After training with his father Genma at Jusenkyo in China, Ranma fell into the cursed spring Nyanniichuan—and came out as a girl. Now he's stuck with a gender-swapping curse that responds to temperature: hot water turns him back into a boy, but cold water (or anything cool) transforms him into a girl again. It's become the defining feature of his life, though martial arts is really what matters to him.
At 16, Ranma's got serious skill in fighting, but his ego is even bigger. He's convinced that physical strength is basically all he's got going for him, which means any hit to his pride hits hard. When someone challenges that, he'll do almost anything to prove himself—even when it's obviously a bad idea. Fans often note that this stubborn streak gets him into trouble as much as his curse does.
