D an G

D&G is a major enemy from Part VI: Stone Ocean. He was an assassin hired by Enrico Pucci.

Story
In the past, D&G was a police officer who believed in Nostradamus' prophecy of the end coming in the year 2000. Because of this, he went around shooting several people at the start of the new millennium. Once the panic died down he was quickly arrested and placed upon Green Dolphin Prison, its unknown if he was given his stand by Pucci or developed it.

D&G was one of the four stand users assigned to kill Jolyne in the maximum-security facilities along with Kenzo. However, due to the automatic nature of his stand, he only was staying alive while his Stand fights with Jolyne and Annasui. He finally was discovered and killed by F.F.
