Doraemon (1979)

A fourth-grade boy in Tokyo, Nobita Nobi, discovers a blue, round robot resembling a cat without ears inside his desk drawer. This robot, Doraemon, is sent from the 22nd century by Nobita's descendant, whose family suffers from poverty due to Nobita's past mistakes. Doraemon's mission is to prevent these errors, though Nobita is often the weakest and least intelligent in his class. The robot possesses a 4-dimensional pocket containing futuristic gadgets intended to assist Nobita. However, Nobita frequently misuses these tools, leading to further complications.
