Mayfly

This infiltration technique is a characteristic of Zetsu. It allows him to merge his body with the ground and flora and travel at very high speeds. His insectivorous plant-like shell has the ability to merge with the ground, because it is tinged with his chakra. Then, using the underground network of organic matter, consisting of things like plant roots and water veins, he can travel everywhere with high speeds. Using this technique he can conceal himself in trees and even sand. Once merged, his presence is completely concealed, making it almost impossible to detect him, even by sensory type ninja like Karin. This makes this jutsu perfect for up-close spying.
