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.
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.
Sure. There are John Wick comics available. These comics might delve into untold stories or provide alternate takes on events from the films, giving fans even more to enjoy in the John Wick universe.
A John Wick crossover with 'The Equalizer' could be really cool. They both have a sense of justice and a particular set of skills. They could team up to take on a powerful and corrupt organization. Maybe they start off as rivals, not trusting each other's methods, but as they face the common enemy, they learn to work together and combine their unique fighting styles.
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.
