Dr. Mary Hiller is a scientist working with Dr. Martin Landry on the Portage Initiative. When Zarkov was asking too many questions following Lawrence Gordon's disappearance 13 years ago, Hiller had Zarkov committed.
Hiller moved to a private lab outside Baltimore three years ago. She's been married for six years to a litigator. She has a son from a previous marriage.
A Patriot disguised as Lawrence Gordon drains Hiller's brain with the Mind tap in Template:104 and leaves her for dead.
In the episode Template:119, she appears as a hologram to Dr. Zarkov in one of Rankol's labs.
