John Smith

Major John Smith was an ONI scientist working aboard the UNSC prison vessel, in 2552. While aboard he studied several Flood-infected Elites in hopes of finding a cure to their disease. He also conducted research in hope of turning the Flood into warriors for the UNSC. Whether ONI approved of this is unknown. When the ship was overridden by the Flood, he remained hidden inside a small room until he was discovered by Lopez's squad. He later escaped aboard their Pelican, betraying the squad.

It is unknown what happened to him afterwards, but he was likely court-marshalled, as The Red Horses's captain planned to have him.
