Kronos Family
The Kronos Family were an organised crime family active in Las Vegas, Nevada, from 1962 to 1963. They operated their own Cosmos Casino as a front for their activity. They systematically took over casinos and rackets from the Dragotta Family, which eventually led to a gang war.
The Kronos Family were made up of Agents of the Cybock Imperium, led by Kronos, who were living in secret on Earth after their species had been largely wiped out by Rassilon's Alliance of Races following the Hyperion War.
The Kronos Family were effectively erased when the Twelfth Doctor tricked Kronos into shooting himself with the Time-Gun of Rassilon, dissolving his own timeline and subsequently preventing him from leading his Cybock agents to Earth in the first place. (COMIC: Gangland)
