Menos looks at a holographic image of his family
Menos was a 22nd century Vulcan operative. He was assigned to infiltrate a cell of smugglers but eventually became one himself. He smuggled dangerous bio-toxins that were used to create transgenic weapons.
T'Pol was sent to apprehend seven rogue operatives and succeeded in capturing five of them. Menos and another rogue operative, Jossen, escaped. Several years later, she tracked them to the jungles of Risa, where she killed Jossen. Menos managed to escape again. Disturbed that she had taken a life, T'Pol undertook the Fullara, a Vulcan technique used to suppress memories.
In 2152, while serving on the Enterprise, the Vulcan High Command contacted her and informed her that Menos had surfaced again in the Pernaia system. She asked her commanding officer, Jonathan Archer, to help her apprehend him. After they had captured Menos, T'Pol's memory of killing Jossen returned. Menos used this as an attempt to escape. T'Pol stopped him and almost killed him, but was persuaded not to by Archer, who told her that she was only to capture Menos, not judge him. (ENT: "The Seventh")
- Menos was played by Bruce Davison.
