|Not to be confused with the father of the Loud children.|
Lynn L. Loud, Jr. is a main character in The Loud House.
At 13 years old, Lynn is the fifth-oldest child of the Loud family, and the youngest of Lincoln's five older sisters. She is named after her father. Lynn attends Royal Woods Middle School. She has a habit of turning everything into a competition.
In "Middle Men", Lynn confessed that she had a miserable, if not depressing, time in her first year of middle school, describing it as a "real horror story". Back then, she was more soft-hearted, tender and sensitive, but she was humiliated and picked on multiple times by her peers in school. Because of this, she acted more aggressive and tough against others. Although it prevented her from ever being bullied again, it has just caused her to become more violent and forceful over the years. Nonetheless, she is still caring and she just didn't want her brother or Clyde to suffer like she did.
Lynn is athletic and competitive. She loves to play sports and enjoys roughhousing with her siblings.
She enjoys playing every existing sport, including football, soccer, hockey, basketball, and baseball. She is also skilled in various forms of martial arts, such as kickboxing, Mexican wrestling (or Lucha libre), and parkour. As seen in "Undie Pressure", Lynn tends to turn everything into a competition - her siblings consider this to be her most annoying habit. She is also shown to be very competitive, and strives to be "number one" in every game she plays, even when winning isn't involved.
Despite her tomboyish attitude, she shows a more feminine side on rare occasions, and takes part in her sisters' girly activities. She shows no shame in using puppy eyes to get what she wants, such as bunking in Lincoln's room in "Space Invader". In "Heavy Meddle", she gets as excited as her sisters after finding out about Lincoln's romantic situation. In "Back in Black", she helps with Lucy's makeover as the rest of Lucy's sisters do. In "L is for Love", she happily sighs after Lori reads a love letter.
Lynn is very superstitious and makes up absurd assumptions, such as in "Sleuth or Consequences"; where she tells Lincoln that she never "bombs the toilet" before a big game of roller derby because it's bad luck. This is also prominent in "Intern for the Worse", where she doesn't allow her teammate, Margo, to use the bathroom, because of the same belief. In "Cover Girls", she tells Lincoln to cover for her while she is at the batting cage to hit baseballs to avoid spring cleaning, and she said if she didn't hit the first ball, she'll have bad luck all throughout the baseball season. This is shown again in "No Such Luck", where she is shown to perform good luck rituals, and unfairly believes Lincoln is bad luck when he comes to her game and she loses, ruining her winning streak.
Lynn is also very immature, as shown in "Cereal Offender" when she rides on carts in the grocery store and wrecks several aisles. Another example of her immaturity is shown in "A Tale of Two Tables", where she participated in the food fight with her siblings. Another part of this immaturity is her poor sportsmanship. When she loses, she starts throwing tantrums, and if she wins, she starts gloating at others, until someone makes her realize she's hurting their feelings.
Lynn isn't exactly above employing underhanded methods in order to win. In "Space Invader", she complements Lincoln's wrestling ambush upon entering his room, even if it is considered cheating. Another instance occurs in "Lynner Takes All", when she tricks Lincoln into giving the wrong answer during a trivia game.
Although in "Net Gains", she may have finally learned true sportsmanship when she was put in a bad basketball team called Turkey Jerkies and since she was so blinded by winning the championship, that she forgot the real reason why they play basketball: to have fun. She even accepted her and the teams' loss with pride at the end.
In "Sitting Bull", it is revealed that her aggressive attitude causing her to abuse the kids that she babysat, which causes their parents to fire her older sisters. After she was placed to babysit the Fox quintuplets, her methods proved effective when used on rough children, and she also give her sisters their customers back.
Since it was shown in "Middle Men" that she has grown to become more assertive and competitive because of her fear and depression in the 6th grade, it is possible that she is just really insecure about herself and hides it by acting aggressively. If she didn't, she would be bullied forever. However, hints of insecurity can be seen in her overreliance on good luck rituals and amulets, which suggests a Lynn has lack of faith on her abilities in sports.
In "Hero Today, Gone Tomorrow", she is revealed as she cannot handle her pride and jealousy. If she sees someone getting more attention than her, she gets extremely upset and jealous. At the end, she finally realized that her behavior causing her to lose her friend and started to become supportive rather than jealous.
Lynn has thick brown hair pulled back into a short high ponytail that is smaller than Luan's. She wears a red and white jersey with a red "1" on it (which is revealed to be her roller derby shirt as shown in "Lock 'n' Loud"), red-and-white track shorts, and black cleats with striped white knee-high socks. She is slightly taller than Lincoln and has freckles on her cheeks. Despite her age, her short appearance makes it seem like she's a preteen, not a teenager. Like most of her siblings, she has purple-gray eyelids.
Her original night-time attire consists of a white tank top, red shorts, and ankle high socks. In a few instances, she is shown wearing a nightshirt that looks like her regular jersey, with socks instead of her usual sleepwear. Beginning in the start of season 3, her usual night attire consists off a white and red sports shirt with a 5 on it and red shorts, although in a few instances post season 2, she is instead shown with her original night attire. Her swimwear is a red-and-white surf shirt with matching swim trunks.
Alternate Versions and Alter-egos
Boy Lynn Loud
In "One of the Boys", a male version of Lynn appears in the alternate universe where Lincoln has brothers instead of sisters. Unlike the others, he has the same name as his female version and is pretty much the same as Girl Lynn. Here, he shares the same room with Lars and Lincoln. The only thing different about him is the hairstyle.
However, Boy Lynn is shown to be even more rough towards Lincoln than Girl Lynn, punching him for little to no reason, and playing keep-away with the time watch Lincoln used to travel to the alternate universe. In another alternate universe where Lincoln is female, he is shown to be caring and protective, like the female Lynn.
Boy Lynn eventually turns out to be a product of Lincoln's imagination as the entire adventure was a dream, though Lincoln states Girl Lynn somewhat acts the same as Boy Lynn does.
In the minicomic Deuces Wild!, Lynn interprets the superheroine called Strong Suit, who is also one of Ace Savvy's sidekicks. She has super strength. 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, they prepared to fight against a garbage monster.
Bailey is one of the rabbit sisters, and a rabbit version of Lynn who is sporty just like Lynn, along with Bertha.
