Wonder Woman and Green Lantern (Jessica Cruz). Wonder Woman's combat skills and leadership, along with Jessica's power ring abilities, would be a great combination. They could face off against enemies that require both physical combat and constructs created by the power ring. They could also learn from each other's different ways of approaching challenges.
Supergirl and Bumblebee could be a great pairing. Supergirl's super strength and flight combined with Bumblebee's ability to shrink and fly as well could lead to some interesting scenarios. They could infiltrate small spaces together or Supergirl could carry Bumblebee to quickly reach far - off locations.
Batman and Robin is a classic pairing. It's not just a superhero - sidekick relationship but also has a deep emotional bond. Their crossovers often explore Robin's growth under Batman's tutelage and how they handle different threats together.
Spiderman and Green Lantern. Green Lantern's power ring can create all kinds of constructs, and Spiderman could use his webs to enhance or modify those constructs. They could work together to build a huge structure to stop a giant alien invasion that is threatening both the Marvel and DC universes.
Definitely Superman and Captain America. They both represent the ideals of their respective universes. Superman with his superhuman strength and unwavering moral compass, and Captain America with his leadership and never - give - up attitude. Another interesting pairing would be Batman and Iron Man. They're both brilliant inventors and strategists, and seeing them compete or collaborate on a project would be fascinating.
How about a crossover with the Gotham City Sirens? Harley Quinn, Poison Ivy, and Catwoman from that group could interact with the DC Superhero Girls. There could be a lot of fun and chaos as the girls try to either reform or fight against the Sirens. Maybe they end up having to work together when a bigger threat to Gotham emerges that affects both the good and the bad guys.
Definitely Wonder Woman. She's such an iconic character and in crossovers, she can bring her strength and wisdom. For example, if she crosses over with the Birds of Prey, she could lead the team in a fight against some new threat to the city.

I think Thor and Wonder Woman would make an amazing pair. They both come from god - like lineages. Thor with his Asgardian powers and Wonder Woman with her Amazonian and divine powers could have some epic battles together against common foes. Their different yet powerful fighting styles would complement each other well.
Gohan and Robin would be an interesting pairing. Gohan, with his intelligence and powerful fighting skills, could bond with Robin over their shared smarts and desire to protect their respective worlds. They could exchange knowledge about combat strategies and detective work.
Maeve and Wonder Woman could be an interesting pair. They are both strong female characters, but from very different backgrounds. Wonder Woman could show Maeve a more noble way of using her power, while Maeve could expose Wonder Woman to the harsher realities of the world she lives in.
Peter Parker and Lex Luthor could be a fascinating duo in a different way. Luthor might initially try to use Spider - Man's powers for his own gain, but Spider - Man outsmarts him. This could lead to a complex relationship where Luthor is constantly trying to manipulate Spider - Man, but Spider - Man is always one step ahead, all while they are in the middle of a bigger conflict involving other heroes and villains from both universes.
