* ArcFatigue: Some critics have applied this to the Black Lamp Society and Samhain arc. Possibly lampshaded in ''Super Sidekick Sleepover Slaughter'':
-->'''Cassie:''' "I don't know about you, Vlad, but I'm getting really bored with this black flower crap already."
-->'''Vlad:''' "Yes. I liked our [[MonsterOfTheWeek old bad guys]] better."
* CompleteMonster:
** The BigBad is Akakios, AKA [[spoiler: Samhain]]. At first he is a man with LaserGuidedAmnesia and a DarkAndTroubledPast who is an [[spoiler: ally and later lover of heroine Cassandra Hack]]. After a series of events, however, it is revealed that [[spoiler: Samhain]] is the original "slasher," Akakios, founder of the evil Black Lamp Society. Regaining his memories and true personality, Akakios is disgusted by his [[spoiler: former self's feelings for Cassandra, reasoning he could have taken her any time "whether she wanted it or not."]] Akakios forges the undead slashers into a fighting force and systematically kidnaps or kills everyone Cassie loved, purging the upper echelons of the Black Lamp Society [[EvilerThanThou for being "too nice," despite their own atrocities.]] Akakios plans to spread the slasher disease, turning innocent humans all over the globe into murderous monsters.
** For a slasher example, there's Ashley Guthrie. While [[LaughablyEvil admittedly amusing]] here and there, he's still a [[EnfantTerrible child]] {{sociopath}} who, even before he became a member of TheUndead, did things like strangle a litter of kittens to death (he was annoyed his cat was spending so much time with them) before caving his baby brother's skull in (he was annoyed he was always playing with his toys). After becoming a slasher, his first acts were to cause his father to commit suicide and drive his mother insane. His very first appearance has him [[WouldHurtAChild killing a little girl]] in a dream (similar to [[Franchise/ANightmareOnElmStreet Freddy Krueger]]).
** [[MorallyAmbiguousDoctorate Dr.]] [[MadScientist Andrew Rodin]] stands out in the franchise by virtue of not even being a Slasher, just a normal human. The admittedly {{sadist}}ic Rodin is the most vile human member of the Black Lamp society, using his scientific genius to create women for the sole purpose of being sex slaves, which often end up abused. He creates other species for the sole purpose of killing others and brutally slaughters a co-worker when she objects.
* CrossesTheLineTwice: The [=RapeVan=].
* EnsembleDarkhorse: Pooch and Libby Lochs.
* EvilIsSexy: Acid Angel, who really uses it to her advantage.
** Subverted with Butterface. She has a hot body, but an apparently horrific looking face.
* FoeYay: Cassie and BombQueen. [[FetishFuel Oh lawdy...]]
* FridgeHorror: The only major characters who initially get killed by Akakios's mass attack on Cassie's friends are Chris and Lisa. Who got murdered by Dr. Gross. The guy who specialises in long and sadistic physical and mental torture...
* NightmareFuel: [[http://hackslash.wikia.com/wiki/Slasher?file=Slashers.jpg Here]] are some of the slashers.
** The Stillborn. Just what the hell IS that thing?
* RecycledScript: "Super Sidekick Sleepover Slaughter" was recycled from a rejected pitch for a slasher-movie parody miniseries set in the MarvelUniverse.
* {{Squick}}: [[ExplosiveBreeder Mother Leeds]] from ''The Living Corpse'' crossover.
** When Taber threatens to kill himself with a shotgun in ''Something's Fishy'', Mary Shelley Lovecraft disarms him by sprouting another tentacle... from ''between her legs''.
** The Sundermann brothers (one ''[[FetusTerrible lived inside]]'' the other).
* UglyCute: Pooch. Vlad saw Mother Leeds's children as this, but Cassie and The Living Corpse were just {{squick}}ed out by them.
* TheWoobie: Although Cassie keeps her 'tough bitch' act up for the most part, when something manages to break through her defenses it's almost impossible not to feel for her.
** IronWoobie
