Mariah Romanova was one of Warlord's soldiers.
Mariah helped Warlord in his battle against Deimos. With her athletic skills and marksmanship, she took down several dino troopers.
She was present at Warlord's victory speech after the final defeat of Deimos.
The depicted subject bears the likeness of Mariah Romanova from the DC Comics; however, the DCAU character was never named on-screen, or otherwise. The title of this article is conjecture based on the character's likeness. Mariah Romanova was an archaeologist who met Travis Morgan during one of his trips back to the surface. She joined him and started a relationship with Machiste, though she loved Travis Morgan more. While it is unknown whether she is from the surface or a native of Skartaris in the DCAU, she is notably the only one other than Warlord to use modern weapons.
