Human Hibernation

A style of combat used by those is Perfect Wolverine Sage Mode in which the user surrenders control of themselves for a fierce side to come forth in the form of natural energy and fight for them. It has been compared to the Drunken Fist in that no one can control themselves once they enter it. Also compared to Feigning Sleep Technique, but unlike such a technique, Human Hibernation can only deactivate once out of Sage Mode.

This technique can be coupled with the Eight Gates, though it only up to the fourth Gate. When combined, the movements are massive and just about match up to having the seventh Gate Open while in Sage Mode.

Hand Seal
This technique uses a unique hand seal only known by the Sage of Snowy Valley. The user first grows massive claws, either from their Sage Mode or Claw Creation Technique, and digs their hands into the ground. Underground, they form their hands into two partial fists and lay them on top of each other (right hand on top), with their thumbs tucked under one another. This draws in and traps the natural energy.
