Nobita Nobi (野比 のび太 Nobi Nobita?) is the main character of the series and the center of the story. 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 on classes, scoring zeros in his tests, getting lectured by his teacher, being bullied by his classmates Gian and Suneo, falling into curbside rain gutters, being chased by dogs, and getting scolded by his mom for his sloth and poor academic results.
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). He has a tendency of acquiring a grade of zero every once out of five tests and has only scored perfect once in his lifetime.
