Masonius is one of the gladiators who fights in the arena for the honor of executing Crixus, Oenomaus, and Rhaskos.


Masonius has dark skin and a low monotone-voice. He fights in the style of Hoplomachus, using a spear, round shield, and short sword and wears a set of armor that is appropriate for a hoplomachus.


Masonius, like many gladiators, revels in the glory of fighting in the arena. He has fierce skill and a dangerous fighting style. He also holds honor in high regard, expressing having had long desire to fight beside Gannicus, whom he considers to be the best champion to ever enter the arena.


Masonius is pitted against Strabo in a match. It is a close fight, but Masonius is the victor, killing Strabo with a sword thrust to the back of his neck.

Having thus earned his place in the primus of the games, Masonius joins Gannicus and his fellow gladiator executioners in battle against Crixus, Rhaskos, and (later) Spartacus.

He expresses great honor of being able to fight alongside Gannicus upon the sands.

He is later killed by Spartacus during combat, with a trident of another fallen gladiator.
