What are some interesting plot ideas for Spider - Man Arkham Asylum fanfiction?

A crossover with the Justice League. Imagine if a mind - controlling villain took over Arkham Asylum and used the inmates as a weapon against the Justice League. The League would have to infiltrate the asylum, not only fighting the villains but also trying to break the mind control without harming the inmates too much.

One idea could be exploring Scarecrow's backstory in more depth. Maybe show his early days in Arkham Asylum, how he was treated by the staff and inmates, and what led him to become the terrifying Scarecrow. Another plot could involve Scarecrow creating a new and more powerful fear toxin that not only affects Batman but also the citizens of Gotham, and Batman has to race against time to find an antidote while dealing with his own fears.

Another plot could involve a crossover with a fantasy world. Imagine Batman being transported to a world like Middle - earth. He'd have to use his gadgets and combat skills in a world full of magic and mythical creatures. He might team up with characters like Aragorn or Legolas to fight against an evil force that has some similarities to the criminals in Arkham Asylum, perhaps a dark sorcerer who is as mad and unpredictable as the Joker.

One idea could be inserting yourself as a new inmate with a unique skill set, like being a master of disguise. You could use this to outwit the villains and even Batman at times. Another could be being a doctor who has a secret agenda and is using the chaos in Arkham to further their own ends. Maybe you're trying to steal some of the Joker's toxin for your own evil plan.

Perhaps a fanfiction where Poison Ivy falls ill due to some strange new chemical in Arkham Asylum. Batman, instead of seeing her as just a villain, decides to help her find a cure. This would lead to a journey through the asylum, facing other villains who might want to take advantage of Ivy's weakened state, and also a deeper exploration of Ivy's character and her connection to nature.

The Joker would be a great addition. His chaotic nature would contrast well with Spider - Man's quippy and more light - hearted style. Also, Two - Face. His duality could create some interesting moral dilemmas for Spider - Man. And of course, Poison Ivy. Her plant - based powers could make for some unique battles within the asylum's walls.

One idea could be exploring the different Spider - People's home universes in more detail. For example, showing what Miles Morales' daily life in his universe was like before becoming Spider - Man. Another could be a team - up between Miles and an older, more experienced Spider - Person from a different universe to face a new and powerful villain.

Perhaps there's a fanfiction where Spider Man and Spider Gwen accidentally swap powers. They have to learn how to use each other's abilities to fight crime. This would lead to some really funny and also challenging situations as they get used to different ways of web - slinging and sensing danger.

In this fanfiction, Naruto could be a patient in Arkham Asylum. He has lost his memory and believes he is in some strange version of Konoha. The doctors at the asylum are trying to understand his 'delusions' about ninjas and chakra. Meanwhile, some of the more evil inmates sense his power and try to manipulate him for their own gain.

One plot idea could be that Spider Man and Spider Woman team up to fight a new supervillain who has the power to manipulate time. They have to figure out how to work together while also dealing with the chaos the villain is causing in different timelines. Another could be a story where they get trapped in an alternate dimension and have to find a way back home while facing strange new enemies. Maybe there's a plot where they start to have feelings for each other but are afraid it will interfere with their superhero duties.
