Writers often start by finding a common ground between Tony Stark's world and the other universe they want to cross over with. For example, if it's a crossover with the LOTR universe, they might focus on the idea of Tony's technology in a world of magic. They then play with the characters' personalities. Tony's arrogance could clash or blend well with the characters in the other universe.
They use the contrast between Tony's high - tech world and the new universe. In a crossover with a historical - based universe like Ancient Rome, the difference in technology and culture is a great source of drama. Writers also give Tony new challenges in these crossovers. If he's in a world full of super - natural beings, he has to figure out how his suits and tech can deal with things like magic or other powers. They also create new relationships for Tony, which can be romantic or just strong friendships that change the dynamic of the story.
They play with the differences in the universes. Let's say a crossover with a post - apocalyptic world. Shirou's skills and values would be tested in a whole new way. The writer has to create new challenges for him, like how he would deal with limited resources while still trying to uphold his heroic nature. Also, they might introduce new characters from the crossover world that can either help or hinder Shirou, adding more depth to the story.
Writers can create unique plotlines by focusing on the zerg's adaptability. For example, if the zerg cross into a universe with magic, they could start to incorporate magical elements into their biology. This would lead to a plot where the characters in the original universe have to figure out how to deal with this new, magically - enhanced zerg threat.
Writers often combine the iconic settings from each slasher's original story. For example, if it's a crossover between 'Friday the 13th' and 'A Nightmare on Elm Street', they might merge Camp Crystal Lake and Elm Street. This creates a new and unique space that fans of both can recognize and get excited about.
One popular type is the Tony Stark and Sherlock Holmes crossover. In these fanfictions, Tony's genius inventor skills meet Sherlock's deductive reasoning. Another is the crossover with the Harry Potter universe, where Tony might bring his high - tech gadgets to Hogwarts. There are also crossovers with the DC universe, often pitting Tony against Batman in a battle of wits and technology.
Another way is to change the rules slightly. In a Tokyo Ghoul and My Hero Academia crossover, the writer could say that in this new world, some people have both quirks and ghoul powers. This forces the characters to adapt and creates a whole new dynamic. They also introduce new conflicts. Maybe the heroes think all ghouls are villains at first, but then they discover some are just trying to survive. This helps in building a unique world full of tension and new relationships.
Writers often start by identifying the key elements of both the Walking Dead Games and the other franchise they are crossing over with. They look at things like the setting, the characters' personalities, and the overall themes. For example, if it's a crossover with a fantasy game, they might combine the post - apocalyptic setting of The Walking Dead Games with magical elements from the fantasy world.
They often combine different traits from existing Naruto characters. For example, a new character might have Naruto's determination and Sasuke's cool - headedness. Or they give the character a unique power that is not in the original series, like the ability to manipulate light in various forms. Also, they might create a character with a strange backstory, such as being raised by a mythical creature in the Naruto world.
They create unique storylines by mixing different elements from the Naruto world. Maybe they combine a forgotten ninja art with a modern - day problem in the shinobi world. Writers also like to give Naruto new goals that are different from what he had in the original series. This could be something like trying to reform the entire ninja education system. They also add new characters that bring fresh conflicts and relationships into the story.
Some writers depict their relationship as a power struggle. Tony, with his technological prowess, and the Enchantress, with her magic, are constantly vying for dominance. For example, in a lot of fics, they start off as enemies, each trying to outwit the other.
One way this could work is if there was a shared enemy. Let's say a powerful being that threatened both the wizarding world and the world of the Avengers. In order to combat this threat, a magical - technological alliance was formed. During this alliance, Tony Stark and a powerful witch (Hermione's mother) got close, and Hermione was born. This would create a really interesting dynamic in the fanfiction, with Hermione having the intelligence of her father and the magical abilities from her mother's side.
