Fictional team history

The 10
A recent story in Superman #665 shows that during Superman's early years in Metropolis, there was a smaller organization called the 10, with ties to Intergang. According to Black Lightning: Year One #4 (April 2009), they have no ties to the 100 but may have ties to the 1,000.

The 100
The 100, formerly known as El Ciento (the one hundred), was founded by 71 men and women from all over Europe who came together in Aragon, Spain in the year 1462, and named themselves El Ciento in order to honor their 29 dead allies. The surviving members of El Ciento combined various scientific, arcane and alchemical methods of life extension in order to render themselves immortal. At a later point in time, they were driven out of Aragon by the Spanish Inquisition, but by then they had granted themselves vastly extended lifespans. They later discovered that the only way they could stay alive was to own the land they lived on and to feed off the despair and negative emotions of the human tenants on their lands; they also learned how to become immaterial and possess human bodies. Though most members of El Ciento feed off human suffering, some few have been able to survive by feeding on positive emotions. The immortal known as Ra's al Ghul considers El Ciento to be a threat to his plans.

A member of El Ciento later established himself in Metropolis's Southside, an area which would later be known as Suicide Slum. The 100 held a firm grip on the city's criminal underworld for years, indulging in crimes such as drug trafficking and racketeering. They later seem to have spread across the country with branches operating in other cities. They have also made enemies of many heroes, including Rose and Thorn (whose father they murdered), Halo (whom they murdered as well as her parents), and Superman himself. As the 100, they fought foes like Black Lightning at the behest of the Metropolis section leader Tobias Whale.

The 1,000
The Director of the 1,000 was a U.S. senator named Henry Ballard who shepherded the organization's new direction and goals. Under the Director, the 100 changed its name to the 1,000, where it is attempting to expand their reach to even the Oval Office with Henry Ballard as the presidential candidate. This plan, however, was thwarted and the 1,000 became the 100 again upon retreating into the shadows. As the 1,000 they fought Booster Gold.
