The Alliance was composed of Zygons, Judoon, Hath, Vigil, Sontarans, Silurians and Ice Warriors. After the Hyperions were defeated, Rassilon and the Alliance of Races embarked on another purge of races that were a threat to universal harmony.
One such enemy was Count D'if of the Cybock Imperium. Rassilon challenged D'if to a game of Rassilon's roulette using the Time-Gun of Rassilon. D'if lost and he was wiped from existence. (COMIC: Gangland)
