Doraemon and his adventures have become a well-loved cartoon by many growing up in the 1980s and 1990s. It continues to remain popular till today

It doesn’t matter what your age is: young, adult or old, either we accept or feel the shame of seeing Doraemon now at adult age but you all have to admit that Doraemon was, is and probably will be the one of the iconic cartoon series in the history. Where the capability of the human brain can think and designed some futuristic ideas. This cartoon series also helps to develop the imagination power of your child.

Doraemon’s story begins in the 22nd Century. During the time of production of Doraemon, there was some malfunctioning, He used to do all the work wrong and not perfectly, so he was sent to the engineer who used to repair the robots but during the time in the factory, a mouse robot ate his ears, Thus now Doraemon has no ears, and this is why he used to scare a lot form mouse. In the fear of the mouse and the pain of losing his ears, His yellow-coloured is completely washed due to his fear and tears. So this is why Doraemon is blue and have no ears.

As Doraemon was a defective product and of no use so the company decided to auction it. During the auction, no one wants to buy it because of its condition so it was sold at a very cheap price to a very poor family. The family of Sewashi’s (Nobita’s great-grandson’s to great grandson's). They were living a very poor and miserable life due to the huge debts inherited from their great, great, great grandfather. Sewashi come with an idea and decided this could not go on like that.  So he decided to send Doraemon to the past where Nobita is living, as Nobita is the originating point for their present condition just because of Nobita’s lazy, poor and dumb character.

So, he sent Doraemon back to the past in order to help Nobita become a nice and successful person so in the coming future his family did not have to live the present horrible life. The idea was that this would change the future and so improve the family’s lot in life.
