Devil fruit
The Chakku Chakku no Mi (チャックチャックの実, "Zipper Zipper Fruit") is a Paramecia Devil Fruit eaten by Trish. It allows the user to generate zippers on any surface she touches, which she can open or close at her leisure. For example, Trish can hit a wall, unzip it to create an opening and go through it, then close the zipper.
Trish can even create zippers that cut through the entirety of objects, allowing her to dismantle them. With this ability, she can separate enemies into multiple pieces and even perform a cutting attack by detaching something and then cancelling the zipper.
Inversely, Trish is free to attach several things together with her zippers. Such as reattaching a cut off limb or sticking body parts to others stronger in battle. However Attached limbs that are not one's own, are not affected by their temporary owner's devil fruits, but can still be affected by their weakness.
Because the zippers can be remotely opened and closed, Trish can take advantage of the zipping itself. She can create long zippers over surfaces and control the zipping to rapidly reposition herself if she holds the zipper's handle, for instance to move down an elevator shaft using the zipper to slow down her descent. Moreover, nearly cutting an object in two then rapidly closing the zipper from a distance creates a makeshift jawed trap.
However this devil fruit can only be used on solid objects and cannot be used on any liquid or air. Other than that, it suffers from standard devil fruit weaknesses.
