Jonathan Joestar is the protagonist of the first part of JoJo's Bizarre Adventure. He is the son of George Joestar I and the grandfather of Joseph Joestar.


As an infant, his mother died in a carriage accident. That same accident indirectly brought Dio Brando into his life, because Dio's father unwittingly saved Jonathan's father while preparing to steal from the wrecked carriage. Twelve years later, Dario apparently died of illness and Dio went to the Joestars. Despite Jonathan trying to be friends with Dio, the latter would become his nemesis both as a childhood rival and as an undead enemy. At the young age of 12, when Dio came into his life, Jonathan met and fell in love with Erina Pendleton, but Dio shattered the relationship for a considerable amount of time through his evil ways, by kissing Erina and boasting about it. Learning of this Jonathan came home to confront Dio. Jonathan beats Dio in a fistfight, but a humiliated Dio decides to take revenge by killing his dog, Danny, Jonathan's only remaining companion and true friend.

Nonetheless, Jonathan is able to maintain his sanity and continues his studies in archaeology. Among his interests is research on a Mesoamerican stone mask that is part of the estate. Curiously, the mask sprouts spikes that pierce the wearer's skull and spray a black, foul-smelling liquid if human blood touches it. Finally, after eight years, Jonathan takes a stand against Dio when he discovers that Dio poisoned his own father with a substance that imitated illness, and intends to poison George in the same way to take over the family fortune. Jonathan then travels to Ogre Street in order to find an antidote, which he locates thanks to the help of his new comrade Robert E.O. Speedwagon. In a fateful encounter, Dio stabs George while wearing the mask (having learned that the mask was not a killing device, but a means to let the wearer transcend humanity, mortality and anything resembling moral restraint to become a mighty vampire).

After a battle in which the Joestar Mansion is burned down, Jonathan suffers horrible burns and is taken to the hospital, whereas Dio is able to escape unseen but also badly wounded. Robert E. O. Speedwagon finds out that the nurse taking care of Jonathan is actually Erina, who had gone to India after Dio disgraced her and ruined her relationship with Jonathan. However, Dio had apparently not extinguished her feelings for Jonathan. Shortly after being discharged from the hospital, Jonathan meets William Anthonio Zeppeli, who informs him of Dio's survival and begins to teach him the way of Hamon in order to defeat Dio.

Powers & Abilities

  • Hamon: An ancient way of martial arts based on self-controlled respiration. Hamon is based on using the energy of the sun's rays through breathing and empowering the body with "ripples" of solar energy. While it can be used to destroy vampires and zombies, it can also affect non-living things. An object, while charged with Hamon energy, will become more dangerous, and its user can perform several techniques that can combine with the warrior's own tactics, to allow for a very flexible fighting style. It can be used to deliver extremely powerful 'Overdrives' and other techniques.
    • Zoom Punch: Jonathan dislocates and launches his fist forward and strikes his opponent. The attack involves a Hamon 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 ache caused by the move.
    • Sendo Hamon Overdrive: Jonathan charges a Hamon 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 Hamon 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 high chance of catching fire.
    • Turquoise Blue Overdrive: Appropriately the strongest place to use the ripple, Jonathan can release high powered tempests while underwater with enough force to blast enemies away.
    • Overdrive Barrage: When Jonathan jabs fast enough consecutively, he can release multiple Overdrives at once.
    • Metal Silver Overdrive: Essentially the same as a Sendo Hamon Overdrive, but with the ability of transferring through metal. Often used in combination with Luck & Pluck.
    • Life Magnetism Overdrive: 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 Hamon-healed arm and restored its wilted flowers.
    • Sunlight Yellow Overdrive:  It is a devastating and extremely rapid flurry of Hamon-infused punches with power comparable to the sun itself and has the ability to completely obliterate the Undead.
  • Healing: Thanks to Hamon, Jonathan can heal minor wounds.


  • Luck & Pluck: A sword given to him by Black Knight Bruford after his defeat at the hands of Jonathan. He often uses it as a way to channel Hamon through his enemies without the need of touching them.
