Dr. Lexi T'Perro is the medical doctor aboard the scout ship Tempest. Her wisdom and experience allows her to act in an advisory capacity to the Pathfinder, in addition to evaluating their physical and mental well-being. She conducts her business with due professionalism, although sometimes her caring and compassion goes over it.
Dr. Lexi is 275 years old. She possesses a dry sense of humor, has a sort of a rivalry with Peebee, and a bit of a crush on Drack.
While Pathfinder Ryder is in the outpost Paradise on Elaaden, they can assist Lexi in deducing the stasis pods on the Arks led to chemical inbalances in the bodies of some of the passengers, leading to the violent behavior of the Nexus Exiles who would plague the Heleus Cluster as scavengers and outlaws.
