The gladiatorial games emerged in Kaon and Slaughter City, the low caste areas where workers sought a distraction from the drudgery of their lives. From the pits rose an unbeatable champion named Megatronus, who renamed himself Megatron. Megatron killed the gladiatorial bosses and took control of their establishments, merging it into what beacame an anti-caste movement that attracted followers in other cites.
