Moria uses this "feature" to make the giant zombie, Oars, stretch his limbs just like Luffy. Normally, Oars is a giant who cannot stretch, but Moria extends Oars' shadow, which forces Oars' physical body to elongate to match the shadow's shape.
Moria systematically takes down several Straw Hats, including Nico Robin, Sanji, and Chopper.
Moria also uses a useful defensive feature of his Shadow-Shadow Fruit powers to instantly switch places with his shadow, Doppelman , allowing him to evade attacks—such as when he rendered Nico Robin's Clutch attack useless by swapping locations with his shadow. Episode Overview
