Margaret Evelyn "Maggie" Simpson (born January 12, 1989), the pentagonist of The Simpsons, is the 1 year old, and youngest, child of Marge and Homer, and the baby sister to Bart and Lisa. She is often seen sucking on her pacifier, and, when she walks, she trips over her clothing and falls on her face. Because she rarely ever talks, Maggie is the least seen and heard in the Simpson family.

Personality
Despite being the only member of the Simpson family who hasn't learned how to speak, Maggie is in no way one-dimensional and has many different layers of personality. She appears to be somewhat detached from the rest of the Simpson Family and is described as "the forgotten Simpson" by Homer. When she, Bart and Lisa were shipped to a foster home (the Flanders) Maggie was the quickest to adapt and almost joined them until she noticed Marge. Perhaps Maggie's most strained relationship was with her father, Homer but due to his incredible laziness he neglected Maggie and when they do try to bond, Maggie sees her father as a kind of monster and actually tries to run away, she also developed a father-daughter relationship with Moe the bartender but the two still love each other and Maggie has more than once saved Homer's life. Not to mention she said her first word, "Daddy" after Homer tucked her in and kissed her goodnight meaning it's clear that she loves him as much as he does her.

Maggie's strongest relationship was with Marge after being transported to a foster family. Maggie almost joined the Flanders until she saw Marge once again "and became a Simpson again." At the beginning Maggie seemed to rely on Marge and the likewise but eventually she became fiercely independent as she was able to plan a Great Escape-style breakout from a daycare center to get her pacifier back, she was able to save her father from drowning and rescue Homer from a mad tow truck driver.

Maggie is likely to be the least mature member of the Simpson family, as her voice shows in Bart vs. Thanksgiving and Friends and Family.

Even for a child her age, showed extremely violent mannerisms and a surprising amount of physical strength. She was able to lift up a mallet and bludgeon her father with it and accidentally shot Mr. Burns after he blocked out the sun. Maggie showed to be incredibly strong, able to drag a fully-grown man back to the shore and able lift up a shotgun.

Likely influenced by her brother Bart, Maggie seems to be slightly mischievous, as when Homer was largely immobilized as a result of wearing a body cast, she spun him around like a bottle and took great joy in the endeavor (this happening immediately after Bart himself wrote something on Homer's chest and refused to tell him what).

Biography
When Marge became pregnant with Lisa, she and Homer bought their first home. Seven years later, Homer felt financially secure enough to quit his job at the power plant and take his dream job at Barney's Bowlarama. Soon after, Marge became pregnant with Maggie, and unable to support his new family member, Homer reapplied for his job at the power plant. Homer fell into a deep depression as a result, but when he held Maggie for the first time after she was born he loved her at first sight. He keeps all of Maggie's baby photos in his office to cheer him up at his work place.

For the first 101 episodes of the show and from seasons 1 to 5 (The Boy Who Knew Too Much), Maggie was not a year old yet, and was considered to be in her first eleven months between Simpsons Roasting on an Open Fire and The Boy Who Knew Too Much. Maggie turned a year old in Lady Bouvier's Lover, and has been a year old since that episode.

Despite her above average intelligence, Maggie is impressionable and easily influenced by what she sees around her. She once hit Homer on the head with a mallet, shot a suction dart at his picture and brandished a pencil in imitation of Itchy and Scratchy. Despite her age, Maggie is a formidable sniper and she shot the firearms off a group of mobsters in rapid succession with a rifle. She was behind the attempted murder of Mr. Burns and she fought Gerald during the St. Patrick’s Day riot, participating the republic of Ireland and Northern Ireland. When the family's house was being raided by an angry mob, she was able to smash her baby bottle and use it as a makeshift weapon, and she knocked out Russ Cargill, the head of the EPA with a rock when he was about to shoot Homer with a shotgun.

