!!YMMV items from the comics:

* CrazyAwesome: Calamity Jane is a [[TheLadette Ladette]] BoisterousBruiser SirSwearsALot who will shoot you if you don't show elementary gallantry toward women, constantly defies the DamselInDistress trope and generally rivals Luke in sheer badassery.
* EnsembleDarkhorse: The Daltons sometimes became even more popular than Luke. In fact, in the XilamAnimation produced series "Les Dalton", Lucky Luke doesn't even appear, and the focus is on the Daltons as they try to escape from prison.
** Rantaplan, to the point he got his own series;
** A minor exemple with Calamity Jane.
* MyRealDaddy: The majority of the fans refuse to acknowledge Laurent Gerra as Morris' successor.
** Technically, Laurent Gerra is the latest of the numerous Goscinny's successors, while Achdé is pretty faithful to Morris' drawing style.
* ReplacementScrappy: A rare inversion; the second set of Daltons have ended up becoming much more famous and iconic than the original.
* SeasonalRot: When Morris died and the series was written by comedian Laurent Gerra.
* VillainDecay: The Dalton Brothers have suffered quite a bit of it over the years. In ''Les Cousins Dalton'', their 1958 debute, they get the best of Lucky Luke, forcing him to service for a time. Within the story each brother is given different character traits. Joe is the mastermind, William is obsessed with guns and using everything on sight for target practice, Jack is a master of disguise. Averell is naive but also a superb boxer. In fact he fights Luke to a standstill. Luke only wins by using his cunning, not his fists. The two combatants agree to meet for a rematch and retreat to their own rooms for sleep. Only Luke manages to releases mosquitos in Averell's room. The following day, Luke is fresh after a good night's sleep, Averell has not managed to sleep at all. He can barely walk, much less fight. Since then, several stories portray them as incompetents.
* WeirdAlEffect: At least in Francophone Europe, the Dalton brothers from ''Lucky Luke'' are much more recognizable than the historical Dalton gang.

!!YMMV items from the movies:

* BigLippedAlligatorMoment: In Go West: A Lucky Luke Adventure, there is a woman who sings a musical number that has no relevance to the plot.
* CrowningMusicOfAwesome: The 2009 movie is scored by [[WesternAnimation/{{Coraline}} Bruno Coulais]]. This is inevitable.
* EarWorm: Every single song in "The Ballad of the Daltons".

!!YMMV items from the cartoons:
* EarWorm[=/=]CrowningMusicOfAwesome: the theme song for ''Les Nouvelles Aventures de Lucky Luke'' is [[https://www.youtube.com/watch?v=Z5jiulc5DRQ extremely catchy]]

!!YMMV items from the games:
* NightmareFuel: The GBC title ''"Lucky Luke Desperado Train"'' can get pretty creepy at times. Case in point:
** The BGM for the aforementioned "Explosive Mine".
** The SlasherSmile given by the guy in "[[RhythmGame Crazy]] [[UnexpectedGameplayChange Telegram!]]" if you screw up too many times (yup, someone working with a telegraph has a Slasher Smile - go figure).
** The ScareChord played when you die.
** A Continue option (available by collecting a silver coin with a hole in it) where you have to shoot faster than your own shadow: they managed to make the ''[[http://static.tvtropes.org/pmwiki/pub/images/050711_lucky_luke.jpg former image for the main article]]'' '''''creepy''''' thanks to DramaticWind and [[NothingIsScarier lack of music]].
** Most prominently, the GameOver screen, where you first see someone pointing a Gun at Lucky Luke's back (a Continue Screen available [[EasyModeMockery only in Sheriff mode]]) and then [[GoryDiscretionShot shifts]] to Barnaby the [[InexplicablyIdenticalIndividuals same-as-always]] undertaker as he holds his hands in cynical delight, with a poster reading Game Over (in typical "western" font). Can easily become High Octane for the most sensitive.
* CrowningMusicOfAwesome: one track in particular stands out, "[[http://www.youtube.com/watch?v=TEKIlV40WxI&feature=related Train]]" from the first GB/GBC Lucky Luke game. While the series itself shows pretty good music overall, this one is [[EarWorm bound to get stuck in your head for a while]].
* GoodBadBugs: A glitch exploited in an [[Website/YouTube out-of-sync-audio]] [[http://www.youtube.com/watch?v=e7szNFNsKkM&feature=related longplay]] allows a steamboat ''[[CrowningMomentOfFunny to ride the riverside]]''.
