Lisa Loud

Lisa Loud is one of the main characters in The Loud House. She is the second-youngest child of the Loud family, and the second-youngest of Lincoln's five younger sisters. She is often seen working on complex experiments, equations, and formulas. Lisa Loud herself attends kindergarten at Royal Woods Elementary School and later first grade as of Season 5, despite her very young age, is a Junior Nobel Prize recipient. Though she is still in first grade (kindergarten in the first four seasons), she is exceedingly smarter than the other kids her age and is shown to be capable of moving up at least six grades.

Why She Is A Smart Scientist

 * 1) As mentioned above, despite being the second-youngest member in the Loud House, she is extremely intelligent and creates a lot of interesting inventions.
 * 2) She is very helpful with the rest of the Loud family when they need her.
 * 3) Although some of her experiments had gone wrong, she is one of the most mature Loud sisters.
 * 4) Lisa also likes to realize experiments with her siblings. Not only her siblings, but she also likes to realize them with people outside of her family.
 * 5) She also has a fun side too, as seen in "Party Down" where she goes hype over chocolate, although it might be taken too far at one point.
 * 6) She has a cute design as well.
 * 7) Her voice acting by Lara Mill Miller is great.
 * 8) She cares about her family and friends.

 * 2) Lexi Janicek was not a great voice actress for her in live-action appearances.
 * 3) She can be a bit of a know-it-all at times.
