Season 7, Episode 14 - "Chimera"
17 February, 1999
Returning from a conference, Chief O'Brien and Constable Odo are paid a visit by a Changeling. However, the Changeling calls himself a Metamorph. He, like Odo, was one of the one hundred shape-shifters sent out by the Founders at an early age in order to experience other species' ways of life. The Metamorph has been trying to return home ever since. Luckily, Odo is the first shape-shifter that the Changeling encountered.
