Lisa Loud

Lisa Marie Loud is a main character in The Loud House.

Biography
Lisa is the second-youngest child in the Loud family, second youngest of the youngest siblings, and tenth oldest, at 4 years old. She is often seen working on complex experiments, equations, and formulas. Her most annoying habit is her weird studies on others.

Early life
Before the beginning of the series, Lisa, despite her very young age, has already finished up through getting a Ph.D and is also a Nobel Prize-recipient.

Personality
Though the second-youngest of the Louds, Lisa is a child prodigy, so she's the smartest kid in the bunch. Because of this, she often tends to be egocentric and sarcastic with other people. She speaks with a lateral lisp, and usually has a stoic frown, though she does smile from time to time.

She is not as excited as her siblings, although sometimes she becomes in that state when something really good happens, like when she and the other sisters discover about Lincoln's romantic situation in "Heavy Meddle". She states this is because she does not partake in mundane human emotions as stated in "Heavy Meddle". She was also shown to have fallen for Hugh like all of her other sisters, and showed a more perverted side to her, at one point having Hugh show off his six pack under the lie that she was teaching Lola human anatomy with him as an example. She also became somewhat irrational, claiming she would marry Hugh, and have children with him, despite the obvious age difference, and following him around like her other sisters. She also does not believe in superstition, fortune telling, blessings or curses as she is a realist and believes only in science as stated in "Raw Deal" and "Study Muffin". Nonetheless, she likes to be with her siblings and have fun with them, even if she doesn't express it.

In many episodes, she can be seen working on strange experiments. In "Left in the Dark", she creates an Oreo shaped cookie called "Gloweos" with the infused DNA of a jellyfish, and if someone ate it, all of his/her body will glow. One of her favorite hobbies is resolving very difficult math problems. She also likes to study the poop and bathroom habits of her siblings, something they all find gross and annoying.

As seen in "Overnight Success", Lisa not only likes to realize experiments with her siblings, but she also likes to realize them with people outside of her family.

Though easily the most mature of her siblings, Lisa is still a child not above childish plays like food fights. She has her own mischievous side. For the most part her pranks are hidden in unassuming objects; such as acne cream, sunscreen, mouthwash, etc, with results like turning skin blue, mild sunburns, and hot-pepper induced fever, respectively. Lisa is also completely willing to join in the madness caused by her siblings, whether it be disputes over money, the "sweet spot", or just playing along.

Contrasting most of her family, Lisa is very honest and blunt about what is on her mind. Lisa's brutal honesty isn't so much out of a sense of morality, but because she doesn't want wasted brain space by making up a lie. This also makes her incapable of keeping a secret. Like Lincoln she's very individual in contrast to rest of the sisters as seen in "It's a Loud, Loud, Loud, Loud, House".

Lisa, like her polar opposite Leni, is ironically very scatterbrained. She can frequently forget crucial ingredients to her various experiments, which can lead to devastating, though hilarious, outcomes. She also frequently forgets to look up while reading while walking, much to her embarrassment, and tends to misplace her vials, test tubes, and chemicals.

Nick Description
"Lisa Loud is smarter than the rest of her siblings combined. She spends most of her time in her lab setting off mysterious explosions, but she's always willing to help out with homework, or explain the structural flaws in someone's pillow fort. She loves her test subjects siblings!"

Appearance
Lisa has short shaggy brown hair, and wears large glasses to help her see. She wears a green turtleneck sweater, red pants, and brown shoes, all of which droop down to illustrate her stoic demeanor.

Her sleepwear includes a lime green nightshirt with matching pants. Her swimwear consists of blue goggles and a green one-piece with a small purple line in the middle.

Glasses
Lisa's glasses are black-framed with two circular lenses that are a translucent blue color, and only her pupils can be seen through them when she is wearing them.

Levi Loud
In an alternate universe where the sisters are boys, Lisa is a boy named Levi. Like Lisa, Levi is a child prodigy, and speaks really big words, as shown when stopping Lexx and Leif (Lola and Lana) from fighting, and telling them to be quiet, so Leon (Lily) can sleep.

Unlike Lisa however, Levi is shown to be harsh and uncaring towards Lincoln, as shown when the boys mock him after Luke (Luna) uses him to clean the bathroom, and teasing him over wanting a date with Ronnie Anne. He is also harsh towards Dad, as the boys plow him down whenever they see him. He also plays keep-away with the time watch his female counterpart made to send Lincoln home.

In another alternate universe where everyone is the opposite gender, and Lincoln is a girl, Levi is shown to be caring and honest with Lincoln, like Lisa.

Levi eventually ceases to exist, when it is revealed Lincoln's whole adventure was just a dream.

Card Counter
In the minicomic Deuces Wild!, Lisa interprets the superheroine called Card Counter, who is also one of Ace Savvy's sidekicks. She uses a special container to trap creatures like the gas monster. 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.
