In the Season Five opener, "Apocalypse Rising", Odo discovers that his race is capable of deceiving their own kind, as well as "solids", when he is led to believe that Klingon Chancellor Gowron is a Changeling instead of the General, Martok. This plot was planned to shift the focus of "" episodes back toward the struggle with the Dominion, which had been postponed in earlier production discussions with Paramount in favor of bringing Worf and a Klingon-based plotline into the series.
