Shane in the 24th century

The Changelings were a liquid-based shape-shifting species native to the Gamma Quadrant. They served as the leaders of the Dominion and were referred to as the Founders by the various Dominion species, who revered them as gods. The majority of Changelings were joined together in the Great Link. (Star Trek: Deep Space Nine)


Constable Odo, security chief of Deep Space 9, was a changeling. (Star Trek: Deep Space Nine)

In 2372, Section 31 created a morphogenic virus and infected Odo, who unknowingly then infected the Great Link. By 2375, the virus had progressed so far as to threaten the Changelings with extinction. A cure was devised by Dr. Julian Bashir, and after the end of the Dominion War, was passed to the link by Odo. (DS9: "Extreme Measures", "What You Leave Behind")

Sometime before or during 2391, the Traveling Link, in a radical attempt at procreation, transformed the Angosian Diggs into a Changeling. The change caused Diggs' unruly tendencies to be imprinted on the Traveling Link, leading them to harass the colony world of Gault. (Star Trek: Phoenix-X: "The Needs of the Plenty")
