History Characters / KillerFrequency

* TheHeroDies: [[spoiler:If you don't find Peggy's eighth birthday card from Marie, she'll be killed just before Forrest is (unless you saved every single caller prior, in which case the police will arrive just in time to save Forrest alone). In the absolute worst ending (where every single caller dies), you don't even get the chance to save her- Marie will order Henry to kill you while telling you that she's gonna murder Peggy next.]]

* ForTheEvulz: This very likely is the one and only reason he bothered locking Murphy in a dumpster instead of just simply killing him with a knife.

* TheGadfly: While his constant attempts to advertise himself on Forrest's station could come off as being overzealous more than anything else, the fact that he takes the time to fake accents long enough to get Forrest to drop his guard, and is even ''stifling laughter'' comes his last call, really gives off the impression that he's just as much doing it to actively get a rise out of Forrest as he is trying to get free coverage. This doesn't make it any ''less'' egregious than it already is, considering that people's lives are dependent on Forrest being able to take their calls throughout the night.

* ArbitrarySkepticism: Averted. He genuinely doesn't think the Whistling Man is back, but it doesn't take him long to realize that Forrest isn't kidding that the "prankster" hunting him is genuinely violent and dangerous.

* JerkWithAHeartOfGold: He's not happy to realize Laurie has been replaced by The Scream, and lets Forrest know, and thinks he's being pranked so is even more grumpy. Apart from that, he isn't dumb, and genuinely thanks Forrest if saved.

* {{Jerkass}}: It really says a lot that Peggy is willing to put up with Forrest's antics, even at his [[BlackComedy absolute worst]], but can't even stand hearing Teddy talk. It's definitely saying something when Forrest, even before actually speaking to him, calls him a "Grade-a asshole" from hearing his tape.

* PoliticallyIncorrectVillain: He despises Linda for not being American, hinting at some possible racial and/or ethnic prejudice. He's also implied to be misogynistic, as he calls Peggy unstable the minute she expresses disdain for him, but he doesn't say a word to Forrest when he gets equally critical.

* PsychoKnifeNut: Their preferred method of killing is with a knife, however Marie will use a chainsaw to kill Eugene and Henry presumably at one point uses bombs to try and kill Chuck.

* SuperStrength: Henry is strong enough to lift and throw a couch like it's nothing, beat the shit out of an adult man, and lift Forrest up by the neck. Marie, if she is the one that kills Clive, is strong enough to strangle a man to death with her bare hands.

* CruelAndUnusualDeath: If Leslie's reaction to seeing Sheriff Mathews' corpse and her cutting off Jimmy's face are any indication, her victims tend to not look pretty after she's done with him.

* VillainousMotherAndSonDuo: They have this relationship, being a pair of serial killers stalking the town of Gallows Creek.

* EvenEvilHasLovedOnes: Her entire rampage is spurred on by the death of her boyfriend, and during the GoldenEnding she urges Henry to run after the police show up at both the gym and the radio station.

* MessyHair: Assuming the hair isn't a part of the mask, his hair is curly and uncombed.

* PsychoKnifeNut: Is a [[AxCrazy murderous]] SerialKiller that [[CruelAndUnusualDeath brutally]] slaughters his victims with a knife.

* SinisterWhistling: Much like the infamous killer he's impersonating, Henry will whistle whenever he's either chasing someone or is about to kill someone.
* SuperStrength: Henry is almost unnaturally strong, being able to easily throw a couch and lift Forrest Nash up with just one hand.
* VillainousMotherSonDuo: He and his mother are the killers terrorizing Gallows Creek.
