The point of this dissection is to break down the Gura Gura no Mi, and what makes it so infamous, and what its prior users may have accomplished.
The Gura Gura no Mi has been said to be the strongest Paramecia, and is widely feared for its world ending capabilities: “It may very well be us that meet our end here today… Because that man… HOLDS THE POWER TO DESTROY THE VERY WORLD!!!” -Sengoku
Vice Admiral Tsuru said stated that, even if she retreated to the ends of the ocean, there would be no safe place left in the world for her to go when faced with the power of the Gura Gura no Mi.
What makes it so infamous? Aren’t there other devil fruits with potential world ending abilities? A few potential that come to mind are:
Fujitora: Historically speaking, it wasn’t that big of a meteor that destroyed all life on this planet before…
If Kizaru can create or become a literal sun, or could make sun flairs, or change his spectrum of light to a more dangerous one, he could cause some issues..
A literal Black Hole… Nuff said..
Even someone like Caesar Clown could poison or mutate the atmosphere..
So if other fruits are potentially world ending… Why does the Gura Gura no Mi get the top spot? Maybe it’s not strength, but fear… Notice how it’s mostly the World Government that fears or reference the fruit as world ending?
Before I get more into my theory on prior users feats. Let’s see some of what we already know the Gura Gura no Mi can accomplish.
Probably the most feared and one if the strongest powers is the ability to create Tsunamis… In an Oceanic world, that ability is absolutely TERRIFYING!
The user can grab and shake the air or atmosphere and ocean itself!
The user can also send out shockwaves and imbue his body parts with Quake bubbles.
