[[folder: W.O.O.H.P.]]

->'''Voiced by:''' Creator/JenniferHale

Samantha "Sam" has long red hair, emerald green eyes and a green catsuit. She's the most intelligent and practical of the group.
* ActionGirl: Often leads the team, displays arguably the best hand-to-hand combat skills, and gets kidnapped least. She's usually the one who takes control over the girls' missions and puts her smarts to use.
* AffectionateNickname: Her friends, mainly Alex, sometimes call her "Sammy."
* AlliterativeName: In one episode, she presents herself as "Samantha Simpson." Okay, they were undercover, but they always use their own names for these situations, so why not?
* BadassAdorable: She's beautiful and deadly at the same time.
* BadassBookworm: The first OP has her expertly using a chemistry kit as Clover and Alex watch her in amazement. While at the same time, she is able to fight off the random villains that the trio encounter just as effectively as her partners. AND she also manages to get and keep excellent grades at school (she's mentioned as being a straight-A student).
* BareYourMidriff: She generally bares her midriff in larger amounts than Clover and Alex, but not as frequently.
* BeautyBrainsAndBrawn: The Brains.
* BewareTheNiceOnes: You do not want to get her angry.
* BlondeBrunetteRedhead: The Redhead.
* BraidsOfAction: Temporarily, during the Gladiator episode.
* BrainwashedAndCrazy: A RunningGag in the show is that she winds up like this on a routine basis.
* DeadpanSnarker
* ExtremeOmnivore: Eats a hot towel while at a sushi restaurant, and seems to enjoy it. However, in her defence, the villains had recently stolen her intelligence with their StupidityInducingAttack, so she at least ''thought'' it was food.
* FirstGrayHair: One episode had Sam finding a gray hair in her head (unusual, considering she's a teenager, but not thoroughly impossible) and she spent much of the rest of the episode worrying about her age and seeming young. The {{Aesop}} of the episode, as delivered by a CoolOldLady: "It's not how old you are, it's how you are being old!"
** Although it ends up being a BrokenAesop. Turns, out it was [[spoiler:BeautyIsNeverTarnished just some gray paint that Sam deduces must have somehow gotten in her hair when she was working on an art project]].
* FreudianTrio: The Superego to Clover's Ego and Alex's Id.
* HollywoodNerd: Played with. She's a bookish and studious girl, but also gorgeous and popular.
* {{Hypocrite}}: One Season 3 episode has her acting like a super neat-freak and constantly nagging the girls to clean up the apartment. At the end of the episode we see her room, which is a dump that shows no signs of ''ever'' having been cleaned. Also in "Evil Heiress", Sam tries to show that she is above materialism, and putting down Alex and Clover for their wants, but by the end of the episode, she is more than happy to suggest a private island and a yacht for her reward for completing their mission.
* IntrepidReporter: The major that Sam pursues as of Season 6.
* TheLeader: Of the levelheaded variety, she's the unofficial leader of the trio.
* NerdsAreSexy: Has this appeal InUniverse and out.
* NiceGirl: She's this if you don't push her buttons.
* OnlyOneName: She's mostly referred to as just "Sam." However, see the AlliterativeName entry above for how this might be subverted.
* OnlySaneWoman: [[DependingOnTheWriter Most of the time.]]
* RapunzelHair: Her hair reaches to her waist.
* RedHeadedHeroine: One of the heroes and has red hair.
* RedheadInGreen: In her spy outfit.
* SignificantGreenEyedRedhead
* TeamMom: She's generally the most mature and responsible of the main three.
* TheSmartGirl
* TheSpock
* TomboyishName: "Samantha" is her real name, but nearly everyone calls her "Sam." Usually the only people who actually call her by her real name are her teachers and occasionally Jerry, while, as mentioned above, Clover and Alex (usually Alex) also sometimes call her "Sammy" (which in itself is kind of tomboyish name).
* TownGirls: The Neither to Clover's Femme and Alex' Butch.
* TVGenius: Some episodes give her shades of this.

