Well, he might form alliances. For example, he could team up with someone like Magneto. They might use their powers together to take over a city or fight against a common enemy like the Avengers in that fanfic world. It would be a chaotic and interesting combination of powers and personalities.
Well, in the comics, there's no fixed number of Lokis. They keep popping up in different timelines and realities. It's all part of the fun and complexity of comic book storytelling.
One possibility is that they would have a contest of magic. Marvel Loki is known for his illusions and shape - shifting, but DC Loki might have some different magical abilities. They could show off their skills to each other, perhaps in a friendly sparring match at first. But then it could turn into a more serious competition as their egos get involved. DC Loki might try to prove that his magic is more powerful, while Marvel Loki would want to show off his superior trickery.
One possible scenario could be that Loki, in his mischievous ways, decides to play a prank on Peter Parker. Maybe he disguises himself as a normal citizen and lures Peter into a situation where he has to use his spider - sense and quick thinking to figure out Loki's true identity. This could lead to an interesting battle of wits between the two, with Loki's magic against Peter's acrobatic and web - slinging skills.
I think it could be Star - Lord. He's often looking for an edge in any situation, and Loki could offer some unique opportunities. They could form a sort of uneasy alliance where they both try to use each other for their own goals. Star - Lord might see Loki as a valuable asset in terms of his magic and knowledge of other worlds, while Loki could use Star - Lord's leadership skills and connections within the Guardians. However, they would constantly be on guard against each other's double - crosses.
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.
In a fanfiction where Loki meets Hela, their interaction would be complex. At first, Loki would be cautious, as he knows Hela's reputation. Hela would be dismissive of Loki, seeing him as a lesser being. But as they start to talk, Loki might share some of his experiences of being ostracized in Asgard. This could pique Hela's interest, as she herself was banished. They might start to exchange stories, and slowly a relationship of mutual understanding could develop. But it would always be a fragile relationship, with Hela's power and Loki's deviousness creating an undercurrent of unease.
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.
The plot could involve Loki's mischief and Wanda's powerful magic clashing or collaborating. Maybe Loki tries to trick Wanda at first, but she sees through his schemes with her mind - reading abilities. Then they could end up teaming up against a common enemy, like a powerful dark sorcerer threatening the multiverse.
