List of Malcolm in the Middle characters

Malcolm, portrayed by Frankie Muniz (150 episodes), is the main protagonist and occasional narrator of the series. He is five years younger than his oldest brother Francis, one year younger than his older brother Reese, five years older than his younger brother Dewey, and about 14 years older than his youngest brother Jamie. In the first episode of the series, he is discovered to be a child prodigy and immediately moved from his regular class into the "Krelboynes", a class for gifted students. Despite his high intelligence, he still gets into mischief either alongside or working against his brothers (in particular, Reese), although he becomes more self-absorbed and egotistical in the later seasons as he goes through puberty. According to Hal, in "Stock Car Races" (season 1), Malcolm was named after Hal's favorite Stock Car Racer, Rusty Malcolm, although he had previously argued with Lois about giving the name to Francis and Reese. Malcolm, like Reese, is not very popular. However, he has had a number of girlfriends during the series run. Even though he is very intelligent, Malcolm has a short temper, can be easily manipulated and also has problems containing his opinion about himself. Malcolm also occasionally serves as the voice of reason, and does have a conscience, for instance, despite emotionally manipulating a grieving Hal to buy him a car in the episode "Hal Grieves," when the time comes to make the purchase he finds he can't go through with it. In the series finale, it is revealed that Lois intended him to have a hard life, knowing that he is destined to assume the role of President of the United States; she wants him to remember where he came from to get there and try to help families like his own when he assumes the office. Malcolm eventually comes to terms with his future, after being unable to tell Lois he cannot do it. In the series finale, Malcolm begins taking classes at Harvard University. Throughout the series, Malcolm frequently breaks the fourth wall and talks to the viewer about either the current situation or giving exposition about past events.[2]

Reese, played by Justin Berfield (151 episodes), is the second oldest of the brothers. He is four years younger than his older brother Francis, one year older than his younger brother Malcolm, six years older than his younger brother Dewey, and about 15 years older than his youngest brother Jamie. It was revealed in the episode "Flashback", in season 2, that Reese has been vicious from the womb, so vicious in fact that when he kept kicking Lois during labor, she pushed him out by force. A complete moron from birth, Reese is the worst-behaved of the brothers. Reese is inclined to beat up the Krelboynes. He is intimidated by certain students, including Ira, a dumb jock at school. Despite his violent, idiotic nature, Reese is a culinary prodigy, after finding that he has a talent and genuine love for cooking and baking. He is also the favorite grandson of his grandmother Ida, who taught him the importance of having patsies. In the series finale, Reese moves in with Craig Feldspar and is a janitor at his alma mater North High.[2]

Dewey, played by Erik Per Sullivan (151 episodes), is portrayed as being quieter and more inclined to the arts than his brothers. He soon finds he is a musical prodigy, and as the series goes on he becomes more caring and thoughtful especially in regards to his younger brother Jamie, whom he decides not to bully like he was by Malcolm and Reese. Lois remarks at one point that unlike Malcolm, who would have to work hard to achieve success, Dewey would have success handed to him. Dewey joins the Buseys, a class for the emotionally disturbed, by mistake and ends up becoming their unofficial teacher. He ended up caring for his fellow students so much that, when the mistake was uncovered, he feigned severe emotional problems so he could remain. In the final few seasons, Dewey becomes increasingly bitter towards his parents due to them overlooking him throughout his childhood and neglecting his interests. Because of this, he forces them to give Jamie the childhood he never had. In the last episode, he and Jamie (the only other remaining brother living at home) continued the tradition of causing havoc all over the house.[2]

