Doctor Octopus

Doctor Octopus – Olivia “Liv” Octavius Portrayed by Kate McKinnon

A brilliant inventor with a genius-level intellect and a sharp, offbeat sense of humor, Olivia Octavius revolutionized cybernetics with her creation of four mechanical, AI-assisted arms. But when corporate sabotage destroyed her research and reputation, she turned her brilliance toward building a new life on her own terms — one where her tech serves her agenda. Each arm is a weapon, a tool, and an extension of her will, making her as versatile as she is dangerous.

Kate McKinnon brings a disarming mix of eccentricity and menace, making this Doctor Octopus unpredictable in both speech and action. In the New MCU, her chaotic energy hides a calculating mind, turning every battle into a game where she’s already thought three moves ahead.
