Triumverate

The Triumverate was a group of three Decepticons ruling their capital city of Helex: Legonis, Octus and Seizer. Having grown tired of warfare, the Triumverate amused themselves by pitting Decepticon warriors against Autobot prisoners in gladiatorial combat. When Megatron came to shake his troops out of their complacent existence to act as warriors once again, the Triumvirate tried to destroy him- only to be assassinated by the disgruntled Ruckus, Crankcase and Windsweeper.
