Arale Norimaki is an android constructed by Senbei Norimaki in Penguin Village, designed as a young girl-shaped robot. Despite Senbei's goal of perfection, Arale is severely nearsighted and requires corrective glasses, a trait retained due to positive reader response regarding representation. Her appearance typically features purple hair and glasses, though her design evolved to look younger over time; this change was later explained as multiple bodies of varying sizes. Arale wields superhuman strength and durability, demonstrated by feats such as splitting the Earth with a punch, effortlessly destroying trees or poles, surviving gunfire to the face with only her glasses damaged, and throwing rocks that break the moon. She exhibits advanced intelligence, solving complex math equations or performing medical procedures, yet displays profound naiveté and a lack of common sense. Her personality is energetic, playful, and childlike, with interests encompassing Japanese superhero shows like Ultraman, monster films like Godzilla, and a recurring fascination with poking feces with sticks. She uses unique phrases like "N'cha" for greeting, "Bye'cha" for farewell, and "Hoyoyo" expressing bewilderment, and runs with arms extended while yelling "Kiiin". Senbei initially introduced Arale as his sister or daughter to conceal her android nature. She enrolled at Penguin Village Middle School, befriending rebellious teen Akane Kimidori and "bad boy" Taro Soramame after demonstrating her strength. Key life events include discovering she lacks a belly button, prompting Senbei to invent See-Thru Glasses to study anatomy; adopting Gatchan, a winged creature hatched from a prehistoric egg that eats metal and later splits into two beings; and gaining a stepmother, Midori Yamabuki, and brother, Turbo, following Senbei's marriage. Her adventures involve time travel via Senbei's inventions, unintentional property destruction, and encounters with antagonists like bank robbers or aliens, often resolved through her oblivious application of strength. In *The Secret of Nanaba Castle*, Arale pursues the stolen "Eye of Rainbow" treasure after Bisna, a descendant of the Nanaba Kingdom, takes it to revive a devil and restore the kingdom. She journeys to Nanaba Castle with friends to confront Bisna and retrieve the artifact. Beyond her main series, Arale appears in *Dragon Ball* during Goku's pursuit of General Blue, effortlessly defeating Blue and demonstrating purity by riding the Kinto'un cloud. She later features in *Dragon Ball Super*, where her gag-based abilities overpower Goku and Vegeta. She also stars in crossover video games such as *Jump Super Stars* and *Dragon Ball* titles, alongside commercials for Suzuki cars and clothing brands.
