Luisa Madrigal (Jessica Darrow) is the middle child in the family. She’s an older sister to Mirabel and the younger sister to Isabela (Diane Guerrero). As a member of the magical Madrigal family, she has the power of superhuman strength and is able to lift heavy objects with ease. She also has a certain degree of increased durability.
In the film, she has a song called “Surface Pressure,” in which Luisa provides an honest glimpse into the stress she feels from her family to always be strong.
