What are some interesting storylines in Justice League fanfics for adults?

A third interesting storyline might involve a secret alliance between a member of the Justice League and a villain that the Young Justice team discovers. This discovery then sets off a chain of events where the Young Justice team has to decide whether to trust the rest of the Justice League and how to handle this new information without causing a complete breakdown in the superhero community.

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 Wolverine being brought into the Justice League's universe due to a multiverse rift. He might initially clash with some members like Batman over their different approaches to justice. Batman is all about strategy and preparation, while Wolverine is more of a brawler. But over time, they learn to work together and Wolverine's healing factor and combat skills prove invaluable against a powerful new threat that the Justice League alone couldn't handle.

There could be a story where an OC has the power of telepathy but is initially shunned by the Justice League because they're afraid of this new power. The OC then has to go through a journey of self - discovery and also convince the League that they can be an asset, perhaps by using their power to stop an alien invasion that was hidden from the League's normal detection methods.

One interesting storyline could be the Powerpuff Girls teaming up with the Justice League to fight a common, super - powerful enemy from outer space. The Powerpuff Girls' unique powers and small - but - mighty nature could add a new dynamic to the Justice League's battles.

One interesting storyline could be the Justice League having to deal with a mind - controlled Batman. Maybe some villain manages to take over Batman's mind, and the League has to figure out how to stop him without harming their friend. It would be full of action as they try to outwit Batman's strategic plans while also trying to break the mind control.

Another storyline might involve a character from the X - Men, say Wolverine, getting transported to the Justice League's universe and having to adapt. He could bring his no - nonsense attitude and combat skills, and in the process, learn about the different threats and heroes in that universe. For example, he might have a run - in with Batman and learn about his detective skills.

Well, a possible storyline is that Kara (Supergirl) teams up with Naruto to rescue hostages taken by a group of rogue ninjas and super - villains. They use their respective powers - Naruto's shadow clones and Kara's super strength and flight - to outwit the bad guys. Also, there could be a plot where the Justice League and the Naruto characters have to figure out how to work together despite their very different combat styles.

Another idea is that the Justice League is invited to Wakanda for a cultural exchange. However, things go wrong when an ancient Wakandan curse is accidentally awakened. This curse starts to affect the powers of the Justice League members. Black Panther, being familiar with the history and magic of his homeland, has to lead the way in finding a solution. They might have to explore hidden parts of Wakanda, face mythical creatures, and use both Wakandan and Justice League technology and powers to break the curse.

A third possible storyline could be a story of misunderstanding at first. The two groups could initially see each other as threats. For instance, the Justice League might mistake the Z - fighters' high power levels as a sign of aggression. However, through a series of events and battles, they come to realize that they are on the same side and must work together to face greater threats. This could involve some epic one - on - one battles between characters like Vegeta and Superman before they finally team up.
