Yao is the self-appointed leader of the trio. His signature color is red in the first film and purple in the second film. An arrogant and short-tempered individual with a bit of a Napoleon complex, he is short, stocky and has a permanent black eye. In the first film, he enjoys picking on Mulan for fun at first, but eventually becomes her friend. His clumsiness reveals, however, that he is not as powerful a man as he claims to be. He states about wanting a girl who'd admire his strength and battle scars.
In the second film, he reveals a rewarding plaque that has a picture of himself on his chest and falls in love with Princess Mei, the emperor's middle daughter. She accepted the idea that "my duty is to my heart" and is the easiest to be won over. In his encounter, he puts the slipper back onto her foot and sets the table for her with oranges, meat buns and tea. He wanted to marry a girl who would be impressed with his looks and his fighting ability. Although such traits leave something to be desired, he managed to impress her, and when he wins a fight at a carnival and is given a prize, he chooses a stuffed panda bear with three black legs and one white leg and gives it to her.
