Another issue is the power scaling. If you cross Ranma 1/2 with a series like One Piece where the characters have superhuman abilities, you need to figure out how Ranma's martial arts stack up. You don't want to make him too overpowered or too weak compared to the new characters he's interacting with.
A major challenge in writing arcane crossover fanfiction is the fan expectations. Fans of both the Arcane world and the other universe you are crossing with have certain ideas and expectations. You need to satisfy both groups. If you deviate too much from what they expect, you might get a negative reaction. Additionally, world - building in a crossover can be a headache. You have to combine the rules of two different worlds, like the magic system in Arcane and whatever system exists in the other universe, and make it all make sense in the context of the story.
Another challenge is creating a plot that makes sense for both sets of fans. The story has to appeal to Destiny 2 fans as well as fans of the other game. If it's too focused on one side, the other group of fans might not enjoy it. For instance, if a crossover with The Elder Scrolls is too centered on Destiny 2 mechanics and doesn't incorporate enough of The Elder Scrolls' rich world - building, it could be a turn - off for Elder Scrolls fans.
One challenge is staying true to the essence of both the 'Survivor' format and the other franchise in the crossover. For example, if it's a 'Survivor' and 'Harry Potter' crossover, you need to make sure the magic system of 'Harry Potter' doesn't overshadow the survival challenges of 'Survivor'.
When writing these crossovers, pacing can be an issue. Since you're combining two different settings and storylines, you need to find a good rhythm. For instance, if you're doing a Fallout and Final Fantasy crossover, the more fast - paced action of Fallout and the often slower, more story - driven parts of Final Fantasy need to be blended well. And then there's the matter of making the crossover seem believable to the readers who are fans of both universes.
Character consistency is also difficult. In 'Scream', the characters have very distinct personalities. When bringing them into a new universe, their actions and reactions need to stay true to their original selves. For instance, Sidney's strong - willed and resourceful nature should be maintained even when she's facing new and different threats in the crossover story. And that's not easy when you're mixing different story elements and rules.
One challenge is getting the characterizations right. Since it's a crossover, you need to understand the essence of each character from both shows. For example, if you're crossing 'Scandal' with 'The West Wing', the political ideologies and working styles of the characters are very different. Another challenge is creating a believable plot that can merge the two universes smoothly.
One challenge is staying true to the lore of both franchises. For example, Gundam has its own set of mecha designs, technologies, and political backstories. When crossing over with another series like 'Mobile Suit Gundam Wing' and 'Cowboy Bebop', you need to make sure the Gundam elements fit into the Bebop universe without breaking its established rules. Another challenge is character development. You have to make the characters from different universes interact in a believable way.
Well, first of all, you need to have a good understanding of both Naruto's world and the world of the other series you're crossing over with. Let's say it's a Naruto and Final Fantasy crossover. You need to know how the magic and summons in Final Fantasy work, and how to integrate Naruto's ninja techniques. Also, pleasing fans of both series can be difficult. Fans of Naruto might have different expectations compared to fans of, say, the Witcher series when you do a crossover. You have to find a balance so that both groups of fans can enjoy the fanfiction.
One challenge is staying true to the original characters. For example, Carrie has very specific traits and a backstory. When crossing her over into another universe, like say, the Star Trek universe, you have to make sure her character still makes sense. You can't just change her personality completely.
Balancing the different universes' power scales is difficult. If Doomfist is crossed with a universe where the characters are much weaker, he could become overpowered and make the story uninteresting. Conversely, if he's in a much more powerful universe, he might seem insignificant. You have to find a way to make his abilities relevant.
