Fanfiction about Batman Arkham Asylum Crossover: What are some interesting plot ideas?

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.

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.

A more complex fanfiction could involve all of Team RWBY in Arkham Asylum. Blake could use her stealth skills to move around unnoticed, Yang's strength would be useful in physical confrontations. They could be there because some powerful enemy has lured them there, thinking it's a place where they'll be weakened. But together with Batman and some of the inmates who might side with them (like Harley Quinn who has a complex sense of morality), they could turn the tables on the enemy.

One idea could be that Naruto is somehow transported to Arkham Asylum. He might initially be confused by the strange new world, but his ninja skills could come in handy. For example, he could use his speed and agility to avoid the traps and villains in the asylum. Maybe he teams up with Batman, who is intrigued by Naruto's unique abilities.

Well, a great plot for Spider - Man Arkham Asylum fanfiction could be that the Green Goblin somehow gets locked in Arkham. Spider - Man follows him there to finish their feud once and for all. But when he arrives, he discovers that the asylum's strange atmosphere is affecting his powers in unexpected ways. He has to rely on his wits and some newfound allies among Arkham's inmates to defeat the Goblin and escape. This would create a lot of interesting scenarios as Spider - Man tries to navigate the dangerous and unpredictable world of Arkham Asylum.

A really interesting plot twist could be that the Grimm from RWBY are somehow connected to the madness in Arkham Asylum. Maybe they are being summoned by one of the inmates who has some sort of dark magic. Another plot twist could be that a character from RWBY, like Yang, turns out to be related to one of the Arkham Asylum staff in a very unexpected way.

One idea could be exploring the backstories of the lesser - known characters in the 'Batman Assault on Arkham' universe more deeply. For example, you could focus on Killer Croc's life before Arkham and what led him to become the way he is. Another plot could involve a team - up between unexpected characters from the movie, like Harley Quinn and Deadshot, against a new threat in Arkham that the Bat - family is unaware of.

One idea could be a story where Batman and Catwoman team up to take on a new, more powerful villain in Arkham. Maybe this villain has the ability to control the minds of the inmates, creating chaos. They'd have to use their unique skills, Batman's detective work and combat abilities, and Catwoman's agility and thieving expertise to stop the threat.
