* 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.
