Saburō Katō commands the Black Tiger fighter squadron aboard the space battleship Yamato, executing tactical operations under Captain Susumu Kodai. A strategist in high-stakes combat, he balances tactical acumen with unshakable composure during critical engagements. Following the Yamato’s second campaign, he assumes command of the first Cosmo Tigers squadron, deploying cutting-edge fighters from lunar bases.

When the Comet Empire threatens Earth, Katō returns to active duty alongside Kodai, reaffirming his allegiance to the Yamato’s crew. His dedication culminates in a final, decisive act: evacuating Kodai and Chief Science Officer Sanada from a collapsing battlefield, he triggers explosives to clear their escape path, sacrificing himself to secure their safe return.

The character’s name draws from Tateo Katō, leader of the World War II Hayabusa Fighter Squadron, echoing historical aviation legacy. Katō’s arc centers on unwavering duty and loyalty, his death resonating as both a personal sacrifice and a catalyst for unity in the Yamato’s fight against existential threats.
