The Straxus Brigade were named after Megatron's teacher, and father figure, High Governor Straxus of the Grand High Council of the City State of Kaon. Or, as he would become, Supreme Overlord. The Brigade are formed of the biggest, toughest 'cons there are for missions where absolutely no stealth is required, but incredibly thick armour and lots of firepower is. The brigade took out Epsilon Supreme at the Seige of Iacon. They destroyed the Omega Sentinel factory Autobot Outpost Omega 1. And they beat the Wreckers at Praxus-9.
