* BunnyEarsLawyer
* ButtMonkey: Sometimes.
* ChaoticStupid: but explicitly [[AvertedTrope NOT]] StupidEvil.
* {{Cloudcuckoolander}}
* CrouchingMoronHiddenBadass
* DumbassTeenageSon
* EvenEvilHasStandards: Yeah, he's a bully, but he being an "alpha-bully" he declared the disabled Stevie "off-limits" for bullies (inlcluding him). In fact, making sure the other bullies respected his standards eventually became his reason to retain his alpha-bully status.
** Even when he finally snaps and decides to beat up Stevie, Reese completely numbs and weakens his own legs to make it a "fair fight."
** Also, while he makes other nerds do his homework for him, he doesn't want to interfere with their weekends.
* FoolishSiblingResponsibleSibling: The Foolish to Malcolm's Responsible.
* ForTheEvulz: He likes to cause chaos and destruction just for the fun of it.

* NoMatterHowMuchIBeg

* ThePrankster
* ProperlyParanoid
* ScrewySquirrel

* SupremeChef: Would have won the cook off hands-down if he hadn't [[DickDastardlyStopsToCheat decided to cheat anyway]]. And let's not forget his [[FoodPorn Thanksgiving spread]].
* TooDumbToLive: His bread and butter.
** A good example? After Malcolm give him a book report guaranteed to be an A, his (then) girlfriend, Alison, realizes that ''she'' forgot to do hers, lamenting on how she can't afford another F. Reese's solution? ''Tearing the report in half'', insuring that "now [they'll] both get Cs".
* TookALevelInKindness: He starts to be a more decent person in later seasons.
** He actually describes a voice that has been getting louder telling him not to do stupid things.
* TrashTheSet


->'''Played by''': Erik Per Sullivan

!!The Tropes that are associated with this character are:
* AnnoyingYoungerSibling
* BewareTheNiceOnes
* BigBrotherWorship: For Francis (well, sort of. They barely interacted before he was deported to Military School, so he doesn't have as much personal worship as Malcolm and Reese).
* BitchInSheepsClothing: He's possibly the most devious family member.
* [[CallingTheOldManOut Calling The Parents Out]]: He frequently manages to get revenge against Hal and Lois whenever they neglect him or treat him unfairly. Hal forgot his birthday led to Dewey publicly shaming him in front of every single attendee at a Bridal expo. Lois saying she couldn't get a vital component to a science experiment (which led to Dewey failing) resulted in Dewey {{Gaslighting}} her. And for the most part, he actually gets away with it.
* CharacterDevelopment: Undergoes this more than any other character (with the possible exception of Francis). Over the course of the series, he evolves from a ditzy Cloudcuckoolander with an [[MrImagination overactive imagination]] into a WiseBeyondHisYears child prodigy who is just as smart as (if not moreso than) Malcolm. [[JustifiedTrope Justified]], given that he ages through the most critical period of child development during the time course of the series (going from a pre-adolescent child in the pilot to a young teenager in the finale).
* TheChessmaster: He shows shades of this in later seasons.
* {{Cloudcuckoolander}}: Early in the series.
* CreepyChild
* CrouchingMoronHiddenBadass
* DeadpanSnarker
* DitzyGenius
* GenderBender
* GuileHero
* IgnoredEpiphany: Tried to explain one to Reese and Malcolm in ''Buseys Run Away''. After finally being put in a normal classroom, Dewey lacks the drive to commit heinous pranks with his brothers like he used to. Therefore, he starts bonding with Lois while Malcolm and Reese keep getting punished. They don't understand what's going on, and Dewey tries to explain that the reason Lois is acting so nice to him, is that he hasn't done anything stupid or destructive, so she hasn't needed to punish him. "It's not her, it's us." His brothers didn't get what he was saying and automatically assumed he's become Lois' spy.
* KarmicTrickster
* KnightInSourArmor <--> PragmaticHero: Depends on the episode.
* ManipulativeBastard: Is a master at playing head games; even manages to drive ''Lois'' insane in one episode.
* MouthyKid
* MrImagination
* ObfuscatingStupidity
* OnlySaneMan: Later in the series.
* PapaWolf: Dewey will do everything in his power to protect and nurture the kids in the special classroom, because no one else is willing to.
** Also to his younger brother, even tricking his own parents to ensure that the younger brother gets the attention from his parents that he himself never got because they were always to busy dealing with their ,pre troublesome kids.
* TheStoic
* TooDumbToLive: In a flashback: while one of his brothers is cranking the pedal of an overturned bicycle, he takes a bite out of the spinning wheel.
* WellIntentionedExtremist: Was willing to do anything to ensure that his brother got even a decent childhood, even if it meant tricking or humiliating his parents in the process.
* WickedCultured: Dewey is clearly the second most intelligent member of his family, the most cultured and sophisticated, and arguably the most devious.
** Lois realises it's likely Dewey that was GasLighting her because she knew because Malcolm didn't have the patience he did.
* WiseBeyondTheirYears


