Before the times of Oenomaus, Gannicus, Crixus and Spartacus rising to fame, gladiators such as Magnetius and Dolor under the lanista Titus Batiatus (and his father, before him) had their own claim to fame as Champions of the House of Batiatus.
Magnetius was Titus' Champion, proclaimed by him to be one of the finest ever to come from his ludus. Magnetius' weapon of choice seems to be a single Gladius Hispaniensis, an older and longer type of Roman sword not traditionally used by gladiators. Magnetius wields the weapon two handed with deadly purpose and strikes with such force that his opponents often lose balance and even control over their own shields.
HadrianusEditHadrianus was a tall, lean man who wielded an axe inncy to use their former top gladiators as trainers. This was proven false by the Blu-ray release of Gods of the Arena, where the prequel doctore was revealed to be named Ulpius.
Acolytus fought with a sword and shield. He bore a faintly Greek appearance, due to his white beard and the shape of his helmet, and his name would suggest this origin too. His fighting technique, great strength and prowess as a Champion could also suggest Spartan heritage.
