Well, a common theme is the power of teamwork. Imagine Ok Ko characters and Nick Army characters having to work together to overcome a powerful villain. This shows how different skills from both groups can combine to achieve a goal. And then there's the theme of cultural exchange. Since they are from different fictional universes, there can be stories about how they learn about each other's cultures, like different fighting styles in Nick Army and unique technologies in Ok Ko.
One of the popular themes is rivalry - turned - friendship. At first, the Ok Ko characters and Nick Army characters might see each other as rivals, maybe competing for resources or recognition. But as the story progresses, they realize they have more in common than they thought and become friends. Another theme could be redemption. A character who has made mistakes in one of the universes could find a chance to redeem themselves through interactions with characters from the other universe.