Lois, played by Jane Kaczmarek (146 episodes), is Francis, Reese, Malcolm, Dewey, and Jamie's angry and temperamental mother. She is an overbearing control freak despised by the neighbors to the point that they refuse to invite her to their gatherings, revealed in "Mono". Unlike Malcolm, Lois is not bothered by it and tries her best to blend in with it. She was revealed to be a charming and a nurturing mother while Francis was little, but toughened up. When she became overbearing and a tough bully, it did not help Francis or the other boys to behave, but she made it worse. She is also always stubbornly right, to the point of being unable to say that she was wrong. It was also shown that she is overbearing and mad as a result of her sons' bad behavior, and not her pure hate. Her unfairness and behavior also come from her miserable childhood, living with tough mother Ida and uncaring father Victor, both of whom favored her younger sister, Susan. Lois and Susan would later have a serious falling out after it is revealed that Hal was originally Susan's boyfriend. She is a pushy academic mother and in the series finale, it is revealed that she is trying to groom Malcolm to become President of the United States. The finale also reveals that she is pregnant again. Lois is usually seen driving the family's early 1990s Dodge Grand Caravan.[2]

Hal, played by Bryan Cranston (151 episodes), is the father of the family. Though relaxed in his parenting when compared to Lois, Hal has shown that he can slide into a disciplinarian when confronted by the boys' bad behavior. He used to be like his sons, especially Francis, until he married Lois and she nurtured him. He comes from a wealthy family who resent his choice to marry Lois over Susan (an action also shared by Victor and Ida). Hal has a hard time making good decisions, which he often deferred to Lois. Despite the fact many of the neighbors hate his family and especially Lois, Hal blends in well with them. He loves Lois more than she loves him, never even thinking about other women. He is also very scared of her, even more than the boys are, which is why he often bribes their sons to take the fall for his wrongdoings. He is very devoted to Lois and willing to give the boys punishment they deserve that Lois gives them. Lois is usually head of the household and Hal is second-in-command. He is very neurotic and has a slight obsessive-compulsive disorder, and also enjoys unusual hobbies. Hal is also a sex addict, as revealed in the episode "Forbidden Girlfriend" when Lois is taking medication and is unable to have sex for an entire week. It is mentioned again in the episode "Poker 2" when Hal tells his friends he has sex 14 times per week. It was also revealed that Hal was a chain smoker before quitting the habit. Hal's best friend is Abe Kenarban. Hal works in a lower management job in a corporation that he always hated. He used to be an executive and got demoted when he mouths off to his boss in the season 2 finale. Hal is usually seen driving a late 1980s to early 1990s Dodge Dynasty.[2]

Francis, played by Christopher Kennedy Masterson (118 episodes), is the oldest of the brothers, whom Malcolm often looks up to. According to the season 1 episodes "Sleepover" and "The Bots and the Bees", Francis was a breech birth. The season 2 episode "Flashback" reveals that Lois was in labor with him during her and Hal's wedding. A rebel from birth, showing signs of attention deficit hyperactivity disorder and conduct disorder, Francis was exiled to the Marlin Academy military school by Lois for his behavior. By season 3, he emancipates himself to run away from the academy to work in Alaska, incurring his mother's wrath. Shortly after moving to Alaska, he marries a local woman about one year older than him named Piama, who had a previous brief marriage, though Lois disapproves of Francis marrying her. During the fourth and fifth season, Francis works at a dude ranch owned by Otto Mannkusser and his wife Gretchen. Francis is mostly absent for the last two seasons, but, in the series finale, Hal discovers that he has taken a job with Amerysis Industries, a large corporation where Francis works in a cubicle and inputs numbers into a computer, and is also still happily married to Piama. Although Francis is happy with the job, he has no intention of telling Lois about it, as he enjoys torturing her by telling her that he is still unemployed.[2]

Caroline Miller, played by Catherine Lloyd Burns (15 episodes), is the primary teacher of Malcolm's "Krelboyne" class in the first two seasons. She is shown to be overly-earnest as well as to adore Malcolm. In season 1, she is included as part of the main cast, but in season 2, is a recurring character. In season 2, she is shown to be pregnant until she gives birth to her baby in the parking lot. After her baby was born, she quit teaching. She was never seen or mentioned again after season 2.[2]

