Olivia Pierce

"My sisters and brothers, be thankful. You will be the first. You will have a seat alongside them as I will in what will become the new world they create for us. Starting now."

- Olivia Pierce

Olivia Pierce is the main antagonist of Doom (2016). She is a scientist who is working with Hell to bring a world for mankind. She is heard talking on the intercom at the Mars base during one of the opening stages of the game, and she is also seen on the monitor talking to the Doomguy.

Trivia
She is very similar to Malcom Betruger, the main villain of Doom 3, as both villains are mad scientists who colluded with Hell.
