- Acceptable Targets: College students, if the Malphas series is any indication. The four-part series loves to portray them in a negative light, especially when it comes to intelligence levels. A justified example, as the story outright states that the students at Malphas college are the students who couldn't go to any other college due to bad grades or behavior... Averted however with some of the students, such as Nadine Limon.
- Creepy Awesome: Chess, Bone and Chair, and many more.
- Crosses the Line Twice: Those moments of Black Comedy involve extreme violence or sex, and usually go so far, it often reaches Narm territory.
- Designated Hero: Daniel Saul from Hell.Com is considered this due to his Jerkass attitude and womanazing habits for the first third of the book. The fact that he raped a girl years ago made some people completely stop caring about him, to the point that some were happy that he got killed at the end of the book.
- Draco in Leather Pants: Bone, Chair, Chess, Maxime Lavoie, to name a few.
- Ensemble Dark Horse: If a character is a beacon of hope and general human decency in one of the darker Senécal books, they tend to become fan favorites for adding some much-needed levity.
- Harsher in Hindsight: The ending of Le Vide is this, now that shootings have become more commonplace since 2012.
- Hilarious in Hindsight: One of Senécal's less famous books, Le passager, was released in 1995, one year before the book Fight Club. Both have the same twist, although the version in Le Passager is nowhere nearly as intricate as the one in Chuck Palahnyuk's story and the film that was made afterwards.
- It's the Same, Now It Sucks!: A common criticism of Hell.Com, as it is very close in style (and tone) to other grim, realistic stories written by him previously, such as Le vide and Les sept jours du talion.
- It should be noted that Patrick Senécal's other writing style is "supernatural horror with hints of black comedy", which at least offers some levity compared to the thrillers, that feel a lot heavier by comparison.
- Narm: Are we supposed to find Simon Saul's tongue clacking scary?
- Protagonist-Centered Morality: How much people did Daniel Saul let being brutalized, drugged, raped and killed by Hell.Com in order to find and save his son? Not that he could do much, mind you, but it's still jarring.
- The Scrappy: Simon Saul from Hell.Com didn't get much sympathy for being a Jerkass Spoiled Brat suffering from Wangst who tortured and mugged someone on the streets (to the point that the street gang he was with found him crazy and rejected him for doing that). Even if Charron had a hand in it, he also killed someone for Hell.Com and had no remorse for doing that. He also drags himself in dangerous situations for idiotic reasons (he went to participate in a caged death match in a pitiful state just because "he wanted to feel alive by taking someone else's"). It doesn't help that his "Character Development" comes at the very end of the book and feels rushed, as he feels sorrow for losing his dad due to his stupidity, making it a 180° of what he was during the rest of the book.
- What an Idiot!: Seriously, Simon Saul, was it a good idea to drug yourself before a death match??
YMMV / Patrick Senécal
