Doraemon (1979)

Nobita Nobi is a lazy, unlucky schoolboy whose poor grades and constant mistakes will eventually leave his descendants in poverty. To prevent that future, they send Doraemon, a blue robotic cat from the 22nd century, back through Nobita's desk drawer to guide him toward a better life.

Doraemon's four-dimensional pocket contains gadgets capable of solving almost any problem, from instant travel to impossible transformations. Unfortunately, Nobita usually borrows them for shortcuts, revenge, or showing off, creating a larger mess than the one he wanted to fix. Between those disasters, Doraemon becomes less a supervisor and more the friend who stays beside Nobita while he slowly learns to face life on his own.
