John Wick could be brought into the Avengers' universe through a multiverse - type situation. Maybe a villain's experiment goes wrong and opens portals that pull in characters from different realities, including John Wick. Once there, he'd quickly assess the situation. Given his no - nonsense attitude, he'd probably start taking action against the common enemy right away, without waiting for the Avengers to fully understand his motives.
One possibility is that John Wick's combat skills would be a huge asset to the Avengers. He could teach them some of his unique hand - to - hand combat techniques. For example, his proficiency in close - quarters gunplay and his ability to use the environment to his advantage could be shared with the likes of Black Widow or Hawkeye. Maybe he'd get into a friendly competition with Captain America over who's the better fighter in a no - powers situation.
It could work by having a common enemy. For instance, a powerful crime syndicate that has ties to both the Avengers' world (like Hydra having some sort of deal with the syndicate) and John Wick's world. This would force them to collaborate.
Maybe in the fanfiction, the Avengers need someone with John Wick's particular set of skills for a stealth mission. John Wick initially refuses but is later convinced when he realizes the threat is global. During the mission, they learn from each other's combat styles and strategies, and John Wick's no - nonsense attitude impresses the Avengers.
Action sequences are a very popular element. Fans love to see how John Wick's unique combat style meshes with other characters in crossover fics. Another popular element is the exploration of different universes. For example, when he crosses into a science - fiction world, how he adapts to new technologies and rules.
Tony Stark, being the brash and confident one, might find the fanfiction a bit too simplistic compared to his high - tech world. He could say something like 'This John Wick guy needs some Iron Man tech to really up his game'. On the other hand, Thor would probably be in awe of John Wick's physical prowess and his ability to take on so many foes single - handedly.
Well, they might be impressed by John Wick's badassery in the fanfiction. Tony Stark would probably make some sarcastic comments about the action scenes. Thor might compare John Wick's combat skills to his own. And Natasha would be analyzing the stealth and strategy elements.
You could start by setting the scene where John Wick is in a situation that somehow intersects with the Avengers' world. Maybe he's on a mission in New York and stumbles upon one of their battles. Then, you can write about the initial reactions of both parties. For example, Thor might be confused by this mortal who is so skilled in combat. Then, as the story progresses, you can create a common enemy for them to fight together. It could be a new villain who is using both high - tech weapons and underworld connections, which is where John Wick's expertise comes in.
Sure. One great John Wick crossover fanfiction is the one where he crosses over with the world of 'The Matrix'. It's really exciting to see John Wick's combat skills in the high - tech world of The Matrix. Another interesting one is his crossover with the 'Die Hard' universe, imagining how he and John McClane would team up to take on bad guys.
They could start off with some misunderstandings. Izuku might accidentally get in John Wick's way, thinking he's helping. But as they get to know each other better, Izuku would start to learn from John Wick. John Wick could see Izuku as a young, eager protege of sorts and start to teach him things like how to handle different weapons and how to read his opponents better in a fight. They would gradually build a relationship based on mutual respect for each other's skills and values.
