[[folder:The Boys]]
!! Common to the four:
* DeadpanSnarker: They all have plenty of snarky moments, but Carlos' are less frequent.
* FourManBand:
** OnlySaneMan: Kendall
** TheSmartGuy: Logan
** ButtMonkey: Carlos
** The Pervert: James
* FourTemperamentEnsemble:
** Kendall: Phlegmatic
** Logan: Melancholic
** Carlos: Sanguine
** James: Choleric
* LovableJock: They were on the hockey team back in Minnesota.
* MinnesotaNice: The four of them, despite their quirks and fails, are genuinely {{Nice Guy}}s, which sometimes clashes with the LA lifestyle.
* MrFanservice: James being the most notable.
* PrettyBoy: Many girls in-universe have said aloud they are cute.

!!Kendall Knight
--> Played by Kendall Schmidt
De-facto leader of the boys. He is the only one who doesn't want to let being a celebrity get to his head. He is dating Jo.
* AllGirlsWantBadBoys: Standard tradition is that ''every'' band has to have ''a'' bad boy. Kendall more or less got the job by default, mainly due to his relative sanity.
* BerserkButton: Insulting or belittling his friends. He's normally the calm and collected one, but in the pilot, when Gustavo told James he had no talent, Kendall went absolutely nuts and had to be dragged out by security.
* BewareTheNiceOnes: Kendall can be your best friend or your worst nightmare. When Jo's co-star fakes the two of them being in a relationship for the press and mocks Kendall about it, Kendall flat out tries punching him.
* CoolBigBro: To Katie. Unlike many brother-sister bickering in sitcoms, Kendall and Katie have the best on-screen sibling relationship and aid each other with their schemes. Katie often calls Kendall "Big Brother" with affection.
* {{Determinator}}: In ''Big Time Movie'', he gets punched in the ribs by one of Atticus Moon's henchmen, and gets up as if it were nothing. Keep in mind, that particular henchmen a ''mallet made of silver'' for a hand.
* DisappearedDad: Since Kendall and Katie set dates for their mom, it's assumed their father is either divorced or gone. Nobody talks about him.
* TheLeader: He is pretty much the leader of Big Time Rush.
* RealMenWearPink: In "Big Time Secret", he has been sneaking with Camille without telling the other guys because he wanted to try a ''Figure Skating'' competition. He tried to hide it because they, as hockey players, would mock it without mercy.
* RousingSpeech: He is the one who cheers the group with his speeches about friendship, even when they are getting into crazy schemes. "Big Time Cameo" even lampshades this when the writers of the sitcom made [[{{Flanderization}} Kendall's character in the script]] as "The Motivational-Speeches guy".
* StraightMan: Compared to his friends, Kendall usually is the one who keeps the cool and actively tries to solve the situations. It can either go well or fail miserably.

