Gomu Gomu no Mi

The Gomu Gomu no Mi is a Paramecia-type Devil Fruit that gives the user's body the properties of rubber, making the user a Rubber Human. The fruit's major strength is that the user's body can stretch, bend, bounce, inflate, and twist like rubber, even when the user himself is nullified. The user can stretch and extend the reach of their attacks (up to 30 ft). This stretching also allows you to reach distant locations and pull yourself there. You can also use your stretched arms to launch yourself like a slingshot. Defensively,  being made of rubber, you are now immune to lightning and non-magical bludgeoning damage. You also don't take damage falling from heights. You have also been cursed with a permanent inability to swim.
