I believe in honesty... especially now, in what will be your final moments in this world. All the rumors... the human sacrifices... the Hell portal... the demons... it's all true. 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.

Dr. Olivia Pierce, later known as the Spider Mastermind, is the overarching antagonist of the Doom reboot series.

She is the main antagonist and final boss of the 2016 reboot of Doom and the posthumous overarching antagonist of both its 2020 sequel Doom Eternal and its DLC expansion Doom Eternal: The Ancient Gods.

She is a corrupt UAC scientist that is responsible for the demonic invasion of Mars, seeking to bring the forces of Hell to Earth, making her the catalyst of most of the events of the Doom series as a whole.

She is voiced by Abby Craden.

What Makes Her Pure Evil?

  • After making a Faustinian Pact with the Hell Priest Deag Ranak, she performed satanic rituals to transform her fellow scientists into demons.
  • She released many of the demons she created onto the rest of the Argent Facility, either killing or zombifying her subordinate scientists.
  • She uses the Argent tower to open a portal to Hell, allowing for the rest of the demons to attack Mars and the rest of the galaxy, including Earth.
  • She sends a message to the rest of her co-scientists, announcing that they will suffer eternally in hell while she ascends to godhood.