->'''Played by''': Christopher Kennedy Masterson

!!The Tropes that are associated with this character are:
* AesopAmnesia: In season 6, after being fired, he's back to what he was during the first few seasons.
* AxCrazy: Before being sent to military school.
* BigBrotherBully : He admits to Dewey that he tortured them, stole their toys, locked them in a closet, and apparently cut Reese on the shoulder deep enough to leave a scar with a Bayonet.
* BigBrotherMentor: He assumes more this role throughout the series, though he can still have his BigBrotherBully moments from time to time.
* BlondGuysAreEvil
* [[CallingTheOldManOut Calling The Old Lady Out]]: Frequently rebels and insults Lois, and it is heavily implied that it is for no other reason than just to spite her.
** His female equivalent, Frances, is similar, although her hate is more directed towards her ''dad'', blaming him for none of her marriages working out.
* CharacterDevelopment: He becomes a lot more responsible as the series progress. In fact, many later episodes deal with how he fights his insane impulses (like when he warned Reese against collecting toilet rings from a dump like he did as a teen but ended up trying to beat Reese's record.) By the end, he is married and in a stable office job that, unlike Hal, he likes. It's possible though that Hal did like his job when he was the same age as Francis, but grew to resent it.
* TheChewToy: Especially in earlier seasons.
* CoolBigBro: He's seen this way by Malcolm, Reese and Dewey.
* EnfantTerrible: In the episode ''Lois fights Jamie'', in flashback form, we learn that Francis was absolutely horrible as a toddler. Probably the worst act he committed was using the last of the china to pour a flammable substance (lighter fluid) onto his teddy bear, and then set it on fire, which also resulted in Lois becoming the mother she currently is. It's also hinted that Lois's attempt at loving Francis (by placing the already burning teddy bear in the fireplace, burning her hand in the process) was a painful memory for him, given his reaction when he tells Lois this.
* EvenEvilHasStandards: He refused to fight against his boss, Lavernia, because she is a woman -- [[spoiler:until she ended up mocking his mother. He then fights back and the fight ended with a draw]].
* FourthDateMarriage: He and Piama knew each other a very short time before getting married. Slightly deconstructed when there are several moments where they wonder whether their relationship can work out, but ultimately they remain together.
* FreeTheFrogs
* GenderBender: In the episode where Lois imagines if his four sons were girls. Notably, Christopher ''also'' plays girl Francis.
* GenerationXerox
* GlobalIgnorance
* ForTheEvulz: Francis basically committed his delinquent behavior either to spite his mother (who told him not to do them) or just for the heck of it.
* HighSchoolHustler
* {{Jerkass}}
** JerkWithAHeartOfGold
* LackOfEmpathy: As evidenced in the BigBrotherBully trope, he did several heinous things, and he implies that this is what being a good brother is all about. Also, he does very terrible and destructive things during his revolts against his parents and is implied to have absolutely no remorse for any people he hurt as a result, and he actually [[ArsonMurderAndJaywalking ends up in emotional pain when he has to tell Lois how much she actually shaped his life in a memory that should be a pretty heartwarming memory]].
* LaserGuidedKarma
* MrFanservice
* NeverMyFault: He tries to pin (almost) all of his faults on his mother. In fact, he was legitimately stumped when his C.O. told him to think of one thing that he did wrong that he doesn't blame on his mother. The only time he actually did admit to wrongdoing without blaming his mother or anyone else was when he admitted that it was his fault that his brothers turned out the way they did.
* NominalHero
* NotSoDifferent
* OutOfFocus: In the last two seasons.
* PlayingWithFire: This is what causes Lois to attempt to pull a complete 180 on her raising methods (he nearly set his teddy bear on fire, and the fact that he was pouring gasoline on it and then attempting to light it implied that he was doing so deliberately)
* RebelliousSpirit
* ScreamsLikeALittleGirl
* TheSociopath
* TooDumbToLive: Shown in a flashback throwing a knife up in the air then extending his hand out to catch it.
* TooKinkyToTorture: While attending military school, he was forced into a hazing ritual by the other students. NONE of their humiliations or scare tactics had any effect on him. He cites that being on the receiving end of Lois' child raising-tactics him is the reason for this. [[CrowningMomentofFunny The students then decide to use Lois for inspiration.]]
* TroublingUnchildlikeBehaviour: As a toddler, Francis attempted to douse his teddy bear with gasoline and then set it on fire before Lois intervened. Later, as a child, he had locked his parents out of the car while his mom was going into labor, and he also frequently tortured his brothers, stole their toys, locked them in a closet, and at one point scarred Reese with a bayonet.
* WouldntHitAGirl: Played straight, then subverted. See EvenEvilHasStandards.

