Character development is really important. In a crossover RWBY fanfic, the characters from both universes should grow and change in a believable way. Also, the fanfic should respect the original lore of both RWBY and the other universe involved. For example, if it's a RWBY and Star Wars crossover, the use of the Force should be in line with the Star Wars rules while still fitting into RWBY's world. Additionally, the writing style should be engaging and easy to follow, with good dialogue that sounds natural for the characters.
One key element is how well the two universes are blended. For example, if it's a RWBY and Marvel crossover, the powers and personalities of the Marvel characters should fit well into the RWBY setting. Another is the plot. It should be engaging and not just a simple mash - up. For instance, a good plot could involve a common threat that both universes need to face together.
The originality of the concept matters a great deal. A good crossover RWBY fanfic will take the two universes and create something new and exciting. It could be a new power combination, a unique relationship between characters from different universes, or a fresh take on a common trope. Also, the fanfic should have a good pacing. It shouldn't rush through important events or drag on too long in uninteresting parts. And of course, it should be free of major plot holes that could break the reader's immersion in the story.
Characterization is crucial. A good fanfic will keep Alucard's core traits intact. His aloofness, his terrifying power, and his complex moral compass should be there. Also, how the other characters from the crossover universe react to him is important. For example, if it's a crossover with a more light - hearted universe like 'My Hero Academia', seeing how the optimistic heroes deal with Alucard's darkness is interesting.
The plot should make sense in both universes. If Iron Fist is crossing over into the Doctor Strange's world, the magic and martial arts elements need to be blended well. The story can't just force the crossover but should have a plot that justifies why these two different worlds are colliding. It might involve a common threat that only they can face together by combining their unique abilities.
First, look for how well the two universes are merged. For example, if it's a Witcher 3 and Harry Potter crossover, see if the magic systems are explained in a way that makes sense. Second, the characterization. Geralt should still act like Geralt. Third, the plot. It should be engaging and not just a random mash - up of the two worlds.
First, look for a well - written Sesshomaru. He should be in - character, not just a shell of his original self. The world - building of the crossover is crucial too. For instance, if it's a crossover with a different anime, how the two worlds blend together seamlessly. Another aspect is the relationships. How Sesshomaru interacts with the new characters from the other universe, whether it's a friendship, an alliance or a rivalry.
The plot needs to be engaging. A good Buffy crossover fanfic will have a plot that makes sense for both universes. It can't just be a random mash - up. For instance, if it's a Buffy and Star Trek crossover, the reason for their meeting should be related to a significant threat that both universes can be involved in.
The plot should be engaging. A good crossover fanfic will have a plot that combines the elements of both universes in a seamless way. For instance, if it's Dexter crossing over with a fantasy world, the mystery or crime aspect of Dexter's world should blend well with the magic or other elements of the fantasy world.
The respect for the source materials is crucial. The Witcher has its own lore, and so does the other universe in the crossover. For example, in a Witcher and Warcraft crossover, the author should not distort the basic concepts of either. The development of new relationships is also something to look for. How do the characters from different universes form bonds or rivalries? And the creativity in combining the magic or abilities from both universes, like in a Witcher and Final Fantasy crossover, is also very important.
The exploration of new themes is also important. In a cyberpunk and Tolkien crossover, you might see how the cybernetic enhancements in cyberpunk contrast with the more natural and magical elements of Middle - earth. And of course, a good plot. It should keep you engaged, whether it's about a character trying to save both worlds from a common threat or something else entirely.
The relationship between the self - insert character and the existing RWBY characters is a big factor. Whether it's a friendship, a rivalry, or something more complex, it needs to be well - developed. For instance, if the self - insert character becomes friends with Ruby, their interactions should show how they support and learn from each other. Also, the fanfic should respect the lore and world - building of RWBY. This includes things like the different kingdoms, the role of Huntsmen and Huntresses, and the significance of the Grimm.
The relationships are important too. Whether it's her relationship with her sister Yang, or her teammates Weiss, Blake, and the others. Fanfics that explore these dynamics in an interesting way are usually great. For instance, a fanfic that shows how Ruby's leadership affects the team's morale. And the writing style also matters. A clear and engaging writing style will make the fanfic more enjoyable to read.
