How does the 'multiverse' aspect of the DC Cosmology impact the likelihood of hero/villain team-ups and conflicts across different realities?

The multiverse allows for hero and villain team-ups and conflicts across different realities. Characters from different Earths can interact, forming alliances or engaging in battles that transcend reality boundaries. This introduces unique dynamics and challenges for both heroes and villains, forcing them to adapt to unfamiliar environments and personalities. These multiversal conflicts often highlight the interconnectedness of all realities.
