- "Lexine's right... Leon would flip if he saw this..."
- —Sam Caldwell
Leon was a CEC supervisor on Aegis VII.
Leon was Lexine Murdoch's supervisor and friend of Sam Caldwell, humorously described as "aways nuts" by Sam. A devout Unitologitst, he was one of the fifty colonists who joined the prayer group led by Deakin Abbott when the Marker 3A was discovered.
During the events of Chapter 1, when the Red Marker was removed from its pedestal and activated, Leon committed suicide with the rest of the group at the Union Square. His corpse was taken to the morgue and presumably reanimated as a Necromorph during Chapter 2.