->'''Voiced by:''' Andrea Baker

Clover has medium blonde hair, blue eyes and a red catsuit. Probably the show's most stereotypical character, Clover is a shopping addicted, boy crazy, teenage "fashionista".
* ActionGirl: Combines this with ActionFashionista.
* ArchEnemy: Geraldine, and arguably Mandy. Sometimes she has a friendly rivalry with Sam.
* AllergicToRoutine: Clover tends gets bored rather easily. Perhaps this may explain why she has an obsession with boys…
* AmbitionIsEvil: Clover usually tries to get famous. In fact, such a behavior is strongly explicit during the episode "Model Citizens" in which Clover and Mandy compete in a beauty contest. There are many other examples though.
* BadassAdorable
* BalloonBelly: She gets pretty fat in "Passion Patties", after gorging herself on Ms. Bittersweet's cookies. The only way to get rid of the fat was to use an antidote.
* BeautyBrainsAndBrawn: The Beauty.
* BerserkButton: Don't dare to say that Clover uses clothes bought in a liquidation. It never ends well. She doesn't like being turned down by a guy as well.
* BlondeBrunetteRedhead: The Blonde.
* ButtMonkey: She gets this more often than Sam and Alex.
* ClothingDamage: This happens A LOT to Clover. This is especially explored during "Attack Of The 50 Foot Mandy".
* CorruptTheCutie: This happens to Clover's intern, Tara, due to Clover's influence. She's not seen recovering.
* CallToAgriculture: She had to visit a farm during "Spies on the Farm".
* {{Cloudcuckoolander}}: Sometimes she gets lost in her dreams, specially during missions.
* DeadlyUpgrade: She becomes a super agent during "Super Agent Much?". Do you want more?
* DumbBlonde: Sometimes. She's usually smarter than she lets on.
* EveryoneHasStandards: While Clover is obsessed with her appearance, even she felt it was rather ridiculous that Mandy passed out over something as silly as [[IBrokeANail a broken nail]].
* EverythingSoundsSexierInFrench: Occasionally does this.
* TheFashionista: Has always been this, and she pursues fashion design as a major as of Season 6.
* FreudianTrio: The Id to Sam's Superego and Alex's Ego.
* UsefulNotes/FurryFandom: Clover turning into a furry cat? The walking, talking, human animals in the episode Animal World?
* GirlyBruiser: Clover plays the trope the straightest as she's the most girly and feminine of the three.
* GirlyGirl: As mentioned above, Clover's the most feminine of her and her friends. In fact, in the beginning of "Spies on the Farm," Sam and Alex started complaining that Clover's too much of one to really get "down and dirty," to which Clover decided to prove them wrong (and did, which ultimately ended up saving the three of them).
* GoodBadGirl
* GoKartingWithBowser: This happens many times with Clover. For example, during the episodes "[=Sis-KaBOOM-Bah!=]" and "Evil Sorority" when she "fights" alongside with Mandy like...[[LesYay uh...best friends]]? Well, she was under mind-control both times, so it's not like she was willingly hanging out with Mandy.
* GranolaGirl: Stated to be a vegetarian, but her love of fish and seafood would technically make a "pescetarian" (a semi-vegetarian that eats fish and seafood).
* GratuitousFrench: Quite evident.
* HormoneAddledTeenager
* IHaveYouNowMyPretty: Happens to Clover way too many times to count.
* JackOfAllStats: Clovers suits well here. She is strong, but not the strongest. She is smart, but not the smartest. In fact, even Jerry had problems justifying her presence in the team (during the episode "Like, So Totally Not Spies").
* JerkWithAHeartOfGold
* LaserGuidedAmnesia: Too many times to count.
* LovableAlphaBitch: In contrast to Mandy, who was more of a classic AlphaBitch. While Clover can be kind of jerk at times, she is actually quite nice and does understand the importance of friendship and teamwork.
* LovableSexManiac: She is not an extreme example like a certain character from a recent anime by Gainax ([[Anime/PantyAndStockingWithGarterbelt Anarchy Panty]]), but she seems to have a natural tendency for love.
* TheMcCoy
* OnlyOneName: Her full name is never revealed on the show, although WordOfGod states that her full name is "Clover Francise Ewing."
* RapePillageAndBurn: During the episode "Evil Sorority."
* SatelliteLoveInterest: A lot of her {{Temporary Love Interest}}s were this.
* SitcomArchNemesis: Has this relationship with Mandy.
* SkewedPriorities: Sometimes. Clover finds herself caring more about fashion and boys than about the missions she and the girls go on.
* SoreLoser: At times.
* SpaceWhaleAesop: One episode has Clover declaring that it's better to have a big head than to have a big everything else.
* SpoiledSweet: Yes, CaptainObvious!
* StrappedToAnOperatingTable: In "Starstruck."
* TalksLikeASimile: From time to time.
* TemporaryLoveInterest: Any episode where the subplot focuses on the love lives of any of the girls (or all three), Clover has a new boyfriend almost every time--Blaine's the only love interest of hers to last more than one episode in a relationship with Clover.
* TomboyAndGirlyGirl: The Girly Girl to Alex's Tomboy.
* TownGirls: The Femme to Sam's Neither and Alex' Butch.
* {{Tsundere}}: Type A, sometimes.
* ValleyGirl
* ZergRush: Clover was leading the fandom of Ricky Mathis during the episode "A Thing For Musicians" in a very dangerous way.

