Mirror Universe

The Mirror Universe is a fictional parallel reality appearing in science fiction, notably in "Star Trek." It presents a universe where the moral alignments and decisions of characters are often reversed or altered, leading to darker, more militaristic societies. In this universe, characters who are heroic or compassionate in the primary universe might be villains or oppressive rulers. The concept explores alternate outcomes of events and questions about morality, identity, and the nature of good versus evil by imagining how different choices could lead to entirely different worlds.
