Who would be the most interesting villain in a batman and spiderman crossover fanfic?

The Joker would be really interesting. Imagine him getting his hands on some of Oscorp's dangerous technology. He could use it to create chaos in both Gotham and New York in ways that neither Batman nor Spiderman have seen before. His unpredictable nature would make it hard for the two heroes to anticipate his moves.

The Reverse - Flash would be really interesting. He could target both Batman and the Flash. For the Flash, he's a long - time nemesis, but for Batman, he'd be a new and extremely dangerous threat. His ability to manipulate the speed force and time could put Gotham in chaos in ways Batman has never seen before. And he could use his knowledge of the Flash to try and set traps for both heroes.

The Joker would be really interesting. Imagine Deadpool meeting the Joker. Deadpool would be both fascinated and repelled by the Joker's insanity. The Joker, on the other hand, would be intrigued by Deadpool's indestructibility and chaotic nature. It would create a really wild dynamic, with Batman caught in the middle trying to stop both of them from causing too much mayhem.

Ra's al Ghul would be a great choice. He has ties to both the Arrow universe and Batman's world. He could be manipulating events in both Star City and Gotham, forcing Arrow and Batman to team up to stop his grand scheme. His immortality and vast resources would pose a huge challenge for them.

Ra's al Ghul would be a fascinating villain in a crossover. He has a global view of crime and destruction, and his Lazarus Pit gives him a certain immortality. His plans could involve both Hell's Kitchen and Gotham in some grand scheme. Daredevil would be out of his depth dealing with Ra's al Ghul's long - term, world - changing plans, and Batman would have to bring Daredevil up to speed while also trying to stop Ra's al Ghul's latest plot.

It's hard to say who is the most powerful. Batman has his intelligence, wealth, and gadgets. He can use his detective skills to outwit opponents. However, Spiderman has superhuman strength, speed, and his spider - sense. In a one - on - one fight, if Batman doesn't have time to prepare his gadgets, Spiderman might have the upper hand with his physical abilities.

How about a plot where the Joker teams up with one of Spider - Man's villains, say, the Green Goblin? They plan to create a new type of toxin that can drive people insane and also give them super - strength. The toxin starts to spread in both Gotham and New York. Batman and Spider - Man start to investigate separately at first. But as they realize the connection between the two villains and their plan, they join forces. Batman uses his intellect to analyze the toxin and find an antidote, while Spider - Man uses his speed and webs to stop the villains from spreading more of it. In the end, they manage to save both cities and put the villains behind bars.

Definitely Spider - Man and Iron Man. Their interactions would be super interesting because Iron Man is this high - tech genius and Spider - Man is a young, street - level hero with his own unique set of skills. Iron Man could mentor Spider - Man, upgrade his suit, and there could be some fun banter between them about science and superheroing. For example, Iron Man might be impressed by Spider - Man's homemade suit but also tease him about its limitations compared to his own high - tech creations.

It could be the Joker. Imagine the Joker getting involved in a global scheme and teaming up with some international bad guys. His chaotic nature would be a huge challenge for both Batman and the Totally Spies. He would use his usual tricks like laughing gas and mind games, but on a much larger scale.

Darkseid is another option. His power and his desire to conquer Earth could bring Batman and Superman together. He could target both Metropolis and Gotham, and his presence would require the two heroes to combine their skills. Batman's strategic mind and Superman's brute strength would be needed to face this powerful foe.