->'''Voiced by:''' Katie Leigh (Season 1-2), Katie Griffin (Season 3-4)

Alexandra "Alex" has short black hair, tan skin, light brown eyes and her spy catsuit is yellow. Alex is the most naive and innocent of the group, and she's interested in sports and athletics.
* ActionGirl: She usually serves as the heavy hitter, and is also the most athletic of the three.
* {{Adorkable}}: She's a cute sporty girl, sometimes awkward, ditzy and naive, and very friendly.
* [[AfraidOfDoctors Afraid of Dentists]]: But not as much as she is of ''orthodontists''; those are worse.
* TheBabyOfTheBunch: Alex is the youngest and most childlike, seeing as her oldest and dearest friend is a stuffed turtle named Ollie and she has a teddy bear backpack. She is often seen as the little sister of the group, as Sam and Clover are the two big sisters who dominate over her.
* BadassAdorable
* BeautyBrainsAndBrawn: The Brawn.
* BewareTheNiceOnes: She can get pretty mean when she's angry.
* BigEater: Even though she may be the most healthy of the three spies, she likes to eat the most. In "Evil Valentine's Day," we see that she has a dream about candy. In the beginning part of the B-story in "The New Jerry" and the ending of "Animal World," we see her eating nonstop.
* TheBigGuy: Being the most athletic of the trio, though she's also TheChick and TheHeart.
* BlondeBrunetteRedhead: The Brunette.
* ButtMonkey: At times, mostly because of her clumsiness and naivete.
* CharacterTics: In "Evil Valentine's Day", it is shown Alex sucks her thumb while sleeping.
* TheChick: The most optimistic of the trio.
* {{Cloudcuckoolander}}: Sometimes.
* CuteClumsyGirl: Ironically, since she's the athlete of the group.
* TheDitz: Though Clover is more of a blonde ValleyGirl stereotype, Alex is often the ditziest of the three.
* DrivesLikeCrazy: Though she isn't ''too'' bad, she had a lot of trouble passing her driver's exam (it took her at least four tries) and is generally considered the worst driver of the three. But from season three and onwards, she's often the one to drive.
* FreudianTrio: The Ego to Sam's Superego and Clover's Id.
* FriendToAllChildren: "Halloween" reveals Alex is very good at getting along with children.
* FriendToAllLivingThings: She actually wanted to grow up and either be a veterinarian or study animal physiology.
* GamerChick: One of the things Alex loves to do is play video games.
* GirlsLoveStuffedAnimals: She considers a stuff toy turtle to be her oldest friend (she's had it since she was two) and she's been shown with a teddy bear backpack.
* TheHeart: Very much so, she tries to keep her friends together, and is often the mediator between Clover and Sam.
* InSeriesNickname: Her full first name is "Alexandra," but everyone call her "Alex".
* KindlyVet: The major that Alex pursues as of Season 6.
* TheKirk: Even though Sam's the leader, she's more of the captain in this case.
* TheKlutz: Despite being the most athletic, she tends to be clumsy, and has been prone to bad luck (Alex can be very superstitious).
* MixedAncestry: In "Alex Gets Schooled," her dad's shown to be white while her mother appears to be of Hispanic descent, but in Season 6 of "Evil Ice Skater" writers forget this and [[ContinuitySnarl depict her father as looking like her]].
* NiceGirl: By far one of the nicest character in the series.
* OnlyOneName: At least up until season 6, where her father, "Dr. Cassoi", makes a second appearance.
* OnlySaneWoman: [[DependingOnTheWriter Sometimes]], especially when Sam and Clover are bickering.
* PassionateSportsGirl: The most athletic of the three, although her favorite sport appears to be soccer.
* SingleWomanSeeksGoodMan: Alex's three main love interests were definite {{nice guy}}s.
* SpoiledSweet: Alex is probably the most straight-up example of the three.
* SweetTooth: Frequently played for laughs in the 6th season.
* {{Tomboy}}: She loves sports and video games.
* TomboyAndGirlyGirl: The Tomboy to Clover's Girly Girl.
* TomboyWithAGirlyStreak: While she's obviously the most tomboyish of the main three, Alex is also really into fashion and boys, sometimes to the same extremes as Clover.
* TomboyishName: "Alex" is short for Alexandra.
* TownGirls: The Butch to Sam's Neither and Clover's Femme.
* TrademarkFavoriteFood:
** She loves Asian cuisine--especially Chinese food.
** Her favorite type of muffin is natural bran.

