|“||My Twelve Puns of Christmas are off to a great start. I've only gotta come up with eleven myrrh! Hohohohoho! Make that ten!||”|
— Luan being herself
Luan L. Loud is one of the main characters from the Nickelodeon animated series The Loud House. She is the fourth-oldest of Lincoln Loud's ten sisters, known for her love of comedy. She is a fun-loving teenager who has a tendency to crack a pun whenever she speaks, much to the annoyance of her siblings. Although she is usually one of the kinder Loud siblings, as she always wants to give her siblings a good laugh, she also has a penchant for pulling pranks, especially on April Fool's Day when they become downright fiendish.
Luan's first appearance in a Christmas production was, of course, the show's Christmas episode, "11 Louds a Leapin'". In her subplot of the special, Luan spends Christmas Eve coming up with her annual "Twelve Puns of Christmas", clicking a remote counter with each one. At one point, she also catches her oldest sister, Lori, in the act of trying to open one of their mom's Christmas presents, and encourages her to break her habit. Luan manages to get all the way up to her eleventh Christmas pun by the time Lincoln informs her and the rest of the sisters all about Mr. Grouse being unable to see his family for Christmas. After hearing this, Luan puts her puns on hold and, along with her family and the McBrides, spreads Christmas cheer to their cranky neighbor. After she is shown to have received a magic kit for Christmas, Luan pops up at the very end of the episode to deliver her twelfth pun and wish a Merry Christmas to the viewers, right before she suddenly gets snagged in one of Lana's reindeer traps.
In the online-exclusive Loud House short "12 Days of Christmas", in which the Loud family sings their version of the titular song, Luan sings that her Christmas gift was "four awesome pranks", consisting of using a whoopee cushion on Lori, a joy buzzer on Luna, a squirting flower on Leni, and throwing a pie in Lincoln's face.
