A third idea could be a battle royale between the Hulk and Doomsday. Maybe Darkseid is interested in seeing which of these two incredibly powerful beings is stronger. He transports the Hulk to Apokolips and sets up a fight between him and Doomsday. The fight could be epic, with the Hulk's brute strength and Doomsday's regenerative abilities making it a back - and - forth battle. Meanwhile, some of the heroes from the DC universe, like Wonder Woman and Green Lantern, are trying to figure out a way to stop the fight before it destroys Apokolips.
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.
One idea could be a crossover with Spider - Man. She - Hulk and Spider - Man team up to take on a new villain in New York. Maybe this villain has the ability to manipulate technology and is causing chaos in the city. Another plot could involve a crossover with Doctor Strange. She - Hulk accidentally gets caught in a magical spell and is transported to a different dimension. She has to work with Doctor Strange to find her way back home while also dealing with the threats in that dimension. A third plot could be a crossover with the X - Men. She - Hulk joins forces with the X - Men to protect mutants from a new anti - mutant group that is using dangerous new weapons.
A cool dc superheroes crossover fanfiction could involve Wonder Woman and Aquaman. They could discover an ancient underwater civilization that has a connection to the Amazons. As they explore this link, they face off against some sea - based villains and also have to deal with the political tensions between the surface world and Atlantis.
Another interesting concept is a crossover of Wonder Woman and Aquaman. They might come together when an ancient underwater and Amazonian artifact is stolen. The story could explore their different cultures as they travel across land and sea to retrieve the artifact and prevent it from being used for evil.
In a deku dc crossover fanfiction, perhaps Deku's quirk could be misinterpreted as a meta - human ability in the DC universe. The Justice League might initially be suspicious of him but then realize his pure heart and strong sense of justice. He could also share his knowledge of hero training and strategy with the younger heroes in the DC world like Robin.

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.
Maybe Deadpool could team up with Harley Quinn. Their personalities are both wild and unpredictable. They could go on a rampage through Gotham, with Deadpool constantly breaking the fourth wall and Harley just being her crazy self, driving the Batfamily nuts as they try to figure out how to deal with this odd couple.
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.
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.
