Tuvok (mirror)

Tuvok in the mirror universe was the husband of T'Pel and father of Sek, Varith, Elieth and Asil (though Sek died of an infection later on in life). He and his family lived under oppression from the Klingon-Cardassian Alliance. When Captain Benjamin Sisko started the Terran Rebellion against the Alliance, he joined and told his new comrades that the Alliance murdered his family as a way to ensure no-one suspected him of deceit. As time passed, Tuvok experienced more and more battles, quickly becoming a coldly-logical soldier and hot-blooded killer, though retained contact with his family, all of which had joined the Rebellion; with his wife as a soldier on Memory Omega and his children undercover working as slaves in Alliance facilities, passing on information to the Rebellion.

When Sisko was killed by the Alliance, Tuvok ended up being the only voice of reason during the heated discussion between different factions of Sisko's troops. He openly opposed Bashir and Rom's suicide attack plan on Terok Nor, saying it would waste the few resources they had. (DS9: Through the Looking Glass)

Tuvok left the resistance cell and joined another, led by Captain Chakotay, who operated a small group of rebels from a base in the Badlands on the raider ship Geronimo. Their group led constant hit-and-run raids on Alliance territory and often used the Badlands's plasma storms to escape.

In 2371, While fleeing from Gul Evek after a raid, Tuvok and his cell encountered Neelix; an alien from another part of the galaxy and learned his companion Kes; an extremely powerful telepath, was in Alliance custody. Realising the Alliance couldn't be allowed to harness her powers and after enough persuasion (possibly with "assistance" from his telepathic abilities) Chakotay authorised a rescue mission.

The plan was undone however, when the Geronimo's chief engineer, Kate Janeway, turned out to be a spy for the Alliance and helped capture the group. Tuvok and the rest of his group were freed by Harry Kim, and when alone, Tuvok secretly contacted his wife and arranged for her to help make Kes disappear as she would never be safe as long as she remained among the other rebels. After Kes's "ascension", Tuvok and the rest of his group escaped back to Rebellion territory on the Geronimo and he took an extended "religious vacation", when in fact he left for Memory Alpha to help Kes control her abilities and use them against the Alliance.
