Earth Prison Golem

This was the personal summon of Jirōbō of the Sound Four.

Appearance
It is a gargantuan stone construct with huge limbs and a single eye closer to the left side of its face.

Abilities
As noted by Chōji Akimichi and Shikamaru Nara, the golem also possessed the ability to absorb chakra from its targets, just like its summoner. It also has the ability to regenerate from damage inflicted upon it. Due to its large, stone body, it also had great physical strength, enough to stop Kiba and Akamaru's Fang Passing Fang with its bare hands.

Shinobi World War Arc
The earthen golem was summoned by a reincarnated Jirōbō alongside the other Sound Four members' respective summons during the Fourth Shinobi World War.
