in Infinity War. There are some differences, but the comics serve as a precursor.
Avengers Infinity War is largely based on the Infinity Gauntlet comic. Many key elements and plot points are drawn from it, but there are also some creative adaptations and additions to make it work for the cinematic universe.
First, decide what kind of fanfic you're interested in. Are you looking for something that focuses on a particular character like Iron Man or Captain America? Or do you want a story that explores a different ending for Infinity War? Once you know that, head to the fanfic platforms. On AO3, you can use the tags to filter the results. For example, if you want a story about Thor's journey in a fanfic, look for the 'Thor' tag. Then start reading the summaries to pick the ones that seem interesting.
