The IRW T'Met was one of the Romulan warbirds that met the hijacked USS Prometheus in 2374, only to be fired upon when two holographic doctors regained control of the ship.
The T'Met appears in the Voyager episode Message in a Bottle. Romulan agents have seized the experimental USS Prometheus and are taking it to a rendezvous with the Tal Shiar. Voyager's Doctor, transmitted across the galaxy through an alien relay network, joins the ship's own Emergency Medical Hologram to stop them.
The two holograms gas the Romulans on board and take the bridge just as warbirds, the T'Met among them, arrive and are joined by pursuing Starfleet ships. The Romulan commander hails the Prometheus expecting his own officer to answer.
In the confusion the doctors trigger the multi-vector assault mode, and the three sections of the Prometheus destroy one of the warbirds, after which the rest withdraw.
