Preta Path

The grants the user the ability to absorb any chakra based attack using the Blocking Technique Absorption Seal, the user could absorb an infinite amount of chakra in any form. This power was channelled into one of Nagato's Six Paths of Pain.

Nagato's Preta Path
While alive, Nagato used this technique through a corpse that he controlled due to his lack of mobility. When he was alive, the Preta Path belonged to a large, bulky man originated from Kusagakure. The anime showed that he was both a ninja and a farmer who'd failed to cultivate their land for his family due to his participation in the Second Shinobi World War. The Preta Path, like all of the Six Paths, possessed Nagato's Rinnegan. It had orange hair tied in a short ponytail. It had small spiked piercings covering its entire bottom lip, two vertical spike studs on the front of his nose, two spike studs (one on each cheek), a metal spike going through each ear, and a stud on his shoulder, one on each side, close to his neck.

This path's "chakra absorption" ability was primarily defensive, since it was capable of absorbing any ninjutsu-related technique, thereby nullifying its effect. This technique could also take the form of a barrier around its body, allowing it to absorb attacks from all directions.

In addition to its defensive properties, this body's ability had also shown offensive capabilities, as it could absorb all the chakra out of any person that it touched or grabbed. It was incapacitated and petrified during the invasion of Pain after it absorbed too much of Naruto Uzumaki's senjutsu chakra and turned into a toad statue.

Influences
In Buddhism, the Preta realm (also known as the Hungry Ghost realm) is a reincarnation based on strong possessiveness and desire which were cultivated in a previous life or lives. The Preta are humanoid creatures which are perpetually hungry and thirsty, but are unable to sate 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.