->'''Played by''': James and Lukas Rodriguez

!!The Tropes that are associated with this character are:
* EnfantTerrible: He's so bad that he actually manages to break his mother's spirit.
* TroublingUnchildlikeBehavior: From stealing from the neighbors, to nearly killing his mother, he's proven himself to be as big as a threat as his brothers.

->'''Played by''': Jane Kaczmarek

!!The Tropes that are associated with this character are:
* ActionMom
* AntiHero: An UnscrupulousHero at her best and a NominalHero at her worst.
* AntiVillain: [[SlidingScaleOfAntiVillains Type II]], her mother and her first son eventually led her to this.
* AbusiveParents: Aside from the well known FinancialAbuse, she is also implied to be physically abusive, given what Francis commented on what things his brothers should resist in regards to possible methods of extracting who burned her dress, and his resistance to a hazing from a cult on the military school resulted in their adopting Lois's methods. Of course, then again, given his obvious hatred for his mother, it's possible that he either lied about it or led himself to believe it.
** She originally intended to subvert it, as she intended to make her household lax of rules specifically because she didn't want to have her children go through the life she herself had to put up with Ida. Unfortunately, Francis as a child proved how faulty that line of thought was when he did several bad things which came to a halt when he attempted to douse his teddy bear with gasoline and set it on fire.
** In addition, she herself was a victim of parental abuse via her mother. It is implied to be far, far worse than anything she puts her own kids through, and unlike Lois (who as described bellow acts this way in order to keep her boys safe), doesn't do it to protect Lois, she's just a horrible, spiteful old woman.
** Following the incident with the teddy bear mentioned above, Lois had calmly and firmly describe to baby Francis that from that point on she would do everything in her power to keep him and any other child she might have as safe as possible, regardless as to whether or not her kids would hate her for it. Lois knows very well how her kids feel about her parenting, but she legitimately does not care because she's willing to live with them hating her as long as they're safe and alive.
* AxCrazy: Not to Francis's or Reese's level, but she does have her moments.
* BecauseYouCanCope
* BestYearsOfYourLife
* ControlFreak: To the point where a random police officer calls her out on it, along with a Resident Advisor at a school she was visiting with Malcolm, though the RA admitted he was one too.
* DarkAndTroubledPast
* {{Determinator}}: After Reese is sent to Afghanistan she crosses half the earth in order to bring him back home.
* DisproportionateRetribution: Played frequently and famously as a major character flaw, such examples would be in ''Evacuation'' (She grounds Malcolm for being late home from studying at the library, while insisting on continuing the punishment during a neighborhood-wide evacuation) and ''Health Scare'' (where Lois grounds Malcolm and Reese for a week for simply tracking mud on the kitchen floor, even after the promised to clean it up, though it's somewhat justified as she was distracted by a potentially terminal condition Hal had).
* EvilMatriarch: Not to Ida's level, but she does have her moments.
* FreudianExcuse
* FinancialAbuse: Towards Malcolm.
* HairTriggerTemper
* HeroicComedicSociopath: In "Lois Strikes Back".
* {{Hypocrite}}: In the episode she gets Malcom a job at her store, in a variety of different way. Malcolm calls her out on it repeatedly given how strict and principled she is at home, but she is utterly remorseless about it, spinning it as him learning harsh lessons about life.
* {{Jerkass}}
** JerkWithAHeartOfGold: In earlier episodes, then she started to become more like a {{Jerkass}} in season 3, and reserves it to Reese in seasons 6 and 7.
* JuryDuty
* KarmaHoudini: Occasionally, but there are other times (i.e. ''Evacuation'') where she gets her comeuppance.
* KarmicTrickster
* KnightTemplarParent
* LackOfEmpathy: Towards Malcolm, to some extent.
* MamaBear: Toward Reese.
* ManipulativeBitch
* MasculineGirlFeminineBoy: Masculine Girl to Hal's Feminine Boy.
* MyBelovedSmother: To Malcolm and Francis.
* ParentalFavoritism: Somewhat, towards Reese. She explains that this is because she knows Malcolm is smart enough to get out of difficult situations and Reese is the one who needs help.
* PitbullDatesPuppy: The "Pitbull" in her relationship with Hal.
* RightForTheWrongReasons: She's usually right about something but her line of reasoning for something being wrong is that things can't be that way because [[TautologicalTemplar that would require her doing something wrong.]]
* SanitySlippage: Happens in the "Reese Joins the Army" trilogy, but gets over with it at the end of the second part.
* SociopathicHero
* TookALevelInKindness: Towards Reese, and only Reese.
* {{Tsundere}}: Type A.
* TheUnfavourite: Ida always liked Susan better.
* TheUnfettered
* UnsympatheticComedyProtagonist

