Kage Kage no Mi

Kage Kage no Mi (シャドウシャドウフルーツ Shadow Shadow Fruit) is a paramecia type Devil Fruit that gives the user the ability to manifest and control shadows, as a tangible and physical form, making the user a Ruler of Shadows (影の支配者 Kage no Shihaisha).

Strengths and Weaknesses
The first and foremost strength of the fruit, as demonstrated by Kyrios, is that its user is able to manifest shadows into a physical and tangible form. These shadows allow for a high level of adaptability; the shadows are able to be released in free form, as condensed, or even molded into the shape of a weapon, taking on the properties of said chosen shape. The user is also able to fade themselves into shadows to move swiftly, dodging efficiently and making surprise attacks

All shadows follow the soul of its owner's movements, and cannot be changed from birth to death; this Devil Fruit allows the user to change that absolute rule. By connecting their own shadow to their targets, the user can then control their targets movements as long as their shadows remain attached. Kyrios makes use of this ability for assassinations, since his targets are immobilized. A

The fruit also grants it's consumer the ability to "steal light", in an area, which can vary from cutting out the lights in a room, to blocking out the sun. By stealing the light away from an area, that area is plunged into darkness, lowering visability to zero.