->'''Voiced by:''' Lindsay Ridgeway (Season 2-3), Stephanie Broschart (Season 3-5)
Introduced in Seasons 2–3 as the newest recruit to the team.

* AlwaysSomeoneBetter: To Alex in her first appearance.
* [[SixthRanger Fourth Ranger]]
* JackOfAllStats: Probably one of the straightest examples--similar to Clover, Britney's ''good'' at lots of things, but she doesn't necessarily ''excel'' in anything.
* OnlyOneName
* PutOnABus: The only reason she's not a main character. This of course leads to...
* TheBusCameBack: ''Three times'' even!
* TokenMinority: She's presumably of Asian descent.
* TrueBlueFemininity

!Gabriella "Gabby"
->'''Voiced by:''' Jennifer Hale

Sam's mother.

* BlondeBrunetteRedhead: The Brunette in "Mommies Dearest," later the Redhead in "Totally Busted".
* BrainwashedAndCrazy: In "Mommies Dearest".
* FieryRedhead: Gabriella seems to be more spitfire than her daughter .
* HappilyMarried: The B-plot of "The Wedding Crasher" has Sam looking for a gift for her parents' 20th wedding anniversary.
* MyBelovedSmother: She's established as being overprotective of Sam.
* RapunzelHair: Reaches down to her waist like her daughter.
* RedheadInGreen: In her spy outfit but to a lesser extent than Sam as it's more jade than emerald.
* StrongFamilyResemblance: Like with Clover's mom, Stella, and Alex's mom, Carmen, Gabby looks identical to Sam, just older.
* TookALevelInBadass: Trains for and becomes a full time spy in the Season 4 finale.

* BrainwashedAndCrazy: In "Mommies Dearest".
* HospitalHottie: Revealed to be a successful ear surgeon in Season 6.
* MsFanservice: Spends the majority of "Mommies Dearest" in a swimsuit.
* OpenMindedParent: At the end of "Nine Lives," upon learning that Clover wants to become a fashion designer instead of following in her mom's footsteps and becoming a surgeon--while she was a little angry at first, it was mostly because Clover simply didn't tell her.
* StrongFamilyResemblance: Like with Sam's mom, Gabby, and Alex's mom, Carmen, Stella looks identical to Clover, just older.

* BrainwashedAndCrazy: In "Mommies Dearest".
* EducationMama: In "Alex Gets Schooled" her and Alex's father enroll their daughter at Dorsal Academy in England after it was assumed that Alex had gotten straight F’s on her report card (although it later turned out that Alex had gotten A’s and B’s and that Mandy was the one who had gotten straight F’s).
* IWantGrandkids: A mild example. When she's not upset over Alex's grades, she's encouraging Alex to look for a boyfriend.
* ShipperOnDeck: To any guy she thinks her daughter likes.
* StrongFamilyResemblance: Like with Clover's mom, Stella, and Sam's mom, Gabby, Carmen looks identical to Alex, just older.

