Arale Norimaki is the main protagonist to the Dr. Slump series created by Akira Toriyama, and as well as a minor character in the Dragon Ball manga and anime. She is an android built by Senbei Norimaki, known for her naiveté, energetic personality, superhuman strength, and lack of common sense. She is also nearsighted and needs to wear glasses. Senbei's mission is to convince the other citizens of Penguin Village that Arale is no more than a typical 13-year-old girl, which they appear to believe in, despite taking notice to Arale's numerous displays of superhuman athletic capability.
Akira Toriyama was told to put in a robot as the co-lead by his editor Kazuhiko Torishima when he mentioned that he wanted to make a manga about a doctor. Initially Toriyama planned on making the robot big, but decided that it would end up being too big to fit in the panels and decided to make it small. Torishima did not like the idea and so Toriyama created the robot girl Arale since Torishima liked girls a lot
