A Koropian princess was mentioned in the script of the Star Trek: The Next Generation episode "Cost of Living".

In the scene, which did not make it in the final episode, Deanna Troi recalled how on her sixth birthday party, Lwaxana Troi disappeared halfway through the celebration, but returned later, dressed as a Koropian princess and carried in a sedan chair by four young men. She remembered being mortified, and remarked to Worf that all her life she had felt as if she was the parent, and Lwaxana the child.
