Nibai Nibai no Mi

Introduction
The Nibai Nibai no Mi, or known as the Twofold Twofold Fruit. It is a devil fruit that doubles the force of a attack each time it lands. If a person punches you the first time it does normal damage. If a person punches you a second time it does two times the damage it did before. If a person punches you a third time it does two times the damage that was caused the second time you were hit. If they punch you a forth time it does two times the amount of damage done the third time.

Usage
When the power is active a golden aura appears around the user. This aura grows with each sucessful hit and only appears after the very first punch.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.

The power up count goes back to zero if the user goes unconscious. The same happens if the user shuts off thier power.
