Atriox is practically the face of the Brutes for people, just like how the Arbiter is basically the face of the Elites. A character that you immediately associate these species with. I'm hoping that great Brute characters like these guys can get more people interested in the Brute lore and that it warrants more species development and expansion.

Atriox isn't really the face of the Brutes when he's an unconventional Brute himself with his high intelligence being anomaly of his kind.

"That was the genesis of that character. What if one Brute was not only stronger than the others, but also incredibly intelligent. Atriox is, is something the Universe hasn't seen before."

His faction are also mercenary raiders who attack settlements on Doisac for wealth and power. They're cooler with their unique identity,

A proper Brute government is better represented with an official leader such as Lydus who does actual government stuff like diplomacy.
