* EnsembleDarkhorse: Ben/X5-493 only appeared in one episode, but proved popular with the fans. And with the writers, so that they decided to bring JensenAckles back as his clone, albeit with a very different personality.
* FanPreferredCouple: Max and Alec, despite the pseudoincestuous aspect noted on the main page.
* HoYay: Normal's "gladiator" dreams about Alec. Also a CrowningMomentOfFunny.
* IAmNotShazam: Occasionally one finds people on the internet who think Max goes by the name "Dark Angel". She doesn't. It's a reference to her dark past, dark complexion, angelic features, and job as a bike messenger.
** "Angel" because from the pilot onwards she becomes a (beautiful female) hero to the downtrodden, and "Dark" because she has bleak past as a government-engineered super-soldier/assassin, and a somewhat dubious present as a part-time cat burglar, and ''not'' of the Robin Hood variety.
** The angel - messenger connection is made explicit in "Art Attack" when she prevents a man from committing suicide and introduces herself as a messenger, which he thinks means "of the Lord".
* JustHereForGodzilla: Many people on forums confess to only watching for Creator/JensenAckles. Unfortunately, this usually means they watch only "Pollo Loco" and Season Two and thus don't appreciate that Season One is also good.
** Both Creator/SkyOne and Creator/{{SyFy}} in the UK (when it was still Sci-Fi) implied in their trailers that the main reason to be watching was Creator/JessicaAlba. This proved to be the case for [[TestosteroneBrigade a lot of people]] (and unlike Jensen Ackles, she appears in every single episode).
%%* MagnificentBastard: Lydecker.
%%* TheScrappy: Asha. Just... Asha.
* SpecialEffectsFailure: Gossamer. Dammit, the Dark Overlord from Film/HowardTheDuck looked better!
* TheWoobie: Joshua. Between having to kill his deranged brother Isaac to protect Max and Ames White murdering his girlfriend Annie, it's a wonder he's still well-adjusted.
* BrokenBase: A lot of it between their first two and latter two albums, but the main points of contention are Don Doty vs. Ron Rinehart and the general decrease in brutality after ''Darkness Descends''.
* FaceOfTheBand: Gene Hoglan.
* SequelDisplacement: It's not by any means the best (neither in fame or in quality), but there was indeed an album before ''Darkness Descends''. Not helping matters is that one of the songs on the album was recorded again for ''Descends''.
* SignatureSong: "Merciless Death" or "The Burning of Sodom".
