* KlingonScientistsGetNoRespect: Rom.

* GenreSavvy: The Cardassian-Klingon Alliance. After the first crossover ultimately led to [[NiceJobBreakingItHero the collapse of the Terran Empire]], the Alliance went to a lot of trouble to prevent further crossover, such as redesigning transporters to prevent any more crossovers and issuing orders to kill anyone from the main universe on sight, on the grounds that [[ForWantOfANail just a couple people from the other side could seriously alter the course of their history again]]. As it turns out, they were completely right. When a second crossover finally happens, it triggers a full-scale rebellion.
** When Vedek Winn asked Mrs. O'Brien not to teach anything about the wormhole, wanting Bajoran spiritual beliefs taught along with Federation science, Keiko knew exactly where this would lead and asked "what about when we get to evolution, or the creation of the universe?"

** D'Ghor's reaction suggests that this is a deadly insult to a Klingon.

** In The Wire, Quark tries to get some information from a certain Cardassian officer named Bohica[[labelnote:*]]Bend Over, Here It Comes Again[[/labelnote]], but it's way above his pay grade.

** In her early stage in her development (Terry Farrell was the last actor cast with little prep time before shooting began) Dax walks around with her hands behind her back like a holy woman at Lourdes. Though it could be argued that Curzon and the others start to influence her behavior more.

* LargeHam: Sisko, on occaision; Dukat; Quark; Garak; Weyoun; [[spoiler: the fake]] Gul Darhe'el''; Hagath.

* EvilvsEvil: The war between [[TheEmpire Terran Empire]] [[LaResistance rebels]], and the Cardassian-Klingon Alliance, in the episodes involving the MirrorUniverse.

** ''The Fallen'', a FirstPersonShooter showcasing the Cult of Pah-Wraiths, who made a few appearances on the show. The plot, a yarn involving EvilCounterpart versions of the Prophets--complete with ''red'' orbs and a ''red'' wormholes--is based on the Relaunch novel ''Millenium''.

* EasilyConqueredWorld: Betazed was taken over during the Dominion War with minimal effort and nobody around to even try and put up a fight.
** Either this, or could be an example of CurbStompBattle, something the Dominion is fond of doing. Either way, it's used to demonstrate how badly the war is going.

* IntimateMarks: An exchange between Jadzia and a [[GirlOfTheWeek Boy of the Week]] provides the page quote. Starting with this series Trills all have dual rows of spots starting at their foreheads and continuing down their sides to their feet. A minor RunningGag is that non-Trills would like to know just how far down the spots go. This was {{enforced|Trope}} over the RubberForeheadAliens look used in the Trills' debut in Series/{{TNG}}: "[[Recap/StarTrekTheNextGenerationS4E23TheHost The Host]]" because the [=DS9=] TV crew thought the TNG makeup made Terry Farrell look ugly.

** The Bajorans were shown "In the Hands of the Prophets" to applaud by tapping the dorsum of their hands, and in later episodes, they simply clapped normally. the show would later establish that Bajorans clap the back of one hand into the palm of the other.

** In the early seasons, the Bajorans were shown to applaud with both palms, though the show would later establish that Bajorans applaud with the back of one hand into the palm of the other.
