The devil fruit itself is like a lemon. A yellow with purple clockwise swirls. It's twice the size of a normal lemon though.  Once the skin is peeled of the clear colorless fruit is shown. The peel is edible just like most devil fruits.


The consumer of the Katai Katai no Mi is able to stiffen his/her or someone else's body partialy or completely. This fruit allows you to apprehend nearly anyone. Though some people with strong haki could break their stiffness.

For the user to stiffen someone else the user has to touch him/her. The devil fruit only seems to work on organisms. The stiffness is gona when the user cancels it or the timelimit runsout. The time limit on a stiffened one is 3 hours.

  • Has standard DF weaknessess. 
  • Does not work on logias when they are in their elemental form.
