!!Arthur "Art" Mathews
* AccidentalPervert: Is actually this about 90% of the time.
* {{Adorkable}}
* AllMenArePerverts: Not as much or as loudly as Pip, though.
* ButtMonkey
* DeadpanSnarker
* OnlySaneMan: When he's not succumbing to NotSoAboveItAll tendencies.
* OnlyKnownByTheirNickname: His actual name is [[http://www.collectedcurios.com/sequentialart.php?s=1003 Arthur Mathews]], but most people just call him Art.
* TokenHuman
* WalkingTechbane: Technology ''explodes'' in his presence.

!!Kathleen "Kat" Vance
* BewareTheNiceOnes
* BrainyBrunette: Colorations of her depict her with light brown fur/hair.
* CatGirl: Somewhat less humanoid than the classic Japanese version, but still essentially a woman with cat ears and tail.
* CovertPervert
* DeadpanSnarker
** CatsAreSnarkers
* FurryReminder: Generally she acts like a human, but she ''does'' have a problem resisting dangled yarn. [[http://www.collectedcurios.com/sequentialart.php?s=889 And she once brought Art a dead bird as a 'gift'.]]
* GamerChick: Loves her StreetFighter.
* GenkiGirl: At times.
* HardDrinkingPartyGirl: Played with. Only seen to drink on holidays, and when she does, she inevitably ends up with a horrendous hangover.
* PluckyGirl
* {{Tsundere}}: She's rather moody but generally nice.

!!Phillip "Pip" [=McGraw=]
* AllMenArePerverts: So much so that he apparently has [[http://jollyjack.deviantart.com/art/2nd-Character-Q-and-A-431089129 hidden cameras in the house]] for when the sexual tension between Art and Kat finally reaches its breaking point.
* BreakTheCutie: [[spoiler: What Hilary did to him]].
* ButtMonkey
* EverythingsBetterWithPenguins
* FurryReminder: Pip has one of these when Kat is chastising him for not wanting to feed Leonard. He points out that his natural paternal instincts do make him want to feed Leonard, but he's fighting it because birds feed their young by regurgitating food into their mouths. Pip has another reminder when it comes up that he has to "double flush" when he poops because "birds can't chew".
* JerkAss
** JerkWithAHeartOfGold: At times; at other times he's almost the TokenEvilTeammate.
--> '''Pip:'''(referring to the [[TheBox deadly button in that will kill someone in exchange for a reward if he presses it]])"I even held it down".
* NerdGlasses
* PitySex: Well, partly.
* SarcasmBlind: One time when he asks Art if the latter has a huge sum of money to cover his [=eBuy=] purchase, Art nonchalantly says he has tons under his bed, and Pip tore Art's mattress to find out:
--> '''Pip''': [[http://www.collectedcurios.com/sequentialart.php?s=54 I see naught but lint and springs...]]\\
'''Art''': Sarcasm, Pip, '''sarcasm'''!

* CloudCuckoolander
* ColourfulThemeNaming: With her sisters.
* TheCutie: Along with her sisters.
* FieryRedhead
* FunetikAksent: To reflect a general simple-mindedness.
* GadgeteerGenius: Even without her sisters, she's capable of devising spectacular gadgets.
* GeniusDitz
* '''GenkiGirl'''
* HiveMind: With her sisters. Their connection is the reason why Scarlet is such a ditz early on.
* InnocentFanserviceGirl
* LeetLingo: Her name is spelled 5C4RL37.
* SesquipedalianLoquaciousness: Originally a once-in-a-while gag to show off her HiddenDepths. It turns out to be an aspect of the squirrel hivemind she belongs to.

!!Violet, Amber and Jade
* ColourfulThemeNaming: With Scarlet.
* GadgeteerGenius
* {{Hikikomori}}: Due to OZBASIC making them agoraphobic.
* HiveMind
* IdiotHair: Amber's ahoge.
* LeetLingo: Their names as spelled are [=V10L37=], 4M83R, and [=J4D3=].
* {{Mad Scientist}}s
* OutOfFocus: Even after they find a work-around for their fear of open spaces, they're rarely featured.
* {{Satellite Character}}: They're practically never seen apart. Justified: their minds work better when they're within (telepathic? radio?) range of each other.
* WeaksauceWeakness: Severe agoraphobia, [[InvokedTrope forced upon them]] to keep them from running away like Scarlet did. They also have to stay close to each other or end up half-wits until they rejoin the hive.
* SpeakInUnison: They do this when their HiveMind intelligence is at its zenith, since they are thinking on the exact same wavelengths and thus reach the same conclusions.

