History YMMV / DianeDuane

* HarsherInHindsight (a plot to blow up the WTC in the 1995 ''Franchise/{{Spiderman}}: The Octopus Agenda'')

* EvilIsCool: [[AvertedTrope Averted]], surprisingly enough in ''Dark Mirror''. The mirror Enterprise-D is a downright miserable place to serve on; everyone is on a spectrum from StupidEvil thug to beaten-down victim, the paranoia and oppression are relentless, and [[ArsonMurderAndJaywalking prime-Geordi thinks your uniforms look dumb.]] Especially evident when contrasted against the prime universe crew of TrueCompanions who all clearly adore each other.
* JerkassWoobie: MirrorUniverse Ensign Stewart is a confirmed JerkAss, but his hopeless situation and powerlessness makes him more pitiable than anything else.
* RescuedFromTheScrappyHeap / GoodTroiEpisode: ''Dark Mirror'' give Deanna about a dozen [[TookALevelInBadass levels in badass]].

* HarsherInHindsight (a plot to blow up the WTC in the 1995 ''{{Spiderman}}: The Octopus Agenda'')

* TearJerker: ''The Wounded Sky''. Just... ''The Wounded Sky''.

* CompleteMonster: The remnants of the civilization that exist on the "Intellivore" planet. They feed off of LifeEnergy, and though that's portrayed as not really their fault that they evolved that way, we later find out that the entities ''preserve the memories of the agonized deaths of every single person they've killed over the millennia.'' Why? Cause those memories are ''[[EvilTastesGood the most delicious.]]''

* DidNotDoTheResearch: ''Inaieu'', the super-sized battlewagon, is said to be a "destroyer". ''Franchise/StarTrek'' tends to follow 20th/21st century naval parlance, in which destroyers (from "submarine destroyer") are somewhere between frigates and cruisers like the ''Enterprise''. (Then again, definitions do change over time: "frigates" used to be Ships of the Line.)
** That's how the Romulans call her, possibly short for "destroyer of any other ship". And the encounter between ''Inaieu'' and the Romulan-crewed D7 ''Battlequeen'', ended after ''Inaieu'''s first half-hearted salvo disintegrated the target, shows that ''Inaieu'' is indeed a destroyer of anything else...