• Stevie Kenarban, played by Craig Lamar Traylor (56 episodes), is Malcolm's best friend and classmate. He uses a wheelchair and was born with one lung, requiring him to speak slowly and take deep breaths between words. Though Malcolm is initially upset when Lois arranges a "playdate" for him and Stevie in the pilot episode, the boys immediately find common ground, particularly their love of comic books, and become friends. His parents are very overprotective of him, although Stevie displays in many episodes that he lives very comfortably with his disability and even has a dark sense of humor about it.[3]
• Abe Kenarban, played by Gary Anthony Williams (19 episodes), is Stevie's father and Kitty's husband, and a close family friend of both Lois and particularly Hal. Abe is initially depicted as cowardly and dependent on Kitty's guidance (which he attributes to his upbringing, having been raised by his grandmother and four spinster aunts). However he ultimately becomes more self-reliant after Kitty's departure. Despite this, Abe is more than willing to take Kitty back after her return, going as far as to harbor resentment towards Lois after she criticized Kitty's decision to leave.[4]
• Kitty Kenarban, played by Merrin Dungey (5 episodes), is Stevie's mother and Abe's wife. Because of Dungey's commitment to the ABC series Alias, Kitty remains unseen for much of the series, apparently due to her abandoning her husband and son, which briefly throws Stevie into a deep depression. She returns once in the season 6 episode "Kitty's Back".[2]

• Lionel Herkabe, played by Chris Eigeman (8 episodes), is the main antagonist of the series. He was first introduced in Season 3 as the Krelboynes' teacher after Caroline leaves. A Krelboyne himself in middle school, he was forced into a teaching career after losing his millions in a failed dot-com company. He is portrayed as an evil and conniving man who thrives on psychological warfare and making his students suffer. Malcolm especially is a threat to him and quickly becomes his nemesis at school, even blackmailing North High's principal, Block (before Hodges took over), into hiring him as vice principal when Malcolm enrolls there. Mr. Herkabe also intensely enjoys humiliating Reese to antagonize Malcolm more. However, Herkabe's arrogance in confessing that he skipped gym his senior year and lied about not taking the course was brought to light which leads to Mr. Hodges revoking his GPA Award in the season 7 episode "Malcolm Defends Reese". He is last seen when Reese tosses dodgeballs at him in P.E. class as an attempt to reclaim his title.[5]
• Cynthia Sanders, played by Tania Raymonde (4 episodes), is one of Malcolm's classmates. She has a very extensive vocabulary, but has a difficult time making friends. Depicted as relatively cheerful, Cynthia becomes one of Malcolm's earliest crushes on the show, although a relationship never develops. Cynthia is last seen claiming to never have sex with Malcolm again (which never happened in the first place) to snap him out of a recent funk and keep him from pulling a prank meant to get him sent away like Francis.[2]
• Lloyd Jensen, played by Evan Matthew Cohen (25 episodes), is one of Malcolm's "Krelboyne" classmates who recurs throughout the series. He frequently worries about random small things, gets hurt, and falls victim to bullies. He also has an effeminate personality.
• Dabney Hooper, played by Kyle Sullivan (24 episodes), is one of Malcolm's "Krelboyne" classmates who recurs throughout the series. Often depicted as the weakest and most cowardly of the group, his overbearing mother almost completely controls his life, until his last appearance where his ability to release his anger towards his mother results in him immediately developing a tougher persona.
• Flora Mayesh, played by Kristin Quick (15 episodes), is one of Malcolm's other "Krelboyne" classmates. Flora was mostly just a background character and rarely had dialogue and was therefore not in the credits for 12 of her episodes.
• "Eraserhead" (real name: Kyle), played by Will Jennings (12 episodes), is one of Malcolm's "Krelboyne" classmates who recurs throughout early episodes of the series.
• Kevin, played by Victor Z. Isaac (5 episodes), is one of Malcolm's "Krelboyne" classmates who recurs throughout later episodes of the series.

