Oobleck Body Technique

Utilizing Yin and Water Release in unison, Sadao is able to convert his body into a solid, liquid or gaseous state his body when attacked, avoiding all injuries in the process. Additionally, when force is exerted on his body, it becomes harder than diamond in the process, vastly increasing his durability. Using this method, Sadao is able to avoid all damage while making him much harder to be harmed such as when struck with a punch, a sword or even ninjutsu techniques. This technique is very resistant to lighting techniques. The user is able to liquify, solidify and gasify their body at will, while still retaining all the originally properties of the technique.

By creating Yin and Water chakra throughout his whole body, or individual parts, Sadao is able to separate parts of his body, leaving behind nothing in its wake as his body in converted into a black, flashing liquid. This allows him to avoid attacks and harm completely, while enabling him to escape confines. Like a similar technique, he can inhibit {{nw|Sensor|sensing techniques]] and even prevent himself from experiencing intense sound vibrations and sound-based techniques. When in a gaseous state, he is able to enter the body of others through the nostrils, mouth, wounds and even the pores within the skin and wreck havoc, possibly killing them in the process via rapidly corroding them from the inside-out. In a gaseous state, he is able to make a complete copy of himself via {{nw|Electrolysis}}. By shaping their body into various forms and exerting force on themselves, the user is able to force nearly indestructible blades capable of slicing through nigh-anything. If confined inside of a container while in this state, the user is able to escape by "grinding" their way out via high-speed revolution when making their body spikey.

Sadao Uchiha replicated this technique via unknown means.
