Inu Inu no Mi, Model: Black Shuck

The Inu Inu no Mi, Model: Wolf (イヌイヌの実 モデル：黒さや) is a -type that allows its user to transform into a Black Shuck hybrid and a full Black Shuck at will. "Inu" is Japanese for "dog", and a Black Shuck is a Large Black Dog so they are in the same family as dogs. It was eaten by Raiden's Sword Shigure.

Strengths and Weaknesses
The fruit's major strength, as demonstrated by Shigure, is that its user gains more physical strength in their hybrid and full Black Shuck forms, equivalent to that of a real Black Shuck and more. The User can also Travel Through Shadows as well as hide in them.

The fruit so far does not seem to have any specific weaknesses outside the standard Devil Fruit weaknesses.
