* ConspicuouslyPublicAssassination: [[spoiler: Dukat]] gets his head blown off by [[spoiler: a Vulcan-influenced Damar]] as he's giving a speech to the Cardassian people.

* CulturePolice: In ''The Worst of Both Worlds'', it is mentioned that Alliance banned all "decadent" Terran works of art such as ''Literature/LesMiserables'' after conquering the Terran Republic.

* VestigialEmpire: It seems the Romulan Star Empire splinters and collapses no matter which universe we're in; the mainstream Literature/StarTrekNovelVerse, ''VideoGame/StarTrekOnline'', and now here. After the destruction of Romulus occurs early thanks to a thalaron weapon, the colonies are left to be conquered by Klingons or join Calhoun's resistance. [[spoiler: The Star Empire gets re-established after the Klingon-Cardassian Alliance collapses, and forms an alliance with the new Galactic Commonwealth]].

* SuperpowerfulGenetic: In ''The Mirror-Scaled Serpent'', Crell Moset tells B'Elanna that he has samples of Kes' DNA and that he may be able to splice it into B'Elanna's genetic structure, making her a telepath. In "Bitter Fruit", several months later, B'Elanna has developed telepathic abilities. She intends to offer the ability to create telepathic warriors to Regent Worf in exchange for a higher position in the Alliance.

* {{Foreshadowing}}: The fate of [[Literature/StarTrekVanguard Vanguard Station]] in ''The Black Flag'' is pretty similar to that suffered by the prime universe Vanguard, several (real world) years later.

* ThrownOutTheAirlock: In "The Black Flag", Captain Zhao Sheng throws Griffin out the airlock of the ''Eighth Happiness'' when he refuses to give him the unlock codes for the freighter's cargo bay. After several seconds, Zhao beams the half-frozen Griffin back aboard and demands the codes once again. Griffin still refuses so Zhao repeats the procedure. This convinces Griffin to tell him what he wants to know.

* VestigialEmpire: It seems the Romulan Star Empire splinters and collapses no matter which universe we’re in; the mainstream Literature/StarTrekNovelVerse, ''VideoGame/StarTrekOnline'', and now here. After the destruction of Romulus occurs early thanks to a thalaron weapon, the colonies are left to be conquered by Klingons or join Calhoun’s resistance. [[spoiler: The Star Empire gets re-established after the Klingon-Cardassian Alliance collapses, and forms an alliance with the new Galactic Commonwealth]].

* DividedWeFall: When O'Brien's Terran Rebellion and Calhoun's Xenexian-Romulan forces come together, the two leaders spend more time posturing and insulting one another than they do cooperating. This leads Memory Omega to impose itself on them as, essentially, their joint leader.

* SequelHook: In the final scene of ''Rise Like Lions'', The [[spoiler: Dominion]] finds the wormhole opening in the Gamma Quadrant.

* ThrownOutTheAirlock: A smuggler is tortured by [[Literature/StarTrekVanguard Zhao Sheng]] by being blown out the airlock, transported back onto the ship, then put back into the airlock. The third time round, the prisoner gives in and cooperates.

* TheAtoner: Damar, after wiping out pretty much every non-Cardassian servant or slave (''Rise Like Lions'' mostly focuses on the Vulcans, apparently because they're the ones that actually are responsible for the triggering events and because Vulcans are very popular as slaves) in the Cardassian realm. When it became clear their telepathy was behind the anarchy gripping Cardassia, he ordered the genocide, and it shattered his sense of worth. He seeks solace in the [[GoodOldWays Oralian Way]].
* BaitAndSwitch: "Muck" (the Mirror Universe Calhoun) meets Shelby (his wife in the regular universe) who's a slave. There's a connection between them as she aids Muck and seems to indicate they'll end up a couple in this universe as well...[[spoiler: and then Shelby is killed without warning]].
* BeAllMySinsRemembered: Just before his death, Emperor Spock records a message for the future. In it, he lists out all the people he murdered (including his own mother), all the worlds he destroyed, and all the crimes he committed in the name of his grand plan. He closes by saying he has become that which he opposed - a tyrant and a despot - and that history must not laud him but instead treat him as the villain he is.
* BeingHumanSucks: Vash, after her Tellarite and Vulcan companions smell and hear things, respectively, far sooner than she could, reflects that human senses are so often inadequate - and many races live longer as well.
* TheButcher: The Tellarite Gral (in the Prime Universe a diplomat) is known to the Terran Empire as "The Butcher of Berengaria".

* DrunkOnTheDarkSide: Kes starts succumbing to the temptations of her incredible psychic powers after [[spoiler: Neelix dies]], but comes down quickly when she realizes [[spoiler: she has seconds left to live.]]

* EnemyCivilWar: A large part of both Memory Omega and the Terran Rebellion's plan depends on driving a wedge between the two great powers of the Alliance. Cardassia and the Klingons indeed end up fighting each other.

* LastOfHisKind: The Dax Symbiont, following the genocide of the other symbionts on Trill.

* NecessarilyEvil: The actions Spock takes to ensure that the the spirit of the Terran Republic and freedom lives on are quite ruthless, and he knows it. He even calls himself a villain.
* OrbitalBombardment: In ''Age of the Empress'', the rebel fleet bombards Earth from space, devastating many cities including Beijing, Chicago, Kyoto, Mumbai, Paris, Rio de Janeiro and Stalingrad. In retaliation, the ''Defiant'' and a taskforce of Starfleet ships launch an orbital attack on the rebel stronghold Aldus Prime.

* PullingTheThread: Eddington does a beautiful job of this as he line by line exposes how [[spoiler: Sito Jaxa's journal on being pregnant]] was actually a complex code showing [[spoiler: she's an Alliance spy.]]
* PuppeteerParasite: Emperor Spock discovers that the [[Literature/StarTrekDeepSpaceNineRelaunch Kurlans]] have succeeded in infesting Trill, hijacking the elder egg-laying symbionts as a means of creating more of their body-stealing parasites. He orders every joined Trill to be put to death except for Curzon Dax, who serves as a reminder of what he has become.
* RevengeBeforeReason: Dukat, when asked by Damar what Cardassia has to gain from conquering Bajor in the wake of its secession from the Alliance, answers "Revenge!" He also throws his glass at the wall – hey, it's the mirror universe, it's supposed to be over-the-top.

** Kira has to become the underling tforgeo Ro.

* StarKilling: Trilithium warheads. In ''Rise Like Lions'', one is used to destroy the [[spoiler: Ferenginar]] system.
