Pamu Pamu no Mi

The Bamu Bamu no Mi is a Paramecia class Devil Fruit that allows the user to cause anything they touch to rupture and explode, turning them into a Rupture Human (破裂人間). It was eaten by Gladius.

Strength and Weaknesses
The main strength of this power is that it allows the user to cause anything they touch to swell up, which will then rupture and explode violently, including their own body parts. By doing so with their own body parts, they remain unharmed from the explosion.

This fruit has no known weaknesses, aside the standard Devil Fruit weaknesses.

Usage
Gladius basically uses this ability for combat. He can cause his own arms to bulk up and explode while grabbing onto his opponents, causing explosive damage, or cause grab onto an opponent and cause them to rupture. Gladius can also use the explosion to fire off shrapnel from the resulting explosion.

Trivia

 * This ability is very similar to the Bomu Bomu no Mi, as they both involve explosions.