Maggie is often frightened of her father's attempts to bond with her, even though she does love him. Instead, Maggie shows a much stronger devotion to her mother instead, possibly because Marge is always at home with her while Homer is mostly at work or at Moe's. However, unlike Lisa and Bart, she chose to refer Homer as “Daddy”.

She is keenly aware of her surroundings, and can usually be seen imitating the flow of action around her. Like Bart, Lisa and Homer, she is not fond of spending time with her aunts Patty and Selma. It is also known that she dislikes Baby Gerald very much, despite apparently marrying him in one of the Simpsons Comics.

Appearance
Maggie bears a strong resemblance to Lisa, suggesting that Maggie will look very much like her sister when she gets older. She has yellow skin and blonde, pointed star-like hair that matches the color of her skin, just like Lisa. She wears a light blue onesie with a light blue hair bow, and is almost always sucking on a red pacifier. At night, her onesie and hair bow are white. When she is not sucking on her pacifier, she most often has a straight lip like Marge and Lisa, but sometimes, she has a curved upper lip like Homer.

Holidays of Future Passed shows her quitting her pacifier at around 3 or 4, and at 8 she stopped wearing her bow, although some of her adult appearances show her with a hair bow, and this episode is non-canon. In her future appearances as a teenager and adult, her hair is longer and still in its star like shape, except her first 3 "points" of hair fall forward and the rest are worn back (at least when her head is seen at a third quarter angle like most cartoon characters are seen at). She is usually wearing at least 1 article of blue clothing in these appearances.

Quotes
Although Maggie generally doesn't talk, due to her being a baby, there have been various occasions where Maggie has had words of spoken dialogue. Most of her speaking roles are not to be considered canon, however, with the only known true lines of dialogue being the ones said in Lisa's First Word, Home Sweet Homediddly-Dum-Doodily, Lisa Gets an "A", The Simpsons Movie, Coming to Homerica, Friends and Family, and There Will Be Buds.

And now, if the court will allow me, it's nap time." in the episode "Four Great Women and a Manicure" - A speech made by Maggie in a story told by Marge; Maggie's seventh non-canon word.

All of these quotes were said by Maggie in a gruff, demonic voice, after being possessed by an evil demon known as "Pazuzu". So, technically, it was someone else talking, but it was all being done through Maggie's body, so these all qualify as Maggie's quotes. All together, these count as Maggie's tenth, eleventh, twelfth, thirteenth, fourteenth, fifteenth, and sixteenth non-canonical words.

Violent Mannerism
Maggie can be a violent child, especially for her age. Maggie once had a violent relationship with Homer after watching the violent mannerism acts from Itchy and Scratchy. She had hit him over the head with a mallet and later attempted to stab him with a pencil.

When Mr. Burns planned to cover up the sun, he was shot by Maggie while trying to steal candy from her. The citizens of Springfield deemed it 'an accident'. After figuring this out, it cleared Homer of all charges.

On another occasion, Lisa enlisted Maggie to be her fencing partner. However, when she unknowingly belittled Maggie, Maggie dueled her proficiently and quickly overwhelmed her, even slashing an M into Lisa's shirt, Zorro-style.

She later tried to shoot Mr. Burns again with a shotgun when he lost his memories, but was stopped by Lisa.

When the Mafia was going to kill Marge and Homer, Maggie shot them in the arms with an airgun thus making them unable to shoot.

In The Simpsons Movie, when the mob was attacking the Simpsons, Krusty told his monkey, Mr. Teeny, to take out the baby, referring to Maggie. She then broke her baby bottle making rigid spikes of glass, showing that she was ready to take him on; this scared Teeny who ran into Krusty's arms. Also, later on when Russ Cargill was about to shoot Homer, she dropped a rock on to his head making him pass out. However her violent actions are illustrated as somewhat innocent or at least unintentional, but when she's protecting herself or someone she loves, she uses all her skills - fully aware.