!Gerald James "Jerry" Lewis
->'''Voiced by:''' Jess Harnell (Season 1-2), Adrian Truss (Season 3-6)

The founder and administrator of W.O.O.H.P., the World Organization Of Human Protection, Jerry is responsible for briefing the girls on their missions. He's generally very serious and professional but he does have a sense of humour, even if it is sometimes a slightly nasty one.
* AccidentalPervert: A milder example, but one episode has him summon the girls early in the morning and recording their interactions with a camcorder. At one point, he does a [[MaleGaze close up]] on [[MsFanservice Sam]], who happens to be in a ''[[ModestyTowel towel in the process]]''. Jerry is [[LuminescentBlush quite embarrassed]] over it.
* AFatherToHisMen: In the final episode of season 5, Alex said he's been like a grandfather to them.
* AuthorityEqualsAsskicking
* BadassGrandpa: He can hold is own defending WOOHP.
* BenevolentBoss: He excuses the girls from class, gives them nifty gadgets, and often sends thank-you gifts in the mail.
* BritishStuffiness: Quite serious and stuffy, and very British.
* CainAndAbel: The Abel to Terrence's Cain.
* {{Catchphrase}}: "Oh, my!" and "Ta-ta for now!", amongst others.
* ColonelBadass
* CoolOldGuy
* CrazyPrepared: He has a gadget for every mission.
* DeadpanSnarker
* HorribleJudgeOfCharacter: Despite being the head of a major spy organization and actually being a master spy (or perhaps due to the pride that comes with the job), Jerry can be oblivious, inattentive and being way too trusting of people he really shouldn't trust--this is especially true in situations where the girls are right and he's wrong.
* IncorruptiblePurePureness: According to a flashback, the only time he ever lied was when he cheated on a test to get through school. Unfortunately for him, his brother ended up taking the blame, causing him to become his evil twin.
* ItAmusedMe: Pretty much the only reason he does half the things to the girls that he does (coming up with increasingly uncomfortable methods of transporting them, monitoring their every move, putting them through insane tests, etc) is because he thinks it's funny.
* JerkWithAHeartOfGold: Does A LOT of stuff to the girls ForTheLulz, particularly his methods of transporting them, but has also saved their lives a number of times.
* TheMentor
* MyGreatestFailure: Selling his brother out when they got caught cheating on an exam.
* NotSoAboveItAll: Despite his years of experience, there're a few times when Jerry falls victim to whatever scheme the VillainOfTheWeek is enacting because he's made the same kind of mistakes the girls sometimes do. He tastes a Passion Patty cookie despite knowing there's something wrong with them, and ends up getting addicted and just as fat as Clover does. He also falls victim to Natalie Valentine's brainwashing cologne and ends up as one of her mindlessly devoted boy toys.
* ParentalSubstitute: He acts as a parental figure to the girls and, at times, scolds them when they messed up. They even share plenty of heartwarming moments. One time he even acts as their father briefly for a talent camp mission.
* PercussivePrevention: In one episode he's zapped with a device that forces him to tell the truth to anyone. After the villain is defeated using a stun ray, the girl's realize they could learn some "dirt" on him before the truth device wears of. Jerry's solution? He zaps ''himself'' with the stun ray.
* ThemeTwinNaming: "Terry" and "Jerry". Oh, and the [[WesternAnimation/TheAmazingSpiez spin-off]] reveals they have a sister named ''Sherry''.
* TinyGuyHugeGirl: He was this with Myrna. [[spoiler:However, it turns out that she wanted to take over WOOHP.]]

[[folder: L.A.M.O.S]]

!Terrence Lewis
->'''Voiced by:''' Matt Charles

* AlwaysIdenticalTwins: As children, they were identical, but Terry had plastic surgery as an adult -- presumably because he wanted an identity outside of being Jerry's twin.
* BigBad: For Season 4, anyway.
* CainAndAbel: The Cain to Jerry's Abel.
* EvilBrit: And an actual Brit.
* EvilTwin: To Jerry.
* MeanBrit
* ThemeTwinNaming: His nickname is "Terry".

