Jonathan Joestar/Abilities and Powers

Athletic Ability
Jonathan had lived a rough past as the son of an aristocrat, and was known in his childhood to have been at least a competent boxer. In his college life, he is shown to have played Rugby alongside Dio Brando, and was revered as one of the two stars of Hugh Hudson Academy.

Even prior to learning the ripple, Jonathan was shown to have been able to hold his own against three thugs, Speedwagon among them with his sheer might and willpower. He was also shown to have been able to wield various weaponry held by the suits of armor in the Joestar mansion, as well as perform incredible feats of strength, such as jumping from the hilt of a sword and hoisting himself up to the second floor with an arm inhibited by a spear pierced into his pectorals, even doing a flip over the guardrails as he did so.

Ripple
Jonathan has an arsenal of ancient martial art techniques, most inherited from Will A. Zeppeli and involving Ripple, at his disposal. Some are his original creation, each ending with "Overdrive".

Attacks

 * Zoom Punch (ズームパンチ): Jonathan launches his fist forward and strikes his opponent. First used by Zeppeli, the attack involves a ripple breathing technique that dislocates and stretches the joints to extend the arm and give it greater reach while also using the same ripple to dull the pain caused by the move. Due to the increased length, the strike immediately reaches the opponent's face first, which from that perspective seems "zoomed in."


 * Sendo Ripple Overdrive (仙道波紋): Jonathan charges a ripple wave through his arm and releases it into a solid object, such as a wall or partition. The ripple can travel through and reach anything on the other side, and anything hit by the ripple is sent flying in a spiral. If the enemy is an Undead, the ripple will enter their bloodstream and destroy them from the inside.


 * Scarlet Overdrive: Charging the ripple into one hand, Jonathan can create a ripple of flame. He is able to transfer over this flame to another part of his body, and anything that touches that body part has a chance of catching fire.


 * Underwater Turquoise Blue Overdrive (水中のための): Appropriately the strongest place to use the ripple, Jonathan can release high powered tempests while underwater with enough force to blast enemies away. In most cases, a good portion of the water is propelled outward as well, draining something like a lake to waist-high depth.


 * Overdrive Barrage (連打): When Jonathan jabs fast enough consecutively, he can release multiple Overdrives at once.


 * Metal Silver Overdrive: Essentially the same as a Sendo Ripple Overdrive, but with the ability of transferring through metal.
 * Life Magnetism Overdrive (生命磁気への): With the aid of Zeppeli, Jonathan can draw all the leaves in the immediate area and magnetize them together to form one giant leaf, which was used as an impromptu-hang glider. This move can be applied to most plants, and has the ability to revive them passively as well - as when Jonathan touched a dead tree branch with his newly Ripple-healed arm and restored its wilted flowers.
 * Sunlight Yellow Overdrive (Yamabuki-iro no Hamon Shissō) Sanraito Ierō Ōbādoraibu (！！): His final and most memorable attack, first marked by Jonathan's words: "My heart resonates! The heat's enough to burn! The beat of my blood is razor-sharp!!" (ふるえるぞハート！燃えつきるほどヒート！！刻むぞ血液のビート！). It is a devastating and extremely rapid flurry of Ripple-infused punches with power comparable to the sun itself and has the ability to completely obliterate the Undead.

Alongside the attacks, the ripple has various other uses in combat. A skilled Ripple user such as Jonathan has the ability to walk on water, strengthen objects and increase their potency, increase jumping height, and much more.

Healing
One of the main conveniences of the ripple is the ability to heal the body to an extent. During his battle with Doobie, Jonathan was able to eject poison out of his bloodstream via Ripple transfusion. During his battle with Tarkus, he was also able to heal his broken neck after receiving the Supreme Pass Overdrive from Zeppeli.

Weapons

 * Luck and Pluck (と): After his defeat, Bruford gave Jonathan his sword, which played a major role in the final battle against Dio, where Jonathan was able to counter Dio's freezing ability by infusing the sword with Ripple, in order to avoid direct contact with Dio's body. '''

Stand
Manga Debut : Chapter 122, The Thing on the Plane

Along with the The World, it was stated that Dio's semi-precognitive abilities that seemed to have resulted from a Hermit Purple-like stand were due to a stand power that awoke in Jonathan's body. Similar to Hermit Purple, it can produce a psychic photograph by smashing a camera, which Dio used to track the Joestars and their friends's current location to send Stand Users after them.
 * According to the JoJo novel, Over Heaven, the stand shares the same name with Hermit Purple, but with the novel, Jorge Joestar, it's name is The Passion
