Buki Buki no Mi

The Buki Buki no Mi is a Paramecia type Devil Fruit that gives the user the ability to change their body parts into weapons, which lets the user become a Full-body Weapon Human (全身武器人間). It was eaten by Baby 5.

Strengths and Weaknesses
The Buki Buki no Mi gives the user the ability to change their arms into any kind of weapon. So far, Baby 5 has been able to change her arm into a cannon, an axe, and a scythe, as well as transforming her finger into a gun. It is unknown if this power extends to the rest of her body or if it is limited to her arms.

This fruit doesn't seem to have a weakness, other than the standard devil fruit powers.

Usage
Baby 5 predictably uses this fruit for assassination and combat in both long-and close range.
