A cool scenario would be a battle royale - style crossover where Wonder Woman is brought into the Marvel universe to participate in a tournament. She has to fight against various Marvel heroes and villains, like Thor and Loki. As she progresses, she discovers that the real mastermind behind the tournament is trying to use the chaos to open a portal to another dimension. Along the way, she forms alliances with some of the Marvel characters and together they try to stop the evil plan.
Wonder Woman is from DC. DC has crafted a rich and detailed mythology around her, and she's a key figure in their comic book universe. Her powers, backstory, and adventures are all part of the DC Comics lore.
The plot could involve Wonder Woman's bracelets being a key to an ancient power source that exists in the Marvel universe. She travels there to find it and protect it from falling into the wrong hands. Along the way, she meets Iron Man. Iron Man is initially intrigued by her technology and they have a bit of a clash as he tries to study her bracelets. But when the real threat emerges, they team up.
