* AllThereIsToKnowAboutTheCryingGame: Most people nowadays have heard of this movie because it's "that movie with the exploding head", and if they're watching it, it's so they can [[WatchItForTheMeme see the part with the exploding head]].
%% Bring CompleteMonster examples to this thread before adding any: http://tvtropes.org/pmwiki/posts.php?discussion=6vic3f9h1cy5qivsenw8llok&page=1. Check the FAQ first to see what would qualify characters for the trope, and if there has been previous discussion on the work.
* CrowningMomentOfAwesome: Revok's moment is [[YourHeadASplode obvious]]. Vale's is probably the final twist in the film.
* EvilIsCool: Revok, that MagnificentBastard
* FirstInstallmentWins: Did you know there's four more Scanners films? No? Not surprising, considering the {{sequelitis}}.
* FridgeBrilliance: The scanner duel between Vale and Revok. [[spoiler:Revok has taught himself how to kill people horrifically with his powers as befits his methods and goals as a psychic terrorist, hence the severe hemorrhaging he easily inflicts during his attempt to "suck (Vale's) brain dry". Vale received far more expert training from first Ruth and then Obrist, and is capable of just as much more subtlety, such as [[{{Technopath}} scanning a computer]] over a ''phone line.'' Vale is thus mortally injured almost as soon as the duel begins, but eventually calls on that training to enter a state of TranquilFury and [[BeCarefulWhatYouWishFor give Revok exactly what he demands]] - and [[GrandTheftMe then some.]]]]
* FoeYay: In ''Scanners 2'', Drak constantly calling David "pretty boy".
* HilariousInHindsight: "Nobody's ever 'switched off' a scanner before."
** Arguably also the name of Dr. Ruth, considering this was just before ''that'' [[http://en.wikipedia.org/wiki/Dr._Ruth_Westheimer Dr. Ruth]] started becoming more well-known. Cronenburg possibly knew about her, as the Dr. Ruth in Scanners was once [[spoiler:a chemist researching drugs for pregnant women.]]
* MemeticMutation: The infamous YourHeadAsplode scene is used as a reaction image, especially on Website/{{Cracked}} and ToplessRobot.
* {{Narm}}: The sequels increasingly narm things up in general. Scanner duels also seem to gradually devolve into "whoever makes the weirdest face wins".
* {{Sequelitis}}: The sequels did not involve any of the original cast or crew, and rapidly decrease in quality.
* SignatureScene: [[http://www.youtube.com/watch?v=HY-03vYYAjA Guess.]]
* VisualEffectsOfAwesome: Dick Smith's makeup effects are still very impressive over thirty years after the film's release.
* WatchItForTheMeme: Many have sat down to watch the film purely for the head explosion scene.