!Tim Scam
->'''Voiced by:''' Michael Gough

* CardCarryingVillain: In his first appearance, Clover calls him out on the scumbag he is. His response? A small "Thank you." To be fair, he's far from the only villain in the show who exhibits this behavior.
* CoDragons: With Boogie Gus and Helga Von Guggen in Season 4.
* EvilGenius: He's a crafty little scam artist.
* {{Greed}}: His main motive. Averted in his first appearance, where he wanted to [[OmnicidalManiac drain the Earth of its water supply]], which would have undoubtedly killed all life on the planet (including himself).
* {{Hypocrite}}: Feels that WHOOP never appreciated his genius and the technological advances he brought to the organization, despite the fact that he used said technology for his own selfish interests.
* RecurringCharacter: Has made more appearances than any other villain in the series to date, including Terry.
* TheSociopath: Very likely, considering that his reasons for becoming evil aren't ''as'' petty as most of the other recurring villains. Most of the others suffer from (rather minor) disappointments that cause them to snap. Scam, however, is depicted as perfectly sane (for the most part) and practically kills people for its own sake.
* SdrawkcabAlias: Mac Smit.
** This trope actually becomes a plot-point in one episode, where they finally realize who he really is because they see his name-tag reflected backwards in a metal panel.

!Boogie Gus
->'''Voiced by:''' Joe Motiki

* AlmightyJanitor: Before becoming a villain, he originally worked for WOOHP as part of the custodial staff.
* CoDragons: With Tim Scam and Helga Von Guggen in Season 4.
* DiscoDan: Is he ever.
* FunnyAfro
* MakeWrongWhatOnceWentRight: His first appearance had him travel back in time to become Jerry's friend and convince him to create an evil version of WOOHP called the "World Organization of ''Harming People''."

!Myrna Beesbottom
A former W.H.O.O.P. member. She worked as the girls' "nanny", enforcing strict rules to keep them under control. Her plan involved marrying Jerry so that she could take over W.H.O.O.P.

* FallingInLoveMontage: She had one with Jerry. Too bad it was all lie.
* {{Revenge}}: Why she joined L.A.M.O.S.
* TeamMom: What she seemed like at first.
* TinyGuyHugeGirl: She was involved with Jerry and even married him at one point. However, this was part of her plan to take down W.H.O.O.P.

[[folder:Other characters]]

->'''Voiced by:''' Jennifer Hale

* AlphaBitch: She is a textbook case of this trope (contrast to Clover that is a LovableAlphaBitch). Extra points for being shallow.
* AnnoyingLaugh: Mandy has a ''really'' annoying laugh. It sounds like a goat's bleating.
* BeautyMark
* BigBad: Once as a FutureBadass where she nearly took over the world. And of the one hour ''Totally Busted'' special when she and her lackies get infected by a shampoo that makes them "spy hunters" bent on killing Sam, Clover and Alex.
* BookDumb: She actually got ''straight Fs'' on her report card at one point [[spoiler:(and the report was originally thought to be Alex's, which had As and Bs on it, but it turned out that there was actually a mix-up at their school)]], yet she somehow managed to graduate from high school and go to college.
* DamselInDistress: She gets mistaken for Clover and kidnapped in one episode, resulting in the Spies having to bail her out. Likewise a Halloween episode had the spies have to save her from zombies ''which she herself had accidentally summoned''.
* EvilCounterpart: Not "evil" per se, but when you ''really'' think about it, Mandy's essentially Clover without any of her redeeming qualities, and they do have a lot of the same interests.
* GracefulLadiesLikePurple: She wears a lot of purple on the show—rarely does she wear something that's ''not'' purple. Even all the spysuits she wore on the show are purple.
* {{Jerkass}}: Usually this whenever she's seen.
* JerkWithAHeartOfGold: Surprisingly, Mandy has shown the capacity to be a genuinely nice person, but it never lasts long and she always goes back to being mean again if she's provoked in some way.
* OnlyOneName: It's never revealed what Mandy's last name is.
* PopularIsDumb: It's implied (and proven) that Mandy is BookDumb and does poorly in school.
* PurpleEyes
* RedOniBlueOni: The loud and aggressive Red Oni to her cousin Mindy's calm and collected Blue Oni.
* RichBitch: It's been said (and shown) that Mandy comes from a very wealthy family.
* SitcomArchnemesis: To all the girls, but mainly to Clover. They often compete over boys, popularity contests, bragging rights, the latest fashions, and virtually everything else.
* TheSlacker: Wants to be famous without doing any of the work. She hires an intern to pretty much do everything for her in season 6.
* SixthRanger: Yes, in one episode she wound up discovering the girls' secret and Jerry actually let her join WOOHP on the spot. Naturally, she wound up being a hinderence (though pivotal in stopping that episode's BigBad) that come the end of the mission, she ''begged'' to be released. To which she was mindwiped of the whole events. In her defense, Jerry just threw Mandy into doing the mission with the girls without even doing any kind of basic training.
* SoreLoser: Even more times than Clover herself.
* SpoiledBrat:
* UngratefulBitch: She continues acting like a {{Jerkass}} to Sam, Clover, and Alex even after they saved her in an episode—although to be fair, Mandy usually gets her memory erased afterwards, so she doesn't actually remember Sam, Clover and Alex saving her.
* ValleyGirl: Even worse than Clover—and that's ''really'' saying something!

