Baku Baku no Mi

Wapol holds this Paramecia fruit, which in Western releases carries the label Munch-Munch Fruit after the crunching noise its powers produce. Its violet, plum-like shell splits down the middle in a jagged line that suggests an open mouth, sitting above a coiled green stem and swirled orange flesh.

Consumed matter becomes raw material for weapons, disguises, or hybrid creations, since the fruit works by merging the eaten with the eater. The old saying about becoming what one eats sums up its logic rather neatly.

The wielder's jaw can widen enormously, and reinforced teeth plus a hardened gut let them chew and digest things no ordinary person could survive, whether metal, poison, or a fellow human. Any portion of the body can then be reshaped into a copy of something already swallowed, so a limb might turn into a cannon, or two devoured beings might be welded into a single new one.

The trade-off is a hunger that no meal ever settles, and springy materials such as rubber go down with difficulty. Only items eaten within the previous day can be recalled; anything older is lost. All the usual Devil Fruit vulnerabilities apply, and Seastone is assumed to shut the ability off.

Wapol is the sole canonical eater. He gorged on knives, entire houses, and once shielded his retainers Chess and Kuromarimo from an avalanche by holding them safely inside his mouth. His combat moves include Baku Baku Shock, which grafts eaten weapons onto his frame, and the transformations Wapol House and Bero Cannon; his Ningen Heiki form, built from an armory of weapons, felled Dalton.

After Luffy beat him, Wapol turned to a gentler use, the Baku Baku Factory, fusing swallowed junk into toys for income. Scientists later found a novel metal, dubbed Wapometal, inside those products. In the ninth film he briefly gained a second fruit power by eating his brother Musshuru, a non-canon first for the series.