* FinancialAbuse: Towards Malcolm.
* HenpeckedHusband
* LaserGuidedKarma
* ManChild
* MasculineGirlFeminineBoy: Feminine Boy to Lois' Masculine Girl.
* NakedPeopleAreFunny: Quite frequently seen in his underwear or naked for this reason.
* NervousWreck
* OneHourWorkWeek: Mostly averted though he is later revealed to have not worked on a friday in fifteen years. Possibly justified by how corrupt the company is and unimportant Hal's contribution is.
* PapaWolf: In the episode dealing with an alternate timeline where Lois had daughters instead of sons, Hal, although overweight, is also extremely protective of his daughters, although his daughters aren't appreciative of his efforts.
* PitbullDatesPuppy: The "Puppy" in his relationship with Lois.
* ScreamsLikeALittleGirl
* TakeAThirdOption
* WhatExactlyIsHisJob?: His exact job is somewhat vague though it is known that he works for a large corrupt company and works out of a cubicle. He views it as unimportant and notes he could be replaced easily.

!!Stevie Kenarban
->'''Played by''': Craig Lamar Traylor

!!The Tropes that are associated with this character are:
* BewareTheNiceOnes
* BlackAndNerdy
* BlackBestFriend
* CorruptTheCutie / TookALevelInJerkass: Starts off the series as a rather innocent kid (thanks to over protective parents), but then he started hanging out with Malcolm and his family. Downplayed somewhat, however--from his first appearance he's willing to use his disabled status for a WoundedGazelleGambit
* DisabledSnarker
* GeniusCripple
* HandicappedBadass: He started out [[DisabledMeansHelpless as quite innocent and helpless]] but as the series progresses he becomes much more confident. He joined the schools wheelchair basketball team, uses his wheelchair as a weapon against bullies (by running them over) and was revealed as the badass street racer in one episode. Interestingly, a lot of this takes place after his Mom leaves, suggesting it was her over-protectivness that made him under confident.
* MissingMom
* OnlySaneMan
* TeenGenius
* VitriolicBestBuds: With Malcolm.

!!Dabney Hooper and Lloyd Jensen

->'''Played by''': HaydenPanettiere

!!The Tropes that are associated with this character are:
* TheChessmaster
* KarmaHoudini
* ManipulativeBitch: Her defining trait, at least to Malcolm and his brothers. [[spoiler:Lois, who is herself a ManipulativeBitch, is often able to see right through her.

* {{Meganekko}}
* ParentalNeglect: Her parents divorced and her father is in jail.
* ShipTease: With Malcolm, although it is often made ambiguous whether her feelings are genuine or simply more manipulations.

