Desert Skull has Green Skull's shape, being entirely composed of red and yellow sand.
Powers and Abilities
Desert Skull has harenakinesis, able to manipulate sand. He can control his sand with his ultrasonic whistle, allowing him shapeshifting, regeneration and sand malleability, able to form weapons. He can form the slits to use the whistle on any part of his body, or if his body is just sand on the ground.
He can harden his body to deliver hard blows.
He can only control his sand with his whistle, so if sound is canceled out, he is left powerless.
His body has a finite amount of sand, so to morph his body or to stretch his limbs, it takes sand from other parts of his body.
His body is completely composed of sand, and if he's struck, his entire body breaks apart. This can be countered by using the whistle to recall the sand or to harden his body.
