One interesting storyline could be Thor finding out that his soul mate is an unexpected Avenger, like Bruce Banner. Their relationship could be about Thor helping Banner control the Hulk, and in the process, they discover a deeper connection.
In some fanfictions, Thor's soul mate among the Avengers could be Natasha Romanoff. Their story might involve Natasha using her spy skills to help Thor on a mission in Asgard. Along the way, they start to feel a pull towards each other that they can't explain at first. As they spend more time together, they realize they are soul mates and have to decide how their relationship will work between Asgard and Earth.
Maybe a story where Thor's Asgardian nature clashes with the more down - to - earth Avengers who are his soul mates. For example, Thor has different values when it comes to honor and combat compared to Steve Rogers. They have to work through these differences to truly embrace their soul mate bond. This could involve a series of adventures where they learn about each other's worlds.
It could be Tony Stark. Their personalities are quite different. Thor is more of a traditional hero with a noble background, while Tony is a genius billionaire playboy. But their differences could attract them to each other. They could bond over their shared love of protecting the Earth, just in different ways.
Yes, it can be quite popular. There are many fans of both Bella (presumably from Twilight) and the Avengers who enjoy exploring the concept of soul mates in fanfiction. It combines two very large fandoms, which often attracts a lot of readers interested in seeing how the different characters and universes interact in a new and creative way.
Often, you'll see a plotline where Bella has some hidden power or ability that only becomes apparent when she meets the Avengers. This then cements the idea of them being soul mates. There are also plotlines where Bella is in danger, and the Avengers feel a strong urge to protect her because of the soul mate connection. And sometimes, it's about Bella helping the Avengers deal with their own personal issues because of this special bond.
A cool story could be about them having a friendly competition to see who can solve a series of mysterious crimes in the other's city first. Along the way, they learn more about each other's methods and develop a deeper respect for one another. This also gives an opportunity to explore the different atmospheres and challenges of Gotham and Metropolis.
There might be a fanfiction where Jane discovers a new Asgardian relic that has a special connection to Thor. This could lead to a series of adventures as they try to figure out the relic's purpose together. They might face challenges from other Asgardians who think the relic should be kept hidden or used in a different way. It could also test their relationship as they deal with the different opinions and pressures.
One interesting story could be about Thor and Loki having to team up against a new, powerful enemy that neither of them can face alone. This forces them to put aside their differences and use their combined powers and wits to save Asgard.
One interesting storyline could be Thor joining the Justice League during a major threat from a powerful cosmic entity. His godly powers, like his lightning and strength, would add a new dynamic to the team's battles. For example, he could team up with Superman to take on an enemy that can manipulate gravity. Their combined strength and different power sets would make for an epic showdown.
One interesting storyline could be the students at Avengers University having to compete in a series of super - powered challenges. They might have to use their unique abilities, whether it's super strength, telepathy or the ability to fly, to overcome various obstacles. This would not only test their skills but also their teamwork and strategic thinking.
One interesting storyline could be the Avengers having to deal with threats on the homefront that are more personal and civilian - based. For example, they might have to protect a small town from a new type of villain who targets local infrastructure. Another could be the Avengers trying to integrate into normal life while still being superheroes, like Steve Rogers getting a regular job in addition to his superhero duties.
A lot of fanfiction focuses on Loki's redemption arc within the context of the Avengers. For example, Loki could be injured and the Avengers take him in instead of imprisoning him. This leads to him slowly seeing the value in their cause and starting to change his ways. He might start using his powers for good, like helping Thor understand some new magical threats, which also helps to strengthen the bond between him and the Avengers.
