The Sage Art: Reptilian Transformation Technique is utilized by the lizard sages of Kuroishi Island, which allows them to use natural energy to transform into a more human-like form. While in human form, the user's strength, speed and agility are augmented by the natural energy, while simultaneously giving access to a body more suited for combat. Conversely a human with extensive knowledge of lizard Senjutsu can use this technique to turn into a lizard with the senjutsu enhancing their abilities.
