Cassiopeia Psyche (Mirror Universe, Empath stories)

Cassiopeia is a Psyche character who exists in the Mirror Universe version of Psychelia in the EMPATH: The Luckiest Smurf story series. She is a student who is the partner and life mate of Polaris Psyche, who often encourages him to explore his abilities to the utmost and shares his desires to someday leave Psychelia so that they could explore the world together, despite the Psyche Master's warnings that the world is a dangerous place for beings like Psyches. She helped restore the normal universe Polaris Psyche back to health when he arrived in Psychelia and was present with him when he sought aid from the Psyche Master to help defeat the Mirror Universe Smurfs.

It is most likely that Cassiopeia's normal universe counterpart is still in Psychelia serving the will of the Psyche and bonded to a same-sex partner.
