Themes also play a big role. Some fanfics explore themes like redemption, power corrupts, or the struggle between different forms of morality. In an alucard crossover with 'Fullmetal Alchemist', themes of sacrifice and the cost of power can be explored through Alucard's interactions with the characters in that universe. The way these themes are weaved into the story can make it a truly great fanfic.
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 needs to be engaging. It should have a clear goal or conflict. Maybe Alucard is on a quest in the new universe, or he's being hunted by the local authorities. A well - paced plot that doesn't drag and has enough twists and turns to keep you reading is a must. In a crossover with 'Star Wars', perhaps Alucard gets caught in the middle of the Jedi - Sith conflict, and how he navigates that situation is what makes the story exciting.
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 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 fanfiction should stay true to the essence of each character. Naruto's never - give - up attitude, Alucard's vampiric powers and his complex personality, and the unique traits of the Hellsing characters like Integra should be maintained. If they are written out of character, it can really take away from the enjoyment of the fanfiction.
Character interactions are key. You want to see how the characters from different shows blend together. For example, if it's a crossover with Scooby - Doo, seeing how Shaggy and Dipper would react to the mysteries in Gravity Falls. Also, a good plot that makes sense for both universes. It can't just be a random mash - up.
