Ranma Saotome is the main character of Ranma ½. He is the fiancé of Akane Tendo.
He has black hair with pig-tailed.
When he is in girl form, he has red hair (in the anime; it remains black in the manga).
He is very much in love with Akane, but does not want to admit it. When another man shows general interest in her, he can't help but grow jealous leading him to becoming depressed, scheming something to separate them, or growing worried.
Whenever his pride is damaged, Ranma will go to great lengths to rectify the situation. He can come across as petty, arrogant, and disrespectful, as he is prone to bragging and tossing insults. Despite these flaws, he retains a moral center throughout the series and has little to no problems helping those in need.
He is a 16-year-old proficient martial artist, he spent most of his youth on training trips with his father. The last of these trips led them to Jusenkyo, China, where he fell into the Spring of Drowned Girl and changed into a well-built girl. Since then, he changes to this girl form any time he is doused with cold water, while hot water returns him to a boy. Thanks to an agreement between his father and Soun Tendo, he is engaged to Soun's daughter Akane. Due to a series of other involuntary entanglements, he has several additional love interests, most notably the Chinese Amazon Shampoo, okonomiyaki chef and childhood friend Ukyo Kuonji, and Kodachi Kuno, the younger sister of rival Tatewaki Kuno.
