Jeff Garvey was a crew member onboard a spacecraft commanded by Gordon Lowery.
SSS agent Marc Cory crash-landed a small spacecraft on the planet Kembel with Lowery and Garvey onboard.
While out in the jungle, Garvey was stung by a Varga plant, and attempted to kill Lowery, but was shot by Cory. He then completed his mutation into a Varga plant. (TV: Mission to the Unknown)
