Ten-Tails (Seeds)

The are the seeds that grow into God Trees the Ōtsutsuki clan uses to drain all the chakra from planets to create chakra fruits for them to use. The process is that the Ōtsutsuki has the Ten-Tails core its way into the victim planet's center, where it would then spread its roots throughout the entire world to reach every corner, sparing no one from its harvest. This results in all life on the planet dying as well as the planet itself. Because of the nature of which the Ōtsutsuki uses these Ten-Tails, Amado has referred to the clan as parasites.

Trivia

 * Unlike others, the Ten-Tails utilised by Kaguya Ōtsutsuki did not completely drain the planet dry even after producing a chakra fruit for Kaguya to consume. Why this occurred instead remains unknown, but a mad Kaguya would eventually merge with said Ten-Tails in a jealous rage when she discovered her twin sons were born with chakra. Upon her return, Kaguya used the God Tree in an attempt to retake the chakra that had since then spread across the elemental countries.
