Kronos (Gangland)

Kronos was the commander of a group of agents of the Cybock Imperium, and founder of the criminal Kronos Family in Las Vegas.

After leading his agents to Earth in 1962 and expanding their criminal empire over the space of one year, Kronos was challenged to a game of Rassilon's roulette by the Twelfth Doctor. Like the previous leader of the Cybock Imperium, Kronos lost, and his entire history was erased. (COMIC: Gangland)
