Why is he swinging a spear? Is he from spear infantry? Otherwise he should be using a gladius.

Why is his armor gold instead of a steel gray if it’s roman themed? And if it’s supposed to be an elite group or something but still based off Romans, why are the secondary colors red instead of purple? Purple is the color of royalty in ancient Rome. Also, if it’s supposed to be based on Roman Legionaries, why is he in what looks to be full chain mail? And why does he look more like a Spartan than a Roman?

I see that you’re getting Mars mixed up with Ares. You see, Mars & Ares may be the same person, but roman mythology Mars & Greek mythology Ares are two very different gods. Mars, in Roman Mythology, is actually very level-headed and was seen as a virtuous figure by the Romans. Furthermore, the Romans believed that Romulus and Remus were actually children of Mars, as they believed Mars raped their mother. This, and the fact that they viewed Mars as the defender of both Rome and the Roman way of life, is why the Romans called themselves “The sons of Mars.”

All of this is to say that, for a Roman theme, Mars is very much the wrong god to use as an enemy of the players if you’re going to portray the players as Romans.

Honestly, looking at this, it seems more like you intended all of this to be Greek themed, with the player skin being a Spartan, and then you remembered the Spiteful Scutum is in the game so you hastily tried to make it Roman instead of Spartan & Greek without doing any research on the major differences between the two.
