The Contenders: Human vs Shapeshifting Entity
When: Fringe: "Momentum Deferred" Season 2 Episode 4
The Battle: The Shape Changer was an entity of unknown origin who could take the form of any human it killed. Dunham and the Fringe team came up across the Shape Changer multiple times, but in their last encounter the creature was wearing the face of Olivia’s best friend, FBI Agent Charlie Francis. The Shape Changer (as Charlie) lured Olivia into a trap, where he proceeds to give her the beating of a lifetime. While it was distracted, Dunham is able to retrieve her sidearm and shoot the Shape Changer square in the forehead.
Olivia is forced to shoot the creature not only while it looks like a close friend, but also never really knowing the last time she actually saw the real Charlie Francis. Messed up.
Winner: Olivia Dunham
