Lincoln Marie Loud is the protagonist from the Nickelodeon animated series The Loud House. He is the 11-year-old middle child of Lynn Loud Sr. and his wife Rita, and also their only male child. Lincoln is an enthusiastic, charismatic, and kind-hearted boy with interests in comic books, manga, video games, fantasy and science fiction stories. He often speaks to the viewers about the chaotic conditions of the household and the insane antics of his ten sisters.
As the main character of The Loud House, Lincoln naturally has a major role in the series' Christmas episode, "11 Louds a Leapin'". The episode's main plot begins when Lincoln goes sledding with his new Fearsome Flyer 8000 sled, which he calls "Big Red", only to accidentally lose it in the back yard of the Loud family's crabby neighbor, Mr. Grouse. With help from his best friend Clyde McBride, Lincoln attempts to retrieve "Big Red", but he is eventually caught and ends up breaking the sled. In doing so, however, he learns that Mr. Grouse is also from a big family, but he has not seen them in five years and cannot afford to travel out to see them for Christmas. Feeling sad for the poor old man, Lincoln tells his sisters all about it, and they all pitch in to give Mr. Grouse a bus ticket so that he can go see his family tomorrow. Mr. Grouse is touched by the Loud family's kindness and apologizes to Lincoln for letting his sled get broken, but Lincoln doesn't mind, saying he's glad that they're friends now. On Christmas morning, Lincoln finds that Mr. Grouse has given him the Fearsome Flyer 1000 sled that he owned when he was a kid, and he goes out to thank the old man for it.
In the online-exclusive Loud House short "12 Days of Christmas", in which the Louds sing their version of the titular song, Lincoln sings that he got six new issues of his favorite comic book, Ace Savvy.
