Ōtsutsuki Clan's God Tree

A God Tree is a type of gigantic tree which grows by absorbing blood soaked into the ground from countless battles over a millennia. Due to its massive size and the conditions under which it is grown, the God Tree is revered by some cultures; humans used to worship its God Tree as a sacred pillar that extended into the heavens and remained ambivalent to all conflict.

In the anime, a God Tree seed landed on Earth from a meteorite several millennia ago. It was believed that the God Tree nourished the land and helped it thrive, while in truth, the God Tree was slowly killing the land and its people, by draining natural energy from them. It was believed that anyone who approached the tree was consumed by a demon spirit and died like a withered branch.

Every thousand years, a God Tree produces a "chakra fruit" which human legend holds are never to be touched. Members of the Ootsutsuki travel through dimensions in search of God Trees so that they can consume these fruits and gain their powerful chakra for themselves. Some Ōtsutsuki, such as Momoshiki and Kinshiki, harvest the God Tree's fruit until it and its respective planet die, at which point they go looking for a new one. Kaguya, after consuming the fruit of Earth's God Tree, chose to settle on the planet and use the power she gained in order to single-handedly rule over the human populations.

The Furutani and Tōtoi clans of the Summer Country realized that when the Ootsutsuki clan stole the fruit of their God Trees, the seed was infected and therefore dangerous, resulting in the Trees killing planets and other organisms.
