Guro Guro no Mi

Guro Guro no Mi (グログロの実 Glow Glow Fruit) is a Paramecia type Devil Fruit that allows the consumer to create and control various colored lights called "Glows", making them a Glowing Human (グローイング人間 Gurooingu Ningen). Each Glow has a different effect that completely depends on the Glows respective color.

Strengths and Weakness
The Guro Guro no Mi is a very unique Devil Fruit, unlike most other Fruits it produces multiple abilities rather than a singular supernatural power. The Fruit grants its consumer to the ability to create different "Glows"; which are bright colored lights that produce different effects depending on it's color, with different effects with each varying color.

For example a blue-colored Glow freezes anything it comes into contact with, while a red-colored Glow would set any surface instantly on fire.These glows are normally produced from the palm of the user's hand then physically expanded or applied to a surface in order to use utilize each ability.

Usage
The powers of the fruit have been used by Romeo mainly for combat and pressing situations. He generates different colored glows to fit the situation. For example, Romeo constantly uses his Blue colored glow to freeze water since he cannot swim, but also uses his entire arsenal of glows during a fight.

The mastery of this fruit appears to be impossible or at least incredibly difficult simply because of the vast amount of glows that can be created. After initially eating the fruit, Romeo was only able to produce a single glow, but after training or intense battle Romeo would unlock a new glow with a different power. The fruit's powers appear to be connected with Romeo's emotions, as he unlocks a new glow in pressing situations when both danger and emotions are high. Also, when Romeo becomes enraged he enters a "Rainbow" form that allows him to command multiple glows.

Techniques

 * Violet Violence (バ暴力, Bouryoku): Romeo's signature glow, he produces a purple-colored glow that is able to shapeshift into physical mass. Romeo often shapes this glow into giant fists or objects used to crush his targets. As the glow expands it's weight becomes proportional, so the bigger the shape the stronger the attack.
 * Violent Violet Fist (暴力, Boryukukina): Romeo prepares this technique by compressing the glow mass around his fist before quickly releasing it, causing it to expand into a gigantic punch that crushes virtually anything in its path.
 * Blue Blizzard (青いいブド, Aoi Burizado): Romeo creates a Blue colored glow that freezes anything it contacts. The glow cannot be expanded so Romeo must physically touch something in order for it to freeze. After freezing a surface, Romeo can also create large blocks of ice and even shape them to any form that he desires.
 * Violent Blues (暴力ブ, Boryuburu): By fusing the purple and blue-colored glows, Romeo creates a blue-violet glow capable not only instantaneous freezing but expansion as well. This enables Romeo to freeze his target at long range.
 * Crimson Combustion (火深紅, Nenshou): Romeo creates a Red-colored glow that instantaneously combusts anything it contacts. Using this red glow also allows Romeo to command flames already created this technique, and heat a surface without creating a flame.
 * Green Gravel (緑利, Midorino): Romeo creates a green-colored glow that allows him to manipulate products of the earth such as plants and minerals. By touching the surface of the ground (ground must be natural or made of a stone based material) Romeo can freely move and manipulate rocks and plants, able to telekinetically force them to break, levitate and move at high speed. Any surface touched by the glow also enables Romeo to sense the presence of any living creature in the area as long as their weight is being applied to a part of that surface.
