!!Main Trio
[[folder: General]]

* ActionGirl: They seem to take turns being competent. Sam often leads the team, displays the best hand-to-hand combat skills and gets kidnapped least. Clover combines this with ActionFashionista. Alex usually serves as the heavy hitter, and is also the most athletic of the three.
* AerithAndBob: Sam, Alex, and...[[OddNameOut Clover]].
* BadassAdorable: They are beautiful and deadly at the same time.
* BeautyBrainsAndBrawn: Clover, Sam and Alex.
* BlondeBrunetteRedhead: Clover, Alex and Sam. And the picture even has them in order!
* BoobsOfSteel: All three of them are fairly busty and each has shown off a surprising feat of strength. Out of the three, Alex would qualify the most as she's the most athletic.
* FreudianTrio:
** Superego: Sam intellectual, calculating, level-headed.
** Id: Clover shopaholic, boy-crazy, short-tempered.
** Ego: Alex the most normal and plain of the three.
* GirlyBruiser: All three main agents tend to fall into this, as well as SixthRanger Britney. Clover plays the trope the straightest as she's the most feminine of the lead female characters.
* LovelyAngels: Makes sense, considering [[CharliesAngels who]] they're based on. The PowerTrio version.
* NiceMeanAndInbetween: Alex is the nice one, Clover is the LovableAlphaBitch (in contrast to the series' AlphaBitch Mandy), and Sam is the leader and mediator.
* OnlyOneName: Their last names are usually never mentioned. However WordOfGod states that Clover's full name is "Clover Francise Ewing." See also the AlliterativeName entry for Sam. Alex's last name is implied to be "Vasquez".
* SlapstickKnowsNoGender: Not surprising, since they are both Action Girls and comedy characters.
* SpoiledSweet: With Alex as the most straight-up example of the three, as she's generally the nicest of the three.
* TownGirls:
** Neither: Sam.
** Femme: Clover.
** Butch: Alex.
* {{Womanchild}}: In Season 6, despite being well into University, the girls behave more like their young teenage selves than women supposedly in their 20s.

->'''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. She pursues a Science major in University.
* 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?
* 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.
* BewareTheNiceOnes: You do not want to get her angry.
* BraidsOfAction: Temporarily, during the Gladiator episode.
* BrainwashedAndCrazy: A RunningGag in the show is that she winds up like this on a routine basis.
* DeadpanSnarker: The most sarcastic of the group. She sometimes gets annoyed by Alex and Clover's comments and actions and will reply with a sarcastic remark or joke. One example was in "Futureshock!". The cheerleaders were doing a routine and Mandy fell off the human pyramid and everyone gasped. While Alex noted that the fall obviously was not a part of the routine, Sam suggested that it be worked in.
* ExtremeOmnivore: Eats a hot towel while at a sushi restaurant, and seems to enjoy it. However, in her defense, 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 using gray-colored paint]].
* 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.
* OnlySaneWoman: [[DependingOnTheWriter Most of the time.]]
* RapunzelHair: Her hair reaches to her waist.
* RedheadInGreen: In her spy outfit.
* SignificantGreenEyedRedhead: A red haired girl with green eyes.
* TheSmartGirl: She's usually the one who takes control over the girls' missions and puts her smarts to use.
%%* TheSpock
* TeamMom: She's generally the most mature and responsible of the main three.
* 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).
* 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". She pursues a Clothing Design major in University.
* 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.
* 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.
* 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.
* ButtMonkey: She gets this more often than the other girls. There are some occasions where Sam or Alex gets this end of the stick, though.
* CatGirl: She became a catgirl in the episode "Wild Style" after being injected with a serum.
* 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.
* 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: She's ultimately a good person, but she also likes flirting and dating...a lot.
* 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: The most boy-crazy of the trio.
* 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: She can be shallow, snobby, and conceited, but is a loyal friend to Alex and Sam.
* LaserGuidedAmnesia: Too many times to count.
* LovableAlphaBitch: In contrast to Mandy, who was more of a classic AlphaBitch. While Clover can be kind of a jerk at times, she is actually quite nice and does understand the importance of friendship and teamwork.
%%* TheMcCoy
* NotSoDifferent: Despite their hatred for each other, Clover and Mandy have similarities. They are both vain about their appearance and can be boy crazy. They also don't care too much about their academics. The difference is that despite Clover's bad traits, she's still a good person to others. Mandy, on the other hand, is a jerkass and a narcissist.
* OddNameOut: In more ways than one --
** Clover's the only that doesn't go by a nickname, since Sam's real name is "Samantha" and Alex's real name is "Alexandra."
** Clover's the only one to not have a TomboyishName (seems rather fitting, since she's the most feminine of the three).
** "Sam," "Samantha," "Alex" and "Alexandra" are all fairly common names while "Clover" (though it is an actual name) isn't nearly as common.
* 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.
* SlapstickKnowsNoGender: Due to being the biggest ButtMonkey of the trio. A good idea for a drinking game: if you happen to be watching a ''Totally Spies'' marathon or are watching the show on DVD, take a drink every time something bad happens to Clover. You won't be sober for long.
* SmittenTeenageGirl: She seems to have a natural tendency for love.
* SoreLoser: At times. She can't stand losing to Mandy.
* SpaceWhaleAesop: One episode has Clover declaring that it's better to have a big head than to have a big everything else.
* 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.
%%* {{Tsundere}}:
* ValleyGirl: Clover's fluent in surf lingo and Valley Girl-style slang terms.
* ZergRush: Clover was leading the fandom of Ricky Mathis during the episode "A Thing For Musicians" in a very dangerous way.

