Preta Path

The grants the user the ability to absorb chakra in any form using the Blocking Technique Absorption Seal. Pain channelled the Preta Path through the corpse of a Kusagakure shinobi.

This ability was primarily defensive in nature as it is capable of absorbing ninjutsu-based techniques, thereby nullifying its effect. This technique can also take the form of a barrier around the user's entire body, allowing them to absorb attacks from all directions. In addition to this, the Preta Path is able to absorb chakra from an individual through physical contact.

Although the user is still vulnerable to the effects of turning into a stone stature from absorbing too much senjutsu chakra.

The Preta are humanoid creatures which are perpetually hungry and thirsty, but are unable to satisfy themselves, living lives similar to those of hopeless addicts trying to appease their unyielding hunger. In appearance, the Preta are deathly pale, emaciated figures, which contrasts with Pain's Preta Path's hefty stature.