!![[spoiler:Hortense]] Logan Mitchell
--> Played by Logan Henderson
The smart one who has plans to become a doctor. Currently dating Camille.
* {{Adorkable}}: Occasional lab coat, check. Brain of the group, check. Almost always wears suit/necktie/t-shirt, check. Cute? DOUBLE CHECK.
* AttractiveBentGender[=/=]WholesomeCrossdresser: He got into a lecture held in an Only-Women college, and only got discovered because he blew his cover in front of a room full of {{Straw Feminist}}s.
* BrainyBrunette: He is the smartest of the group, to the point all of his classmates were fighting to be partners with him in ''Green Time Rush''.
* ButtMonkey: When the guys are worried that Wayne Wayne will have someone kicked out of the band, James remarks that he thinks it'll be Logan... ''while crouching right next to him''. Later, Gustavo and Griffin remark that they thought Logan would be the one kicked out of the band, ''Griffin going so far as to use the intercom so that Logan would hear him''.
** Logan was also sat on by Gustavo and ran over by a horde of fangirls. Boy can't catch a break.
** In "Big Time Break", Logan goes through a lot of trouble just to get a lecture from his favorite math celebrity teacher just to find out she's a [[StrawFeminist crazy feminist]] and, latter, getting beaten up by a bunch of girls.
** In "Welcome Back Big Time", Logan does several weeks of school work in a day - not just his own, but ''the rest of the group's too''. All James and Kendall do is something very minute so they could claim the work was their own, but Carlos ''just signs his name''.
*** Somehow their teacher doesn't put 2 and 2 together when Carlos' project includes ''a working laser''.
** In "Big Time Moms," it is revealed that [[spoiler: Logan's real name is Hortense,]] but James' mother makes him change it.
** In ''Big Time Movie'' Logan gets shot by tranquilizing dart guns... [[RuleOfThree three times]].
** In "Big Time Pranks", the guys hold a prank contest among all of the Palm Woods tenants and Logan is the first one to be disqualified. Funny thing is, nobody even pranks him, he actually pranks himself.
* CrazyJealousGuy: He can be this for Camille. In "Big Time Secrets", he started stalking Kendall and Camille because he thought they were secretly dating. He literally became AxCrazy and started chasing them with an ax-shaped guitar.
* TheDitherer: {{Lampshaded}} in "Big Time Songwriters."
-->'''Carlos:''' Okay, then you pick the song. Which one is better, Logan? The "O Song," or the "Yeah Song"?
-->'''Logan:''' You guys, I'd really rather not get into the middle of this, so um...
-->'''Carlos:''' Big surprise. ''Logan'' doesn't want to make a decision!
* EmbarrassingFirstName: Logan's first name is ''Hortense''. Thank goodness for James' mom.
-->'''Kendall:''' Me, Carlos and ''Hortense'' are here to see James.
-->'''Mrs. Diamond:''' I don't like the name Hortense. Call him Logan from now on.
* NotSoAboveItAll: Even thought he is the smartest of the group and wants to shape himself into the responsible one, he is not free of being impulsive or clumsy as well.

!!Carlos Garcia
--> Played by Carlos Pena Jr.
One of the most eccentric members of the group. Constantly wears a helmet.
* AgentMulder: He believes in almost anything. He even bought bottles of Zom-be-gone to protect himself from a zombie apocalypse.
* AttractiveBentGender: In "Big Time Halloween", Gustavo's machine briefly turns him into a beauty queen.
* BigEater: He is always seen with a corndog or getting very excited when food is mentioned.
* CloudCuckooLander: He goes around with his helmet and throws himself into Shenanigans on daily basis. When he is trying to be the voice of reason, you know that the situation is out of control.
** One example is that his life dream is to be a ''superhero''.
** For his Earth Day project, his idea (and James') was to ''have a cow in every house''. Miss Collins immediately rejected their project.
* CompanionCube: His helmet.
* HollywoodDateless: Even thought he is attractive, nice and is part of a very popular boyband, most of the episodes he is either looking for a girlfriend or trying to impress The Jennifers.
* {{Keet}}: He is the most hyper of the group. Gustavo has to change the break-up song into a happy one because Carlos was too cheerful to sing it.
* PintsizedPowerhouse: He's the shortest of the guys which is ironic because he's the oldest of the four at ''22'', but he's also the toughest.
* TrademarkFavoriteFood: Corndogs.

!!James Diamond
--> Played by James Maslow
The best looking guy in the group, and he takes pride in it. Comes off as arrogant. Not dating anyone, but it's kind of his life style. By the series finale [[spoiler: he and Lucy seem to have become a couple]].
* AfraidOfNeedles: The only way he got over this was because his allergy bloated him in horrifying levels.
* CatchPhrase: [[NoIndoorVoice "She will be]] [[LargeHam MINE!"]] whenever there's a pretty girl he's interested in (mostly directed at Lucy).
* TheDitz[=/=]BrainlessBeauty: Downplayed. He falls pretty easy on scams (for example the fan who ended up kidnapping and locking him in a basement) and isn't very academically smart, as he only cares about his looks.
* DramaQueen: He tends to react like this a lot, like when Lucy friendzoned him the first time around, or when he started to apply magazine tests to Kendall, answering as if they were in a relationship.
* DudeLooksLikeALady: Lampshaded in "Big Time Christmas." In the animated music video with Snoop Dog, the band is depicted as squirrels, but James is the only one with eyelashes.
* HiddenDepths: In "Big Time Fans", James works out in front of pictures of his heroes: Creator/DavidHasselhoff, UsefulNotes/MahatmaGandhi, and UsefulNotes/AbrahamLincoln.
* IJustWantToBeSpecial: He is the most interested in becoming famous in the pilot.
* MySisterIsOffLimits: Since he views Katie as his own sister as well, he gets very overprotective when she goes on a date with another guy.
* {{Narcissist}}: He tends to think only of himself.
* PapaWolf: Towards Katie. He acts even more like a [[MySisterIsOffLimits jealous big brother]] than Kendall himself.

