Bane Bane no Mi

The Bane Bane no Mi, also known as the Bane Bane Fruit, is a Paramecia type Devil Fruit that allows the user to turn their legs into springs. It is unknown whether the rest of the body can be changed as well. "Bane" means spring. In the 4kids adaption, it is called the Spring Spring Fruit. It was eaten by Bellamy the Hyena. The power of the fruit was foreshadowed with the state of the site where Roshio was killed. The fruit's actual power was revealed when Bellamy and his crew attacked the leaders of the Saruyama Alliance in order to steal Montblanc Cricket's gold.

Strengths and Weaknesses
The major, if not only, strength of the fruit, as demonstrated by Bellamy, is that it gives it's user amazing jumping and bouncing power. With this the user is able to launch themselves at incredible speeds in order to deliver attacks enhanced by the velocity of their momentum. The fruit so far doesn't seem to have any specific weaknesses outside the standard Devil Fruit weaknesses.

Usage
The fruit's bestowed powers, as used by Bellamy, have been used primarily for combat. The basic concept is that Bellamy turns his legs into springs and then launches himself to attack an opponent. Outside of combat purposes, the fruit's powers have been seen being used by Bellamy to jump to top of tower where Luffy was calling out for him. Other than that, any other use the fruit may have outside of combat purposes is currently unknown. The techniques that are used by Bellamy that involve the Devil Fruit are as follows:


 * Spring Snipe: Turning both his legs into springs, Bellamy launches himself directly at his opponent with a punch. This was first seen being used on Shoujou when Bellamy and his crew attacked the Saruyama Alliance leaders.


 * Spring Hopper: Bellamy's ultimate attack. Using the surrounding geography like the buildings in Jaya's square, he bounces from one spot to the next, increasing in speed with each successive spring, also disorientating opponents with the continuous sound of springing. Then he simply has to aim himself at the target and let his velocity do the rest. This is the tehnique Bellamy used to kill Roshio and was first properly seen when he battled against Luffy.
