One idea could be a story where Oliver Queen finds himself in Kara's universe by some sort of multiverse accident. He teams up with Kara to fight a common enemy that is causing chaos in both their worlds. Their different fighting styles, Oliver's more grounded archery and hand - to - hand combat and Kara's super - powered abilities, would make for an interesting dynamic in battles.
A good plot could be that Oliver is framed for a crime he didn't commit in Kara's world. Kara, believing in his innocence, decides to help him clear his name. As they dig deeper into the conspiracy, they discover that there is a powerful villain behind it all who wants to destroy both their reputations. They have to use their combined skills, Oliver's detective skills and Kara's super - senses, to expose the truth.
Alex Danvers should be in it. As Kara's sister, she would be very protective and could have some interesting interactions with Oliver. She could also offer her military and strategic skills to the team, and her presence would add more depth to the story as it shows Kara's family dynamic.
One interesting plotline could be Oliver and Kara teaming up to fight a powerful, new villain that neither of their respective cities have faced before. They combine their unique powers and skills to take on this threat.
One common theme is the exploration of their different powers and how they complement each other. For example, Oliver's combat skills and Kara's superpowers can be combined in unique ways in the stories.