!!Katie Knight
--> Played by Ciara Bravo
Kendall's younger sister. She is dangerously clever and definitely [[WiseBeyondTheirYears wise beyond her years]]. Always thinking of money making schemes. Regardless, there are times when she acts like a normal ten-year-old girl, but is 100% confident in her plans.

* AnnoyingYoungerSibling: Averted. She and Kendall actually have a good relationship with one another, as she does with the rest of the members of BTR.

* BewareTheCuteOnes: Do not mess with this girl. When she gets in the mood or has been crossed, she could make [[Series/DrakeAndJosh Meagan Parker]] look like an angel by comparison.
* BigBrotherWorship: Unlike many brother-sister bickering dynamics in sitcoms, Kendall and Katie have the best on-screen sibling relationship and aid each other with their schemes. Katie often calls Kendall "Big Brother" with affection.
* DisappearedDad: Since Kendall and Katie set dates for their mom, it's assumed their father is either divorced or gone. Nobody talks about him.
* {{Foil}}: To both Kendall and her mom. She is the only one in the family who adapts quickly to the competitive and business-focused Hollywood, while they keep their [[MinnesotaNice Minnesota lifestyle views]]. Still, they are very close as a family and can work their way out of any situation.
* {{Guile Hero}}ine: She is equally as ambitious and manipulative as Bitters, or even Griffin, but her heart is in good place.
* ImprobableAge: One episode has her put in charge of the label, which she is exceptional at.
* {{Leitmotif}}: A mockingly sweet melody. Also used with some other characters, however.
* NotSoAboveItAll: Even thought she is unbelievably independent and smart, she is still a 13-year-old kid and has moments of immaturity. This is shown whenever she has to learn that her mother still knows better than her in other aspects.
* PuppyDogEyes: She's highly aware of this and knows how to use them.
* SpoiledBrat: She tries to get spoiled by her mother as much as possible. In "Big Time Strike", she trains BTR to be just as spoiled as she is by demanding Gustavo an ice cream bar, a hair salon, a petting zoo, hot tubs and more.

!!Jo Taylor
--> Played by Katelyn Tarver
A fairly successful young actress and Kendall's girlfriend. In season two she had to leave to film a movie for three years, [[spoiler: but she returns in season 3]].
* CareerVersusMan: When Jo is introduced, she tries to avoid relationships to focus on her acting career, but she ends up dating Kendall anyway. During their relationship, many episodes showcased how they succeeded in keeping their relationship despite having very tight schedules. Jo eventually gets offered a 3-year gig in New Zealand and is torn between taking it or staying with Kendall, with him later encouraging her to follow her dreams. [[spoiler:She returns earlier anyway and they rekindle their relationship]].
* CuteBruiser: Trained in Judo, flips Kendall over her shoulder several times without appearing strained.
-->'''Jo:''' [[BadassBoast Just let me know when you had enough.]]
* FirstGirlWins: An entire episode is dedicated to Kendall choosing between her and [[spoiler: Lucy]]. He chooses [[spoiler: Jo]].
* GirlNextDoor: Introduced as/fantasized as such, but subverted by her career-oriented ambition and subsequent success making her less "accessible."
* GirlfriendInCanada: She claims she has a boyfriend named "Travis" back in North Carolina so Kendall won't flirt with her. Once Kendall realizes and starts to test her, she hires a guy to pretend to be "Travis", but it fails immediately.
* {{Hypocrite}}: Calls Kendall out for being jealous of her completely professional relationship with Jet yet 4 episodes prior she was jealous of Kendall helping Jordin Sparks [[labelnote:Note]] However, both instances weren't without justification. Jet did text Jo "I feel the same way about you" implying romantic feelings between the two and Jo did catch Kendall in multiple instances between him and Jordin that could easily been mistaken for romance [[/labelnote]]
* OfficialCouple: With Kendall.
* OnlySaneWoman: Between Camille's LargeHam moments and the boys being the crazy bunch, Jo is often relegated to be this.
* PutOnABus: Breaks up with Kendall to pursue an acting gig in New Zealand.
** TheBusCameBack: Just in time to find Kendall and [[spoiler: Lucy]] making out in the elevator.
* RomanticInterest: She is introduced to have the boys fight over who impresses her first. Then she becomes Kendall's girlfriend two episodes later.

