"The Chase" is the 146th episode of the science fiction television series Star Trek: The Next Generation. In this episode, four competing expeditions -- Federation, Klingon, Cardassian, and Romulan -- attempt to solve a genetic puzzle that proves to be the key to why Star Trek's version of the galaxy contains so many humanoid life forms. They are similar in appearance to the "generic humanoid" form taken by Odo and his shape shifting race from Star Trek: Deep Space Nine.
