The Eight-Tailed Beast is currently one of the two remaining Tailed Beasts that was not extracted by Akatsuki, while the other one being the Nine-Tailed Demon Fox. Due to Akatsuki's depleted numbers, Madara Uchiha ordered Team Hawk to capture the Eight-Tailed Beast. The Jinchūriki is a musclebound Cloud shinobi who appears to dislike light. He also carries seven swords.On his right shoulder he has a tatoo that says "iron", and on his left cheek he has a tattoo of a bull's horn.

Speculation
As most of the other Tailed Beasts are based upon mythological creatures, it is speculated that the Tailed Beast is based upon the eight-headed and eight-tailed dragon, Yamata no Orochi. But from the shadow when Sasuke goes to retrieve the beast, it seems to be an octopus.

There is a resemblance of this beast's host to Hulk Hogan.
