alter ego

The phrase "alter ego" refers to an alternate or secondary personality of an individual. It describes a separate and distinct persona that a person assumes or creates, often used as a way to express a different side or aspect of their character. The alter ego may embody different traits, behaviors, or beliefs compared to the person's usual self, allowing for self-expression or the exploration of different identities. It can also serve as a mask or disguise, enabling individuals to take on different roles or escape from their usual reality.
