Zaria is bi-racial (black/white), and so voice actors who are people of colour will be prioritised.

Zaria (ZA-ree-uh) is a prodigious soldier. As a young woman in an army of men, she has had to work twice as hard as any of them for even half the recognition. She is driven by dreams of success. Her mother, Pandora, is the right-hand of The Tyrant (the leader of the army), and so there are high expectations for Zaria to live up to. Despite her lineage, she has been offered no easy breaks. If anything, it has only made her life harder. She was Marik's protege, and now, she is a member of The Obsidian; the elite soldiers. As such, she does not believe in going easy on others and she does not take Marik's treachery lightly.

I imagine Zaria with a mid-to-high range voice. Authoritative, commanding, and driven. 

In season 1, Zaria is a secondary antagonist, but she will have a more significant role in future seasons.
