At 15 years old, Luna is the third-oldest child of the Loud family, and the middle child of Lincoln's five older sisters. Her most annoying habit is speaking in a British, and at one time, a Swedish accent.
Luna's passion for rock music developed when she was just 9 years old. She was still trying to find her own calling at the time. She went to her first concert, and witnessed the lead performer, Mick Swagger, on stage singing, and calling out to her. She took the stage with Mick, and suddenly found out that the world of rock was where she was meant to be and that it was her destiny. Since that day, she has viewed Mick as her hero, because he gave her the inspiration to rock on.
Luna is very wild, caring, and easily the loudest sibling of the entire family. What she likes most is singing, playing musical instruments, and being with her family. Along with Leni, she is one of the most caring and helpful siblings.
After her first concert, she developed an interest in rock music. She is a big fan of several rock groups, and her dream is to become a rockstar. She owns and plays an electric guitar, with which she has proved to be a very good guitarist. Her skills aren't limited to just the guitar though. She also plays the drums, as well as other instruments, as seen throughout the series, like a violin in "Overnight Success". She sometimes talks with a fake British accent when she listens to music; something that her siblings consider to be an annoying habit.
Most of the time, she can be found practicing with her guitar, or listening to rock music. She rarely gets angry, but when it happens she's not above threatening with her fists, and actually using them, like in "The Sweet Spot", "Chore and Peace", "It's a Loud, Loud, Loud, Loud, House", "Brawl in the Family" and "Garage Banned".
She will get upset if someone turns off her music, and in some cases, she will get agitated by her siblings. She gets depressed when her family isn't with her, or when she upsets her siblings. This was most prominently seen in "House Music".
"Luna Loud loves music so much, she speaks in song lyrics! With a boisterous, free-spirited attitude, she is always ready to crank up the volume and rock out. Luna enjoys helping her siblings when they're in need, but she definitely puts the LOUD in Loud House!"
Luna is slightly taller than Luan, but shorter than Leni. She has short brown hair, styled into a pixie cut, freckles on her cheeks, and wears light purple eye shadow.
Her original design showed her with a black shirt, red skirt, and white boots, before her color scheme was transitioned to purple. In her final attire, she wears a purple t-shirt with a skull, torn crew neck and triangular sleeves, a plaid skirt similar to Luan's (only lavender), a light gray belt, and high purple boots. A distinguishing feature of hers is her paperclip earrings. She also wears three black bracelets on each of her wrists and a choker around her neck.
Her nightwear consists of a purple t-shirt with a skull on it, and matching slippers. For swimwear, she wears her signature shirt with matching bikini bottoms. Alternatively, she also wears a purple Hawaiian shirt and shorts.
In "For Bros About to Rock", it is revealed that she had a completely different wardrobe before becoming a rocker. Originally, she had longer hair that went down to her shoulders, extra eyelashes, a girlish light purple shirt, white earrings, the same square-patterned skirt, black Mary Jane shoes, and white socks, with blue stripes worn high.
Her guitar has a purple color scheme, similar to Luna's wardrobe, and it also comes with a purple guitar pic. As seen in "No Guts, No Glori", she can plug it into numerous amps.
Her guitar seems to be a hybrid of a Gibson Firebird, or Epiphone Explorer (with their iconic slanted body), and a Gibson V-Factor (with its iconic inward indent), resulting in a slanted 'X' body.
In Luna's episode of the Listen Out Loud podcast, she mentions her main guitar is a Logan V-80 Shredder.
According to Luna, she got it for her tenth birthday.
Alternate Versions and Alter-egos
In the alternate dimension of the episode "One of the Boys", where Lincoln has brothers, instead of sisters, Luna is a boy named Luke Loud. Like his female counterpart, Luke is an aspiring rocker; however, he is shown to be rude and abrasive toward Lincoln, which completely contradicts how Luna is very caring towards Lincoln, as he uses his head for cleaning the toilet. It is also mentioned that he flushed Bun-Bun down the toilet.
Luke eventually turns out to be a product of Lincoln's imagination as the whole adventure was revealed to be a dream, and Lincoln wakes up from it at the end of the episode. Although in the "dimension" where the Loud children consist of one girl and ten boys, Luke's shown to be very caring and protective towards his sister, Linka (Lincoln's female counterpart).
In the minicomic "Deuces Wild!", Luna interprets the superheroine called Night Club, who is also one of Ace Savvy's sidekicks. She uses an electric guitar, that has a club as the head, with which she can produce powerful shock waves, and a jetpack to fly. 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.
Night Club made another appearance in "Pulp Friction", in the comic Lincoln was writing for the Ace Savvy contest. In that appearance, she used her loud music to knock back the thugs into a hole dug by the Eight of Spades.
