Tsuchi Tsuchi no Mi (Wg4)

Introduction
The Earth Earth Fruit is a powerful Logia class Devil Fruit, eaten by the dethroned former king of Pleasure Island, Majestic T. Decaden. Being a Logia type Devil Fruit, this grants Decaden the power to become, generate, and manipulate any earthy substances related to the ground itself. As such, Decaden is capable of launching large rocks and boulders at his enemies, and can be as hard as stone if he wishes to be. What's more, is that he can generate and create various weaponry and armor out of his stone-like body, and transform his mass into any shape or form he wants, thus making him an already formidable foe to deal with. However, as the Earth Earth Fruit is a Logia Devil Fruit, this also means that Decaden possesses the nigh-invulnerability that Devil Fruits such as these grant their users. This makes nearly all forms of attack useless against Decaden, making him a fearsome foe in combat. With this power, he managed to secure his tyrranical rule over his kingdom until he was dethroned by Jolly D. Chris, along with the help of a strong pirate crew.
