ZZ

ZZ (ズィー・ズィー) is an enemy Stand user from Part III: Stardust Crusaders hired by Dio to kill the Joestar group.

Appearance/Personality
ZZ initially seems like an intimidating character due to his large arms and his loud imposing speech. Arrogant and stubborn, ZZ thinks of himself as superior to his enemies and often compares then with bugs and insects in general. He is described as a angry, stupid and strong man who can't even solve a rubik's cube, heavily relying on brute force alone. He, however, is rather experienced in battle, maintaining his calm and not being impetuous. Even though he's rather cunning, managing to trick the Joestar group multiple times, his arrogance is his weakness, as he eventually told his enemies what he was planning to do and the secret behind his technique.

When his car is destroyed he proves to be a coward who only pretended to be strong, running away without his stand to protect him. To the group's surprise, ZZ is revealed to have large and muscular arms, while  the rest of his body is relatively skinny.

Stardust Crusaders
ZZ is first seen driving his car slowly along the road to Pakistan. Jean Pierre Polnareff, driving the group's jeep, rudely passes the car and kicks up some rocks with the jeep on purpose to taunt the slow driver, but the group soon realize that they are been followed by his car. ZZ then directs his car to pass and begins to drive slowly again, and when he directs them to pass, directs them into the way of an oncoming truck, which Star Platinum saves them from by stopping the truck and pushing the jeep away from it in midair. ZZ is then seen switching the direction of the sign to Pakistan in order to corner them at a closed road later.

The group stops for some rest and spots ZZ's car again, which they then give chase. Soon, Noriaki Kakyoin realizes that the group is headed the wrong way and Polnareff stops the jeep abruptly at the end of a closed road. ZZ then appears from behind and pushes the group's jeep off the cliff. Kakyoin's Hierophant Green, however, manages to hook the jeep's harness onto ZZ's car, stopping their fall. Jotaro Kujo then directs Star Platinum to tug on the rope, forcing ZZ's car to back up, and then punches the car, causing ZZ to fall down the cliff.

However, ZZ is revealed to have survived and reveals to the group that he was using a stand, called Wheel of Fortune and his knowledge of Joseph Joestar's name. He then bursts out of the ground in his car, smashes the jeep, and transforms his car into a more aggressive style. He charges at the group and fires gasoline bullets at them through his car, while effortlessly squeezing between crevices and causing spikes to grow out of the wheels to enable it to climb the cliff. After climbing the cliff, ZZ reveals that the gasoline bullets were meant to set them on fire and sets off a spark that sets Jotaro on fire. ZZ proclaims his victory and shouts that he "ended Part 3 early", only to be met with Jotaro's question over who will "replace [him] as the main character" and reveals that he dug a tunnel with Star Platinum and that the only thing that was burned was his jacket. Now defenseless on his side, ZZ is left unable to defend himself as he is propelled out of his own car and plowed into the ground with Star Platinum's barrage of punches. ZZ is then subject to the ridicule of the group as they realize that the rest of his body is skinny and the strong-looking car he drove earlier turned into a smaller car. He is then chained to a rock with a sign nearby that states that he is training and would not like to be disturbed and robbed of his passport and car, left behind to starve to death.

Stand
Wheel of Fortune represents the Tarot Card of the same name. While the Joestar group runs from ZZ, he proclaims that all the roads to their safety have been destroyed by his stand, including the road for a future. The Wheel of Future card holds the meaning of twists and unexpected changes in life, all due to superior forces (like destiny or fate). ZZ's statements shows how he believes that its already decided he will change their lives, just like a force superior to their own free will. His attack causes a rather sudden change of their views of the trip: keeping a ordinary person like the Runaway Girl with them can be really dangerous for everyone. Even though they wanted to get rid of her earlier, the Joestar group only makes sure she won't follow them after ZZ's attack. In order to reply to ZZ', Jotaro tells him that roads are made by one's self, not pre-determined by fate or destiny.

JoJo's Bizarre Adventure: Heritage for the Future

 * In the "Deadly Traffic" chapter of the Story Mode, the Joestar group encounters him on their way to Pakistan from India. His part in the story plays out much like the manga, though the player must go through several quick time events to defeat him.

Trivia

 * ZZ is one of the few characters to break the fourth wall, claiming he ended Part III early after apparently defeating Jotaro. He is then questioned by Jotaro about who is going to replace him as the main character.
 * According to JOJOVELLER, his body is shaped this way only to make a joke.
