- Olivia Pierce

Olivia Pierce is a character in Doom responsible for the invasion from Hell who functions as the main antagonist most of the story. She is first seen in a hologram recording examining the Doom Slayer's containment box, and is heard over the intercom of the Mars base in the opening stages of the game. She can also be seen on the monitor talking to the Marine.

Alongside with Samuel Hayden, she was responsible for working with Hell to advance human civilization within the UAC. She made a "deal with the devil" and gave Hell cybernetic enhancements for the demons there. However, she is unable to control the great power and tries to bring their world to this one. She is shown escaping through one of the hell portals with an argent energy tube.

By the time you meet her at The Well, she is shown severely weakened. She realizes Hell has deceived and betrayed her and mutters her last words to the Doomguy, "They promised me so much."The demonic forces of hell then strike her with a crimson lightning bolt, knocking her out and transforming her into the Spiderdemon.