* EvilOldfolks
* ForTheEvulz
* '''{{JERKASS}}'''
** JerkWithAHeartOfJerk
* TheOldCountry: Ida and Victor apparently immigrated to the US from an unspecified {{Ruritania}} country in Eastern Europe.
* ParentalFavoritism: Towards Susan.
* PetTheDog: She had some sociopathic examples of esteem and self-sacrifice which help explain why Lois still cares more than she should about her.
* RacistGrandma: To the point where Lois and Francis make a plan with their (African-American) friends to get Ida out of their house so Lois could not have her there when she gives birth. It works too, until her waters break.
** This trope seems to be subverted when Ida reveals she's engaged to a man from Hong Kong, but it turns out she just wanted his money.

* TheSociopath
* [[spoiler:[[WickedStepmother Wicked Stepfather]]]]: [[spoiler:To Lois as it turned out, although it is left ambiguous whether or not he was aware of this fact.]]
* [[spoiler:YourCheatingHeart]]: [[spoiler:In "Victor's Other Family", it was revealed that he had married a Canadian woman (played by BettyWhite) and started a second family with her.]]

->'''Played by''': Christopher Lloyd

!!The Tropes associated with this character are:
* AbusiveParent: Not in the physical or verbal way, but the fact that he never accommodated to Hal's emotional needs, instead dodging any uncomfortable topics with humor and tickling.
* CallingTheOldManOut: Hal eventually does this while wearing a thick layer of coats so that Walter could not simply stop him by tickling him.
* {{Cloudcuckoolander}}
* CoolOldGuy
* KilledOffScreen: In "Hal Grieves."
* ParentalNeglect: See above.
* WackyParentSeriousChild: To Hal.

* StalkerWithACrush: Displays shades of this towards Lois. Although this was somewhat decreased over the series in favor of increasing his "annoying co-worker" characterization.

!!Abe and Kitty Kenarban
->'''Played by''': Gary Anthony Williams and Merrin Dungey

!!The Tropes that are associated with these characters are:

* BewareTheNiceOnes: Kitty is initially extremely meek and mild-mannered. After spending a night at dinner with Malcolm's family, she begins to emulate Lois' personality and becomes more vocal and confrontational.

* HookHand
* {{Jerkass}}
** He later becomes a JerkWithAHeartOfGold in the episode when Francis leaves the academy, acknowledging that he has developed a level of respect for his adversity.
* JerkassFacade: Later on in "Dewey's Dog," it is revealed that he is actually an extremely depressed and broken man and that tormenting the cadets at military school was the only joy and purpose he had in life.
* OldSoldier: Subverted. Despite his numerous amputations and scars, he has never actually served in a war (all of his injuries were non-combat related).
* WorthyOpponent: He eventually comes to see Francis as this.

->'''Played by''': Brenda Wehle

!!The Tropes associated with these characters are:
* AbsoluteCleavage: She wears an extremely low-cut shirt and never misses an opportunity to tell the males around her to stop staring at her cleavage.
* BadBoss: She not only works all of her employees like dogs but also charges them high fees for rent and other basic amenities (such as bedding and hot water) and will ''deduct money from their paychecks'' when they fail to keep up with it. She does this on purpose so they have to stay and work for her until they pay her off, which she makes sure they can't do until the logging is finished
* TheBaroness: Of the Rosa Klebb type.

* ConsultingMisterPuppet: When their estranged son was a child, Otto would discipline him with "Schlupi," a sock puppet. In Gretchen's words, "Schlupi could say all the things that Otto couldn't." Francis eventually gets Otto to reconnect with said son using Schlupi, and later uses it himself to call Lois and tell her that he realizes that she always had his best interests in mind.
* EuropeansAreKinky: Francis rewrites a scene from a porno he mistakenly allowed to be filmed at The Grotto to keep it clean for their sake, only to find out they were disappointed that the scene contained no sex.
* FunnyForeigner
* HappilyMarried
* HorribleJudgeOfCharacter: A RunningGag was Otto's painful gullibility and naivete. He would likely have fallen for numerous cons if not for Francis intervening and stopping him.
** [[spoiler:Ironically, Francis was eventually fired from The Grotto after being duped by one of these cons himself and losing the ranch's deposits.]]
* NiceGuy
* PetHeir: Otto included a cow at his will.