!Arnold Jackson
->'''Voiced by:''' America—Dee Baker, Joshua Seth; Canada—Rob Tinkler

* {{Adorkable}}
* DrunkWithPower: Happened once when he accidentally found [[AncientArtifact Cats Eye Emerald]] to [[EnergyAbsorption drain people's cool aura]] into himself, nerdifying the victims.
* NiceGuy

->'''Voiced by:''' Darryl Kurylo

* TheAce
* ChickMagnet: All three of the main girls (and their [[SitcomArchNemesis archenemy]]) have a crush on him.
* CurtainsMatchTheWindow: He has brown hair to match his brown eyes.

!Dominique and Caitlin
->'''Voiced by:''' Caitlin—Katie Griffin; Dominique—Andrea Baker

* AmbiguouslyBrown: Caitlin.
* {{Beta Bitch}}es: Dominique and Caitlin follow Mandy's lead.
* GirlPosse: To Mandy.
* {{Satellite Character}}s: Other than being Mandy's friends and occasional rivals to Sam and Alex, respectively, Dominique and Caitlin don't really add much to the story. They're written out of the series after ''Evil Graduation'' and are replaced by Mandy's cousin, Mindy, who's just like Mandy, except she's a DarkSkinnedBlonde with a thick Southern accent.
* ThoseTwoGirls: As previously mentioned, Dominique and Caitlin really don't add much to the show's plot, and when they aren't with Mandy, they're with each other—in fact, Dominique and Caitlin seem closer to each other than they do to Mandy.
* {{Valley Girl}}s: Just like their dominant "friend," Mandy.

->'''Voiced by:''' Katie Griffin

* AlphaBitch
* UsefulNotes/AmericanAccents: Speaks with a very strong southern accent.
* ChuckCunninghamSyndrome: Disappeared with no explanation after season 5.
* DarkSkinnedBlonde: Aside from having dark tanned skin and short blonde hair--and her accent--Mindy's essentially like a Mandy-clone.
* RedOniBlueOni: The much more calm and collected Blue Oni to Mandy's much more loud and aggressive Red Oni.
* SatelliteCharacter: Served as this to Mandy in season 5, replacing Dominique and Caitlin.

->'''Voiced by:''' Scott Beaudin

* AbsenteeActor: "Grabbing the Bully by the Horns", "Evil Ice Skater", "Inferior Designer!", "Little Dude" and "Danger TV" are the only season 6 episodes in which Mandy appears but Trent doesn't.
* BalefulPolymorph: Transforms into a human-scorpion hybrid in "Trent Goes Wild" when his mind wipe goes wrong.
* EeriePaleSkinnedBrunette: A male example.
* ExtremeDoormat: Is constantly bossed around by Mandy.
* TheIntern
* SatelliteCharacter: Replaced Mindy in season 6.