Skills and Abilities
Maggie takes after her sister in many ways. Not only does she greatly resemble Lisa (looking exactly like her in a blue dress in flash-forwards to the future), she also is brilliant and musically inclined like her sister. Maggie can play the saxophone with great ability, despite the fact that she is only a year old.

In "Lisa's Wedding" and "Holidays of Future Passed", it is implied that Maggie is a fantastic singer, again taking after her sister. In the latter episode, Maggie becomes a famous rock star. She is the lead singer in her band, is referred to as "the voice of her generation" on her Christmas card, and plays guitar.

She also has, on numerous, numerous occasions, demonstrated that her agility—both mental and physical—is extremely advanced for her age. Once, Maggie organized the other infants in a daycare into a team to steal a key so they could take back their pacifiers. She figured out communication signals, gathered supplies, used the window-blinds string to pull herself into the ventilation shafts, used a Krusty Doll to lower herself into the room containing the Key (holding bottles to weight herself down and then dropping them so the string would retract), shot a suction-cup line across the room, slid across it with a hanger, and used the key to unlock the locker holding the children's pacifiers. Additionally, Maggie commonly moves along ropes with ease by hand-over-handing her way across them, such as when she tried to escape Homer when he was trying to bond with her by climbing across the clothesline. She usually keeps her intelligence a secret. ("A Streetcar Named Marge")

She also once crawled all over town to her mother's favorite hangout locations trying to track down Marge. Maggie usually has a pretty good comprehension on her surroundings and has at times tried to point out the obvious to adults (mostly Homer) who are oblivious to what is going on. She knows how to read and was seen trying to communicate to Homer using baby blocks, but failed because Homer can't read. Maggie has spelled out E=MC2 with her blocks before and can change her own diapers. She has also used a fire extinguisher to put out burning curtains and has driven Homer's car. Maggie can also skateboard and has already said her first word despite being only a year old.

Although Maggie shows a natural inclination to weapons (see the above section for examples of her ability to defend herself), and aggression, she also has saved members of her family on various occasions, such as when she swam out to sea and saved Homer from drowning or when she saved Bart and Lisa from Groundskeeper Willie in Treehouse of Horror VI.

Maggie also seems to take after her father in bowling, as she has already bowled a perfect game (something it took Homer 39 years to do) at the age of 1.

On some level, Maggie is also influenced by Bart. Like her brother, she is capable of underhanded scheming and rallying others (like babies at the daycare) against a common cause, much like Bart frequently does with his friends and peers.

Recently, Maggie is extremely talented in whistling, so Homer launched her baby-celebrity career for whistling pretty well. This was sidelined by her first tooth emerging.

Homer
Homer has at times forgotten Maggie's existence and Maggie in turn has shown disinterest and even fear towards her father. In fact, she wasn't above targeting him after seeing a cartoon and running away from him when he tried to bond with her or when Marge asked him to hold her. Nevertheless, she recognizes his heart and has shown herself willing to do whatever it takes to save or aid him. When he was on the verge of drowning, Maggie stopped at nothing to rescue him and when he was kidnapped by a crazed tow-trucker, she rode out to liberate him and bring him home (despite earlier wriggling out of his grip to get to Marge). In addition, when Homer was threatened by the mob, she discreetly used a shotgun to disarm and injure them to make sure they couldn't harm him. At one point, when she thought Homer was lost at sea with Bart, she was clearly saddened (like Marge and Lisa), but was overjoyed when she saw him alive and hugged his arm in response. Maggie has also aided her father when he was overpowered by Kearney's son in an attempt to rescue her from being bullied, happily touching his arms afterwards. She has also at one point given her father one of her dolls to take care of in order to cheer him up and while giving him a warm hug, replaced a dream version of Flanders (a reference to her once being one of his foster children) with one of Homer. Most evident of all, Maggie's first word was, "Daddy".

