* AdventurerOutfit: He is rarely seen outside of his dracology clothes.
* AntiHero: Type III.
* AwesomenessByAnalysis: He sees the world as an endless list of numbers and factors, and he can therefore calculate the probability of any given occurrence when he concentrates.
* AppliedPhlebotinum: Chips the Intrusively Mantic Phone, whom Mediochre can use to send out or block pretty-much any electromagnetic signal he wishes to.

* ByronicHero
* CampStraight
* CelibateEccentricGenius: The former two are due to his being 400 years old in a 15-year-old body. The latter’s natural.

* DefectiveDetective: He’s not the most emotionally stable of slayer-catchers.

* IndyPloy: His default Plan B, it would seem.
** XanatosSpeedChess

* TheProfessor
* ReallySevenHundredYearsOld: He’s around 400.
* SavedByTheAwesome: Why Queen MAB lets him have so much free reign.
* SelfMutilationDemonstration: When he wants to scare an opponent into giving up, such as when he blows off his own finger in front of Antler’s goons.

!!Charlotte Johnson
The viewpoint character, at least at first. An ordinary girl, recently moved to Scotland from America, who forces her way into Mediochre’s world after he almost gets her killed.
* ActionGirl: Not exactly, but she’s better than Mediochre at least.
* TheApprentice: Eventually becomes Mediochre's.
* AudienceSurrogate: The only non-magical teenager in a series aimed at (presumably) non-magical teenagers.
* DeadpanSnarker: Gives Mediochre a run for his money.
* FishOutOfWater: A mantically-unaware American in Mantically Aware Britain.
* HairOfGoldHeartOfGold: She’s the least morally ambiguous of the four, and she’s blonde.
* TheHeart
* JumpedAtTheCall: And ''kept'' jumping until The Call gave up and let her come along.
* OrdinaryHighSchoolStudent
* SupportingProtagonist: She gets the most pagetime and the series starts off (and largely remains) from her point of view, but it ain’t called "The Good, the Bad and the Charlotte", now, is it?
* TheTeamNormal: Mediochre has a HealingFactor and AwesomenessByAnalysis, Dhampinella has SuperStrength and SuperSpeed, and Joseph is a GeniusBruiser with ImprobableAimingSkills. Charlotte mostly hangs around being sarcastic.
* TookALevelInBadass: Over the course of the first book.
* UnfazedEveryman: Or rather, Unfazed Everygirl.
* TheWatson

!!Professor Joseph Carrion, [=PhD=]
A cynical, gun-loving professor of [[TheUndead zontanecrology]], intensely loyal to Mediochre and revealed in the ChristmasEpisode to be his godson.
* ActionHero
* AntiHero: Also a Type III, but for different reasons to Mediochre.
* {{Badass}}: One of the biggest in the series. Let’s count the ways:
** BadassBookworm: A former TeenGenius and TheProfessor by some point in his twenties, but he’s been able to hold his own in a fight against stronger opponents since he was eighteen.
** BadassNormal: Is a better fighter than most of the people with magic powers or a HealingFactor, and part of his job requires him, as a normal human being, to subdue undead monstrosities.
** BadassLongcoat: In black, of course. It holds some of his guns.
** BadassTeacher: He knows Dhampinella can handle herself, but it’s pretty clear it would be bad idea to attack any of his students.
* BoisterousBruiser: Shades of this.
* TheChampion: For Mediochre.
* DarkIsNotEvil: Strongly associated with guns, violence and the colour black, but he’s arguably a nicer guy than anyone else in the party.
* DepletedPhlebotinumShells: His guns run the gamut.
* FromDressToDressing: Seems to be used to doing this.
* GoodIsNotNice
* TheGunslinger
* HotBlooded: Less than Mediochre, but it’s there.
* ImprobableAge: He's somewhere in his twenties, but he's already a Professor. We find out in ''[[ChristmasEpisode Born to Raise the Sons of Earth]]'' that he was a ChildProdigy and wrote a thesis at seventeen.
* ImprobableAimingSkills: They’re his CharlesAtlasSuperpower.
* InterdisciplinarySleuth: A zontanecrology professor who catches undead-slayers.
* MadeOfIron: His other CharlesAtlasSuperpower. He can basically shrug off bulletwounds.
* NamesToRunAwayFromReallyFast: Carrion. It’s what he’ll reduce you to if he has to.
* OccultDetective
* OvershadowedByAwesome: He’s Mediochre’s godson, Mad Lex’s apprentice and his family has a history of great scientists. He’s felt this way since he was a kid.
* PoisonousFriend: To Mediochre.
* PopCulturedBadass: A fan of Series/TheATeam and Music/TheBeatles, among others.
* PragmaticHero: In contrast to Mediochre's attempted idealism.
* SelfStitching: He’s clearly practiced.
* TeenGenius: Used to be one.

