Following the Terran Rebellion's defeat of Regent Worf, "Smiley" O'Brien instructed her to "debrief" Ezri Tigan, which Leeta apparently took literally. When Rom told her "We're married!", she gave him a disgusted look and sneered, "I don't think so...!". Like Ezri and the Intendant, Leeta seemed to prefer female companionship. (DS9: "The Emperor's New Cloak")
Leeta was played by Chase Masterson. She commented: "I absolutely loved playing mirror Leeta because she is so deliciously evil. She would eat the Borg Queen for breakfast and come back for seconds. She is ruthless and selfish and everything regular Leeta is not. It is really fun to get into that character and to realize the depth in that people are only that vicious and selfish out of fear. So, it really is a multi-layered character that is fun to get into". 
The mirror Leeta also features prominently in the computer game Star Trek Online, voiced by Chase Masterson. Depicted to be an opportunistic captain of the reborn Terran Empire, Leeta collaborates with the True Way in an effort to invade the prime universe and conquer the Federation. In later missions, she is promoted to the rank of Admiral and commands the ISS Enterprise, the mirror counterpart to the USS Enterprise-F. Admiral Leeta commands the Terran forces of the "Temporal Liberation Front" at the Battle of Procyon V, and leads boarding parties onto the USS Enterprise-J to disable the Tox Uthat before it can be used to destroy the Sphere-Builders' command sphere. When she is defeated by the player character, she abandons her "allies" and returns to her Enterprise, escaping back to the mirror universe. She later returns in the "Reflections" story in September 2021 as a defector from the Empire, intending on warning the expanded "Khitomer Alliance" about the as-yet unidentified Terran Emperor's intention of using a frightening yet currently unknown super weapon that could destroy both the prime and mirror universes.
