Though it always seem that when pierced again by an arrow the user gains a new ability. It should be noted, however, that in the only known example of this, the Arrow has had to move by itself and pierce the Stand user willingly. When someone who is already a Stand user is pierced by the Arrow, such as the case with Yoshikage Kira, the Stand in question gains a new ability. On the other hand, the Arrows normally only seek out (and pierce) those who can handle the strain to begin with. However, if the target lacks sufficient spiritual strength, they will die if the wound is fatal. This process has been described as being similar to natural selection W, the evolutionary process in which some creatures better adapt to their circumstances than others and thus survive more easily. However, a small number of people possess an abstract trait that allows them to survive, and as if to reward this trait, the individual's Stand is manifested. The virus is a merciless one, with most people who contract it dying. The reason the Arrows can awaken Stand abilities is because the meteorite the Arrows were made from was host to an alien virus. When a living creature is pierced by one of the Arrows, it will catalyze and awaken the individual’s dormant Stand. Over time, the six Arrows were eventually distributed between various people, among them were Keicho Nijimura, Yoshihiro Kira, and Jean Pierre Polnareff. The Arrowheads were eventually stolen by Diavolo, who later sold five of them to Enya the Hag, believing he only needed one. These Arrowheads had since been lost to time until 1986, when an Egyptian ruins investigation team, among whom was a young Diavolo, uncovered six of the arrowheads from underneath the Egyptian desert. The Arrows allowed the wielder to unlock Stand abilities in those who had the potential to awaken one, essentially acting as the aforementioned trigger. Several hundred years before the discovery of the virus, a man who wished to acquire the power of the gods took the rocks and fashioned them into Arrowheads. Akin to the theory of evolution, it was discovered that certain people possessed a quality that would enable them to survive when exposed to the virus, as well as grant them supernatural abilities, known as Stands. Despite extensive research, government doctors were unable to determine the alien virus' purpose outside the total elimination of human life. In 1978, a mineral excavation team uncovered an unknown virus within the rocks of the surrounding area and determined that it had been lying dormant inside the meteorite that hit Earth long ago. It is theorized that the meteorite sought out Earth through the will of its many strong spirits, rather than striking the planet by chance. Surveyers discover virus from Meteorite craterĪpproximately 50,000 years ago, a meteorite crash-landed on Earth around an underpopulated region of what is now known as Cape York W, Greenland W. 4 Chain of events as described in Part 5.2.2 Arrow piercing Stand users or Stands.