Marge
Maggie has a much closer bond with her mother than any of the family. Most evident when picking between Flanders or the Simpsons, Maggie would have gone to the former until Marge revealed herself changing Maggie's decision instantly. In addition, when Marge was missing for a time (actually on a personal much-needed vacation), a saddened Maggie spent a large amount of time looking for her, even going so far as to search in all of the places she typically goes with her. And whenever she is worried or frightened and Marge is around, she always goes to her for comfort and security. Even then, however, she at times goes against her mother's parenting. Such as refusing to eat certain foods and resisting her insistence on her wearing an itchy sweater.

Bart
Like the other members of her family, Maggie has at times shown aggravation towards her eldest sibling's actions. At one point, she even slapped him repeatedly for choices that he made. And when she was "high off of beer fumes", she picked a fight with Bart and at one point even had him in a stranglehold. Maggie has also (in her own way) tattled on Bart, basically telling their parents that he had a dolphin in his possession. Despite this, Maggie loves her brother very much. So much so, she played with him when he couldn't see Milhouse for a time, pulled several pranks with him, and joyfully square-danced with him at a Dude Ranch. In addition, when he had gone to France for a bit, Maggie gave him a loving hug upon seeing him again and on another occasion played a brief game of Police Detective with him. Even more notably, when Bart was accused of a prank he did not commit, it was she alone who knew her brother was innocent. Though not completely relevant, during a couch gag that saw many Simpsons populate the household, one Maggie incarnation ran straight to an incarnation of Bart for comfort. During two treehouse of horror segments, Maggie held onto Bart for security when climbing down from the treehouse and when falling asleep, laid on him. Maggie has also blown Bart kisses and gleefully took money from him (even though she ended up sucking on it afterwards).

Lisa
After Marge, Maggie seems to be closest to Lisa. The two have similar levels of intelligence and general interests despite their youth and have a strong sisterly bond. Also, next to Marge and Homer, Lisa holds and carries Maggie the most. However, Maggie does express annoyance with Lisa at times and will occasionally act smug towards her, such as when she developed her whistling ability.

Mr. Burns
Although she makes amends with Burns by giving back Bobo, she might have shot him as revenge for hurting all of her family members while trying to get Bobo back.

Ned Flanders
When she, her brother, and sister go to live with the Flanders, she seems fine with it, especially when she said Daddily Doodily after spending time with the Flanders. Even though she did like living with them, we see how much she loves Marge.

Moe
Aside from a non-cannon word of his name in Flaming Moes, she is shown to like Moe as in a few episodes especially in Moe Baby Blues, where he is shown that he likes spending time with her.

Future
In "Future-Drama", Maggie, now 9, went on holidays to Alaska, which was warmer because of global warming. At this age she looks exactly like Lisa does currently.

In "Lisa's Wedding", Maggie is seen as a 16 year old with a punk-like style. It is said that she has an incredible singing voice and, according to Homer, never shuts up (Ironically, whenever she tries to speak, she is always interrupted). She almost performs "Amazing Grace" at the wedding, but Hugh cuts her off to announce the wedding is off.

In "Bart to the Future", she is 31 year old and she has a daughter named Maggie Jr., who looks exactly the same as Maggie. She does not actually appear in the episode, but a deleted scene revealed she became an astronaut.

In "Holidays of Future Passed", Maggie is seen through the 30 year photo montage that she grows up to be a world famous rock star, acting as the lead singer in her band and also playing guitar. In the episode, she is 31 and pregnant and has her baby while traveling to visit her family for Christmas, but she does not have any lines during the last few days of her pregnancy, as prescribed by her doctor, and after she gives birth she is cut off by Grampa when she tries to answer his question of who her baby's father is.

During some future episodes, it's implied that Maggie now has a relationship with her nemesis Gerald Samson. During Milhouse's graduation party, they are kids and are seen holding hands and kissing. In an episode set further into the future, they're seen sharing a drink while staring romantically at each other,. This also hints that Gerald may be the father of Maggie's baby from Holidays of Future Passed.

