Nobita’s stay-at-home mother. She can be very strict, is usually seen scolding Nobita or sending him out of the house (a typical Japanese household punishment used by parents, unlike grounding which is a Western punishment). She actually loves her son very much, but is disappointed by his lazy attitude and academic failures. Several episodes involve Nobita trying to avoid his mother’s scolding by using Doraemon’s gadgets. Her maiden name is revealed to be ‘Kataoka’. She has a tendency of stopping Nobita from going out to play and force him to study. However, on cold weather days, she almost always urges Nobita to go out and play. In a couple of episodes, Nobita sees her in the past. She is proved to be braver than Nobita but as clumsy as him.
Nobita’s father and laid-back salaryman. He is very considerate of Nobita, often seen arriving home from work to placate Tamako’s anger towards Nobita; this habit may come from Nobisuke’s own childhood, since his father (and Nobita’s grandfather) was very similar to Tamako. He has trouble quitting smoking and is self-conscious about his inability to pass the driving test. He also has a poor memory, is a borderline alcoholic, and sometimes arrives home drunk from nightly business meetings. He was once an aspiring art student. He also likes golf, which most Japanese businessmen and employees play.
Doraemon is the robotic cat sent back in time by Sewashi to aid Nobita. He possesses a fourth-dimensional pocket from which he can acquire various kinds of futuristic tools, gadgets, and playthings from a future department store. Doraemon originally had ears but they were bitten off by a robotic mouse in the 22nd century. As a result, he developed a morbid fear of mice despite being a robotic cat. He also has the tendency to panic during emergencies, characterized by him frantically trying to pull out a very much-needed tool from his pocket, only to produce a huge assortment of unrelated household items.
Doraemon’s physical appearance changed as the manga progressed. At first, he was predominantly blue, with a blue tail, a white stomach, and flesh-coloured hands and feet. He also stooped, and had a body much larger than his head. In later issues, he sported a smaller body, white hands and feet, and a red tail–the appearance most identify him with today.
In “The Doraemons” story arc, it is revealed that Doraemon’s original paint color was yellow. After getting his ears gnawed off by a robot mouse, he slipped into depression on top of a tower, where he drank a potion labeled “sadness”. As he wept, the yellow color washed off and his voice changed due to the potion.
Doraemon weighs 129.3 kg (285 lbs) and measures at 129.3 cm (4’3″) tall. He is able to run at 129.3 km/h (80.3 mph) when scared and jump 129.3 m (424.2 ft) when threatened. His maximum power is 129.3 bhp. He is manufactured on September 3, 2112 (12/9/3), at the Matsushiba Robot Factory (Matsushiba Robot Factory?). Doraemon is considered a substandard product because many of his robotic features (ie. radar whiskers and cat-calling bell) malfunctioned after production. One can turn off Doraemon by pulling his balloon tail.
Doraemon’s favourite food is dorayaki (dorayaki?), a Japanese treat filled with red bean paste. Speculations led to dorayaki being the origin of his name. However, it was revealed in one of the manga chapters that his name originates from the Japanese word nora neko (???, nora neko?) for “stray cat”, and the -emon ,ending which is part of traditional Japanese names, as seen also in, for example, Ishikawa Goemon.
In the 2007 birthday episode, ‘MS-903’ is used to call Doraemon by the factory owner where Doraemon is produced.
Nobita (Nobita Nobi) is the other major character of the series. He is a fourth grader in Tokyo’s Nerima Ward and an only child. He wears glasses, a red or yellow polo shirt with a white collar, and blue shorts. Nobita’s character flaws are endless: he is lazy, uncoordinated, dim-witted, frail, plain-looking, unlucky, and bad at sports. Nobita’s typical day consists of arriving late to class, scoring zeros on his exam, getting lectured by his teacher, being bullied by classmates Gian and Suneo, falling into curbside rain gutters, being chased by dogs, and getting yelled at by his mom for refusing to do his homework.
Despite his flaws, Nobita possesses some unique talents such as his unrivaled marksmanship and ability to weave intricate string figures. Although Nobita is usually portrayed as being cowardly, he has often risked his life to help save others or even entire civilizations (as seen in full-length stories).
Shizuka (Shizuka Minamoto), usually called Shizu-chan or Shizuka-chan , is the smart, kind, and pretty neighborhood girl who is the object of Nobita’s affections. She takes baths several times a day. Somehow, Nobita always seem to unintentionally walk in on her (via the Dokodemo Door) while she is still in the bathtub. She is also known for taking piano lessons unwillingly, which is sometimes used as an excuse for declining to hang out with Nobita. Her true passions are sweet potatoes and the violin, in which her playing is as atrocious as Gian’s singing. Due to Doraemon’s intervention, Shizuka will become Nobita’s wife in the future timeline.
