Fernando "Nando" Parrado – 22 | Male Role: The driving force behind the rescue. After waking from a three-day coma to find his mother dead and sister dying, he became single-mindedly obsessed with walking out of the mountains. He and Canessa completed the grueling 10-day trek to find help.

Roberto Canessa – 19 | Male Role: The group’s medical lifeline and co-expeditionary. As a first-year medical student, he assumed the role of doctor, treating horrific injuries and setting bones. He initially resisted the final trek out of caution but ultimately walked alongside Parrado to save the group.

Antonio "Tintín" Vizintín – 19 | Male Role: The powerhouse muscle. Chosen as the third expeditionary due to his sheer physical strength, he helped carry the heavy gear up the initial mountain peak. When they realized food supplies were too low for three men, he selflessly gave his rations to Parrado and Canessa and slid all the way back down to the fuselage alone.

Adolfo "Fito" Strauch – 24 | Male Role: The brilliant innovator. Along with his cousins Eduardo and Daniel, Fito became a de facto leader after the team captain died. He invented a solar water-melting device from metal seat backs, preventing the survivors from dying of dehydration, and designed sunglasses from plane parts to fight snow blindness.

Daniel Fernández – 26 | Male Role: The logistics anchor. As one of the older, calmer cousins, Daniel managed the division of labor, calculated the tiny daily food rations, and mediated arguments, maintaining mental discipline inside the crowded, freezing fuselage.

Gustavo Zerbino – 19 | Male Role: The medical assistant and memory-keeper. He worked tirelessly alongside Canessa tending to the wounded. Crucially, Zerbino collected and preserved the personal effects, letters, and valuables of those who died, promising to return them to their families—a promise he fulfilled.

Carlos "Carlitos" Páez Rodríguez – 18 | Male Role: The seamstress and spirit-booster. The youngest survivor, Carlitos used his mother's sewing kit found in the luggage to stitch together the massive insulation sleeping bag the expeditionaries needed to survive the freezing nights on their trek.

Numa Turcatti – 24 | Male Role: The spiritual heart of the group. Though not a member of the rugby team, Numa was universally loved for his exceptional bravery and selflessness, volunteering for the most dangerous scouting missions. His tragic death from a leg infection on December 11 (day 60) devastated the camp and served as the final catalyst for Parrado and Canessa to leave on their rescue mission.

Marcelo Pérez – 25 | Male Role: The initial captain. As the official rugby team captain, he organized the initial survival efforts, rationing the tiny amounts of food they had and keeping hope alive that they would be rescued. He tragically died on day 16 when an avalanche smothered the fuselage.

Liliana Navarro de Methol – 34 | Female Role: The maternal figure. The last surviving woman on the mountain, Liliana provided invaluable emotional warmth and maternal care to the injured, terrified young men. Her nursing instincts kept morale high until she was tragically killed in the October 29 avalanche.
