I did these for fun a few years ago while working on my TOS Chronology. I got to wondering how the events of TOS would have gone in the Mirror Universe. I personally find it fun to imagine that the MU crew of the I.S.S. Enterprise had dark, twisted versions of the adventures we saw on TV every week. I skipped a few episodes here & there, when an evil version of the plot didn't immediately suggest itself to me. And yeah, I included several episodes that happened or aired after "Mirror, Mirror," but I still included them because I thought it'd be fun. Here they are... THE CAGE Captain Christopher Pike escapes from Talos IV by using his aggressive emotions to overcome the Talosians. James T. Kirk plunders the laboratory of an unknown alien scientist and obtains the Tantalus Field Device, capable of wiping someone out of existence by the touch of a button. James T. Kirk’s enemies develop a sudden and mysterious habit of “disappearing.” James T. Kirk becomes Captain of the I.S.S. Enterprise through the assassination of Captain Christopher Pike with the Tantalus Field Device. In his first action as Enterprise captain, Kirk suppresses the Gorlan uprising through the destruction of the rebels’ home planet. Captain Kirk executes 5000 colonists on Vega IX. WHERE NO MAN HAS GONE BEFORE Stardate 1312.4 – 1313.8 Captain Kirk kills his old friend Gary Mitchell when Mitchell begins exhibiting powers, leaving his body to decay on the remote planetoid of Delta Vega. THE CORBOMITE MANUEVER Stardate 1512.2 – 1514.1 Upon discovering that the real Balok is a harmless child, Enterprise crewman Bailey slaughters him, claiming his advanced ship as property of the Empire.

Kirk forces Mudd to grant him all his past and future profits from the Venus drug and prostitution ring. THE ENEMY WITHIN Stardate 1672.1 – 1673.1 A transporter accident splits Captain Kirk into his good and evil halves. Kirk is repulsed to realize that his good qualities are part of what make him an effective starship commander. CHARLIE X Stardate 1533.6 – 1535.8 Captain Kirk gives his Captain’s Woman Janice Rand to the telekinetic Charlie Evans to be his new plaything. BALANCE OF TERROR Stardate 1709.2 After luring a Romulan Commander into thinking of him as a friend, Captain Kirk ruthlessly slaughters a Romulan ship armed with a cloaking device. DAGGER OF THE MIND Stardate 2715.1 Kirk journeys to Tantalus V and exposes Dr. Tristan Adams to his own neural neutralizer in order to prevent discovery of the Tantalus Field Device. Mr. Spock mind melds with Dr. Simon Van Gelder, driving him incurably insane. COURT MARTIAL Stardate 2947.3 Captain Kirk is accused of unnecessarily sparing the life of Lt. Commander Ben Finney. THE MENAGERIE Stardate 3012.4 When Commodore Mendez of Starbase 11 begins to suspect the true fate of Captain Christopher Pike, the Enterprise lures Mendez to the forbidden planet of Talos IV. Kirk protects his command by exposing the Commodore to crippling Delta Rays and stranding him on the planet’s surface. ARENA Stardate 3045.6 Captain Kirk combats a Gorn captain on Cestus III when the Gorn retaliate for Empire incursion into their territory. Kirk slays the Gorn captain through guile and treachery, proving to the alien Metrons that mankind is still a dangerously savage race. THIS SIDE OF PARADISE Stardate 3417.3 The Enterprise crew is mind-controlled by the colonists of Omicron Ceti III, making them peaceful and docile. THE DEVIL IN THE DARK Stardate 3196.1 Kirk and Spock slaughter the Horta’s egg chamber on the mining planet Janus VI, forcing the entire Horta race into extinction. THE CITY ON THE EDGE OF FOREVER No Stardate When a mutinous Dr. McCoy attempts to escape the ship, the Enterprise crew discovers the Guardian of Forever, a time portal on an unknown planet. OPERATION—ANNIHILATE! Stardate 3287.2 – 3289.8 Captain James T. Kirk murders his brother George Samuel Kirk on the planet Deneva. George’s son Peter swears vengeance against his uncle. THE DOOMSDAY MACHINE Stardate 4202.9 Commodore Matt Decker is lured to his death inside the planet killer. MIRROR, MIRROR Stardate Unknown Kirk, McCoy, Scotty and Uhura are accidentally transported into a parallel universe. THE TROUBLE WITH TRIBBLES Stardate 4523.3 – 4525.6 Captain Kirk releases a plague of Tribbles on Sherman’s Planet, poisoning their supply of quadrotriticale for generations.

THE DAY OF THE DOVE No Stardate Given The Enterprise crew’s warlike urges are drained by mysterious space creature. Between TOS and TMP Dr. Leonard H. McCoy is sentenced to an Empire penal colony. STAR TREK: THE MOTION PICTURE Kirk retakes command of the I.S.S. Enterprise, trapping Enterprise Captain Matt Decker within the exploding V’Ger. Kirk and his crew begin a second 5-Year Mission of conquest. STAR TREK VI: THE UNDISCOVERED COUNTRY The U.S.S. Excelsior destroys the Klingon moon Praxis, successfully sabotaging the Klingons’ key energy production facility. The Klingon Empire is brought to its knees and the terms of Klingons’ surrender are dictated on the U.S.S. Enterprise. I might come back to this list at some point. It's fun trying to come up with the most evil and twisted versions possible for TOS episodes. Anyone have any suggestions for others?