* BetaCouple: With Logan.
* ForcefulKiss: She kisses Logan many times this way.
* TheGlomp: She has the habit of welcoming Logan with a Tackle-Hug. In "Big Time Returns", Logan's subplot has him trying to get Camille to tackle him and her trying to resist the temptation of doing it.
* JustFriends: She and James only kissed because they got too into character while practicing for a role, not because there was any attraction. They promptly feel horrified and guilty by this and try to find a way to tell Logan.
* LargeHam: InUniverse. She tends to exagerate on her dramatic scenes.
* MethodActing: In-Universe, which is also her main forte, but it's also why she keeps flunking her auditions. (On one occasion she brought ''explosives'' for her witch character.)
* SavvyGuyEnergeticGirl: The Energetic Girl to Loganís Savvy Guy.
* SlapSlapKiss: Literally how her relationship with Logan works. She often slaps him (for auditions, but still) and in the drop of the hat they flip to MakeOutKids.
* StraightMan: In later seasons, she becomes less hammy and more sensible and mature than Logan.
* SureLetsGoWithThat: She purposely sabotaged Logan's turn to flirt with Jo by smooching him [[BlatantLies for an audition]].
-->'''Kendall:''' Series/OneTreeHill?
-->'''Camille:''' SureLetsGoWithThat.
* ThoseTwoGirls: She and Jo become best friends and are often hanging out when their are not working or with their boyfriends.

!!The Jennifers
--> Played by Denyse Tontz as Jennifer 1, Spencer Locke/Kelli Goss as Jennifer 2, Savannah Jayde as Jennifer 3
Three beautiful but high-maintenance girls of the same name. Notorious around the Palm Woods for their slow-motion entrances and rejecting any guy without a movie deal or a top ten single.

* AlphaBitch: The three of them have ruled Palm Woods by being mean to the newbies to "mark territory".
* BlondeBrunetteRedhead: Played with. Jennifer 1 is Brunette, Jennifer 2 is Blonde, Jennifer 3 is African-American with black or auburn-ish hair, depending on how she has it done.
* TheFashionista: The three of them. Averted when Jennifer 1 is separated from the others, Carlos is told that the three of them help each other, reason why she was acting strange during their prom date.
* GirlPosse: So much that they can't keep balance if the group is incomplete. When Jennifer 2 was absent, they completed the trio by ''replacing her with Carlos''.
* GiveGeeksAChance: Even thought Carlos is no geek (but very hyper instead), they consider him the "better option" compared to the other guys, given their ridiculous high standards.
* HiddenDepths: Even thought they are snobby and divas, they do have soft spots for Carlos, with blonde and brunette/Latina Jennifer dating him at some point or another.
* LovableAlphaBitch: They can be completely mean and controlling, but they do have soft spots.
* {{Mama Bear}}s: They warned Carlos about breaking Brunette Jennifer's heart and the subsiding consequences.
* OneSteveLimit: Triple averted with them, and that's also why they are called [[ExactlyWhatItSaysOnTheTin "The Jennifers"]]. Also with Kendall's mom.
* PutOnABus:
** In "Big Time Fever", Jennifer 2 (Spencer Locke) was away. This becomes a plot point of the episode, making Carlos fill the void. It's never stated in later episodes if Jennifer 2 (Kelli Goss) is that same character or another blonde girl also named Jennifer.
** They are notably absent during most of Season 4 until the final chapter, except for Jennifer 1, who is replaced by a cardboard cutout carried by the other two. According to them, she had to stay longer on the movie they were filming overseas during the season.
* RomanticFalseLead: Carlos has been trying to be the boyfriend of either of them for three seasons. Each one gets to date him at different points, but ultimately he chooses Alexa Vega, who he met that day.
* TokenTrio: Jennifer 1 is [[AmbiguouslyBrown implied to be latina]], Jennifer 2 is blonde and Jennifer 3 is african-american.

