|For her episode of Listen Out Loud, see Luan Loud (Listen Out Loud).|
At 15-years-old (14-years-old before Season 5), Luan is the fourth oldest child of the Loud family, and the second-youngest of Lincoln's five older sisters. Luan is a sophomore (a freshman in Seasons 1-4) at Royal Woods High School and attends school with her siblings Leni and Luna. Her habits include telling jokes and puns (which many of the other characters don't like), pulling pranks, party clowning, and video production.
In "Time Trap!", Luan and her siblings altered history, causing their parents to decide not to have any kids in the future. As a result, Luan got deleted out of existence, although she returned when Lisa and Lily prevented this timeline alteration.
Luan has been into comedy since her infancy. When was a baby, she entertained her family with sock puppets. When she was a one-year-old, she would go out on her tricycle and pie the mailman in the face. Around that time, she also became a big sister when Lynn was born.
Around ages three and four, she played patty cake with Lynn. Luan also used her baby brother Lincoln as a ventriloquist dummy and cheered him up along with her other sisters whenever he got upset. At age six, Luan was the middle child when Lucy was born. At age seven, she went on a mechanical-pony with four-year-old Lincoln and one-year-old Lucy. She also owned another ventriloquist dummy (before Mr. Coconuts) named Colonel Crackers.
Luan began doing stand-up comedy when she was eight years old where she performed for the Loud family pets' birthdays. She performed out in public for the first time at the Royal Woods Bowling Alley but the audience did not enjoy her performance and heckled her with curly fries. At some point Luan originally used fresh whip cream for her pranks but stopped around when the twins were born so she could use spoiled products to attract animals.
Around ages ten and eleven, she owned a unicycle which she used for a juggling act involving apples and bowling pins. Luan later enrolled in a clowning academy to get better at jokes and started her business, Funny Business Inc.. Like her older sisters, Luan attended Royal Woods Middle School and was served undesirable food at lunch from Chef Pat due a grudge held against her mother, Rita.
Luan is a very goofy and fun-loving girl with an enthusiasm for comedy and making puns. Her goal is to make the world laugh along with her, though some of her material still needs work. She loves pulling pranks on her siblings and frequently makes puns for every situation, causing her to get on everyone's nerves. While Luan laughs at others' humiliations and often comes off as a nuisance to others, she does it with good intentions and does not mean to harm anyone as she just wants to make people laugh. Despite Luan's occasional ruthlessness she is mostly friendly towards her siblings, especially to Leni and Luna.
She has a taste for everything that is related to comedy - this includes comedy movies and TV series, clowns, pranks, stand-up comedy, and funny internet videos. Her most common pranking methods are dodging people in the face with pies and placing a whoopie cushion on others' seats. She also likes to record people experiencing funny situations with her video camera, but Luan is a strict ethicist so when she does this, she asks permission to the person she recorded to allow her to upload the video to the Internet. Unlike Lincoln, Luan already knows that she cannot upload videos without her subject's permission.
Though Luan is typically one of the kinder siblings, she utterly loses control when it comes to pranks, particularly on April Fools' Day. When April Fools' Day comes, Luan becomes ruthless and crazier than ever to the point of being downright evil and psychotic. During this day, her pranks can be even more dangerous than usual like when she placed pitfalls in every corner of the house, transforming the entire house into a lethal comedy trap. This is the only time of the year where Luan is thoughtless and cruel to her entire family. In "Fool's Paradise," after her family made Luan taste her own medicine, she promised the next April Fools will be even worse than before. In "Fool Me Twice," the Loud family hires a stunt double family to endure the horrible April Fools' Day with Luan. However, Luan hires the stunt family to successfully ridicule the original family. When Luan arrived home, however, she sees her family, in shame, preparing to move. She remorsefully regrets her actions and promises to her family that she'd never prank them again. The family staged this as an April Fools joke, and Luan, in relief, commended to her family she's glad that they're finally getting the hang of April Fools, but suggests to her family to stop the moving truck. In the end, Lincoln tells Luan that the moving truck has mostly empty boxes, but the boxes with stuff in them have all of her stuff, which makes Luan chase after the truck.
