A nine-year-old kid gets dropped into a dying god realm and has to save it with nothing but a clay robot he keeps accidentally breaking. The show treats this premise with complete sincerity, no winking at the absurdity, no apologies for the scale mismatch between a child and apocalypse. He fails constantly, learns nothing particularly profound, and keeps going anyway because someone has to. The magic here isn't in the world-building or the mecha design; it's watching a kid discover that saving the world is just another problem you solve by showing up tomorrow and trying again. Made in 1988 for an audience that didn't need their heroes to be qualified or their victories guaranteed.
Wataru Ikusabe is a young boy who is magically carried off to Soukaizan, a realm of the gods, and is expected to save it. The land suffers under the oppression of an evil magician, and Wataru sets out on a quest to free it. Along the way he turns a clay sculpture into a small, partly autonomous super robot, which he pilots in battle. The robot is huge yet drawn in a comical, super-deformed style. The result is a 1988 television adventure that mixes mecha action and science fiction with plenty of comedy, and it proved popular enough to be remade later as Chou Majin Eiyuuden Wataru.
