At 6 years old, Lola is the third-youngest child of the Loud family, and the middle child of Lincoln's five younger sisters. She is also Lana's younger twin sister. Her most annoying habit is constantly looking in the mirror to appreciate her looks.
Lola is spoiled, 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 narcissistic, as she is constantly claiming how beautiful she is, and can't look away from a mirror for more than five seconds, as seen in "Undie Pressure".
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 heartless.
"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.
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!, 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.
