Perhaps the plot could start with Loki causing chaos in New York City, just like he did in the Avengers movie. But this time, Doctor Strange steps in. Instead of fighting right away, Strange tries to reason with Loki. Loki is intrigued by Strange's different approach. They then start to explore each other's powers and motives. As they do so, they uncover a conspiracy in the magical realm that involves both Asgardian and Earth magic. To solve this mystery and stop the impending doom, they must put aside their differences and work together, which is not easy given Loki's track record of deception.
One possibility is that Loki would be intrigued by Doctor Strange's magic. He might see Strange as a worthy opponent or even a potential ally in his schemes. Doctor Strange, on the other hand, would be cautious of Loki's motives. They could engage in a series of mind games, with Strange trying to outwit Loki's illusions and Loki trying to manipulate Strange into doing his bidding.
In this fanfiction, perhaps there is a mystery that spans different dimensions. Doctor Strange is familiar with the multiverse and different planes of existence, while Sherlock is an expert in solving mysteries in his own world. A series of disappearances start to occur, and the victims seem to be vanishing into thin air. Strange realizes that it has something to do with a portal between dimensions that has been misused. He teams up with Sherlock, who uses his sharp mind to figure out the pattern of the disappearances. Together, they close the portal and rescue the victims.
It could be a powerful sorcerer who has turned to the dark side. This sorcerer might be using his magic to manipulate events in Sherlock's world for his own gain. He could be creating illusions and false trails to throw Sherlock off, while also using his magic to fight against Doctor Strange.
A possible plot could involve a new, powerful dark sorcerer who has found a way to combine magic from both universes to become invincible. Doctor Strange tries to stop him but is quickly overpowered. Meanwhile, Harry Potter senses the danger through his connection to magic. He travels to Doctor Strange's side. Harry uses his knowledge of magical creatures from the Forbidden Forest. He summons a group of Centaurs who help him in the battle. With their combined strength and Harry's strategic use of spells like the Stunning Spell, they are able to defeat the dark sorcerer and save Doctor Strange.
Perhaps Doctor Strange would initially clash with some of the Avengers due to his different way of doing things. For example, Tony Stark might be skeptical about Strange's magic at first. But then they would realize they need to work together. Strange could use his time - bending magic to give the Avengers an edge in a fight against an enemy that can manipulate time too. He could also use his magic to heal some of the Avengers' injuries during the fight.
Definitely Doctor Strange and Loki. Loki is a master of trickery and Doctor Strange is a master of magic. Their interactions would be full of mind games and magic duels. Loki might try to deceive Strange, but Strange would see through his illusions with his magic.
Peter is young and often impulsive. He acts on his instincts quickly. Doctor Strange, on the other hand, is more calculated and methodical in his use of magic. Their personalities could clash when Peter jumps into a situation without thinking, and Strange has to clean up the mess. For instance, if Peter rushes into a magically - trapped area, Strange might have to use his magic to save him and then scold him for being reckless.
Well, in a Loki meets Hela fanfiction, it might start with Loki being forced to meet Hela in Helheim. He could be there on a mission for Thor or Odin. Hela might be intrigued by Loki's presence. She could offer him a deal - his freedom in exchange for helping her gain access to Asgard again. Loki would have to weigh the options and decide if he can trust Hela or if he's just walking into another one of her traps.
One possible plot is that Peter is exploring some strange part of the city, perhaps an alleyway that has some sort of magical anomaly. Loki, who is also drawn to the magic, appears. Peter is initially scared but then realizes Loki might not be there to cause trouble right away. They could end up teaming up to solve the mystery of the strange magic, with Loki teaching Peter some things about magic along the way.
In a 'loki meets tom fanfiction', perhaps Tom is a scientist who is researching interdimensional portals. Loki, being a master of magic and often traversing different realms, gets caught in one of Tom's experiments. At first, Loki is angry and tries to use his powers against Tom. However, Tom is able to convince Loki that he can help him get back to Asgard. Along the way, they learn from each other. Tom learns about the magic and wonders of Asgard, while Loki discovers the scientific knowledge of Earth and how it can be applied in his own world.
