What are some interesting plot ideas for a Spiderman and DC crossover fanfic?

Maybe in this fanfic, there's a multiverse crisis that causes parts of New York in the Marvel universe to merge with Gotham in the DC universe. Spiderman and Superman meet and initially have a bit of a misunderstanding due to their different ways of handling things. But then they realize they need to work together to separate the two cities again. Spiderman could use his webs to help Superman contain some of the chaos while Superman uses his strength to move large structures that are in the way.

One idea could be that Spider - Man gets transported to the DC universe through some sort of interdimensional rift. He teams up with Batman to stop a new villain who has the powers of both Green Goblin and the Joker. Their combined detective skills and combat abilities would make for an exciting story.

A cool plot could involve Wonder Woman, Flash, and Aquaman. They find themselves in an alternate dimension where the rules of their powers are all mixed up. Flash might not be as fast, Aquaman can't communicate with sea creatures as well, and Wonder Woman's lasso doesn't work as expected. They have to figure out how to adapt and work together to get back to their own dimension while also facing the threats in this new world.

One idea could be a Spiderman and Iron Man crossover. Spiderman could team up with Iron Man to fight a new, powerful villain. Maybe they have to combine their tech and skills, like Spiderman using his web - slinging abilities along with Iron Man's high - tech gadgets to take on an enemy who can manipulate electricity.

One plot idea could be Spiderman getting transported to the DC universe and forming a harem of female superheroes who are initially skeptical of him but gradually come to respect and love him as they fight together against common threats. For example, he could team up with Wonder Woman, Batgirl, and Supergirl.

One idea could be that Spider - Man gets accidentally transported to the DC universe. He teams up with Batman to take on a common enemy like the Joker who has somehow gotten his hands on some Oscorp tech. They combine their detective skills and combat abilities to stop the chaos.

One idea could be Ahsoka getting transported to the DC universe and teaming up with Batman. She could use her combat skills and Force - sensitivity to help him fight against Gotham's villains. Another plot could involve her meeting Wonder Woman and learning about the different types of power and heroism in the DC world. Maybe she gets caught in the middle of a battle between the Justice League and their enemies and has to use her Jedi wisdom to broker peace.

One idea could be that Spider - Man gets accidentally transported to the DC universe. He teams up with Batman to take on a new villain that is a combination of their rogues' galleries. For example, a villain who has the powers of Electro and can also control minds like Brainiac.

One idea could be a story where the Avengers and the Justice League team up to fight a common enemy like Darkseid and Thanos working together. Another could be a character - swap scenario, for example, Superman being in the Marvel universe and having to deal with the likes of Doctor Doom. Maybe a story where Batman uses his detective skills to solve a mystery in the Marvel world that involves Hydra.

How about a crossover with the Hulk? Spiderman might be on a mission in a city when the Hulk goes on a rampage. Instead of fighting the Hulk directly, Spiderman has to figure out a way to calm him down or lead him away from the populated areas. Along the way, they could encounter some other villains who are trying to take advantage of the situation, and then they end up teaming up to defeat the villains.