Joseph’s Dhampir apprentice.
* ActionGirl: Heck yes.
* TheApprentice
* {{Badass}}: Oh my, yes.
* BadassLongcoat: Which she only [[TheCoatsAreOff removes]] when she wants to really let loose with the violence.
* BoyishShortHair: Dhampinella has a bob haircut, presumably so that it stays out of her way when she's fighting.
* TheChampion: For Joseph.
* CuteBruiser: A little bit.
* CuteMonsterGirl: But only in a [[StoicWoobie woobieish]] way.
* DarkAndTroubledPast: Her father was not a very nice man, even by Vampire standards. Her mother left when she was very young, and her father was eventually murdered.
* DarkIsNotEvil
* {{Dhampir}}
* EmotionlessGirl: See under TheSpock.
* HalfHumanHybrid: Her father was a Vampire, her mother a human.
** HumanMomNonhumanDad
* {{Ladyella}}: Her name roughly means Little Dhampir Girl.
* LightningBruiser
* MadeOfIron: All Dhampir are, it would seem.
** GoodThingYouCanHeal: Used a bit as a meatshield.
* NotSoStoic: In the second book, she gets worried about her sister, and angry about Guinevere Spencer. The latter even provokes her to mildly ''[[PrecisionFStrike swear]]''.
* OneManArmy: Well, One Dhampir Army, technically.
* OOCIsSeriousBusiness: Whenever she goes NotSoStoic.
* ParentalAbandonment
** MissingMom: Her mother left when she was very young.
** DisappearedDad: Her father has a better excuse – he was murdered by a slayer.
* TheQuietOne: Says almost nothing unless addressed directly.
* RelativeButton: She becomes NotSoStoic whenever her sister is involved.
* SignificantGreenEyedRedhead: Her eyes are very green, and her hair is reddish. It adds to the ethereal feel.
* TheSpock: Possibly. Dhampir may just show their emotions in a different way to humans.
* TheStoic: Again, possibly.
* SuperSpeed
* SuperStrength
* TerseTalker
* TranquilFury: If she ever feels any emotion at all, it’s probably this.
* UncannyValley: Tends to invoke this in people.
* YouKilledMyFather: In backstory, this was how her first case alongside Joseph began.

Mediochre’s pet mouse, which mostly lives in his jacket. Was apparently a present from Joseph.
* ChekhovsGunman: Odd but true. The mouse, of all people, comes in useful half way through the first book.
* NiceMice
* SquirrelsInMyPants: Averted. Mediochre barely notices the fact he has a mouse crawling around in his clothes.
* TeamPet

[[folder: The [=MABGov=]]]

* BadassBureaucrat
* BerserkButton: The one time he [[OOCIsSeriousBusiness loses his cool]] is when Fervour attempts a coup.

* HiredForTheirLooks: Defied. Queen MAB thinks that whoever started that rumour clearly doesn't realise the extent to which the sight of Tanner [[FetishRetardant reminds her of work.]]
* ParentheticalSwearing: Tanner can put a surprising amount of meaning into the single syllable "sir".
* RightHandHottie: Tanner is as meticulous over his appearance and fitness as he is over his paperwork.
* SharpDressedMan: See RightHandHottie above.