!!Jett Stetson
--> Played by David Cade
Jo's co-star, who is one of the most popular actors on the InUniverse show ''New Town High''. He has a crush on Jo and a bitter rivalry with Kendall.

* ActorShipping: Invoked. Jet tries to pull this with Jo so he can get even more publicity for New Town High.
* AttentionWhore: Adores publicity, no matter what's the subject.
* ArcVillain: For Kendall and Jo's relationship, but the rivalry was in its prime for long enough to make him...
* BigBad: For season two.
* BrainlessBeauty: You thought James was vain? Jett is [[UpToEleven Ten times worse]]. Instead of helping Kendall on their school project, he wasted resources, time and ''made himself a big cardboard box to pose as a Ken doll''.
* TheDitz: He has absolutely no interest for anything outside of his appearance. In the Finale, he completely forgot the Tween Choice Awards date, missing also his nomination for "Perfect Hair".
* EvilCounterpart: To Kendall and James. While Kendall is smart, a loyal friend and loving boyfriend, Jett is completely egocentric, dumb, selfish (almost like James but without his good attributes) and only wants to hook-up with Jo for publicity.
* JerkJock: Acts like one.
* JerkWithAHeartOfJerk: In ''Big Time Sneakers'' he actually worked with Jo's publicist to try to strong arm Kendall and Jo into breaking up, or else they will ruin Jo's job on ''New Town High''.
* RomanticFalseLead: To Jo.
* SixthRanger: In EnemyMine sistuations

!!Lucille "Lucy" Stone
--> Played by Creator/MaleseJow
A girl who moves into the Palm Woods after [[spoiler: Jo leaves.]] There was some romantic tension between her and Kendall, but it faded when [[spoiler: Jo comes back.]] As of [[spoiler: season 4, she's back, and is developing romantic tension with James and seems to be finally dating him in the finale.]]
* AsianAndNerdy: Her parents think that she is this as a classically trained concert violinist. In reality, she averts this trope.
* BeCarefulWithThatAx: She has a guitar with an ax blade on it. Logan steals it when he thinks Kendall and Camille are dating.
* FreakyFashionMildMind: Lucy has dyed red streaked hair and dresses like a stereotypical rocker chick, but is really quite friendly.
* HugeGuyTinyGirl: With James in season 4. At 5'3 Malese is the shortest of the adult female cast and at 6'1 James is the tallest of the male.
* IWantMyBelovedToBeHappy: [[spoiler:She left Palm Woods to allow Jo and Kendall to rekindle their relationship and didn't make drama for it.]]

* OnlySaneMan: In "Big Time Lies" she says that guys are all weird.
* TheRockstar: In a subversion, she's fairly level-headed.

!!Jennifer Knight

Kendall's mother, who moves too the Palm Woods with the boys. She is probably the most sensible character on the show and acts as TeamMom.
* AlmightyMom: Even Katie knows there're things her mom does better than her.
* BlondeBrunetteRedhead: The redhead to Brooke Diamond's blonde and Sylvia and Joanna's brunettes.
* {{Foil}}: To Katie. While she is a lovable mom who sometimes goes into MyBelovedSmother, Katie is very independent and ambicious, which clashes with [[MinnesotaNice her way to do things in life]].
* GoodParents: For a single mother watching 5 kids, 3 of whom aren't hers, she does a pretty amazing job. She's protective, supportive, and caring to all of them, and treats James, Carlos, and Logan [[ParentalSubstitute as her own]].
* LastNameBasis: Aside from Kendall and Katie (they call her "Mom"), everyone else always refers to her as "Mrs. Knight" or "Mama Knight". Whether this is avoid confusion with [[TokenTrio The Jennifers]] is anyone's guess. Her first name was used once by James' mom.
* MamaBear: She beat up another mom because she insulted Katie.
* MinnesotaNice: Tries to adapt to LA while still being nice, but doesn't always work.
* ParentalSubstitute: To James, Logan, and Carlos.

