- For the primary universe counterpart, see Martin Madden.
In the mirror universe, Martin Madden was a Terran male who lived during the 24th century. He was an operative of Memory Omega.
During the evacuation of Regula 1 in 2377, Madden was charged with transporting the Ocampa Kes to the new Memory Omega headquarters in an asteroid in the Zeta Serpentis system. However, Kes used her psionic powers to manipulate Madden into helping her commandeer the ship, allowing her to escape. She then altered Madden's memories to make him believe that he had successfully transported her to the new base. The truth of the matter was not discovered for several days. Although Curzon Dax held Madden responsible for Kes' escape, Saavik, the director of Memory Omega, did not as she assured him that there was no way that he could have resisted Kes' mental powers. Saavik immediately dispatched Tuvok to recapture Kes on Terok Nor. (ST - Mirror Universe novel: Rise Like Lions)
