Goe Goe no Mi

The Goe Goe no Mi is an anime-only Devil Fruit that allows the user to create beams of sound that look like energy beams by shouting. "Goe" is a variation of "koe" (声), meaning "voice" in Japanese. It was 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.

This fruit doesn't seem to have any other weaknesses, aside from the standard Devil Fruit weaknesses. However, this sound wave seems to be reflect-able, as shown by Monkey D. Luffy, who collected the sound wave blast with his rubbery powers and slingshot it back at El Drago.

Usage
As shown by El Drago, he mainly shouts at his targets to use the sound blasts to destroy them. Before El Drago fires a sound blast, he emits a yellow aura. The aura's intensity changes depending on the power of the blast.

Trivia

 * This Devil Fruit power is a reminiscence in appearance and effect to the Mouth Energy Waves used by certain characters in the Dragon Ball series.
 * The beams of sound resemble the Thousand Sunny's Gaon Cannon (a beam of compressed air) and the Pacifista's laser beams fired from their mouth (which is based on light instead of sound).
 * This fruit's power is similar to Scratchmen Apoo's power as they both use sound as a weapon.
