Arale Norimaki is an android created by inventor Senbei Norimaki in Penguin Village. Designed to resemble a young girl, she has severe nearsightedness and requires corrective glasses. She typically has purple hair and a childlike, energetic, and naive personality. Senbei presents her as his younger sister or daughter to conceal her android nature. Arale uses unique phrases such as N'cha for greeting, Bye'cha for farewell, Hoyoyo to express bewilderment, and makes a Kiiin sound while running with her arms outstretched. Despite high intelligence and problem-solving skills, she lacks common sense and social awareness. Her interests include Japanese superhero shows, monster films, and poking feces with sticks. Arale possesses immense superhuman strength, enabling feats like splitting the Earth with a punch and firing energy beams. She enrolls in Penguin Village Middle School, befriending Akane Kimidori and Taro Soramame. She adopts Gatchan, a winged creature hatched from a prehistoric egg. Her family expands when Senbei marries Midori Yamabuki, and later she marries Obotchaman. In crossovers with the Dragon Ball series, she defeats General Blue and rides the Kinto'un cloud due to her pure heart. Her adventures include traveling through time, confronting villains like Dr. Mashirito and alien king Nikochan, and visiting places such as the city of Mechapolis and Nanaba Castle.
