Metal Assimilation

Metal Assimilation (金同化, Kin Dōka) is one of the three main defensive techniques created by the Kinsei Clan. This technique is based upon changing one's biological structure to metal. An advanced form of self-transmutation. As was seen by the Hydrification Technique and Earth Release: Earth Spear, the users turns their body into a certain object to attain specific properties. This technique is used without the requirement of hand seals. The user can turn themselves to any metal that they can utilize. Their whole body would be composed of metal meaning that they are seemingly invulnerable. The user can turn himself into techniques or merge with them. As was seen with Saizen Kinsei, he turned himself into Metal Dust and manipulated himself. He also used this technique to turn into Elastium, making any force, no matter how strong, useless against him.

The user can also manipulate their body in order to become extensions. They can stretch their arms and limbs to get a larger reach as well as create limbs from their bodies such as arms or tentacles that morph from their back or other body parts. In this state, the user can magnify their size to be equal to the size of a tailed beast as was seen with Saizen who turned himself into a giant metal humanoid. The user can also enlarge specific parts of their body to suit the situation that they're in. If the user is skilled with this technique, they can do partial transformations to transform parts of their body to metal rather than their whole entire body.
