One challenge is maintaining the integrity of Artorias' character. He has a very distinct personality and set of abilities in the Dark Souls lore. Writers need to make sure he stays true to that in the crossover.
There's also the matter of pacing. In a crossover, there are often multiple storylines to follow. You have to balance the time spent on Artorias' journey in the new world, his interactions with new characters, and still keep the overall story moving forward at a good pace. If you focus too much on one aspect, like his battles, and not enough on character development, the fanfiction can feel unbalanced.
How about a crossover with the Berserk universe? Artorias would find himself in a world full of demons and apostles. His skills as a warrior would be put to the test against the likes of Griffith and his army of demons. His abysswalker abilities could give him an edge in combat, and he could also form an unlikely alliance with Guts.
A common theme is the exploration of different universes. Artorias, being from his own world, gets to experience new places, rules, and cultures in crossover fanfictions. Another theme is power - up or adaptation. He often has to adapt his skills or gain new ones to survive in the new crossovers. For example, in some fictions, he has to learn new magic systems.
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.
