Goe Goe no Mi

The Goe Goe no Mi is an anime-only Devil Fruit that allows user to create beams of sound by shouting. "Goe" is a variation of "koe," meaning "voice" in Japanese. Eaten by El Drago in the first movie.

Strengths and Weaknesses
The main (and only) strength of this fruit is that it allows the user to create powerful beams of sound that can destroy anything in its path. However, this sound wave seems to be reflect-able, as shown by Luffy.

This fruit doesn't seem to have any other weaknesses, aside from the standard Devil Fruit weaknesses.

Usage
As shown by El Drago, he mainly shouts at his targets to use the sound blasts to destroy them.

Trivia

 * This Devil Fruit power is very similar to the Mouth Energy Waves used by certain characters in the Dragon Ball series.
