So first tell me all you know of Doton, its weaknesses and strengths. Also any and all physical divergence and characteristics you've seen.
Lastly, name me three profound users of Earth Release from the manga/anime.
Earth style is one of the basic five elemental natures. Though more of a defensive element than offensive, it deals with types that include the manipulation of rock, dirt, mud, and one some cases, sand. It is weak to lightning because of its cutting power and strong against water since it can absorb it. However when it soaks up too much water it becomes mud and loses its strength. Earth style is a component of several bloodline limits (kekkei genkai & kekkei tota) which include:
Lava = Earth & Fire
Wood = Earth & Water
Blast = Earth & Lightning
Dust = Earth & Fire & Wind
Wiki says that it is also the component of Crystal and Magnet release but not sure if it is true or just speculation. Earth style has been shown to have the ability to change density, going from hard as metal or soft as sand.
There's a lot of earth users but the one's that stand out to me are Oonoki, Gaara (casuse of the sand), and Kurotsuchi. Special mentions to Yamato, Hashirama, and Muu.
