The TV Series
- Cargo Ship: Wynonna really, really loves her motorcycle.
- Complete Monster: The Jack of Knives. He is Jack the Ripper after all. He continues his trend of butchering women by even taking on a protégé and tricking him into believing that a person's organs can being taken out and rearranged to cure them of potential illness. He almost does the same to Wynonna before she is rescued by Doc and Dolls.
- Ensemble Darkhorse: The Blacksmith (a white-magic user who appears in two episodes before dying) Chrissy Nedley (the only friend of Waverly's who seems to actually be worth the label).
- Officer Haught qualifies as well, appearing in nine of the thirteen season one episodes but only having anything resembling significant screentime in three of them (7, 9, and 12). She's so popular that she's frequently included by fans in anything involving the main characters, and there have been rampant campaigns to make her a series regular if the show gets a second season.
- Nightmare Fuel: The Revenants. The fact that they take on an outwardly human appearance until they reveal just how much Hell has changed them.
- Narm: A lot of the drama in the two flash back scenes involving Wyatt and Doc's last two meetings gets shot down by the actor playing Wyatt' incredibly thick Canadian accent. For the record, the real Wyatt was born and raised in the American Midwest.
The Comic book
- Anti-Climax Boss: At the end of the "Home on the Strange" arc, Wynonna is confronted by the "him" who even the other immortal Cowboys are afraid of — Johnny Ringo. It's set up to be an epic fight, but then Wyatt's ghost distracts Ringo, giving Wynonna a chance to shoot him in the back.
- Evil Is Sexy: Dr. Sasha Tarasov.
