Genma Saotome

Genma Saotome is very much like his son, Ranma. He is somewhat arrogant when it comes to his martial arts abilities, which he rarely showcases due to cowardice or laziness. It was Genma that took Ranma to Jusenkyo. Because he was unable to read the pamphlet, which was in Chinese, he had no idea of the curses that existed there.
When splashed with cold water Genma transforms into a panda. When in this form, he uses signs with written messages on them to communicate. Although he often tries to rid himself of his curse, he doesn't seem to mind it as much as Jusenkyo's other victims. Most of Genma's time is spent sitting around the Tendo home playing Go with his best friend Soun.
