Kitty Norville/YMMV


 * Complete Monster: Carl, by the time of his death in book 4. Also the hunters in book 7, who not only set up a fake reality show for the express purpose of trapping, terrorizing, and murdering a whole slew of supernatural "monsters" (and then televising the results, both from a sense of pride and to show the world "how it's done"), but they include people who shouldn't even be there--harmless psychics like Jeffrey Miles and Tina, an atheist (on the grounds that his convincing people the supernatural doesn't exist helps maintain The Masquerade so the "monsters" can keep living unmolested and plotting against the human world), and another completely human talk show host like Kitty. They also murder completely innocent human techs who were part of the fake show in order to hide their crimes and isolate the victims, and make each of the supernaturals record heartfelt messages to their loved ones which would be played as their final words after they were murdered. And, of course, maliciously enjoyed killing each one of them. Death was far too good for them.
 * Moral Event Horizon: starts out as just violent and possessive, but moves up to sexual assault, rape, and eventually torture. And murder, in the case of poor Jenny.
 * Also, as of book 7 Kitty herself has crossed her own personal line, having, something she swore she'd never do. Considering the fact she came close several times to losing herself in the Wolf and even harming her friends and allies, she may be right to worry.
 * Well,  and she doesn't regret trying to do that. Later, her Wolf side , but she supressed the urge because he didn't deserve it. And in an earlier book she offered to turn a family member, so her own personal line is a bit blurry. A bit of Angst was natural and expected in the situation in book 7, but it's nowhere near a What the Hell Hero moment.
 * Never said it was. The implication was that if, in order to stop the forces of darkness/chaos, Kitty is forced to keep doing such things, eventually she may fully cross the line and have a true What the Hell Hero moment. She probably won't do so since she's the Hero, but it seems to this troper that the author is likely to address the issue and have some Angst regarding it.
 * Romantic Plot Tumor: Kitty Takes a Holiday is ostensibly about fighting a curse, but the major plot thread running through the book is  It even
 * There is a bit more to it than that, since facing said Anticlimax Boss and obtaining info about the skinwalker is essential to clearing Cormac's name, the face-off with the skinwalker is actually quite intense and climactic, and helping Ben deal with is a dramatic and well-written character arc in its own right. But the romance does take up more room in the plot than it probably should.
 * Tear Jerker: Right from the beginning the death of T.J. is this, as is Jenny in book 4, but the slew of deaths in House of Horrors ramp it up to eleven. Especially traumatic are the deaths of, Gemma, and.
 * Unfortunate Implications: One of the supernaturals killed in Kitty's House of Horrors is black--and he is the first to die, other than Dorian. Also, the suggestion that Balthasar attempts to seduce and sacrifice Kitty either because he's male (we never see a female lycanthrope do such a thing) or because he's a lycanthrope (read: furry) is disturbing to say the least. The seduction and sacrifice scenes are also a little too S&M for comfort (and this is lampshaded by Kitty herself).
 * The Woobie: Estelle in book 1, Jenny in book 4. The latter is especially poignant as a What Could Have Been for Kitty herself.
