to teach the infant shapeshifting abilities. However the infant is dying due to radiation poisoning; it "joins" with Odo so that he can regain his shapeshifting powers. ("The Begotten") Laas. Over 200 years old he ended up on the Valara planet where the name "Laas" means "changeable"; he left when he realized that he was only being tolerated and would never be accepted. He ended up on Deep Space Nine. He killed a Klingon in self-defense who was going to assault him and with the help of Major Kira he escaped. He vows to search the Alpha Quadrant in order to find the other missing "Hundred Changelings" like himself in order to create a new Great Link. ("Chimera") Odo. Quite young at 50 for a Changeling, he becomes Security Chief at Deep Space Nine. In a battle with a Changeling spy, Odo ended up killing him and thus breaking the most important rule of the Changelings (no Changeling must ever hurt another). He was punished by being changed by the Great Link into becoming a "solid". He regained his powers in the process of trying to save a dying Changeling. Although his deepest desire is to rejoin the Great Link, he is reluctant to do so due to the mad crusade of the "Female Changeling/Founder" for total war against every solid in the Alpha Quadrant. In the last episode, Odo rejoins the Great Link, saving them from being totally destroyed. ("What You Leave Behind") Mirror Universe In the Mirror Universe, Odo is the supervisor of the mining complex at Terok Nor. He is a brutal taskmaster over Terran slaves there and tolerates no deviation from his strict rules. Relatively little is known of him, as no one in the Mirror Universe is aware that the wormhole exists or who Odo's people are. During a mining accident, Odo begins an evacuation of the Terran workers from the complex. Julian Bashir, seizing the opportunity to escape, disintegrates him with a disruptor. In this reality, Odo has his own set of rules called the "Rules of Obedience" and quotes one of the rules in the same way that regular universe Quark would quote the Ferengi Rules of Acquisition. After filming of the episode "Crossover", which was mirror Odo's sole onscreen appearance, actor René Auberjonois liked the mirror universe uniform so much he began wearing it while playing the regular universe version of Odo
