Lola is spoiled, sadistic, arrogant, conceited, bratty, sassy, smart-mouthed, and dresses like a princess. Lola's interests include anything girly - this includes fashion shows, makeup, and posing for photo shoots. She is constantly claiming how beautiful she is, and can't look away from a mirror for more than five seconds, which gets on everybody's nerves.
As seen in many episodes (such as "Undie Pressure" and "Sound of Silence"), Lola will assume the role of an antagonist when her siblings anger her or if she doesn't get what she wants. She is skilled at plotting and scheming to get her way. She has the most volatile temper of any of the siblings, and so they, especially Lincoln, are careful not to get on her bad side.
Lola is a tattle-tale, as she can rarely know something without reporting it to somebody else. This is seen in "A Tattler's Tale". In this same episode, Lola is seen to be very manipulative. She threatened her siblings to tell to their parents their secrets, if they don't obey her mandates.
However, in spite of her harsh and self-centered nature, Lola is also compassionate as she loves her siblings. She is always grateful for Lincoln's kindness towards her, and usually appreciates her family's company. At times, she has shown herself to be capable of humility and selflessness when compelled to let go of her own needs, so she isn't completely heartless. In addition, when one of her siblings is in trouble, she has shown genuine concern, and often cooperates with her other siblings to cheer them up. One example is when she helped all her siblings pass a test they didn't study for, even if she failed her own during "No Place Like Homeschool".
"Lola Loud is a pageant powerhouse, whose interests include glitter, photo shoots, and her own beautiful, beautiful face. But underneath all the sugar and spice, lurks a troublemaking mastermind. Lola is the ears and eyes of the Loud House... it's best to stay on her good side!"
Lola has long blonde hair that she wears down, and a tuft of hair on top of her head pointed to the right. She is missing her front teeth, like her twin, Lana. She wears a princess attire; a long pink gown and sash, a white pearl necklace around her neck, long pink gloves, white earrings, pink high heels, and a tiara on her head.
During development, Lola's dress was more frilly, her sash was white, her tiara was more decorative, and she had a ponytail, and her front teeth.
Her swim wear is a swimming dress called a "swim gown", and she uses plastic wrap to protect her outfit when she's swimming, because she doesn't like to be splashed with water. Her nightwear is a pink nightgown, that looks similar to her normal attire, except it doesn't have a sash, or a white pearl necklace attached to her pink gown. She doesn't wear pink gloves, either. It sometimes has short, poofy sleeves on it, as shown in "Room with a Feud". Her snow attire is a pink tundra coat with matching pants, light pink earmuffs, and purple mittens with matching boots.
Lola's tiara is a black wire tiara that she wears in almost every episode she appears in. The only time she doesn't wear it is when she sleeps. So far, the tiara had prominence in the episode "A Tattler's Tale", where she hooked a microphone to it, in order to hear her siblings talk about their secrets.
In an alternate universe where the sisters are boys, Lola is a boy named Lexx. Similar to Lola, Lexx is dressed like a prince, and drives a toy car similar to Lola's pink one. Unlike Lola, who is missing her front teeth, Lexx is missing his canines.
Lexx shares similar personalities with Lola, such as having a rivalry towards his brother Leif (Lana), and threatening to tell on Mom. However, he is hostile toward Lincoln, laughing at him after Luke (Luna) uses him to clean the toilet, when Leon bites his thumb when he gets a "boo-boo", and stealing two of his shirts, because his were dirty. He also plays keep-away with the time watch Lincoln needed to get back home. He also calls Lincoln a loser, which is an insult neither Lola, nor any of his other sisters have ever called him.
In another alternate universe, Lexx is shown to be caring towards Lincoln, who is a girl named Linka here, similar to Lola.
Lexx eventually ceases to exist when it was revealed the entire adventure was just a dream.
Queen of Diamonds
In the minicomic Deuces Wild! and its animated adaptation, Lola interprets the superheroine called Queen of Diamonds, who is also one of Ace Savvy's sidekicks. Her power is using her diamond cape to shine bright light on her target and blind them. 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.
She appears in Lincoln and Clyde's comic in "Pulp Friction", where she throws her diamond tiara to stop some thugs.
According to The Loud House Instagram, when Lola grows up, she wants to be a queen or empress.
She says that she would like to become whichever has the "sparkliest crown".
Her favorite food is princess pie.
Lola and Lucy aren't close to each other, like how their roommates Lynn and Lana are.
The main reason could be because even though it's revealed by Lincoln in "Room with a Feud", that Lola and Lucy both have a flare for the dramatic, Lucy is gothic, gloomy, spooky, dark, moody, depressed, cynical, deadpan, mysterious, and dislikes the color pink, whereas Lola is girly, spoiled, arrogant, conceited, bratty, sassy, smart-mouthed, prim, perfect, and dislikes ghosts, thus making them both too different to be close to each other.
Lola is the only Loud sibling to refer to Lynn Sr. as "Daddy" and Rita as "Mommy".
According to the episode "The Mad Scientist", Lola does not know what an institute is.
It is implied that Lola is bad at her education, such as in "Rita Her Rights" where she says her teacher takes breaks a lot and screams in an empty locker. Also, in "Ruthless People", Rita says Lynn Sr. has to attend 20 parent-teacher conferences including Lola's, meaning her parent-teacher conferences go badly.
Lola lost a beauty pageant for the first time in "Gown and Out".
