Boomerang Bigot: Kit hates wizards and the things they make. Her father was a wizard.
Celibate Anti-Hero: Kit takes great pride in being living proof that a devikin can make something of herself without having to prostitute herself. A flashback shows that she's so dead-set on Poe and herself avoiding getting stained with the Horny Devils image that she insists that neither of them have any sex at all.
Aptly demonstrated again here, where she shoots the hammer of a revolver in midair and causes it to fire into the man's face.
Lovecraftian Superpower: At first glance, The Dreadful just appears to be a spell-like giant energy beam. But as Jeanne reveals, it has a side effect that produces The Virus.
Made of Iron: In the space of maybe a couple hours, Kit gets roughed up by zombies, takes a shotgun blast to the chest point blank, and still has enough left in the tank to go a couple rounds with Jeanne Noelle, with no apparent lasting injury. After escaping from Jeanne, she falls down a steep, rocky hill into a river and is captured by the JDA. She proceeds to open up a can of whoop-ass on them after being butt-stroked in the gut with a rifle. While her hands are tied.Sabueso has to completely hog-tie her to subdue her - and she still doesn't stop talking trash.
Blood Knight: Jeanne really seems to relish the idea of fighting Kit. When Kit looks like she's ready to reveal her Superpowered Evil Side, Jeanne's response is, "This is turning out better than I expected."
Hyper Awareness: Jeanne could hear the hammer click on Kit's revolver from the bushes at least 20m away. She immediately knew, apparently just from the sound, that A) it was Kit, and B) Kit was decocking rather than cocking the hammer.
I Am Not Left-Handed: When Jeanne is fighting Kit, she moves fast enough to Dodge the Bullet, but slow enough that Kit can dodge her attacks. Until Kit manages to get her gun to the back of Jeanne's head. Kit didn't even have a chance to react to the following punch.
Large And In Charge: Jeanne Noelle is probably one of the largest characters in the comic. She leads a group of bandits (and apparently has quite a bit of leverage over officials).
X Marks the Hero: Erin has one of these scars right in the center of her forehead, presumably because that's where Liz shot her.
Chekhov's Gunman: Introduced as a dead fairy in a bottle that Liz forgot about. Ends up resurrecting Erin.
Fairy in a Bottle: The strip initially uses this as a parody of the Zelda example, where Liz remembers that she's got one when she pulls out a long dead bottled fairy and throws it at Erin. Then made more plot relevant, when it turns out the fairy, Ith, was a necromancer and proceeds to possess/resurrect (apparently something goes wrong and they end up Sharing a Body) Erin after Kit and Liz have left.
Combat Pragmatist: He has no problems with fighting dirty. He ambushes Kit immediately after she gets badly beaten up by Jeanne, and his horse stabs Liz In the Back. Fortunately for Liz, she hired an illusionist beforehand, and thus only an illusion of her gets murdered.
From a Certain Point of View: Assures some members of the JDA that Kit is weak and vulnerable after her run in with Jeanne and being tied up. She promptly starts to beat them to a pulp. He continues to insist that she's weak and vulnerable. Relatively.
What Measure Is a Non-Human?: Used to work for the government, but "left" after botching a rescue operation. He was supposed to recover a senator's son, but when he thought he'd tracked the kidnapper down, instead of a boy, he found a robot, which he assumed was a decoy of some kind. It was actually the senator's adopted son. Which El Sabueso only learned after blowing up the kidnapper's base with the robot still inside.