->'''Voiced by:''' Creator/KatieLeigh (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. She pursues a Veterinarian major in University.
* {{Adorkable}}: She's a cute sporty girl, sometimes awkward, ditzy and naive, and very friendly.
* AfraidOfDoctors: But not as much as she is of ''orthodontists''; those are worse.
* TheBabyOfTheBunch: Alex is the youngest and most childlike and is often seen as the little sister of the group, as Sam and Clover are the two big sisters who dominate over her.
* 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.
* TheBigGal: Being the most athletic of the trio, though she's also TheChick and TheHeart.
* 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.
* CatGirl: Got her turn in Season 6 when she got scratched by mutated cat claw. Unlike Clover, she actually ''liked'' the change and asked Jerry if she could keep it.
* TheChick: The most optimistic of the trio.
%%* {{Cloudcuckoolander}}: Sometimes.
* CuteClumsyGirl: Ironic, 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: Typically portrayed as being the worst driver of the three spies--according to them, Alex barely passed Driver's Education and she had to take the road test to get her driver's license at least four times. But from season three and onwards, she's often the one to drive, and it's shown that her driving skills have improved.
* 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 rather 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.
* 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.
* 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.
* TrademarkFavoriteFood:
** She loves Asian cuisine--especially Chinese food.
** Her favorite type of muffin is natural bran.

!!Other members
[[folder: Gerald James "Jerry" Lewis]]
->'''Voiced by:''' Creator/JessHarnell (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: In one episode, even the heroines are very surprised at how well Jerry can handle himself in a fight.
* BadassGrandpa: He can hold is own defending WOOHP. Despite his thin and non-athletic appearance, he has in fact demonstrated highly impressive combat and piloting skills superior to those displayed by the girls themselves, including running up (and down) the side of a building
* BenevolentBoss: He excuses the girls from class, gives them nifty gadgets, and often sends thank-you gifts in the mail.
* BigGood: The leader of WOOHP.
* 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.
* CoolOldGuy: On the rare occasion that he's personally called into action, he consistently outclasses the Spies themselves.
* CrazyPrepared: He has a gadget for every mission.
%%* DeadpanSnarker
* HorribleJudgeOfCharacter: Despite being a master spy and the head of a major spy organization (or perhaps due to the pride that comes with the job), Jerry can be oblivious, inattentive, and overly trusting of people whom one really shouldn't trust. This is especially true in situations where the girls are right and he is 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 when they were kids.
* 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 (since there's no antidote for it). Jerry's solution? He zaps ''himself'' with the stun ray, effectively knocking him out and the truth serum wears off.
* ThemeTwinNaming: "Terry" and "Jerry". Oh, and the [[WesternAnimation/TheAmazingSpiez spin-off]] reveals they have a sister named ''Sherry''.
* TinyGuyHugeGirl: He was this with Myrna--they're roughly the same height, but when it comes to build, she's considerably larger than he is.[[spoiler: However, it turns out that she wanted to take over WOOHP.]]

[[folder: Britney]]
->'''Voiced by:''' Lindsay Ridgeway (Season 2-3), Stephanie Broschart (Season 3-5)

Introduced in Seasons 23 as the newest recruit to the team.

