Bane Bane no Mi

Eaten by Bellamy, this Paramecia fruit lets its owner convert body parts into springs, which is why he is called a Spring Human. Western releases first named it the Boing-Boing Fruit before settling on Spring-Spring Fruit, the term also used in the Funimation versions.

An early hint of the power appeared in the wreckage left where Roshio was beaten, and its true nature came out when Bellamy's crew attacked the Saruyama Alliance's leaders in a bid to seize Mont Blanc Cricket's gold.

Coiling his legs lets Bellamy hurl himself forward so quickly that opponents often cannot track the motion, building heavy momentum as he closes in. The recoil from bouncing off hard ground is strong enough to shatter those surfaces; the Going Merry was cleaved apart this way. Springing his arms instead produces longer, harder punches.

The approach has clear limits. Leg-launched movement travels only in a straight line, so a foe who reads the path can counter, and a fast counter meets him at his own dangerous speed. He also needs solid footing and room to work, making the terrain decisive, and his bouncing can wreck the surroundings. Standard Devil Fruit weaknesses round out the drawbacks.

Bellamy uses the fruit almost entirely for fighting, and his style shifted across the timeskip. Before it, he mainly turned his legs to springs and flew fist-first at targets; Spring Snipe drove a direct leaping punch, while his ultimate Spring Hopper had him ricochet off buildings, gathering speed until he nearly vanished from sight, though Luffy eventually read it and struck him mid-flight.

Afterward he refined his control, springing a single arm for reinforced blows, merging both legs into one coil for acrobatics, and stretching his limbs like Luffy's rubber. Spring Death Knock, a compressed spring-arm punch that echoes the Gomu Gomu no Pistol, debuted at the Corrida Colosseum against Tank Lepanto.
