A feral newly reborn unintelligent Thanos running at "arguably" 50% of his capabilities turned the capital planet of the Universal Church of Truth without any tech, into a wasteland.
A race who harnessed faith as a power-source and had "Cardinals" who with force of Intent could make beings lose their minds or do anything they wished.
Think of them as a race of Jesse Custers. And Thanos obliterated them.
I loved Naruto and am struggling to see how the land amasses a force that can corner and take him down before he obliterates them.
