Doraemon is a cat-shaped robot from the future who travels all the way back to the 20th century to help Nobi Nobita, a lazy kid with nothing really going for him. Nobita is bad at sports, his grades are terrible, and he can't even win a match of rock-paper-scissors. Doraemon has a hard task ahead of him, but he is well prepared with a huge arsenal of the most inventive and funny gadgets available. The problem is that he's not the most competent robot cat helper out there either, and the pair gets in constant trouble because of it. Thus begins one of the most interesting friendships ever to appear in a manga series.
