"Chimera" is the 14th episode of the seventh season of Star Trek: Deep Space Nine, the 164th episode overall. Set in the 24th century, the series follows the adventures of the crew of the Starfleet-managed Bajoran space station Deep Space Nine. The later seasons of the series follow a war between the United Federation of Planets and an expansionist empire known as the Dominion, ruled by the shape-shifting Changelings. Deep Space Nine's security chief, Odo (played by René Auberjonois), is a Changeling who grew up ignorant of his people, and turned his back on them once he learned they were the Founders of the Dominion. In this episode, Odo meets another Changeling, Laas (played by J. G. Hertzler), who is also ignorant of the Founders and tries to persuade Odo to leave Deep Space Nine and travel the galaxy with him.

Laas tells Odo that although he does not support the Founders' agenda of conquest, he does not trust humanoids and just wishes to avoid them. Odo introduces Laas to the practice of "linking": physically joining their liquid bodies, a very fulfilling experience for Changelings. Laas guesses that Odo would have returned to join the Founders and experience their Great Link had he not fallen in love with Bajoran officer Kira Nerys. Laas attempts to convince Odo to embrace his potential as a Changeling rather than trying to blend in with humanoids, and behaves rudely and condescendingly toward Odo's humanoid friends. He suggests that Odo join him to travel the galaxy in order to find more of the Hundred and form their own Great Link. Odo is tempted, especially when Laas demonstrates his skill at shapeshifting into unusual forms. Laas causes a disturbance when he transforms into a fog in the station's Promenade district, drawing the attention of two Klingon officers. Seeing what they assume is a Founder, they confront Laas violently; by shapeshifting he is able to escape the
