Ryoga Hibiki 響 良牙 is Ranma's long time, primary rival, and the only one the latter has self stated to be so, and arguably the third main character of the series. He has no sense of direction and is always lost on long strenuous journeys. After spending months looking for male Ranma for leaving before their planned duel, Ryoga finally ends up at Jusenkyo in China, but is pushed into a cursed spring by female Ranma (while chasing Genma and not looking where she was going). Ever since then Ryoga turns into a black piglet when doused with cold water, which makes his constant wanderings much more dangerous from hungry hunters and predators, and he initially carries a large grudge.