* TheChewToy: As recurring ButtMonkey, he is also pronte to receive all the physical suffering (Jenny once stabbed his hand with a pen).
* EvilLaugh: A RunningGag is that everything happens to him in the midle of his EvilGloating Laugh.
* FatBastard: During his Jerkass moments.
* IntergenerationalFriendship: With Katie, since she seems to hang out more with grown-ups than with kids her age.
* JerkWithAHeartOfGold: While he is greedy and unsympathetic to his clients, he also has his moments towards the boys or Katie.
* MommasBoy: He adores his mom, reason why he tries to pretend he has a family, just so she won't get dissapointed on him.

!!Budda Bob
--> Played by Creator/DaranNorris

Janitor at the Palm Woods. While appearing to be crazy, he is actually very sensible and likable.

* AlmightyJanitor: Played with. He is very capable and has many hidden depths, but his communication skills are average and he is not very smart.

* CompanionCube: With Plungie.
* EasyAmnesia: When Ms. Knight accidentally hits him with a pan, he starts believing he is [[ActorAllusion the Fairy Godparent]] [[WesternAnimation/TheFairlyOddParents Cosmo]].
* FaceOfAThug: When moving into Palm Woods, Mrs. Knight thought he was an AxCrazy serial killer after seing him in [[NotWhatItLooksLike very unlikely situations]]. It took her a while to realize he was the maintenance guy.
--> '''Katie''': My mom thinks you're an ax maniac.
--> '''Budda Bob''': That explains why she screams everytime she sees me.
* HiddenDepths: In ''Big Time Wedding'' Buddha Bob reveals that he's a great cook, mechanic, teller of make-believe stories and can re-tile a bathroom.

The boys manager. A disgraced music manager from the 90's who is trying to get back on top. He refers to the boys as "dogs" and nearly every episode has him writing a song.

* BadBoss: He is constantly screaming at people. How bad of a boss? With only the mention of his name, Nicole Scherzinger threw a telephone at him for "creative differences".
** He takes it up a level as this in "Big Time Strike" by shocking the boys if they slack off.
* TheChewToy: He gets beaten up, suffers from frequent rage induced high blood-pressure (courtesy of Kendall) and he once even got hit by Snoop Dog's limousine, getting away with few bruises and a lot of bandages
* HatesEveryoneEqually: Lampshaded by Katie.
--> '''Katie''': Don't you need to be in love to write a love song? You're not wearing a ring and... Don't you hate every living thing?
* '''HotBlooded''': His rage induced moments (mostly caused by Kendall) can cause an earthquake of 5.5
* JerkWithAHeartOfGold: He clearly grows to care about the guys and even Katie, eventually admitting that he loved them.
* LargeHam: And '''How!''' All of his lines are delivered with screams.
* MadeOfIron: He got hit by a Snoop Dog's limousine in the Christmas episode and by a bus ''twice'' in "Big Time Scandal" and came out both with minor injuries and a lot of bandages.
* NoIndoorVoice: He shouts whenever he is angry or annoyed... which makes it an everyday occurrence.
* PetTheDog[=/=]KickTheDog: He literally calls the boys "Dogs" (or "Monkey-dogs"), and alternates between these two.
** He literally calls "ThrowTheDogABone" when he lets the boys keep their remodeled crib.
** The emergency password to his secret vault is "My Dogs" with the hint being "Something You Love".
* RecordProducer: Of the Producer from Hell kind, but played for laughs. All his former artists grew to hate him due to his bad temper. Kelly points out that Big Time Rush is the first group Gustavo grew to like. Later he grows into Acrimony Producer after he and the boys get along better and Griffin becomes more antagonistic.
* UngratefulBastard: BTR and Kelly both call him out for almost never thanking BTR for all their hard work. After all, BTR is the reason Gustavo can afford a huge mansion packed with expensive luxuries.
* WouldHitAGirl: With comedic purposes about his interactions with Kelly.
** Well, in that episode, Kelly was [[ComicRolePlay "Gustavo"]].

!!Kelly Wainwright
--> Played by Tanya Chisholm

Gustavo's [[WomenAreWiser saner]] assistant.