She always has a positive and cheerful attitude. She is very optimistic, as she likes to support her siblings, and especially make them laugh and feel better. This becomes a plot point of "Head Poet's Anxiety," where Luan acts as Lucy's inspiration for pursuing a life in the showbiz industry. However, this episode also shows a jealous side to her, as Luan holds a grudge against Lucy for surpassing her dream of becoming the youngest performer at the Royal Woods Theater; although, she eventually drops her selfishness and encourages Lucy to do her performance. On some occasions she can get angry when drama unbreaks in her family; like when she fought against her siblings to obtain a seat in Vanzilla, when she and her siblings destroyed the whole house looking for money, or when Luan and her siblings argued. No matter how bad any problem is, she'll find the funnier side of the matter.
Despite her default cheerfulness, Luan has expressed emotions of sadness, vulnerability, and insecurity a few times in the series and has implied herself to be in desperate need of affection. She seems to be sensitive to criticism, as seen in "No Laughing Matter" when she becomes timid as a result of her siblings expressing blunt annoyance to her comedy routine and walks to her room on the verge of tears. However, she does not wear her emotions on her sleeves in this situation, as she closes her eyes rather than full-stop crying out loud, to avoid giving her siblings the impression of immorality, also showing that she lacks courage. Likewise, Luan gets jealous of Lucy surpassing her lifelong dream of becoming the youngest performer of Royal Woods Theater and becomes obsessively possessive of her upon discovery of the news. However, instead of trying to sabotage her moment in the spotlight, Luan eventually drops her jealousy and gets Lucy to perform at the theater, since Luan herself was the inspiration for Lucy's poem.
She is also quite neurotic and socially awkward whenever faced with the world's consequences, yet remains obedient to reality. For instance, the entire plot of "Stage Plight" revolves around Luan becoming increasingly anxious over having to kiss her crush during the play recital of Romeo and Juliet.
Luan is rather immature, as she has a childlike fondness for pranking people and laughing at their misfortunes. Like her sister Leni, she is generally portrayed as naive, simpleminded, idealistic, ignorant, eccentric, and impulsive. She is prone to bothering others with her sense of humor while they're minding their own business, like in "Garage Banned" where she comes back into Lori's room after the latter demands privacy, and harasses Lori by mocking Bobby on the phone using Mr. Coconuts, making the puppet kiss her; this also sets up the plot. Luan's immaturity is also exhibited through her possession of toys of the novelty variety, which are a frequent use in her comedy routine, most especially her dummy, Mr. Coconuts. She occasionally jokes around in inappropriate situations, like making a prison joke while her mother is in jail, and planning to tell Rita jokes about how old she is at her birthday party.
Despite her immaturity and passion for comedy, Luan has on numerous occasions shown herself capable of acting serious and responsible if the situation warrants. This reaches its epitome in "No Laughing Matter," where she abandons her comedy routine and behaves like a civilized human being following backlash from her siblings. Additionally, she interned at the mayor's office in "Future Tense" and helped solved Royal Woods' parking crisis, although this was done on behalf of her parents. She is shown to be mature enough to babysit along with her three older siblings.
Luan is very intelligent, as she is able to outwit her family with her pranks; in "Fool Me Twice", she hires the stunt family to ridicule the stunt double family with success; she also intimidates her parents to the point of them being too scared to punish her. Luan enrolled in a clowning academy when she was younger and graduated, turning her into the clever prankster she is today. Despite being skilled in the art of comedy, Luan's scholarship has had limited exploration in the series; however, she knows that 3.14159 equals Pi, but she had trouble interpreting another one of Lisa's math problems when she dropped her comedy routine.
Luan has prominent buck teeth, which sport silver braces on her upper and lower teeth, and light brown hair worn up in a large ponytail with a small swirl at the end by a yellow scrunchie (presumably the hairtie), with two long protruding hairs sticking out from the center of her forehead. In The Loud House Movie, her ponytail is slightly different, and it appears to be worn slightly higher as well. Her movie design also depicts her eyes as closer to her nose (albeit only when she is viewed from the side).
