What are some interesting ideas for a Deadpool crossover DC fanfiction?

Another idea is a crossover where Deadpool is hired by Lex Luthor to take down Superman. But of course, Deadpool being Deadpool, he ends up befriending Superman instead. He could constantly annoy Superman with his non - stop chatter and crazy stunts, but also help him in unexpected ways, like using his regenerative abilities to protect civilians during a big battle.

One idea could be Deadpool trying to join the Avengers in his own wacky way. He might show up unannounced at the Avengers Tower, causing chaos and confusion among the team members. Another plot could involve Deadpool being hired by a villain to disrupt the Avengers, but then he has a change of heart halfway through. Or perhaps Deadpool accidentally travels to an alternate universe where the Avengers are very different, and he has to find a way to get back while also dealing with this strange new team.

One idea could be Deadpool getting dropped into the RWBY universe and thinking it's some sort of crazy new mission. He starts trying to team up with the RWBY girls, but his chaotic nature constantly causes misunderstandings. For example, he might mistake a Grimm for one of his usual foes and go after it in his own wacky way, much to the confusion of the RWBY characters.

A cool dc marvel crossover fanfiction might involve Batman and Iron Man. Picture Batman being intrigued by Iron Man's high - tech gadgets and the two of them collaborating to create an even more advanced piece of technology to defeat a new breed of super - criminals that are using alien and advanced Earth - based tech.

One idea could be a plot where the Avengers and DC heroes are brought together by a powerful cosmic entity that threatens both universes. They have to combine their powers and strategies to defeat it. For example, Superman and Thor could work together to take on the entity's brute strength while Batman and Iron Man figure out its weaknesses using their intellect.

Well, in an 'ichigo and dc crossover fanfiction', perhaps Ichigo's Hollow powers could be mistaken for some kind of new meta - human ability in the DC universe. The Justice League might initially view him as a threat and try to contain him. But then, when they realize he's there to fight a greater evil, like Darkseid who has somehow tapped into the spiritual energy of Ichigo's world, they join forces. Ichigo could also share his knowledge of the afterlife with characters like Constantine, which could lead to some really interesting storylines.

One idea could be that the Hulk somehow gets transported to the DC universe. Maybe due to a freak accident involving some sort of interdimensional portal created by Lex Luthor in an attempt to bring in a powerful being to defeat Superman. The Hulk then starts rampaging through Metropolis, and Superman has to figure out how to stop him without causing too much destruction himself. He tries to reason with the Hulk at first, but when that doesn't work, he has to use his strength and speed to keep the Hulk occupied until they can find a way to send him back to his own universe.

A cool concept could be that Vegeta gets transported to Gotham City. He initially clashes with Batman due to their different methods, but they eventually work together to take down a powerful new enemy that is a threat to both their worlds.

One idea could be a story where the Avengers and the Justice League team up to fight a common cosmic threat like Darkseid and Thanos working together. It would be a battle of epic proportions with heroes from both universes having to put aside their differences and combine their powers.

One idea could be Master Chief getting transported to the DC universe and teaming up with Batman. They could combine their combat skills and strategic thinking to take on a common enemy like Darkseid.
