A Gladiator's Worst Nightmare (Rear)
the most formidable opponent in all of Ancient Rome: the red Rock Em Sock Em Robot! With its head being its only vulnerable spot, and having extensive range, it only takes one good uppercut from the red bot to knock out a gladiator. Just seeing the robot's last victim sends two other gladiators running!
