- Despite being the second-youngest member in the Loud House, she is extremely intelligent and makes a lot of interesting inventions.
- She is very helpful with the family when they need her.
- Although some of her experiments had gone wrong, she is one of the most mature Loud sisters.
- 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.
- 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.
- Despite her intelligence, she can be boring or act like an idiot in some episodes, like "Snow Bored", "Making the Grade", "House of Lies" etc.
- She is sometimes unlikable, such as in "Friend or Faux".
