Bari Bari no Mi

The Bari Bari no Mi is a Paramecia-class Devil Fruit that allows the user to generate barriers for defending or striking at will, turning the user into a Barrier Human (バリア人間). It was eaten by Bartolomeo.

Strengths and Weaknesses
The main strength of this fruit is that it allows the user to form invisible barriers. This protects the user from frontal attacks and deflects them back at the attacker, causing backlash damage to the attacker while protecting the user. The barriers are strong enough to defend against even a fishman's high-powered punch, which injured the said fishman's arm in return. Even Elizabello II's punch, which could allegedly take down a Yonko, could not breach the shield. The shield can also be used for offensive purposes, launching forward to create powerful forces to strike down the targets.

It is unknown if the barriers have a damage limit to break out, but it appears to only react to striking motions as Bellamy was able to touch Bartolomeo with an outstretched hand, rather than a punch. Also, it shares the same weaknesses as all Devil Fruits.

Usage
Bartolomeo basically uses this fruit's power to protect himself in combat, sitting idly by while his unsuspecting foes attack him and injure themselves. He can also use the shields offensively to strike down his targets.
 * Barrier Crash (バリアクラッシュ): Bartolomeo forms a barrier in front of himself and sends it towards enemy so fast it crushes his enemy easily. The crush is powerful enough to defeat the Elizabello II and create a shock wave. It was first shown against Elizabello in Corrida Colesseum. He also used same ability with his leg against Hack but it is unknown it is the same attack or not.