Treehouse of Horror
In an alternate universe that Homer briefly visited during the "Time and Punishment" segment, Maggie hits Groundskeeper Willie in the back with an axe and then spoke in James Earl Jones' voice: "This is indeed a disturbing universe."

In "Treehouse of Horror IX", during the "Starship Poopers" segment, Maggie loses her legs and arms and grows green tentacles after she got her first tooth (which is a sharp Rigellian tooth). Maggie's pacifier contacts the alien duo, Kang and Kodos. When the duo arrives at the Simpson house, it is later revealed that Kang is Maggie's real father. Maggie then kills Homer.

In“Treehouse of Horror XV", Maggie is eaten by Mr. Burns, but is later rescued by her family.

In the opening of "Treehouse of Horror XXVII", Maggie proceeded to kill Sideshow Bob, the Leprechaun, Kang/Kodos, and (technically) the ghost of Frank Grimes by beheading them while they were distracted with dancing before trying to commit murder on the Simpsons, Maggie included, at a Christmas tree lot.

In Treehouse of Horror XXVIII, Maggie was possessed by Pazuzu.



Behind the Laughter
Matt Groening first conceived the Simpson family in the lobby of James L. Brooks' office. He had been called in to pitch a series of animated shorts, and had intended to present his Life in Hell series. When he realized that animating Life in Hell would require him to rescind publication rights for his life's work, Groening chose to go in another direction. He hurriedly sketched out his version of a dysfunctional family, and named the characters after various members of his own family. Maggie was named after Matt Groening's younger sister Margaret "Maggie" Groening. She often sucked on a pacifier and wore a sleep suit, two traits Groening used for Maggie. Then Maggie made her debut with the rest of the Simpsons clan on April 19, 1987 in the Tracey Ullman short "Good Night". Groening thought that it would be funny to have a baby character that did not talk and never grew up, but assigned any emotions that the scene required. Her comedic hallmarks include her tendency to stumble and land on her face while attempting to walk (though this has been downplayed in later seasons), and a penchant for sucking on her pacifier, the sound of which has become the equivalent of her catchphrase and was originally created by Groening during the Tracey Ullman period, and by Nancy Cartwright during the regular series.

During the show's opening sequence, Maggie is run through a supermarket checkout scanner, which reads that she is worth $847.63 (a reference to the monthly cost of infant-rearing in 1989). In "The Simpsons 138th Episode Spectacular," the scanner instead reads "NRA4EVER," a reference to the running joke that the show's creators are right-wing radicals. In the newer episodes her price has changed to $486.52 (possibly because of the change in the cost of infant-rearing). In the Treehouse of Horror XXIV couch gag, by Guillmero de Toro the scanner reads 666 instead, referring to the number of Satan.

Voice
With few exceptions, Maggie never speaks but is very participatory in the events around her, emoting with subtle gestures and facial expressions. Maggie has spoken in "Good Night", the first short to air, after the family falls asleep. There was another time she had tried to talk in Making Faces short upon the task given by Bart and Lisa. Liz Georges provided the voice of Maggie in Good Night, and by Yeardley Smith in "Babysitting Maggie", "Making Faces", "Football", "House of Cards" and "The Money Jar".

In "Bart vs. Thanksgiving", Bart has a vision of what could happen if he returned home after destroying Lisa's centerpiece. In this vision, Maggie says to him telepathically: "It's your fault I can't talk!"

