The Female Changeling was a near copy of the Female Changeling that plagued Odo. This Female Changeling also acted as a spokes-person for the Great Link, and constantly worked for Daniel's attention. After Daniel left the Changeling homeworld, she spent the next few centuries trying to persuade him to return. (Star Trek: Phoenix-X)
By the time the Dominion war with the Federation had begun, she was deemed a traitor to the link and responsible for Daniel's actions. When Q allowed Daniel to alter the timeline, in 2375, in order to save a great many lives, it turned out that the Female Changeling's life was also spared. Not expecting this, Q realized her continual existence was a threat to the Q Continuum, so he took her away. ("The Links' Traitor")
- This Female Changeling's fate is unknown.
