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 user into an "Quake Man", allowing them to create shock waves (or "quakes"). Gura Gura comes from a Japanese onomatopoeia which means unstable or shaking. It was eaten by Edward Newgate.

Strengths and Weaknesses
This fruit's major strength is that it allows user to generate massive shock waves, which can either be in the ground, under the seafloor, or even in the air. Because of this, Fleet Admiral Sengoku has stated that Whitebeard holds the power to destroy the world. It is so powerful that even other places far away from the battle can feel the earthquakes.

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

Usage
Whitebeard activates his powers by punching the air, which causes it to crack like glass. When that happens, a massive shock wave is released. Whitebeard has shown to create earthquakes under the seafloor, which caused the ocean water to form massive waves. He also caused such shock waves in the air, which shattered the airborne ice-bodied Aokiji. The user can utilize his quake powers in close combat using concentrated shockwaves, as seen on Vice-Admiral Ronse.

Trivia

 * This Devil Fruit's name is reminiscent of Whitebeard's laughter style, "Gurarara". This attribute is shared with Perona's Horo Horo no Mi.
 * The Gura Gura no Mi's powers make Whitebeard resemble the Greek God Poseidon, as the Emperor of the Seas who could cause earthquakes and tsunamis.
