Gaisho Gaisho no Mi

Introduction
A Paramecia type devil fruit that gradually augments the user's strength, speed, agility, durablility, etc. in relation to their perception of danger. Essentially the longer the user is fighting, the stronger they get. But the user gradually reverts to normal after he/she stops fighting.

Usage
The user had to be feeling threatened, scared, in danger, or in a fight to start the process. The process ends when the user is no longer in those situations, and they begin reverting. Also ends when the usser is unconcious or dead.

Strengths The longer a fight goes on, the harder it is to fight against.

The user also heals faster as time goes on.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.

The user is weakest at the start of a fight, and if the opponent knows this they can target the user at the beginning of a fight to get them out of the way.
