Nagare created the Assimilate All Creation Technique, in which he is able to absorb the properties of any nerby object and manipulate it through his will alone. As seen with fight against Kakashi, Nagare took on the properties of stone. Not only was he able to manipulate the stone around him, but was able to turn into stone himself while producing large quantities from it. Also, by taking on the properties of stone, he was able to use the Assimilated Rock Blizzard to use stones as projectiles, and the Assimilated Rock Tank to expand using stone and crush the opponent while rolling with great force. He could also control rock powder similarly to Gaara's sand, engulfing the opponent with rock powder by using Assimilated Sand Binding Coffin and crushing them with Assimilated Sand Waterfall Funeral.
