For the primary universe counterpart, see Tiron.

In the mirror universe, Tiron was a male alien who lived during the 24th century.

In the 2360s and 2370s, Tiron was a slave in the service of the Klingon-Cardassian Alliance in the mines of Korvat. In 2375, he was one of several escapees who fled to Terok Nor. Tiron was also a member or sympathizer of Memory Omega.

In 2376, Tiron worked with Keiko Ishikawa on a plan to get her a much higher position in the Terran Rebellion. Tiron accused her of continuing to work for the Alliance and later shot Keiko, who used a soporific to make it appear that he was dead. Tiron was later beamed away from Terok Nor by Chu'lak of Memory Omega. (DS9 - Mirror Universe short story: "A Terrible Beauty")
