One challenge is maintaining the integrity of both universes. For example, if you're crossing over Harry Potter with Star Wars, you have to make sure that the rules of magic and the Force don't clash in a way that makes the story unbelievable. Another is character consistency. Each character has their own personality, and when you put them together in a new setting, you need to keep that intact.
One challenge is his negative attitude towards Harry in the original story. It's hard to suddenly make him into a love interest. Another is his mysterious side. Writers need to figure out how to make his secrets fit into a romantic relationship. Also, his loyalty to the Death Eaters at one point and then to Dumbledore later is a complex web that's difficult to untangle when writing a romantic scenario with Harry.
One challenge is merging the two different universes. Harry Potter has a world full of magic, with wizards, spells, and magical creatures. Peter Parker's world is more of a modern, urban superhero setting. Combining these two requires a lot of creativity to make it seem believable.
The challenges are numerous. Firstly, in terms of world - building, you need to find a way to make Hogwarts and the Jedi Academy (or equivalent Star Wars settings) coexist in a logical way. Secondly, the gay relationship has to be developed in a way that respects the characters from both universes. Harry Potter characters have their own personalities and story arcs, and so do the Star Wars characters. Combining them in a romantic or sexual relationship requires a great deal of creativity. Moreover, you have to consider the fan bases of both franchises. Some fans might be resistant to this kind of crossover and the addition of a gay relationship, so writing in a way that can appeal to a broader audience while still staying true to the concept is quite difficult.
One challenge is combining different universes. Kingsman has a modern, spy - based world, while Harry Potter is a magical boarding - school - based universe and Merlin is from a more mythological - historical setting. Keeping the rules and tones of each consistent while merging them can be tough. Another is pleasing fans of all three. Fans of each franchise have specific expectations, and it's hard to meet them all in one story.
Maintaining the integrity of both universes is a big challenge. Fans of 'Harry Potter' and 'Star Wars' are very protective of their respective franchises. A writer has to be careful not to distort the core concepts, themes, or lore of either. For example, the rules of the Force in 'Star Wars' are very specific, and the same goes for the magic in 'Harry Potter'. Any deviation from these established rules can make fans unhappy. Additionally, the pacing of the story needs to be right. Since both series have their own pacing styles, finding a middle ground that works for a crossover can be tricky.
One challenge is merging the magic systems. Harry Potter has a very detailed and rule - based magic system, while Soul Eater has its own unique concept of souls and weapons. Writers need to find a way to make these two coexist without it feeling forced.
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.