• Piama Tananahaakna, played by Emy Coligado (29 episodes), is Francis' wife whom he met and married off-screen during his year in Alaska.[6] Piama is about a year older than Francis, and before him, Piama had previously been married briefly. Primarily due to her being brought home under volatile circumstances, in which Francis (while still a minor, although emancipated) shocked the family with news of the marriage and thus disrupting Hal's birthday party, Lois dislikes Piama from her introduction in the third season and into the fourth. However, after an embarrassing encounter with her wealthy in-laws, Lois starts to respect Piama more. Piama is against having children until the series finale, when one of Reese's pranks goes awry.
• Victor Welker and Ida Kenzel-Welker, played by Robert Loggia (1 episode) and Cloris Leachman (11 episodes) respectively, are Lois' parents of a German-Serb background. Victor dies some time before the events of the season two episode "Christmas", in which Ida is widowed. Ida harbors a strong dislike for both Francis and Lois, evident for the way she has been treated by them. She favors Reese, which allows him to love her. Ida belittles Malcolm for being weak in not standing up against his mother and largely ignores Dewey (although she did, on one occasion, save him from being hit by a car, causing her to lose a leg). Ida harbored resentment towards Victor's secret other family for stealing what was rightfully hers, until Lois discovered that she is not blood related to Victor (and possibly Susan as well) and abandoned Ida. Ida acknowledged that her life growing up in Croatia under the Ustaše was difficult, possibly due to the Ustaše's policies. This and the fact that her brother, who remained in Croatia, is called Miloš suggest that she belongs to the Serb Minority in Croatia. This is supported by Ida celebrating St. Grotus day, equal to a Serb tradition known as Slava when Serb families glorify one's family patron saint.[7]
• Raduca, played by Rheagan Wallace, is Reese's wife for two episodes during season 7.[8]
• Jamie, played by identical twin brothers James and Lukas Rodriguez (35 episodes), is the youngest child born to Hal and Lois. He is the only brother to have beaten Lois in her own game, bordering to attacking her (though Reese was mostly responsible for feeding him soda). Like Malcolm and Dewey, Jamie is intelligent, as evidenced when he tricks Reese into taking a marker after coloring part of a wall.[9]

• Craig Feldspar, portrayed by David Anthony Higgins (39 episodes), is Lois' co-worker at the Lucky Aide. He is a hopeless romantic, and has unrequited feelings for Lois. He is very childish and is a coward. He plays the ukulele and the banjo, and he sings in a countertenor voice. By the end of the series, Craig becomes Reese's roommate.[10]

• Commandant Edwin Spangler, played by Daniel von Bargen (16 episodes), is the military veteran in charge of the cadets at Marlin Academy. A retired United States Air Force general who has never experienced frontline combat, he has a contentious relationship with the rebellious Francis throughout his entire stay at the Academy, although the two sometimes show a deep sympathy for the other's emotional scarring from family. He wears an eye patch and has a hook for a hand, although it is never fully explained why. Before Francis leaves Marlin Academy, Spangler tells Francis that bullying him gave him a sense of purpose and would have retired without him, then gives him a ceremonial sword, which Francis accidentally uses to cut off Spangler's remaining hand. Later in the third season, Spangler tracks Francis to Alaska, having been fired for drinking on the job, and still feels depressed with no one to bully. Francis gets him a job at the Snow Haven Retirement Home, where he has free rein to bully the elderly.[10]
• Cadet Eric Hansen, played by Eric Nenninger (28 episodes), one of Francis' friends and classmates from Marlin Academy. Francis accompanies Eric in his plan to abandon the Academy to find well-paying labor work in Alaska. At the end of season three, Eric is seen for the final time being left by Francis to hitchhike home.[10]

With Dewey's help, Ira got his revenge on Reese for his prank and using Billy by simply beating him up. He returns briefly in Season 5's "Malcolm Films Reese" who is among the students in humiliation and in "Reese's Apartment" when Malcolm is tutoring Ira and help get him a passing grade in his classes so he can keep his spot on the North High School football team. Unlike Reese, Ira has more respect for Malcolm.
