Unnamed Changelings This is a list of unnamed Changeling s . Earthbound Changelings . An unknown number of Changelings infiltrated the population of Earth in 2372 . A Changeling was hidden at the room where the Antwerp Conference was taking place , and was believed to be responsible for the bombing of the conference . It was determined by Starfleet that this Changeling had most likely survived the attack . Another Changeling , imitating Admiral Leyton , was exposed by Odo . When they met the Changeling , Leyton was rude to Odo and kept commenting on Odo ' s ability to assume different shapes . Odo , sensing something was wrong , extended his hand to shake with Leyton ; when he refused , Odo grabbed him , and they linked , exposing the Changeling . ( ) Shortly after this encounter , another Changeling , or possibly the same , startled Benjamin Sisko when he appeared to him in Miles O ' Brien ' s form , explaining to him their strategy of creating distrust among Humans and claiming that only four Changelings were at the time operating on Earth . He told him that if a few Changelings could cause so much panic , think what an invasion would do . ( ) Infant Changeling . A dying infant Changeling was found by Quark and sold to the Human Odo in 2373 . When Dr . Bashir was able to save it , it was cared for and investigated by Odo , who saw it as an opportunity to reconnect with his people . He attempted to teach it to shape shift using basic encouragement , rather than the more painful electric jolts that had been used on him , but his initial attempts failed . When Dr . Mora , who had raised Odo , arrived on the station , Odo was not pleased . He was still resentful of the invasive procedures Mora had used on him . They immediately clashed over the raising of the infant , but , as Odo was making little progress with the infant , and Starfleet was threatening to take the infant , Odo accepted Mora ' s help . Both of them bonded as the Changeling began to take shape , realizing the advantages in the other ' s methods ; it only began to shape - shift because of Mora ' s electric shock methods , but because Odo had made an effort to talk to it , it showed an interest in him , forming a face with eyes to peer at him . However , it became sick again , and , despite the efforts of Doctor Bashir , it eventually died . However , as thanks for what Odo had tried to do for it , the Changeling merged into Odo , causing him to regain his shapeshifting abilities . ( ) Changeling trio . A trio of unnamed Changelings , consisting of two males and a female , were , alongside the Female Changeling , the first Changelings to meet Odo upon his return to the in 2371 . The Male Changeling initially thought that Odo was not ready to experience the Great Link . ( ) Changeling on Torga IV . This Changeling was aboard a Jem ' Hadar fighter which crashed on Torga IV in the Gamma Quadrant in 2373 . The Changeling suffered severe physical trauma due to a failure of the inertial damper systems prior to the crash , which had killed the ship ' s Jem ' Hadar and Vorta crew . When the ship was discovered by a Starfleet crew led by Captain Benjamin Sisko that had been conducting a mineral survey on the planet , the Changeling disguised itself as a console inside the ship . When another Jem ' Hadar unit , commanded by the Vorta Kilana , arrived to secure the Changeling ' s rescue , they were unwilling to fire weapons near or within the ship to avoid harming the Changeling . Kilana was also unwilling to tell Sisko the true nature of her mission out of the mistaken fear that the Starfleet crew might kill the Changeling or use it as a hostage . After several hours of holding its shape , the Changeling succumbed to its injuries and died . Out of shame for having allowed one of their gods to die , the Jem ' Hadar committed suicide . Unable to stop Sisko from taking the ship , Kilana requested , and was granted , permission to remove a portion of the Changeling ' s desiccated remains to take back to the Dominion . ( )
