Rex Matheson

Rex Matheson was a CIA agent in the 21st century.

Biography
Matheson was talking with his colleague Esther Drummond on the phone when he was involved in a car crash, a pole from a nearby truck pierced his body. Matheson later awoke in a hospital and learnt that the pole should have killed him and began to look into Miracle Day, a phenomenon where no human on Earth could die.

Matheson's hunt for answers led him to Wales, where he extradited the surviving members of the Torchwood Institute to America where they would assist the CIA. (TW: The New World)
