Rekar

From Memory Alpha, the free Star Trek reference.

Rekar was a Romulan Commander secretly working for the Tal Shiar.

In 2374, Rekar led a successful hijacking of the Federation starship USS Prometheus, killing the Federation crew. He and his officers were the first to prove the effectiveness of the experimental multi-vector assault mode in combat conditions by disabling a pursuing Nebula-class starship.

Rekar and the others were eventually rendered unconscious by anesthezine gas, introduced into the life-support systems by the Doctor, working together with the Prometheus' EMH Mark II. The vessel was then returned to Starfleet control. (VOY: "Message in a Bottle")

Rekar was played by Judson Scott.