* BeleagueredAssistant: In Gustavo's worst moments.
* BewareTheNiceOnes: She's nice but can be very fierce if pushed. Then again it's the entertainment business, so she'd have to be.
* MamaBear: Towards the boys. She once snapped when Gustavo decided to break Carlos' heart by hiring an actress just so he could sing a break-up song properly. Her response? She threatened to smash every one of his trophies with a baseball bat if Carlos got hurt in any way.
* MoralityPet: To Gustavo occasionally.
* ParentalSubstitute: She acts very maternal towards the boys and will protect them if they're threatened.
* PromotionToOpeningTitles: Season two and beyond.
* ServileSnarker: She didn't need to be one to be Gustavo's assistant, but it sure helps!
* StraightMan: Mostly overruled when the boys and Gustavo enter crazy mode.

!!Arthur Griffin
--> Played by Matt Riedy
CEO of the RCM CBT Globalnet Sanyoid Corporation, which also owns Rocque Records.

* {{Cloudcuckoolander}}: Mercedes once said her father loved Lolo, the chimp, more than her.
** And the chimp was the ''music inspector''.
*** Later Griffin demotes Lolo to Nuclear Missiles inspector.
* CorruptCorporateExecutive: Even played with in Big Time Halloween. His supernatural alter ego was basically himself, but with a [[BigRedDevil red suit]].
*** So, you're saying that ''[[Creator/DanaCarvey he could be... Satan?]]'' [[TakeThat Well - it is the music industry...]]
* DotingParent: He spoiled Mercedes a lot.
* HeelFaceRevolvingDoor: And around and around and around he goes! One episode he can be the happy cuckoolander boss, and the next episode he may want to close Roque Records unless they make more money for him.
* JerkWithAHeartOfGold: It comes and goes.

!!Freight Train
--> Played by Stephen Keys
Gustavos's henchman in charge of "making people do what I say", mainly carrying the guys back to the studio when Gustavo requires.

* TheBigGuy: Of Gustavo's employees. He is "the guy who makes people do as Gustavo says". Carlos occasionally enjoys the free rides on his shoulder.
* GentleGiant: Despite being the big bodyguard in charge of dragging the boys to work, he is very insightful and well mannered, [[HotBlooded unlike Gustavo]].
* OnlyKnownByTheirNickname: They only refer to him as "Freight Train", which is very unlikely to be his real name.
* RealMenWearPink: Despite his intimidating appearance, he admits he would be touched by the new song if he were a girl.

!!Mercedes Griffin

* ConsummateLiar: She lied the boys about being the musical-hit advisor so she could date each of them. When she actually tells her dad the truth, Griffin's first reaction is to verify with the others.

* {{Expy}}: Of [[Series/NedsDeclassifiedSchoolSurvivalGuide Missy Meany]]. Justified as the same actress plays both characters.
* FreudianExcuse: She attributes her mean and spoiled attitude to ParentalNeglect, as she even states her dad loves his chimp more than her.
* ItsAllAboutMe: The reason she did not pick James as her boyfriend was because she would never date a guy prettier than her. James pretty much was happy with that.
* JerkWithAHeartOfGold: After her outburst when Kendall tells her off, she returns to apologise and make mends by telling them how Griffin could pick them for the album release.

[[folder:Recurring Characters]]

* TheDitz: He is very absent minded on duty.
* TheMentor: He sees a lot of potential in Logan as a future doctor and tries to convince him to work full time on the career (which also meant that he would have less time for the band). After that, he still gets along well with Logan.

!!Jenny Tinkler
--> Played by Sammy Jay Wren
A girl from Minnesota who was also in the boys' school and attended Gustavo's audition. Her dream is to be "the next [[Music/NoDoubt Gwen Stefani]]". She is also known to be accident prone on a whole other level.

* BornUnlucky: The boys know Jenny has been like this since kindergarten. James needed stitches in his arm ''for a papercut''.
* BritishRockStar: She becomes the new lead singer of Death Smash because of her ''destructive talent'' and potential as the new FaceOfTheBand.
* TheBusCameBack[=/=]AscendedExtra: She started as a minor character who was rejected in the auditions of the pilot. She returns a season later in "Big Time Fans", as Carlos promised to help her in her singing career.
* CuteClumsyGirl: Everywhere she goes, something is going to break or someone is going to the hospital.
** Even after setting the building on fire '''''four times''''', the guys find it impossible to reject her and stomp on her dream.
* LargeHam: Especially when she sings.
* MinnesotaNice: She is as cute and nice as she is lethal.
* TheSmurfettePrinciple: When she joins Death Smash. The other two members are big badass rockers (who secretly hated their original leader for making them smash guitars and fake their accents).

