Lincoln is the sixth oldest child, middle child, and the only boy in the Loud family, at the age of 11. His most annoying habit is reading comics, manga and novels in his underwear.
He often speaks to the viewers about how he gets around his often-chaotic household, the insane antics of his ten sisters, and other things he's doing. Along with Lucy, he's the quietest of the 11 Loud siblings.
Lincoln is an enthusiastic and charismatic boy. Although in some occasions he can be selfish, Lincoln is a good-hearted boy, who is always looking for fun, and thinking about the well being of others. As the family nerd, along with Lisa, Lincoln is an avid fancier of comic books, manga, video games, fantasy and science fiction stories, which are typical interests for a boy his age. His favorite comics are Ace Savvy, David's Castle and Comix Jokes. His favorite music band is SMOOCH as seen in "For Bros About to Rock".
He is known to be "the man with a plan", as he is usually elaborating plans with a specific objective, most of them for his own benefits. His plans rarely succeed because of his own selfish and reckless decisions or by his sisters' interference. When he goes too far, he will always find the solution even if that means humiliating himself, as seen in "Making the Case" and in "Sleuth or Consequences".
He tries to make friends with other boys, but they do not care about him as much as Clyde, his only friend. He really feels bad about being an outcast, so he tries to be like the others. He often feels like an outcast even among his own family, as he's the only boy, believing he doesn't have any antics, and his sisters sometimes gang up against him, or treat him differently like in "Brawl in the Family".
Most of the time Lincoln is quiet and relaxed, but sometimes he gets upset when he is annoyed, or when something goes wrong. Also he has proved to be very patient, especially with his sisters. His greatest fear is the family falling apart, as shown in "Butterfly Effect", along with being hated by his sisters, as shown in "Making the Case".
Something that Lincoln has shown is that he is a multi-faceted boy. By living with ten sisters with a different personality each one, he is adapted to them, so he can communicate with any of them and help them with their activities without a problem.
He acts as the "Jack of All Trades" to all of his sisters. He is not as good as his sisters in what they do, but he is competent enough to impress, and help them in what they are doing: such as helping Lucy write her poems, being one step ahead of Luan in her pranks, preventing Lisa's experiment from exploding by adding a chemical, assisting Leni with her fashion designing, and catching Lynn's Football in "Project Loud House". He is also the only one Luna complemented when the Loud House siblings were playing instruments in "House Music".
The episode "Study Muffin" showed he's a responsible student, has such good grades, and that he doesn't really need a tutor, unlike Lynn, Lucy, Lana, and Lola.
"As the middle child and the only boy, Lincoln is often used as a lab rat, or fashion show participant. On the plus side, he gets his own room. Even if it is a converted linen closet. To survive in this house, Lincoln always has to have a plan. With 10 sisters and 1 bathroom, he has to!"
Lincoln is a thin boy with short white hair, and a large tuft of his hair sticks up. He has an overbite with a prominent chipped front tooth, noticeable bags around his eyes, and freckles on his cheeks. He also has chest hair.
Lincoln usually dresses in an orange polo shirt, blue jeans, gray socks with blue and red stripes, and white sports shoes with red stripes. His sleepwear is an orange nightshirt with matching pants, but sometimes he wears an orange t-shirt and his underwear. His swimsuit is a pair of orange trunks. He always reads his comic books in white briefs and socks, but on some occasions, he reads his comic books in his full outfit.
His winter outfit consists of a red coat, with red gloves, a brown hat, and brown boots. He also wears brown ice skates.
Lincoln's white hair is a very unique feature that Lincoln has. He's the only one in the family with this hair color, as his sisters are either a brunette, or a blonde (with the exception of Lucy, whose hair is black (yet, her true hair color may be brunette, as her black hair could be dyed).
Lincoln's second-oldest sister, Leni, is quite fond of his white hair. She says it reminds her of their Pop-Pop, and gets defensive if anybody mocks Lincoln for it, as shown in "Chore and Peace" and "Ties That Bind".
It is uncertain as to why Lincoln's hair is white. Chris Savino has confirmed it's not a result of albinism. One popular theory as to why it's white is because of the effects of stress, since coming from a large family can be very stressful. This, however, is false, as he inherited it from Pop-Pop. Also in "The Whole Picture", it's shown that Lincoln's had white hair since he was a baby, suggesting that he was probably born with white hair.
In the episode "One of the Boys", when Lincoln wishes he had a life with ten brothers, he is sent to an alternate universe of such. When he realizes that having brothers instead of sisters isn't as great as he thought it would be, he tries escaping, and wound up in a dimension where he's a girl named Linka, and is the middle child, and only daughter of the eleven Loud children. Upon realizing that he's in the wrong dimension, Lincoln screams, only to wake up discovering the whole adventure was only a dream.
The dimension with Linka Loud and her ten brothers seems to be more or less exactly the same as the world with Lincoln Loud and his ten sisters--one of the only real differences being that the sexes of the Loud children are reversed. The brothers seem to be just as caring and protective of their sister as the sisters are of their brother. And just like Lincoln, Linka's the only one of the Loud children to have more than four letters in her first name, as all ten of her brothers have four-letter first names.
