Arale Norimaki is an android created by Senbei Norimaki in Penguin Village. Designed as a humanoid robot resembling a young girl, Senbei intended her to pass as human. Persistent nearsightedness necessitates her corrective glasses, a trait retained due to reader appreciation for the representation. Depicted with purple hair in most iterations, her design evolved to appear younger and shorter during the original manga, featuring brown hair in the 1997 anime. She exhibits a naive, energetic, childlike personality. Her signature expressions include "N'cha" (greeting), "Bye'cha" (farewell), "Hoyoyo" (bewilderment), and emitting a "Kiiin" sound while running with airplane-style arms. Academically intelligent and skilled in problem-solving, capable of advanced mathematics and surgery, she nonetheless lacks common sense and social awareness, frequently misunderstanding human customs. Her interests encompass Japanese superhero media, monster films, and a noted fascination with poking feces with sticks. Arale possesses immense superhuman strength, enabling feats like splitting the Earth with a punch ("Chikyūwari"), firing energy beams ("N'chahō"), and surviving extreme trauma, though she remains oblivious to the consequences of her power. Senbei presents her as his younger sister or daughter within Penguin Village to conceal her android nature, though behaviors like detaching her head or displaying inhuman strength strain this secrecy. She befriends rebellious classmates Akane Kimidori and Taro Soramame, joining Akane's "Sukeban Deka Fan Club" after excelling in school clubs. Her family expands when Senbei marries teacher Midori Yamabuki, and they adopt Gatchan, a winged creature from a prehistoric egg. Arale later marries Obotchaman, with future timelines showing them raising a child together. Key adventures involve thwarting villains like Senbei's rival, Dr. Mashirito, and extraterrestrial threats such as King Nikochan, whose ship is eaten by Gatchan. She travels through time using Senbei's "Mr. Time" invention, visits prehistoric eras, and interacts with historical figures. In crossovers with the Dragon Ball series, she defeats General Blue, aids Son Goku, and battles Goku and Vegeta in *Dragon Ball Super*, matching Super Saiyan Blue-level power through her defiance of gag-manga physics. Appearances extend beyond core media to a 2007 short film and video games like *Jump Super Stars* and *Dragon Ball Z: Budokai Tenkaichi 3*. In the film *Dr. Slump & Arale-chan: Hoyoyo! The City of Dreams, Mechapolis*, she participates in events within the titular city. Her character design and abilities remain consistent across the franchise.