Maggie's first word spoken in the normal continuity of the series occurred in "Lisa's First Word", when she was voiced by Elizabeth Taylor. Elizabeth Taylor's performance as Maggie was named the thirteenth greatest guest spot in the history of the show by IGN. James Earl Jones, who voiced Maggie in Treehouse of Horror V, was in seventh place. She later had brief dialogue in Treehouse of Horror IX at the end of "Starship Poopers", the third act, voiced by Harry Shearer using Kang's voice. For a few Tracey Ullman Show shorts, Yeardley Smith did many of Maggie's non-sucking noises and occasional speaking parts, but for The Simpsons Movie and since Season 1, her non-sucking noises and occasional speaking parts are done by Nancy Cartwright. Although she has spoken many times, she has only had two canonical speeches that were real within the series. Her first canon speech was in Lisa's First Word, and this word was "Daddy" (as both Bart and Lisa grew up calling Homer his given name); however, only the viewers and not the family heard her say this (at least until the Father's Day clip show). Her second speech was in Coming to Homerica. This time, the family did hear her speak.

According to The Simpsons Movie, the first word the family heard Maggie say was "sequel?", in the ending sequence (unless one counts the Father's Day clip show as being canon). It was stated in the DVD commentary that she was voiced by Nancy Cartwright, who is also the current voice of Maggie in the series.

In Four Great Women and a Manicure, Maggie (voiced by Jodie Foster) rallies her classmates with a stirring speech about injustice and creativity, though this is a non-canon story.

Heroism
Maggie has saved people's lives on a few occasions. Maggie saved Bart and Lisa from Groundskeeper Willie in Treehouse of Horror VI and she saves Homer from being killed by mobsters by shooting them down in Poppa's Got a Brand New Badge. Maggie has even saved her arch-enemy, Gerald from floating into space in a Simpson comic story called Bringing Down Baby. Maggie saved Homer a second time on The Simpsons Movie from Russ Cargill by smashing him on the head with a boulder. Homer also said "What a great little accident you turned out to be", which was referring to the fact that she was conceived at a time that none of her parents intended to, she also saved her father from drowning and from a tow trucker who kept him hostage.

Trivia

 * Maggie has had several rare occasions, where she's had lines of spoken dialogue (see "Maggie's Quotes" above). However, the only time where her dialogue was actually considered canon was in "Lisa's First Word", where she said "Daddy".
 * In this appearance, Maggie was voiced by Elizabeth Taylor, who later guest starred as herself in the same season (Season 4) 12 episodes later in "Krusty Gets Kancelled".
 * Maggie has an oral fixation, meaning that she has the need to have something in her mouth at all times. In her case, she is obsessed with her pacifier and always has the need to suck on it. This is further proven in "Crook and Ladder", where Marge took her pacifier away and she threw a rampage over it. She gave up her pacifier at the age of 4, but even after that, she still had a slight addiction. In "Holidays of Future Passed", she is seen as a grown up, and when she goes into labor, she is given a pacifier to suck on in place of an epidura, which successfully helps her.
 * A running gag affiliated with Maggie is for her to trip over her onesie when she walks.
 * Bart and Lisa generally address Homer by his first name as opposed to "Dad". Maggie is the only child not to follow this trend. This is not only because she can't talk, but also proven when her first word in "Lisa's First Word", was "Daddy".
 * In Every Man's Dream, Maggie made her first and so far, only singing appearance, where Homer had a psychedelic dream where he taught Maggie to talk, and she sang a blip of the song What a Wonderful World. However, this was only a dream.
 * Maggie enjoys playing internet poker.
 * Matt Groening records and makes Maggie's sucking noise on her pacifier himself.
 * Maggie is right-handed, like her father and sister.
 * She is of French, Native American, and Scandinavian descent.
 * In most episodes, when she is not sucking her pacifier, Maggie is shown with a straight lip like Marge and Lisa. Sometimes, she has a curved upper lip like Homer.
 * As of "Frink Gets Testy", Maggie is the only Simpson who hasn't been seen writing out a chalkboard punishment.

Appearances
As one of the five major title characters of the series, Maggie appears in a majority of all the episodes, as well as The Simpsons Movie and the Simpsons games. However, due to her young age and lack of major plot involvement, Maggie is often shown briefly in certain episodes as a background character. There are even certain episodes, where Maggie doesn't appear at all.
