Sandra Fidalgo is a combatant and camp follower. She had been a regular Latina villager in the Mexican countryside until she made the decision to fight alongside other Carrancista men and women to overthrow the 30-year dictatorship that had ruled Mexico. She may be a simple woman, but she is strong, courageous, talented, and very motivated. She also has a strong feeling of camaraderie, may be slightly nosy, and can get snarky yet outgoing. She sees her fellow fighters as one big family.
