One way it could work is if there was a time - travel or multiverse plot. For instance, Arrow characters could accidentally end up in Riverdale's time period or vice versa. They would then have to figure out how to get back while dealing with the local problems. Maybe Green Arrow has to help solve a mystery in Riverdale that's related to his own enemies in some way.
In a Riverdale and Arrow crossover fanfiction, it could work through a character connection. What if Oliver Queen has a long - lost relative in Riverdale? He goes there to find out more about his family history. At the same time, there are strange happenings in Riverdale that seem related to the criminal underworld that Oliver is used to fighting. He teams up with the Riverdale characters, who are initially skeptical of him but soon realize his skills are useful. They would all have to navigate the different social dynamics of each other's worlds, with Oliver trying to fit into the high - school - ish environment of Riverdale while the Riverdale kids are exposed to the more dangerous world of Arrow.
A possible way for this crossover fanfiction to work is by having a common threat that affects both Riverdale and Star City. Let's say a new criminal organization is using Riverdale as a base to develop some sort of super - weapon. Arrow's team hears about it and comes to investigate. They meet the Riverdale gang, and together they try to take down the bad guys. The Riverdale kids could use their knowledge of the town and its secrets, while Arrow's crew brings their combat and high - tech skills.
In a Riverdale and Arrow crossover fanfiction, the story could start with some sort of interdimensional rift that pulls characters from both shows into one world. Riverdale characters would be shocked by the violence and danger in Arrow's world. Meanwhile, Arrow characters might find the high school drama and relationships in Riverdale quite strange. There could be a big bad villain that only the combined skills of both groups can defeat. They would have to learn to work together despite their differences, and along the way, there could be some romantic subplots between characters from the two shows as well.
Arrow is a hero who has grown from a playboy to a more serious protector of Star City. He has a sense of humor that is a bit darker and more sarcastic. Batman, while also having a dark side, is more stoic. Their different personalities could create some humorous moments in a crossover. For instance, Arrow might make a sarcastic comment about Batman's overly - serious approach, which could break the tension in a difficult situation. And while they might seem at odds initially because of their different ways of handling things, they would eventually realize that their combined efforts, with their unique personalities, are what will be needed to save the day.
Spider - Man's spider - sense could be a great asset when combined with Arrow's combat skills. The spider - sense could alert them both to incoming danger, allowing Arrow to prepare his next shot while Spider - Man positions himself for an attack. Also, Spider - Man's strength could be used to carry Arrow to higher vantage points for better shooting positions, or to quickly move him out of harm's way during a battle.
In the fanfiction, their teamwork could be shown as a bit chaotic at first. Each hero has their own way of doing things. Arrow is more stealthy and methodical, Flash is impulsive and fast - acting, and Supergirl is more of a straightforward hero. But when they face a really tough enemy, they realize they need to combine their approaches. So Arrow might come up with a plan that incorporates Flash's speed for a quick execution and Supergirl's strength to overpower the enemy's defenses. They would have to communicate constantly and adjust their teamwork as the situation changes.
In a crossover, Archie's relationship with his friends might change. He's used to being the football star in Riverdale, but in the Arrowverse, he could be in awe of the superheroes. His friendship with Jughead might be tested as Jughead tries to keep Archie grounded while Archie is excited about the new world. Betty and Veronica's relationship could also shift. They might compete in a different way, like trying to impress a certain Arrowverse hero. Their friendship could become more competitive or they could find new common ground in helping the heroes.
In a Stranger Things and Riverdale crossover fanfiction, there are so many possibilities. The gangs from both shows could team up against a common enemy. Let's say a new evil entity that combines the characteristics of the Demogorgon and the Black Hood. The friendships and romances in the story could be completely reshuffled. Steve might have a fling with one of the Riverdale girls, or Nancy could become friends with Betty. And the settings could blend together, with scenes taking place in both Hawkins and Riverdale, creating a really engaging and unique story.
Well, Archie might befriend Harry Potter. They both have a sense of justice and are brave. Archie could introduce Harry to football (or soccer as it's known in some parts of the world), and Harry could show Archie how to play Quidditch. Betty and Hermione could bond over their intelligence and love for books. They might study together in the Hogwarts library.
In a Zootopia - Outlander crossover fanfiction, the settings would play an important role. The bustling cityscape of Zootopia with its different districts for different species could be contrasted with the rustic and often dangerous landscapes in Outlander. The characters could travel between these settings, bringing a sense of adventure. For example, the Zootopia police could be chasing a criminal who has escaped into the Outlander world. This would lead to a series of exciting chases and encounters, as the Zootopia characters have to adapt to the new environment while trying to catch the bad guy.
Well, it could start with a portal opening between the two worlds. Then characters from both sides start to interact. The Naruto characters would be shocked by the Needless' powers, like their extreme physical abilities and unique powers. And the Needless might be intrigued by the chakra system in the Naruto world.
Daredevil is a master of hand - to - hand combat. His skills in martial arts would be a great asset when they are in close quarters. Arrow, on the other hand, has his archery skills which are excellent for taking out enemies from a distance. When combined, they can create a very effective fighting style. For example, Daredevil could engage the enemies up close, and Arrow could pick off any reinforcements or threats from afar. Daredevil's radar - sense can also help Arrow aim better in situations where visibility is low, like in a dark alley or a smoky building.
