The ChR Predator was a Z1-class Romulan Bird of Prey.
History[]
In 2285, the Predator was part of Commander Lazar's squadron. It had captured a shuttlecraft with a sick Andorian on board that had entered the Neutral Zone. Though Captain Tr'Aet killed the Andorian, he and his crew then became infected by the Andorian's virus. (TOS - The Doomsday Bug! comics: "Death Ship!", "Stand-Off!")
