Ganigas Gagtos, known as Ganga, hails from the planet Toledolega in the Sava Group. He possesses a muscular, robust build and typically displays a friendly, mediating nature during group conflicts. Ganga battles a lethal planetary endemic that usually kills by age thirty, relying on experimental Toledolega Green Chlorella algae injections; success could provide broader treatment access, though resources remain scarce on his homeworld.

During a mission, Ganga suffers critical electrocution from sabotaged circuitry, causing severe intestinal damage. Fellow applicant Tada performs emergency surgery to remove fried wiring from his intestines, aided by Frol and Glenn. Recovering, Ganga demonstrates loyalty by defending Tada against sabotage accusations. Despite post-surgery weakness, he intervenes in a pivotal vote on Tada's confinement, breaking a tie in Tada's favor to prevent punishment.

His mention of "limited" medical resources post-surgery inadvertently triggers Tada's memory recall about exam conditions. Ganga's actions consistently prioritize group survival, fairness, and cooperation amidst rising tensions.
