[[folder: Main characters]]

!!Sam Puckett
->'''Portrayed by''': Creator/JennetteMcCurdy

A character originating from ''Series/{{iCarly}}'', who was part of the main cast. At the end of ''iCarly'', she is seen leaving Seattle and wound up in Los Angeles. She meets Cat in less then stellar circumstances and becomes her roommate, where they start a babysitting business.
* ActionGirl: Won't hesitate to get into a scrap.
* BerserkButton: Don't call her "sweet"...unless you're Cat.
** When Dice got kidnapped, she was SO vulnerable, probably for the first time in her life.
** Apparently, cutting her pizza into rectangles or any shape besides triangle.
* BigDamnHeroes: Saves Cat from getting killed in a garbage truck.
* BigEater: One time Cat goes through her handphone contacts and gets a shock at how many of them are eating places.
* BuxomIsBetter: Nickelodeon finally gave in to the inevitable and stopped trying to hide Jennette's assets.
* CardCarryingVillain: In episode 5 she proudly proclaims that she has no heart.
* CuteBruiser: Every bit as much as in her previous show, taking down full grown men easily and ripping parking meters out of the ground when angry.
* DeadpanSnarker
* EvenEvilHasStandards: Even she is horrified at the rival babysitters using children the way they do in "[=#ToddlerClimbing=]."
* HatesBeingTouched: Not a fan of Cat's insistent hugging of her, but she manages to tolerate it.
* HypercompetentSidekick: Downplayed, as she herself is careless and there are times Cat is the responsible one.
* JerkWithAHeartOfGold
* KarmaHoudini: Returns in full force from ''iCarly''. Fan reaction is just as divided as it was in 2007.
* MasculineGirlFeminineBoy: Masculine to Dice's feminine.
* SuspiciouslySimilarSubstitute: Basically for Jade, having the same general personality as her (albeit less palbable) that serves as a contrasting foil to Cat.
* TheLadette
* TheMcCoy
* TokenEvilTeammate: Much like she was in ''iCarly.''
* TomboyAndGirlyGirl: Tomboy to Cat's Girly Girl.
* TookALevelInKindness: Only towards Cat though, as Dice learned.
* UnsympatheticComedyProtagonist
* WeaponOfChoice: If this and ''iCarly'' are anything to go by, Sam is fond of using a sock filled with dried butter as an improvised weapon.
* YouCantGoHomeAgain: A mild example; She can somehow return to Seattle, but her best friend left, so now she doesn't have ''iCarly'' anymore, all of which she dedicated her life to. She also broke up with Freddie, so Sam pretty much has nothing left to do with her life, so she settles in LA with Cat to start a babysitting service and make ends meet.

!!Cat Valentine
->'''Portrayed by''': Music/ArianaGrande
A character originating from ''Series/{{Victorious}}'' as part of the main cast. Near the end of ''Victorious'', her parents move to help take care of her insane brother, so she ends up moving in with her grandmother. She meets Sam at the time the series starts and when her grandmother chooses to move into a retirement home, she and Sam become room-mates and they start a babysitting business together to help pay for their rent.
* ACupAngst:
-->'''Cat''': When I say Aybra Kadaybra--
-->'''Sam''': Wait, I thought you wanted me to stop making fun of your A-Bra.
-->''(Cat crosses her arms defensively over her chest and looks hurt)''
** Unfortunately, Ariana Grande has an A-Cup size in real life (which is what makes the joke funny).
* {{Adorkable}}
* BewareTheNiceOnes: She's a sweetheart most of the time but if you make her lose her temper it's a scary thing. Particularly epic was her unloading on the creepy dad in "[=#DollSitting=]".
* CloudCuckoolander
* CuteButCacophonic: Cat's voice is much more high-pitched and baby-ish than it was in ''Series/{{Victorious}}''.
* CuteClumsyGirl: Seems to have evolved into this.
* TheCutie
* TheDitz: But she's not necessarily BookDumb.
* FriendToAllChildren: Naturally.
* GenkiGirl
* TheKirk
* MakesJustAsMuchSenseInContext: In "[=#BrainCrush=]" Cat does a one-girl show as, and about, ''Baberaham Lincoln'' (Abraham Lincoln if he was female). With a [[FakeBrit British accent]].
* {{Malaproper}}: A RunningGag is that she calls things wrong.
* MoralityPet: Like [[Series/ICarly Carly]] did, Cat serves as an anchor to keep Sam on the side of good, more or less.
* MsFanservice: A {{Moe}} with long legs and short skirts.
** Her Halloween outfit displays some abs.
** She also displays her pins while playing Honest Abe...ss (complete with beard and whiskers. Strangely, this doesn't come off as FanDisservice).
* NiceGirl
* NoSenseOfPersonalSpace: Really likes to be close to Sam, also likes to hug her, much to [[HatesBeingTouched Sam's annoyance.]]
* TheScream: Has been known to let out a bloodcurdling scream in several episodes.
* ShesGotLegs: Ironically, she's actually ''shorter'' than Sam ([[TeensAreShort not exactly a]] StatuesqueStunner herself).
* SweaterGirl
* SweetTooth: Not nearly as bad as ''Series/{{Victorious}},'' but it's still there.
* TheTease: Is she ever...
* TomboyAndGirlyGirl: Girly Girl to Sam's Tomboy.
* TookALevelInJerkass: She had been showing signs of it with her treatment of Dice and episodes like "[=#MagicATM=]"; it's been set in stone in "[=#KnockOut=]" when she tried to hit a 5 year old just to prove Sam wrong. Even Sam hasn't approved of some of her actions.

