Doraemon is a male robotic earless cat that travels back in time from the 22nd century to aid a preteen boy named Nobita Nobi.

Unusually, the name "Doraemon" (ドラえもん) is written in a mixture of two Japanese scripts: Katakana (ドラ) and Hiragana (えもん).

After getting his ears gnawed off by a robot mouse at the 22nd century Nobi's residence, he slipped into depression on top of a tower, where he erroneously drank a potion labeled "sadness" instead of "happiness".

Due to this malfunction, Doraemon did not do well at the robot's school and during the final presentation show, he performed badly and nobody wanted to hire him, until baby Sewashi pushed the button.

Whenever he hangs out with his friend, Mii-Chan (a cute street cat), he calls it 'important work' as an excuse for not doing chores that Nobita's mother asks him to do.

[9][10][11] Doraemon is sent back in time by a young boy named Sewashi Nobi to improve the circumstances of his great-great-grandfather, Nobita, so that his descendants may enjoy a better future.

In order to alter history and better the Nobi family's fortunes, Sewashi initially wanted to send a super-robot to protect Nobita, but with his meager allowance he could only afford an imperfectly-made factory-rejected toy: an anthropomorphic robot cat called Doraemon.

He later appeared at the video where he helped prime minister Shinzō Abe (dressed up as Mario) by planting a Warp Pipe from Shibuya Crossing to Maracanã Stadium.

[23] In his book Japan Pop: Inside the World of Japanese Popular Culture, author Timothy J. Craig wrote, "Though Doraemon is himself a high-tech product, he possesses an endearing personality that captivates young audiences.
