She could be a meta human and an Amazon of the Bana Migdall Tribe.
If they do intend to keep the Bana Amazon angle with Grace, it would be nice if they actually explored that and did some stuff with it.
As it currently stands in the canon, the short arc in Lobdells 'Red Hood and the Outlaws' and Orlandos run on Wonder Woman are the sum of world building for the group, and neither one touches on how Grace could be connected to the Bana.
Artemis hasn't that I can recall but Grace and Diana had their own special shortly after Amazons Attack that was supposed to add clarity to her story but didn't really.

I'd make Grace the result of Bana-Mighdall technology in their effort for their own Wonder Woman after the failure of one too many Shim-tars.
Not a follow up but Grace will also be appearing in The Other History of the DC Universe which focuses on Anissa Pierce.
I doubt Grace will get to much of a focus, but ive been enjoying the series quite alot so far.
Did anyone read the issue with Grace meeting Black Lightning? I always liked Grace and I'm shocked that it took this long for her to be brought into comics. I would love for her to appear regularly again somewhere. I always felt she would have been perfect for Red Hood and the Outlaws, but it seems Artemis beat her to the punch.
We are the Dora Milaje. We are the daughters of the 18 tribes of Wakanda. We are the teeth of the Panther God. Out of 10,000 years of sweat and bloodshed and battle are we born. We are the women of this ancient land. Deadliest of the species. And our time has come!
"It's fun and it's cool, so that's all that matters. It's what comics are for, Duh."
Words to live by.
