YMMV items from the comics:
- Crazy Awesome: Calamity Jane is a Ladette Boisterous Bruiser Sir Swears-a-Lot who will shoot you if you don't show elementary gallantry toward women, constantly defies the Damsel in Distress trope and generally rivals Luke in sheer badassery.
- Ensemble Darkhorse: The Daltons sometimes became even more popular than Luke. In fact, in the Xilam Animation 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.
- My Real Daddy: 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.
- Nightmare Fuel: Bob Dalton's onscreen death via headshot◊. The one panel in which he calls out for his mother as he dies hanging from the lantern showing only his feet suspended and something (it's probably the oil from the lamp but with the way it's portrayed like forming a pool underneath him the next panel) dripping below makes a chilling image. Yikes... No wonder Dupuis asked Morris to change it.
- Replacement Scrappy: A rare inversion; the second set of Daltons have ended up becoming much more famous and iconic than the original.
- Seasonal Rot: When Morris died and the series was written by comedian Laurent Gerra.
- Villain Decay: 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, and in some stories William and Jack may as well be interchangeable for all the characterization they get, if they are not relegated to background status within the group, where Joe and Averell tend to get the spotlight almost exclusively.
- "Weird Al" Effect: 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:
- Big Lipped Alligator Moment: In Go West: A Lucky Luke Adventure, there is a woman who sings a musical number that has no relevance to the plot.
- Crowning Music of Awesome: The 2009 movie is scored by Bruno Coulais. This is inevitable.
- Nightmare Fuel: In the movie Daisy Town the showdown between Luke and the Daltons starts of as rather sinister with ominous music playing, the Daltons ready to kill and the whole town pausing at whatever they were doing to listen to the sound of the approaching combatants. And then the whole thing ventures to purely comedic Nightmare Retardant thanks to Lucky Luke's plan.
YMMV items from the cartoons:
- Ear Worm/Crowning Music of Awesome: the theme song for Les Nouvelles Aventures de Lucky Luke is extremely catchy
- Tear Jerker: Despite the original source material and any other adaptations thereof is far from being a treasure trove of emotions (given that it's a comedy, spaghetti western parody and all), there's something surprisingly poignant about Cynthia's plight in the "The Daltons Cowboys" that makes you sympathize with her a bit as the episode goes on. Sam laments that being in her thirties, she's not getting any younger but he still hopes that she find a husband. Upon meeting the Daltons, she immediately develops a crush on Averell then later becoming an Abhorrent Admirer who made Averell so miserable, he begged for her to let him go back to be with his brothers. After having thought of being deceived (thanks to Joe's plan when he was disguised as Averell and having tricked her into opening her father's safe), she seeks vengeance on Averell during her rampage but Lucky Luke stops her just in time, and tells her that love has made a crazed fiend out of her to which she responded with tears. Her father says that it's her first love and acknowledges that it's always the worst. He reassures Luke that she'll get over it. Then cut to the ending — once Luke takes the Daltons back to prison, Cynthia steals one last glance. She gives way to a whimper (possibly repenting), then goes back to fixing the farm's roof, more upset than ever. It's one of the few, if not only, truly bittersweet endings.
- Judging from the situation Averell was put through, he was a total woobie from start to finish with Cynthia's relentless crush and Joe forcing him to stay with her good side for the sake of revealing the location of her father's money in order for them to steal it. His smile as Luke sends them away back to jail is the "sweet" part on the aforementioned bittersweet conclusion of the episode.
YMMV items from the games:
- Nightmare Fuel: The GBC title "Lucky Luke Desperado Train" can get pretty creepy at times. Case in point:
- The BGM for the aforementioned "Explosive Mine".
- The Slasher Smile given by the guy in "Crazy Telegram!" if you screw up too many times (yup, someone working with a telegraph has a Slasher Smile - go figure).
- The Scare Chord 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 former image for the main article◊ creepy thanks to Dramatic Wind and lack of music.
- Most prominently, the Game Over screen, where you first see someone pointing a Gun at Lucky Luke's back (a Continue Screen available only in Sheriff mode) and then shifts to Barnaby the 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.
- Crowning Music of Awesome: one track in particular stands out, "Train" from the first GB/GBC Lucky Luke game. While the series itself shows pretty good music overall, this one is bound to get stuck in your head for a while.
- Good Bad Bugs: A glitch exploited in an out-of-sync-audio longplay allows a steamboat to ride the riverside.
