Overview
The exact function of the Waku Waku no Mi’s abilities is relatively unknown as Kujaku has yet to utilize the greater strength of the fruit.

Strengths

The user also seems to have the ability to enter their own planets and while in direct content with their created planet, the user is able to manipulate the planets function on a whim.

Weaknesses
