Gura Gura no Mi

The Gura Gura no Mi, also known as the Gura Gura Fruit, is a Paramecia-type Devil Fruit that turns the eater into an "Earthquake Man", allowing them to generate earthquakes. It was eaten by Edward Newgate.

Strengths and Weaknesses
This fruit's major strength is that it allows Whitebeard to generate earthquakes. These tremors can occur even at the ocean floor, thus creating tsunamis. Fleet Admiral Sengoku has stated that Whitebeard had the power to destroy the world. As it apparently has the power to destroy the world, it is by far the strongest Devil Fruit yet introduced.

This Devil Fruit has no apparent weaknesses, aside from the standard Devil Fruit weaknesses.

Usage
Whitebeard has shown to generate massive earthquakes with this power. He is also able to create seismic waves in the ocean floor, forcing the seawater to a massive tidal wave. When in use, Newgate moves his arms and literally breaks part of the air like a window, creating the earthquake.

Trivia

 * Ironically, his Devil Fruit's name is reminiscent of his laughter style, "Gurarara". This attribute is shared with Perona's Horo Horo no Mi.
