Hydrification Technique

The user can reduce all or part of their body to a watery form, avoiding and absorbing attacks. They re-solidify at will. Using this, the user can also re-shape their body parts for suitable situations. When the user passes out, they are turned into a jelly-like state. It is unclear whether or not this is a product of Orochimaru's experimentation, or if it is Suigetsu's natural ability.

As this technique turns Suigetsu's body into water, he is vulnerable to lightning techniques. When he was pinned down by Darui's sword, imbued with electricity, Suigetsu notes that he couldn't liquidize properly. He also seems to be easy to contain while in liquid form, as he couldn't escape from the holding container in Orochimaru's laboratory until Sasuke opened it for him.

Trivia

 * A similar technique was utilized by the Chunin who attacked Team Kakashi when they were escorting Tazuna.
