Together, they make a formidable team, using their respective skills to outwit their enemies.
In this fanfiction, Harry could be a target of the same organization that John Wick has a vendetta against. Harry, being unaware of the Muggle underworld's danger, is caught off - guard.

The main antagonist could be an ancient and evil entity that has been controlling the criminal underworld from the shadows for a long time.

So, it uses all its minions and resources to hunt down Harry, with John Wick standing as the last line of defense against this powerful and mysterious foe.

So, they have to put aside their differences and work together to keep the item out of the wrong hands. During their time together, they learn from each other's fighting styles and strategies.
Well, it might follow a female assassin in the same universe as John Wick. Maybe she has a personal vendetta against some powerful underworld figures, just like John Wick had his own reasons to seek revenge.

In this fanfiction, perhaps there's a crossover of their skills. Harry Potter could use his magic to enhance John Wick's weapons. For example, making his bullets have magical properties like tracking spells. John Wick could teach Harry Potter how to be more stealthy and efficient in combat without relying solely on magic. The story could be set in a post - Voldemort world where a new danger emerges, and they have to combine their strengths to save both the wizarding world and the normal world that John Wick comes from.