->'''Portrayed by''': Cameron Ocasio

Another member of the apartment building the duo live in. Dice is a benefactor of sorts who gives the girls random items he comes across for a price, and occasionally helps them in their adventures.
* ButtMonkey
* {{Expy}}: of [[Series/ShakeItUp Deuce]], but younger.
** He can also be considered an expy of a younger [[Series/ICarly Freddie Benson]]. Like Freddie, he is often the butt of Sam's jokes and antics.
* {{Fanboy}}: Of Series/{{iCarly}}, judging by his reaction to Sam in "#Pilot."
* FunnyAfro: Sometimes under a NiceHat.
* OnlySaneMan: Between the PowerTrio of himself, Sam and Cat.
* ShorterMeansSmarter
* TheSpock
* TheTeamBenefactor
* TokenGoodTeammate: If anything, he doesn't like stealing or doing anything illegal.


[[folder: Recurring Characters]]

->'''Portrayed by''': Maree Cheatham

Cat's grandmother and former owner of the apartment the two protagonists live in. After a bad incident involving some children, Nona moved to Elderly Acres, an old folks home several blocks from the apartment.
* CoolOldLady
* DeadpanSnarker
* FieryRedHead
* InnocentlyInsensitive: She gave a retired pilot a lollipop as a gesture of kindness, forgetting he lost his tongue in a crash landing.
* OnlySaneWoman
* TotallyRadical: "[=#TheBritBrats=]" shows her trying to talk like this. It is both cringe-inducing and hilarious.

!!Geau Merr "Goomer"
->'''Portrayed by''': Zoran Korach

An MMA fighter Dice became the manager of in "[=#NewGoat=]". He's not all there mentally, but is shown to be a competent fighter.
* AmbiguousDisorder: It's up to the audience to choose whether he's just stupid or has an actual disorder.
* BerserkButton: Don't insult Dice, and ''really'' don't insult Dice's beautiful, beautiful hair.
* CrouchingMoronHiddenBadass: Not so hidden, since he's outright stated in his first appearance to fight for money, but otherwise fits the trope.
** It is however implied that he's not a good fighter, as his previous manager before Dice gave him up for a pretty low price.
*** Actually he was given up for being too stupid; Goomer actually says it too.
*** He was also capable of taking down a group of street thugs who were stealing his mother's purse.
* TheDitz: The guy makes ''Cat'' look like Creator/StephenFry.
* DumbMuscle: He may very well be mentally handicapped.
* GenreSavvy: Of all people, Goomer recognized that Gwen and Ruby were the ones who stole Cat's bibble just to turn her against Sam. It's even more amazing, yet made stranger by the fact that Goomer never even met Gwen and Ruby, and had knowledge of the events of "[=#TheBritBrats=]," which he clearly wasn't a part of.
** In "[=#BlueDogSoda=], he was smart enough to realize that in order to sell bootleg soda, the heroes would have to keep up with the supply and demand as well as letting the public know about their soda while making sure the law enforcement doesn't. Sam and Cat were understandably shocked by what he said.
* HappilyAdopted: By an African American Woman.
* HisNameReallyIsBarkeep: Up until "[=#MommaGoomer=]," it seemed like Goomer was a nickname. Turns out his last name is Merr, and his first name is Geau (his father was French).

[[folder: Minor Characters]]
