Ryoma Nagare pilots the Getter Dragon, commanding its red Dragon jet within the three-machine Getter Robo G combination system. His origins differ across adaptations. In the original television series, Ryoma is a high school soccer team captain drawn into conflict after witnessing his coach die in a Dinosaur Empire attack, shaping his leadership and sense of duty. Manga interpretations introduce Ryoma as an aggressive martial artist whose exceptional combat skills attract Professor Saotome's attention for Getter Robo pilot recruitment after he defeats multiple assassins. This version exhibits more ruthless traits, including bloodthirstiness against threats to humanity. Following teammate Musashi Tomoe's death during the Dinosaur Empire war, significant grief shadows Ryoma. He initially resists accepting Benkei Kuruma as the new third pilot when the Hundred Demon Empire (Hyakki Empire) emerges. Despite reservations, Ryoma continues leading the team with the upgraded Getter Robo G against this new enemy. Later continuities diverge sharply. In the Armageddon OVA, Ryoma is imprisoned, framed for Professor Saotome's murder. After a nuclear catastrophe, he resurfaces years later piloting a customized Black Getter with a detached, pragmatic combat approach. The New Getter Robo OVA reimagines him as an older, violently efficient veteran pilot confronting Oni forces directly, displaying heightened aggression and combat parkour abilities. Ryoma's combat skills encompass intuitive mecha piloting control of Getter Robo formations and development of combination attacks like the Final Dynamic Special, alongside personal prowess in swordsmanship and bare-handed combat. His leadership persists across timelines, ranging from hot-blooded passion to strategic ruthlessness depending on the continuity. Key relationships include his partnership with Hayato Jin, mentorship under Professor Saotome, and complicated dynamics with replacement pilots like Benkei Kuruma. These connections undergo strain in darker interpretations like Armageddon, where past betrayals and ideological differences fuel team conflict. Character development reflects adaptation-specific themes, with television narratives emphasizing growth through camaraderie and loss, while manga and OVAs delve into psychological trauma, moral ambiguity, and the burdens of prolonged warfare against existential threats.
