Luna Loud is a main character in The Loud House.
At 16-years-old (15-years-old before Season 5), Luna is the third oldest child of the Loud family, and the middle child of Lincoln's five older sisters. She is a junior at Royal Woods High School with her sisters Leni and Luan.
Her 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 happy, 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.
Before she became interested in rock music, Luna was a shy, gentle and classy girly girl. 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 the violin in "Overnight Success". She sometimes talks with a fake British accent, especially 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 sometimes gets angry and threatening with her fists like in "The Sweet Spot", "Chore and Peace", "It's a Loud, Loud, Loud, Loud, House", "Brawl in the Family" and "Garage Banned". However, most of the time, she uses the vibration sounds of her guitar as a weapon to harm someone when she gets upset.
She will get upset if someone turns off her music, and in some cases, she will get agitated by her siblings. She sometimes gets downhearted when her family isn't with her, or when she upsets her siblings. This was most prominently seen in "House Music".
In "Study Muffin" and "L is for Love", it was revealed that she is bisexual, as she was shown to be romantically interested in both Lincoln's male tutor, Hugh, and a female classmate (and fellow rocker) of hers named Sam Sharp, respectively, with subsequent episodes depicting Luna as having entered a romantic relationship with Sam. In the Live Life Loud! comic "Sam's Pick", it is revealed that all the siblings are aware that Sam is a girl, and Lori considers it sweet that Sam and Luna exchange guitar picks. In the episode "Racing Hearts", Luna and Sam spent a whole day participating in a citywide scavenger hunt together, but to her and Sam's disappointment, they don't have that many things in common, however at the end of the episode they agree that while they don't have much in common, they can still discover new things about each other.
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 eyeshadow.
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 sleeveless shirt with a white skull, torn crew neck, and triangular sleeves, a plaid skirt similar to Luan's (only lavender), a white 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 knee-long purple gown 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 light purple shirt, white earrings, the same square-patterned skirt, white socks with blue stripes worn high and black Mary Jane shoes.
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 that her main guitar is a Logan V-80 Shredder. According to Luna, she got it for her tenth birthday.
Alternate Versions and Alter-egos
However, 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). 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.
In the mini-comic "Deuces Wild!" and its animated adaptation, 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. This later turned out to all be in Lincoln's mind, and in reality the kids were changing Lily's diaper and taking the trash out.
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.
In "Kings of the Con", Luna goes to an Ace Savvy convention cosplaying as the Night Club.
Like Luna, she wears purple, but unlike Luna, it's a dress with a dark purple bodice and light purple skirt and collar. Barbara also doesn't wear any earrings, belt, or boots.
Barbara also plays the guitar like Luna, although she plays an acoustic guitar, not an electric one.
The Rock GodThe Rock God is a version of Luna she imagines in the story the Loud siblings were making up in "A Dark and Story Night".
The Rock God looks exactly like Luna, only much larger, with sharper teeth, and wearing a different outfit. Her outfit consists of a Viking's helmet, a nose ring, a black tank top with a pink lightning bolt, a black necklace, a belt with a skull-shaped buckle, a pink skirt, two pink studded bracelets, and a lightning-shaped earring.
As her name suggests, she is a god, and she sits on a pink cloud. Like Luna, the Rock God likes to play the electric guitar, but unlike Luna, she likes to play the strange hybrid instrument that Luan thought up.
In the story, the Rock God was playing guitar but her guitar had one of the shards of the crystal that the protagonists were searching for. DeLola (Lola's alter ego) made a deal with her to trade the guitar for a different instrument, and so they gave her an instrument that was a hybrid of many instruments they found growing on a tree.