In the minicomic Deuces Wild!, Lincoln and Clyde imagine themselves as the superhero Ace Savvy, and his sidekick One-Eyed Jack respectively. In this version, Lincoln has great detective skills, and maybe super strength and flight. He also wears a suit similar to Ace Savvy's. In the comic, he and Clyde must battle against a giant gas monster, but it proves to be very difficult to harm, so Ace calls a backup with his entire deck, consisting of different heroines (all of them interpreted by Lincoln's sisters). Together, they fight and defeat the gas monster, and save the day. The troop then prepares to fight against a garbage monster.
He appeared again in "Pulp Friction", when he and One-Eyed Jack were held captive by Wild Card Willy.
Out of all the siblings, Lincoln's the only of one three of the eleven kids to be dating someone--Lori and Lincoln are dating Bobby and Ronnie Anne Santiago, respectively, while Lucy is (presumably) dating Rocky Spokes, the younger brother of Lincoln's friend, Rusty.
His favorite and regular color is orange, which is the same color of the Nickelodeon logo (channel which broadcasts the series).
Lincoln often breaks the fourth wall to explain what he is doing, the progress he's on, and what he has learned in the beginning, middle, and/or end, respectively. When he does it, almost every time he says "But in a family as big as mine..."
Besides the only son in the family, Lincoln's the only one of the Loud kids to not have a four-letter name (his name has seven). However, people sometimes call him "Linc" while his sisters also sometimes call him "Linky".
Lincoln is one of four main characters to have freckles. The other three are Luna, Lynn, and Clyde.
Lincoln, Lily and Lynn are the only siblings who have ever been naked on screen.
It is currently unknown why Lincoln's hair is white. Chris Savino has confirmed that it is not a result of albinism.
However, it's revealed that he got his hair color from his maternal grandfather, who he and his sisters call "Pop-Pop", in "Cover Girls", currently the only physical evidence.
He and Lucy are the only siblings whose hair color is neither blonde nor brunette, being white and black respectively (although it's assumed that Lucy's hair is dyed).
Lincoln and his sister, Lynn, are the only siblings who sleep in socks.
Lincoln and his sister, Lola, are the only siblings with a cowlick.
Lincoln, Luan, Lori, and Lynn are the only siblings who have had more than one set of sleepwear.
Lincoln and Lucy are the quietest of the Loud kids.
Lincoln was named after the street Chris Savino grew up on, which was named E. Lincoln Ave.
In addition, Lincoln being in a family of ten sisters is a reference to the fact that Chris Savino comes from a family of ten children, five of whom were daughters. Savino himself was the ninth child.
In "For Bros About to Rock", his first concert was the first concert that Luna did not ruin. She almost did when they were in line to get tickets, but she made up for it, and gave him an unforgettable time.
However, since he now appears to be secretly dating Ronnie Anne as of "Save the Date", it is possible that he is over his crush on Cristina, or he and Cristina are just friends.
Lincoln's ideal superpower is to have one of each.
Lincoln along with Lucy are the only siblings shown as babies.
Lincoln's stuffed rabbit Bun-Bun is modeled after his original design, when the show was originally about a family of rabbits.
During production, Lincoln was the last one of the children to be named.
A lookalike of him appeared on a billboard in the Disney XD series Star VS. The Forces of Evil.
Despite his small stature and often being seen as the weakest of his siblings, Lincoln's shown to be quite strong. He's strong enough to lift Lisa with one arm in "Changing the Baby", lift Lola with no effort in "Toads and Tiaras", and carry Lynn for a short time in "Linc or Swim".
Lincoln seems to be a good teacher as he used only a manual to teach Leni how to drive, Lana how to dance with a ribbon and Lily how to play chess and video games.
When Lincoln turns his head, the strands in his hair never turn with his head, instead they stay in the same spot.
His Polish name is Hieronim (Jerome), with the nickname "Hirek".
According to episode of Nick Animation Podcast, before Lincoln was decided to be the middle child, there were versions in where Lincoln was part of the older siblings and another where he was part of the younger ones.
Lincoln's Serbian dubber Marijana Živanović also dubs Luan.
So far, Lincoln is the only character to change voice actors. This is due to puberty on the part of his original voice actor.
As shown in "The Whole Picture" during his birthday, the trees had leaves, and there was no snow. That means Lincoln was most likely born during spring, or summer.
Lincoln, along with Leni and Lynn, are the only known siblings that can cook.
According to some information from The Loud House on Instagram:
He has been wondering why his hair is white, and there have been rumors about such.
The best advice he ever received, is to always have a plan.
His favorite foods are pizza and grilled cheese with grape jelly.
His favorite animal is Lana, even though she's a human but acts like an animal.
The best thing about having 10 sisters is that they'll always have your back.
If he could go to any place in the world, he would go to the moon.
His and Ronnie Anne's relationship is complicated; in his words, "I like her as a friend, and yes, she's a girl, but as far as she's concerned, the sloppy joe down my pants says she's not my girlfriend or otherwise."
He can't remember a time where he didn't have Bun-Bun in his life.
SMOOCH is his current favorite band, but he also likes some of Luna's mix-tapes.
He and Clyde met by bumping into each other while dressed as Ace Savvy and One-Eyed Jack, respectively.
