Official Canonical Drawings of Yomi Yomi no Mi & Kage Kage no Mi released.

One Piece focuses around the concept of mystical fruits that give their consumer superhuman powers broadly divided into three categories: Zoan, Paramecia and Logia. These fruits, called Devil Fruits or Akuma no mi are spread sparsely in the 4 quadrants of the world, however, are found abundantly in the Grand Line. The protagonist, Monkey D. Luffy, was the first character introduced to have a devil fruit ability, as he ate the Gomu Gomu no Mi (Rubber Rubber Fruit) which gave his body the base abilities of rubber. 

Recently, a One Piece enthusiast, @newworldartur tweeted out canonical looks at two major fruits introduced earlier in the series: Yomi Yomi no Mi and Kage Kage no Mi.

The Yomi Yomi no Mi (Revive Revive Fruit) was eaten by Brook long before the events of the current storyline and after his death, the fruit gave his soul the power to return back to the mortal world and gave life back to his skeletal body. Currently, the fruit gives Brooks the power to interact with and subdue soul, as well as, leave his own body and roam around as a ghost. The fruit aptly resembles a skull with the 4 knobs protruding from its lower half.

The Kage Kage no Mi (Shadow Shadow Fruit) was eaten by Gekko Moria, the main antagonist for the Thriller Bark arc. The fruit gave him the power to take away the shadows of anything that casts one by snipping them off with hilariously huge scissors. He can also give life to inanimate vessels using these shadows, essentially giving those vessels the powers held by the shadow. In addition to this, anyone without a shadow is disintegrated by direct sunlight.

About One Piece:

The man who had acquired everything in this world, the Pirate King, is Gol D. Roger. The final words he said at the execution tower were “My treasures? If you want it, I’ll let you have it. Look for it; I left all of it at that place.” These words sent many to the seas, chasing their dreams, headed toward the Grand Line, in search of One Piece. Thus began a new age! Seeking to be the greatest pirate in the world, young Monkey D. Luffy also heads toward the Grand Line in search of One Piece. With his diverse crew joining him along the way, consisting of a swordsman, marksman, navigator, cook, doctor, archaeologist, and cyborg-shipwright, this will be one memorable adventure.