* AlwaysSomeoneBetter: She is very intelligent and is also very skilled, but this trait of hers made Alex become jealous of her at some point during many occasions (believing that Britney was sent to replace her).
* TheBusCameBack: ''Three times'' even!
* 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.
* NiceGirl: She has a cheerful personality.
* OnlyOneName: Just known as "Britney".
* PutOnABus: The only reason she's not a main character.
* SixthRanger: Usually joins in the group during her episodes.
* TheReveal: In the fifth season, Britney admits that she looks up to Alex as a role model (calling "WOOHP's ultimately superspy") and she and Alex [[CommonalityConnection end up becoming friends after discovering [they actually have a lot in common.]]
* TokenMinority: She's presumably of Asian descent.
* TrueBlueFemininity: All her mission outfit are blue. She has also bright dark blue hair.

[[folder: G.L.A.D.I.S]]
->'''Voiced by:''' Stevie Vallance

G.L.A.D.I.S. (Gadget Lending And Distribution Interactive System) was introduced in the episode "Physics 101 Much?" of Season 3, as a Gadget lending device.

* AIIsACrapshoot: G.L.A.D.I.S. is usually just annoying, but not evil. However, in one episode, (at an office Christmas party that Jerry pretty much dragged the three protagonists too) she becomes homicidal after Clover spills punch on her cabinet. Jerry later admits, embarrassed, that he programmed her by downloading the intelligence from the brain of an insane EvilGenius who is in prison for trying to start World War III, and when they question the inmate, they find out that he's allergic to cranberries (which make him "even crazier than usual"); Clover realizes that the punch was cranberry-flavored. The Spies are forced to accept the madman's help before G.L.A.D.I.S. carries out his original plan, which involves tricking the world's superpowers into launching its nuclear arsenals at each other.
* ArtificialIntelligence: She appears to have a mind of her own, even sometimes claiming she's the true leader of WOOHP. In several episodes she ignores Jerry's orders and distributes the gadgets she believes are needed for the mission.
* ComputerVoice: She speaks with a female voice.
%%* DeadpanSnarker
* PutOnABus: In the episode "Evil Roommate" Jerry had G.L.A.D.I.S. dismantled due to her attitude--the real life reason was that the fans didn't like her.


[[folder: 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".

[[folder: 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.

[[folder: 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: An African-American 1970s/1980s loving villain/former WOOHP janitor.
* FunnyAfro: Has a afro hairstyle.
* 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''."

[[folder: 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:Helga Von Guggen]]
->'''Voiced by:''' Adrienne Barbeau
* GenuineHumanHide: Guggen transforms people into PettingZooPeople before skinning them alive and making clothes out of them. Her introductory episode has her showing off her latest fashion which she boasts was made out of genuine "lawyer."
%%* KnightOfCerebus
* {{Revenge}}: Her plan in her second appearance revolves around this.
* SerialKiller: In her first appearance, she had skinned a ship containing two hundred people alive, using their furs to make clothing out of them.

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

* 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.
* TheBadGuyWins: Mostly in season 1 and on the high school side of things. She usually manages to steal Clover's love interest due some circumstances like giving up a date.
%%* 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 once 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.
* ButtMonkey: Mandy becomes this at the end of any episode, due to her JerkAss status.
* CuteButCacophonic: Despite her good looks, she has a ''very'' grating voice.
* 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 what Clover would be without any of her redeeming qualities--and Clover and Mandy do share 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.
* {{Narcissist}}: Mandy comes off as this with her constant bragging about how popular and beautiful she is. She's arrogant, vain, loves all types of attention, and she also has a terrible attitude to boot.
* 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: She has purple eyes that match her skin tone personality, and clothing.
* 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 hindrance (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: Her mother alternates between spoiling Mandy and disciplining her for lackluster grades.
* UngratefulBitch:
** She continues acting like a {{Jerkass}} to Sam, Clover, and Alex even after they saved her in an episode. Then again Mandy usually gets her memory erased afterwards, so she doesn't actually remember Sam, Clover and Alex saving her.
** This is averted in an episode when Sam saves her hair from getting messed up in an art class. Mandy is so grateful, she tries hard to make friends with Sam, much to Sam's chagrin. This is reversed in the end when she, once again, gets her memory wiped after she finds out that Sam, Clover, and Alex are spies and she wants to tell everybody she knows.
* ValleyGirl: Even worse than Clover--and that's ''really'' saying something!
