Worf (mirror)

In the mirror universe, Worf, son of $𝜇$ (2340-2379) was the Regent and commander-in-chief of the Klingon-Cardassian Alliance during the 2370s. He was the elder brother of $𝜇$.

He gave $𝜇$ the assignment of Intendant of $𝜇$ in 2368 as punishment for spurning his "crude advances." 

After the capture of $𝜇$ by the Terran Rebellion in 2372, Worf lead a fleet of Alliance ships to reclaim the station aboard his flagship. However the rebels with the help of our universe's Benjamin Sisko were able to complete a version of the Defiant and successfully defended the station forcing the Regent to retreat. 

In 2375, Worf was captured by the Terran Rebellion after his ship was disabled by a cloaking device brought to the mirror universe by Quark and Rom. 

After his capture, he was briefly held on Terok Nor, before being moved to a location in the Badlands. 

In his absence, he was deposed as Regent and replaced by $𝜇$. 

Despite his status as a major antagonist to the Rebellion, Worf was treated fairly in his confinement. He was allowed to decorate his prison cell according to Klingon tastes, was given Klingon food to eat, and was not harassed by his guards. After the final Terran victory and the defeat of the Alliance in January 2379, Worf was visited by $𝜇$, who released Worf from confinement, handed him his d'k tahg, and told him he was free to go. Worf immediately committed Klingon ritual suicide; with his dying words he thanked O'Brien for allowing him to regain his honor in death. 

Dark Mirror
In one permutation of the mirror universe in which the Terran Empire survived into the 24th century, all non-$𝜇$ and non-Vulcans were termed "slaves", including crewmember Worf, who - not being a warrior - wore no baldric.

After a meeting with Jean-Luc Picard of the USS Enterprise (NCC-1701-D), Worf told Picard that the entire Klingon race had been conquered centuries earlier. Picard urged Worf to be the force of change in his universe, as the Terran Empire (which was referred to as the United Empire of Planets in that timeline) had grown too large to sustain itself based solely on conquest, and would collapse within a century. 

Dark Passions
Worf was the son of Mogh, who along with his wife $𝜇$, was killed by Rihannha in the $𝜇$, as were 3,998 other Klingons. The first ship to come to the rescue included officer Ja'rod, who adopted the orphaned Worf. As a member of Ja'rod's family, Worf was an opponent of $𝜇$.

Worf's brother, $𝜇$, died in a second massacre at Khitomer shortly after the first one. Worf was, in fact, the only survivor of the two attacks.

His closest political ally was $𝜇$, who would frequently support him against senseless demands from the leader of the $𝜇$, $𝜇$.

Worf's ship was the, and the ship's first officer was $𝜇$.

Early in Worf's time as an Alliance captain, he met $𝜇$ at an Orion spaceport.

As of 2369, Deanna Troi - the Intendant of Betazed - was Worf's servant woman and the two called each other Imzadi.

It was in 2369 that Worf initiated a battle against the Rihannsu for the good of the Klingon Empire and was visited by $𝜇$ and $𝜇$. 

At their advice, Worf passed through the Elas system, but was refused assistance from the Dohlman of Elas, so he blew up one of her ships. The Elasians then begged for forgiveness. After the incident, Worf began planning a Kot'Baval Festival and hoped to install Duras as the Empire's Overseer. He looked forward to drinking Trakian ale during both events.

Later, Worf joined Troi, Kira and $𝜇$ in a meeting regarding deep-core mining chaired by $𝜇$. It was shortly after this that K'Mpec died in his sleep, whereupon Gowron summoned Worf back to Qo'noS. Gowron was eventually elected as the new High Chancellor.

When Troi was in the process of giving birth to her and Worf's child on the planetoid New Hope, she was murdered by Kira, who then comforted Worf in his grief. Worf's investigation into Troi's death led him, as per Kira's plans, to blame the Andorians, so he went to Andor and slaughtered virtually every Andorian existent, on Andor and its two sister planets. Worf named this victory the Great Andorian Massacre.

After Worf discovered the true killer of Troi, he and Torres assisted Agent Seven of Corps Nine in her plan to overthrow Kira as Overseer. This was accomplished with the acquisition of an Iconian portal. Worf's help in this matter is later publicly submerged.
