Originally known as the "Gangster Killer Bloods", the G-Shine Bloods gang was one of the first Blood sets to form on the east coast of the United States in Brooklyn, New York in 1993. In 1993 the New York State Chapter of the Latin Kings and the Netas were the 2 largest and most violent Latino Hispanic organizations on the streets and prisons of New York City. These organizations controlled the New York State prison systems and targeted the independent Black gangs with daily acts of Racist and Prejudice violence. The independent black gangs incarcerated in Rikers Island desperately needed a way to unite, so under the tutelage and guidance of O.G. Mack, convinced other black gang leaders to unite their gangs under one banner. This organization would later be known as the United Blood Nation (or UBN). Leonard "Deadeye" Mackenzie, who got his nickname for his cloudy right eye that appeared dead, was instrumental in helping O.G. Mack in forming the UBN and expanding its growth within Rikers Island. O.G. Deadeye was the leader of his own gang that was based in Brooklyn and upon meeting O.G. Mack he re branded his gang into the Gangster Killer Bloods. Over time, this gang spread through out the east coast, particularly in New Ark, New Jersey.
