Ever find yourself deep in a 'Naruto' wiki rabbit hole at 2 AM? That's where the Otsutsuki details live. Their origin isn't laid out in a tidy flashback; it's pieced together from 'Shippuden' finale crumbs, 'The Last', and the 'Boruto' era, mostly through Kaguya and Momoshiki's monologues. They're basically cosmic parasites, traveling from world to world to plant God Trees and harvest the chakra fruit. The whole thing feels like it got retconned in to explain the source of chakra itself, turning the Sage of Six Paths' myth into an alien invasion story. I kind of miss when chakra felt more mystical and less like an intergalactic resource farm.
Honestly, the lore can get contradictory. One minute they're a clan with a hierarchy, the next they're just pairs of 'planters' and 'vessels'. The whole 'Boruto' expansion with the Ōtsutsuki God and Isshiki felt like they were making it up as they went, trying to top the previous big bad. It's cool for power scaling but narratively messy. I still find their design and the idea of them being behind everything intriguing, even if the execution feels a bit like an afterthought.
