Doppo Orochi, a 10th dan karate grandmaster, founded the Shinshinkai Karate School. He is married to Natsue Orochi and serves as the adoptive father of Katsumi Orochi, whom he took in and trained after witnessing Katsumi's biological father die in a circus lion incident. Doppo bears formidable titles: "God of War," "Man Eater Orochi," "Tiger Slayer," and "Fist Saint," the latter earned for killing a Siberian tiger in his youth—an act he later deemed reckless. Physically imposing at 178 cm tall and 110 kg, Doppo is bald and heavily muscled. He wears an eyepatch over his lost right eye, a result of scars inflicted by Yujiro Hanma. Additional facial scars came from blast injuries sustained during his battle with the death-row convict Dorian, who also severed his hand; the hand was later reattached. He typically wears a karate gi marked "Shinshinkai" on the right and "Director" on the collar. His personality blends pride, tactical brilliance, and occasional ruthlessness with deep loyalty to his family. He comforts his wife before dangerous fights and fiercely protects Katsumi. Doppo holds an intense, near-delusional belief in karate as the supreme martial art, a conviction that can blind him to unconventional threats. His exceptional tactical mind allows him to meticulously analyze opponents' stances, techniques, and weaknesses beforehand, devising multiple strategies. This analytical skill even enabled him to predict movements while hallucinating under Dorian's hypnosis. Doppo possesses superhuman physical traits, extraordinary pain tolerance—fighting through eye gouging, hand severing, and being bisected by Miyamoto Musashi—and mastery of pressure points and specialized techniques: - **Sangan**: Enhances peripheral vision via eye tendon control. - **Kokoken**: Strikes the Endou point to blind or stun. - **Roppa Gaeshi**: Targets Tendo points to disrupt skull sutures. - **Bodhisattva Fist**: Suppresses bloodlust and mental presence, evading extrasensory detection. - **Mawashi Uke**: Redirects attacks. He also exhibits limited instinctive reactions, body control for statistical amplification, and enhanced senses, detecting concealed weapons by sensing bloodlust or smelling materials like metal or ink. Significant battles define his combat history: - **Early Feats**: Fought Yujiro Hanma, landing blows that dented Yujiro's torso and briefly stunned him, losing his eye. - **Maximum Tournament**: Defeated Richard Filth and Yuu Amanai before losing to Gouki Shibukawa in the quarter-finals. Requesting a warrior's death, he was spared, fostering mutual respect. - **Dorian Confrontation**: Continued fighting after Dorian severed his hand with a concealed wire, ultimately defeating the convict. - **Musashi Miyamoto**: Survived being vertically sliced. Post-tournament, Doppo rebuilt his strength from scratch, eventually surpassing his prior capabilities and earning recognition from fighters like Retsu Kaioh. His legacy includes mentoring students like Kiyosumi Katou and Atsushi Suedou, though his rigid adherence to karate's supremacy remains a noted weakness, leaving him vulnerable to non-traditional or deceptive combat styles.
