In Disney's Encanto, what is the name of Mirabel's sister with superhuman strength?

In Disney's Encanto, Mirabel's sister with superhuman strength is Luisa Madrigal.

Luisa is one of the Madrigal family's gifted members. Her magical ability allows her to lift extraordinarily heavy objects, including donkeys, bridges, and buildings. Because the community depends on her power, she feels pressure to remain strong and dependable at all times, even when she is exhausted or frightened.

Her emotional conflict is explored in the song “Surface Pressure,” performed by Jessica Darrow. Luisa is the middle daughter of Julieta and Agustín, and she is older than Mirabel and younger than Isabela. She is sometimes confused with Isabela, whose gift involves growing flowers, or Dolores, whose gift is exceptional hearing. The film uses Luisa's magical strength to examine the burden of family expectations.
