A karate master and head of the shinshinkai-kan (a karate style which seems to be inspired by the real-life style of kyokushin karate). One of the few people in the world able to stand toe-to-toe with Ujiro. He whips his students into shape by fighting them regularly, and practices all of his karate techniques at least one thousand times daily. A very devoted karate practitioner, and a mentor of Baki's. Also, the instructor of Katou and father of Katsumi. He fought Yujiro, who gouged his eye out and almost killed him. However, Doppo was revived by Kureha. He eventually fights the escaped American convict Dorian in the 'Search of Our Strongest Hero' manga series. Dorian manages to cut off Doppo's hand with a strange wire-cutting technique in which he uses a wire blade projected from a lighter. Doppo later avenges this loss when he, Katsumi, and Retsu track Dorian down. Shortly after this however, Dorian escapes from the hospital and uses an explosive that is implanted into his hand to blow off part of Doppo's face. Doppo later returns to have a battle with Mohammad Ali Jr. In the Maximum Tournament, he fights Richard Phyllis in round 1, Amanai Ryu in Round 2 before facing another master Gouki Shibukawa in round 3 which he loses after a brutal match. After that loss, he decides to close down his dojo and start his training all over again. He is apparently based on the real-life creator of Kyokushin karate, Sosai Masutatsu Oyama. They are very similar to each other: they both created forms of karate, they both gained notoriety by killing deadly animals, and they have similar appearances. « less
