Joseph Joestar/Abilities and Powers

Ripple
Joseph inherited the ability of the Ripple from his grandfather Jonathan. In addition, he uses techniques commonly present in stage magic to confuse his foes. After his Ripple training, he frequently combines his Ripple with other objects to perform complex and creative attacks. Later in Part III, he shows that he is able to pass the Ripple through his stand.

American Crackers
In order to come up with a special attack, Jojo invented a fighting style that involved infusing the ripple into a pair of Normal American Crackers. When infused, the crackers become a lethal weapon, as the user is able to rip through an opponent's skin with them, and from there the ripple can enter the body, thus inflicting massive damage. Because of their shape and aerodynamic design, someone who is trained in their use is able to easily manuever them around their body, even having the ability to make them seem to disapper by hiding them behind their back.
 * Ripple Cracker Volley: Joseph chucks the crackers into his opponent's direction. This can be done a number of ways, but to produce the best effect, he can hide them behind his back. From there, he can slingshot them from his back at the enemy from all directions.
 * Cracker Boomerang: Joseph chucks both pairs of crackers into a beam or pillar behind the opponent. This is in order to fool them into assuming he missed them when using Ripple Cracker Volley. One is thrown into the partition, causing one side of it to be lodged in place. The other side grabs onto the 2nd pair of crackers, and essentially flings them back towards the opponent from behind, much like a bommerang works.

Stand


Hermit Purple manifests itself as a tangle of thorny vines, which Joseph can wield as both weapon and defense. Joseph develops the stand after Dio pierces Jonathan's body with the Arrow, upon which it responded to Dio and Enya awakening The World.

The Hermit card primarily gives a meaning of solitude, introspective, or soul-searching, which could symbolize Joseph's lifelong journey. It also carries a more direct meaning of teaching or advising, which is Joseph's main role in Part 3.
