Mamoru Uda

Mamoru Uda stands out as one of the most humanizing supporting characters in Parasyte. Unlike typical parasite hosts, his brain remained untouched when the parasite 'Joe' took over his jaw and neck, allowing him to retain full consciousness in a rare symbiotic coexistence. Once driven to the brink of suicide during a personal crisis, Uda unexpectedly gained extraordinary physical capabilities through this fateful encounter. Known for his warm disposition and tendency to cry openly, he brings heartfelt compassion to every interaction—especially toward Shinichi's harrowing experiences. As a key ally, Uda delivers critical combat support at pivotal moments, making him an indispensable and deeply relatable figure throughout the series.
