Olivia Pierce

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

- Olivia Pierce

Olivia Pierce is a character in Doom (2016) who is responsible for the invasion from Hell and functions as the main antagonist for most of the story. She is first seen as a hologram recording examining the Doom Slayer's containment box, and is heard over the intercom in the Mars base during the opening stages of the game. She could also be seen on the monitor talking to the Doom Slayer.

History
Pierce is the head of biochemical research at the Argent Facility on Mars. A former protege of Samuel Hayden, she graduated with first class honors in biomechanical and genetic engineering in Strasbourg. After graduating, she made a fortune by becoming one of the founders of a global research company called NanoStruct Aerospace and Defense Systems. However, she eventually left the company after Hayden gave her an artifact from the Argent Fracture, which slowly corrupted her mind and led her to make the decision to join the Lazarus Project at UAC as its Head Director.

After a few months working in the Argent facility, she suffered from idiopathic scoliosis, causing her to be bound to a wheelchair. In order to regain her freedom of movement, she agreed to take an experimental augmentation surgery which involved grafting a titanium exoskeleton to her body to replace her damaged spinal function. Despite regaining her ability to walk, moving causes her a tremendous amount of pain due to a side effect of the procedure. However, she refuses to take painkillers, believing the medicine would cloud her mind.

Doom (2016)
Along with Samuel Hayden, she was responsible for studying Hell to solve the human energy crisis within the UAC. Ultimately, she made a deal with a unseen demon lord in Hell and gave cybernetic enhancements to the demons there, and ensured that the location of the Doom Marine's tomb remained a permanent secret. However, she was unable to control the great power she had gotten her hands on, nor stop the Doom Marine from reawakening, so she tried to bring the demon's world to this one. She was later shown escaping through one of the hell portals with an Argent energy tube.

By the time the Doom Marine meet her at The Well, she is shown bloody and severely weakened. She realizes Hell has deceived and betrayed her and mutters her last words to the Doom Slayer, "They promised me so much." The demonic forces of Hell then strike her with a crimson lightning bolt, transforming her into the Spiderdemon to fight the Doom Marine, which he defeats in a boss battle and glory kills with a BFG blast to the mouth.

Appearance
Olivia Pierce is a Caucasian English woman that appears to be aged somewhere between her late 40s to early 60s. She has white hair cut very short and wears a light gray exoskeleton. She appears sickly and almost emaciated, being very thin and and short of stature compared to the rest of the game's cast.

Near Samuel Hayden's office level in the UAC Mars base, there is a digital photo of her younger self hanging on the wall, where she has short blond hair and wears a typical scientist lab-coat and jewelry.