!!Carlos' parents
--> Played by Erik Estrada and Jill-Michele Melean
Carlos' parents. Both of them visit Carlos at Palm Woods, although in separate episodes. They have a very close relationship. Carlos' dad is a police officer and takes his job very seriously, maybe a little too much.

* BumblingDad: He takes his job very seriously, even applying it to his son's daily tasks.
* GoodCopBadCop: Although Officer Garcia is always missing a good-cop partner.
* LikeFatherLikeSon: Both of them are impulsive, reckless and carry their helmets everywhere.
* PapaWolf: Back when Carlos was little, Officer Garcia lined up an interrogation session to find out who stole Carlos' lollipop, prompting the guilty kid to faint under the pressure.

!!James' parents
--> Played by Brian [=McGovern=] and Lisa Rina

* AlmightyMom[=/=]EvilMatriarch: To the point where the only time she didn't get what she planned was because the other three moms teamed against her.
** She even got the boys to enroll to ballet instead of hockey and got them to call Logan by that name rather than by his given name, Hortense (this one turned out to be for good).
* TheBaroness: She's known as "Estee Lauder of the Midwest" for being a prominent makeup mogul.
* MayDecemberRomance: James tells his father got remarried to a 19-year-old, and that's why his mother won't talk to him anymore.
* MyBelovedSmother: Very much.
* {{Tsundere}}: His mother's excuse for taking James with her is because she plans for him to take over the business, but in reality she just misses him a lot.


Lucy's ex-boyfriend from Georgia. Shortly before she moved to California, she broke up with him when she discovered he was cheating on her.
* GoldDigger: A possible explanation as to why he wanted Lucy back.
* TheRival: Briefly to Kendall.

[[folder:Movie Characters]]

!!Simon Lane

A rogue secret agent, who stole an anti-gravity device from Atticus Moon, setting the events of the movie in motion. He is unconscious for most of the movie.

* {{Expy}}: [[Film/JamesBond Do I have to say it?]]
* HeroWithBadPublicity: Went rogue and has been hunted down like a criminal by the time the movie begins.

!!Penny Lane

A spy in training, and Simon's daughter. When her father goes rogue, she attempts to clear his name and runs into the boys along the way.

!!Atticus Moon

One of the richest men in England, who blames the worlds problems on international disagreements and thus wants to start a revolution.

* ArchEnemy: To Simon Lane.
* {{Expy}}: Of Bond Villains, but let's face it, he's no [[Film/AustinPowers Dr. Evil]].
* [[spoiler:KarmicDeath: Implied. [[FridgeHorror If you give the logical circumstances, if the beetle releases him, he'd fall to his death; if not, he'd likely float out of the Earth's atmosphere]]. [[FridgeBrilliance Then again]], TheMovie is a homage to James Bond films and how many Bond villains do you know that live?]]
* KnightOfCerebus: Doesn't act like one but let's analyze -- his evil plan would have resulted in countless deaths and/or injuries to people around the world, his henchmen appeared to have ''guns'', and [[FridgeHorror we don't know what he would've done to Katie after he abducted her]]. [[spoiler: Also let's come to terms with the possibility that he and some of his henchmen were some of the first villains to die on this show.]]
** In addition, he's the first ''real'' threat the show has seen. Hawk may have been a nasty person, but he was just threatening a boy band. Moon? He threatened the ''entire'' world.
* RightHandCat: Played for laughs as he always wants a cat in his hands at the right moment and his henchmen apparently have a cat on hand at all times.
* SpoiledBrat: Acts like one at times
--->'''Atticus Moon''': I always get what I want.
* VillainWithGoodPublicity: At first.

!! Alexa Vega

* ActionGirl: Who later becomes an ActionGirlfriend.
* AdamWesting: She's an actual spy in this universe.
