Even Evil Has Standards: The vampire cheerleaders themselves who follow a very strict set of rules in regards to feeding. And if you violate these standards, then Lori will have to have a word with you.
Its mostly Pragmatic Villainy type of standards, but applies even to seemingly minor things like not being unnecessarily mean to Leonard.
Immortal Immaturity: Justified as Lori's the only one who's been a vampire for more than a couple of years.
Corrupt the Cutie: Mostly all of volume one as she discovers more of her powers. Vol 2 sees her rein it in a bit, probably out out penance for costing her school the big game.
Easily Forgiven: She feeds on her school football team, making them too weak to play in the big game. Heather quickly comes up with a plan to drain the opposing team so they're on equal ground. Once the deed is done, Lori forgives her.
Leonard doesn't seem to blame her for the fact that he was brainwashed by Vampire Cheerleaders, since is his words: "You do what you have to for a little BC". He also admits to "kinda enjoying it" (other than the trunk).
Transhuman Treachery: Though she is chided twice for being bloodthirsty, she is somewhat kind to her human friend, and mostly sticks to the rules. Why she is slightly horrified upon seeing Leonard stuck in a car trunk for lengthy travel, she doesn't try to push the issue with Lori.
Compulsory School Age: Subverted. She has been returning to school every 20 years or so since at least 1892 of her own volition, apparently in a quest for the perfect senior year.
Hypocrite: While is very eager to get her revenge at Bianca for raping her, its strongly implied she used Leonard for sex when he was brainwashed into being her thrall. For double Squick he is a high school teenager, and she is over 100 years old vampire.
Coitus Ensues: Between her and Leonard, while they're at the Lemurian hotsprings, during the "Adventures in Space... and Time?!" arc in Vol.4. In her own words, "she was horny and they were already naked, so why not?"
Double Entendre: She's become fond of these, where Leonard's concerned and as a way of getting under Katie's fur.
Katie: (at Suki) "I know where your weak point is, vampire."
Heroic BSOD: Has one seeing Delenn'us, in which she remembers Cressida Harrow eating her liver again and again (it continually regenerated, making Suki a "renewable resource"). Giving Cressida's threat to make Suki into a "Suki-yaki" Harsher in Hindsight.
Too Dumb to Live: In Vol 2 when the snooty rivals manage to outwit the squad in retaliation for taking their training time, she suggest biting and turning them. Zoe has to remind her that would unleash a squad of unrestrained vampires loose in the building, exposing themselves in the process.
Crazy-Prepared: Up till Plan BC, he was actully doing pretty good against the girls. Even having chugged Listerine and gorged himself on garlic event they tried to bite him. Lori tried. It didn't work out well for her.
Stephanie, Charlotte and Katie doing their "nerd burlesque" for him might have him realize they're not the only "sex goddesses" around, especially if his reaction to Katie's "Slave Leia" routine is a sign.
Worst thing they do to him is to have him travel in trunk of their car. Other than that, Suki is meaniest to him (or to anyone for that matter), and worst thing she does is... steal his comics - which is enough to piss off Lori enough to hit her until she gives them back. He wouldn't be worse off than whipped boyfriend would, if it wasn't for the fact that he didn't choose to live like that: he was .
Tragic Bigot: What happened to her parents definitely contributed to her original murderous attitude towards cryptids of all kinds.
Van Helsing Hate Crime: She who believes all cryptids are evil roughly stemming what happened to her parents. Things gets complicated when her sister is turned into a werewolf and the newest member of their team is revealed to be a Dhampyr.
Emergency Transformation: Somewhat, she gets infected with lycanthropy but Charlotte manages to use a spell so she doesn't become a mindless creature.
Idiot Hair: She has one sticking up in the back. Reflects her tendancy to act without thinking.
The Load: Initially in the first chapter, as she didn't have as much combat experience as Steph or Charlotte and mostly just carried around equipment. Steph insisted on bringing her on the cryptid hunts anyway. The second big case of which she wound up wandering off and getting bitten by a werewolf. After she herself became a werewolf, she put her new monster strength to good use.
When Charlotte opens her purse for smelling salts and out come lots of tampons, Katie snarks "Heavy flow month?" Stephanie tells her "It's the whole team's supply, you dingbat!" before giving her a fist upside the head.
Obstructive Bureaucrat: With some overlap of Too Dumb to Live - seeing as she contacted offices in Washington to confirm that K'AAN'NGUA is protected by the Endangered Species Act of 1973. Effectively making it impossible for the military to do anything to stop it. You know, despite the fact that it will probably kill everyone.
Bond Villain Stupidity: Of her own accord as she admits she before she would just outright eat her victims in the past, but now likes to savor them nice and slow. A good thing for Lori as it allows her to form a plan of escape.
Offscreen Villainy: The author ran out of time to draw the epilogue for the volume set. So instead wrote what became of Bianca's servant in simple text formet on the webcomic. However if you're reading from the volume, you might be understandably confused why the servant is suddenly dead.
Four-Star Badass: Apparently ready to lead an attack on K'aan'ngua from the front lines. His moment of glory gets stolen by O'Keefe when she gets the President to order him to retreat. He gets even by having the PMS team cleared of their community service much to O'Keefe's chagrin.
Reasonable Authority Figure: He is put in charge the incident in Volume 2 comes off sympathetic to the PMS crew, and most definately does not like O'Keefe's presence and interfeerence.