!!Leonard
* TheChewToy: Bordering on CosmicPlaything.
* CoolPet
* EverythingsBetterWithPlatypi
* TeamPet

!!Vanity
* AuraVision
* ExperimentedInCollege: Implied. During a fan [[http://jollyjack.deviantart.com/art/2nd-Character-Q-and-A-431089129 Q&A with various Jolly Jack characters]] when asked if there she was more than friends with Kat she shrugged the question off answering "It was college."
* ISeeDeadPeople: She's friends with the ghost of Creator/BramStoker.
* NightmareFetishist
* OfCorsetsSexy: Her primary outfit consists of a black leather corset-style bodice and skinny jeans.
* PerkyGoth: She gives most of the credit to caffeine.

!!Jack
* AffablyEvil: He doesn't bear anybody ill will, it's just that their suffering amuses him.
* AxCrazy
* EvilIsHammy
* HarmlessVillain
** NotSoHarmlessVillain: He was just warming up.
* TheNapoleon

!!Denizens
* AdorableEvilMinions: While following Jack.
* DarkIsNotEvil
* HeelFaceTurn: Like ants, they have to have a master. Kat and Art don't want to be that master (and they ''really'' don't want Pip or Scarlet to be that master).
* LivingShadow
* MundaneUtility: What they're used for.

!!OZBASIC
* AIIsACrapShoot
* {{Expy}}: Of [[{{VideoGame/Portal}} GLaDOS]].

!!Hilary
* AlphaBitch
* AttentionWhore: Pretty much her motivation for 99% of everything she does. In fact, the reason she hates Kat [[spoiler: is because they both had the same Pink Pony lunch box as little girls, and Hilary was afraid that Kat would take attention and popularity away from her because of it]].
* BitchInSheepsClothing
* BleachedUnderpants: Her early career in... films... is an OldShame.
* [[spoiler:BreakTheHaughty: Losing her job.]]
* DefrostingIceQueen: [[spoiler:Subverted. Her seeming affection to Pip was just a ruse and she's still just as horrible as before.]]
* DisproportionateRetribution: Why does she hate Kat so much? [[spoiler:She had the same Pink Pony lunchbox as Hilary when they were both kids.]]
* EvilRedhead: Colorations depict her with red hair.
* HairRaisingHare: She may be attractive, but she ''revels'' in the misery of others.
* HelloNurse
* [[spoiler:JerkWithAHeartOfJerk]]
* SexForSolace: [[spoiler: Averted.]]

!!Mr. Jackson
* AllMenArePerverts
* AuthorAvatar
* TheHedonist
* RidiculouslyCuteCritter: He's a hamster.

!!Helga
* BuxomIsBetter
* MsFanservice: To the point that Mr. Jackson once orders her to undress in camera to boost site viewing.
* {{Meganekko}}
* TheQuietOne - or is it TheVoiceless?
* SatelliteCharacter: To Mr Jackson.

!! Mr. Thumbless
* {{Expy}}: Of Mr. Tumbness.
* {{Squick}}: In-universe, he literally has no thumbs, but carries the severed digits around and even tosses them at the [[ItMakesSenseInContext flying gorilla guards]].

!! Ms. B
* EvilIsPetty: The reason she put the land of Narni-Narni-Nar-Nar in eternal winter is so she would have an excuse ''to wear fur-lined robes''.
* {{Expy}}: Of the White Witch of Narnia.
* {{Squick}}: The power of the sun didn't ''quite'' repair her face correctly.

!! King Liam
* {{Expy}}: of Aslan.
* NakedPeopleAreFunny
* TheGoodKing: Certainly seems to have the attitude.
* MrFanservice: King Liam is handsome, built like a brick house, and is ALWAYS naked.
* WalkingShirtlessScene: Comes with being naked for ALL your on-panel time.

!! Rebecca Mace
* CargoShip: With Vanessa...
* ICallItVera: ...Who is her personal dressmaker dummy.
* ThisIsUnforgivable: Whatever it is that Pip and Art did to her, she finds it so beyond forgiveness.
--> ''(Upon seeing Art again after presumably a very long time)'' '''MURDERER!'''
* YourMakeupIsRunning: To show how messed up she became after losing 'Vanessa', she's seen with her eyeshadow smeared all around her eyes.
