Ranma's insensitive father. Long ago, when he and Soun were training under Happosai, he arranged with Soun Tendo, that their children would someday marry. While training Ranma at the remote Chinese training ground Jusenkyo, Ranma kicked him into Shonmaoniichuan where a panda drowned 2000 years ago (Very tragic story. ^_^). To Ranma's shock, Genma emerged as a panda. As the guide explained the tragic legend of the spring, Genma whacked the distracted Ranma into Nyanniichuan.
Unlike Ranma, he doesn't have much trouble with his curse, and becomes quite accustomed to living as a panda (comporting himself with human dignity even as he sips tea and plays shogi with Soun). Since he can't speak as a panda, he uses wooden signs to communicate.
Distinctive features: Round glasses with loops around each ear. Weapons: As a panda, wooden signs. Name: "dark horse"
