Promethium is a metal alloy in the custody of S.T.A.R. Labs in Metropolis. It is kept in the Red Room, a high security facility dedicated to collecting and analyzing foreign technologies. After Victor Stone was caught in a backwash of radiation from the Boom Tube, Silas Stone attempted to save his son's life by first giving him a Promethium skin graft then injecting him with untested nanites. Coupled with the alien artificial intelligence in the radiation, the Promethium aided in saving Stone and turning him into Cyborg.