She dresses in a white sleeveless shirt, a yellow skirt with a checkerboard pattern, yellow socks with a line pattern that are worn all the way up, and brown shoes. She also wears three pink flowers, one on her shirt, and one on each shoe, that serve as gag squirt-flowers. Her prototype design had a gag flower on her skirt, but none on her shoes. She also didn't have any braces.
Her swimsuit is a yellow one piece with one of her gag-squirt flowers. Her nightwear is just a yellow nightgown or a yellow and white nightshirt with matching pants and white bunny slippers. Sometimes, she also wears a yellow bathrobe.
She has been wearing her braces from her younger age. Back then, she wore a sleeveless yellow dress with a square pattern, a black belt, white socks, and brown ballerina flats. She also wore a pink helmet with dark pink polka dots on it whenever riding her unicycle.
When Luan was even younger, she wore a sleeveless yellow dress with a checkerboard pattern and white undershirt underneath, light pink socks that were worn all the way up, and black Mary Jane shoes. She also wore pigtails in two yellow scrunchies. The two protruding hairs sticking out from the center of her forehead were also backward and more curly. Her eyebrows were also less curved and rather pointy, while her nose was less pointy and more curved.
Luan's live-action counterpart is the same, except that she wears a white long-sleeved blouse as opposed to a white sleeveless shirt and black boots. Since the live-action counterpart belongs to a Christmas-themed media, Luan may be seen wearing an attached pair of variable reindeer antlers. The only live-action appearance of Luan not wearing antlers is the photo of the cast reveal photoshoot.
Luan's flower is a gag squirt flower that she wears in every episode she appears in. Luan owns three of these flowers, one is on her shirt, and the other two are on her shoes. Although only shown twice, these gag flowers are filled with water. Even if she fills these flowers with water, she likes to wear them for decoration.
Luan's gag glasses are black glasses, with eyebrows, and a pink nose and mustache at the end of them, which are a reference to Groucho Marx of The Marx Brothers. They seem to double as reading glasses.
Alternate Versions and Alter-egos
In an alternate universe where the sisters are brothers, Luan is a boy named Lane. Like Luan, Lane is a comedian who tells jokes to lighten the situation. However, he acts disrespectful toward Lincoln, mocking him when Luke (Luna) uses him to clean the toilet, when Leon (Lily) bites his thumb instead of kissing it, and when they tease him about Ronnie Anne. He also plays keep-away with Lincoln's time watch to stop him from going back to his own dimension. Additionally, Lane is also disrespectful to Lincoln as he had pulled his trousers up and said to "Use them as a shirt."
In another alternate dimension where he is the brother to a female version of Lincoln named Linka, he is shown to be deeply caring for her.
Lane eventually turns out to be a product of Lincoln's imagination as it was revealed the entire adventure was a dream.
This version of Luan has a female version of her dummy Mr. Coconuts, named Mrs. Coconuts.
In the mini-comic "Deuces Wild!," Luan interprets the superheroine called "The Joker," who is also one of Ace Savvy's sidekicks. Her powers are not shown, as she's only seen mocking the gas monster. In the comic, she is summoned by Savvy (played by Lincoln) alongside the rest of Savvy's deck (played by the rest of her sisters) to help him and One-Eyed Jack (played by Clyde) to defeat the gas monster. After they defeat it in which is sucked up into the trash can, they prepared to fight against a garbage monster. (In reality, all Luan and her siblings were doing was changing Lily's diaper and taking out the garbage).
The Joker also made her first episode appearance in "Pulp Friction." In her appearance there, she used a jack-in-the-box-like gadget to defeat Wild Card Willy by having it spring under his feet, which threw him across the warehouse they were in.
In "Kings of the Con", Luan attends an Ace Savvy convention cosplaying as the Joker.
The Joker has her hair in pigtails, and has one red scrunchie and one yellow. She wears a yellow mask with a red diamond-shape over one eye and a black one over the other, a yellow and black jester's shirt, one yellow boot, and one black boot. Her name comes from the Joker playing card, and the fact that she tells jokes.
In "White Hare," where Lincoln imagined how difficult it is to live with 15 extra sisters, Luan is a rabbit named Bebe. Like Luan, Bebe is a comedian who tells jokes to lighten the situation and, like the human counterparts, none of her siblings find her funny.