!!Maccabeus Fervour
The head of the opposition [[spoiler: and eventually of the [=MABGov=].]]
* BadassBureaucrat: Capable of this, but only in his attempts to outdo or discredit Queen MAB.
* CorruptPolitician: Fervour is a bully who is only in politics for the power.
* [[spoiler: TheCoup]]
* MeaningfulName: Fervour implies zealotry, which he seems to be guilty of. Maccabeus was also the name of a revolutionary in Jewish history... whose first name, for added points, was ''[[NamesToRunAwayFromReallyFast Judas]]''.
* [[spoiler: PuppetKing]]: Mediochre believes him to have become this by the end of the second book.
* [[spoiler: TyrantTakesTheHelm]]: By the end of the second book.

* HeartWarmingOrphan: So far as we can tell, her parents are the regular kind of dead.

!!Reverend Archibald Maria "Archie" Elijah
A Vampire contact of Mediochre, who is also a Christian minister and something of a father-figure to Dhampinella.
* BadPowersGoodPeople: He knows how to conduct exorcism (which, in this setting, is a form of necromancy otherwise mostly used by the Humanist Movement). He only ever uses it to save people.
* BigDamnHeroes: He organises a group of exorcists to neutralise the threat of the [[spoiler: undead bacteria]] just in time. Does it again with the Edinburgh Kiss.
* CoolOldGuy
* {{Determinator}}: Just because he's an undead horror with an aversion to everything holy doesn't mean he's gonna stop being a Christian.
* ClassicalMovieVampire: Looks like one. Doesn't act like one.
* FriendlyNeighbourhoodVampire: Taken to extremes.
* GoodShepherd
* MySpeciesDothProtestTooMuch: He's a Vampire. He's also a religious leader.

* TheGroup

* ThemeNaming: They use the names of precious stones for code names.
* UtopiaJustifiesTheMeans: Maybe - see WellIntentionedExtremist below.
* WellIntentionedExtremist: The tempomancer claims that they seek to further human development, although he may have been lying to Joseph at that point. Either way, they are willing to cause death and destruction in the name of their goals.

!!The tempomancer AKA Topaz
Real name unknown. A powerful and enigmatic man who functions as some sort of field agent for The Organisation Which he Represents.

A colleague of the tempomancer who advises Charlotte in secret and claims that the tempomancer is a rogue agent whom he is hunting down. [[spoiler: He’s lying, it seems. He’s actually the tempomancer’s underling.]]
* DoubleReverseQuadrupleAgent: Works for Mediochre, but actually works with the tempomancer, but actually works against the tempomancer for TOWIR. [[spoiler: But actually works for both the tempomancer and TOWIR in accord.]]
* TheDriver: What Mediochre uses him for. He knows every road in the country.

!!Catriona Haulier AKA Obsidian

* YouHaveOutlivedYourUsefulness: She pulls one of these on [[spoiler: Gambit]].

Apparently Obsidian's direct superior.

* EvilIsSexy
* SlouchOfVillainy: She doesn't even just ''slouch''; she ''lounges''.
* WhatTheHellIsThatAccent: It's always something from western continental Europe, but beyond that she seems to like to keep people guessing.
* [[ManOfWealthAndTaste Woman of Wealth and Taste]]

An underling of The Organisation, assigned to keeping alive [[spoiler: the necromancer]].
* KidWithTheLeash: To [[spoiler: the necromancer]].

* GangOfHats: Does being a Vampire count as a Hat?
* GenericEthnicCrimeGang: With the twist that the "ethnicity" here is "''Vampire''".
* RuthlessForeignGangsters: Even if you don't count "undead" as a type of "foreign", several of them ''are'' foreign anyway. And they are ''definitely'' ruthless.

[[TheDon Broodmother]] of the Edinburgh Kiss.
