He and his brother used the ship to work for the Tellarite Mining Consortium. Skalaar retrofitted the ship's engines himself. The Tezra was seized by the Klingon Empire after Skalaar crossed into Klingon territory while hauling fire salt.
He became a bounty hunter to pay the impound fee; however, the ship had been cannibalized by the Klingons several years earlier. During his time as a bounty hunter, he made enemies with another bounty hunter named Kago-Darr.
In 2153, he captured the Human Jonathan Archer, who had been the only person to ever escape Rura Penthe, and on whom the Klingons had put a high price. Skalaar met Archer and his ship, the Enterprise, in orbit of a Class M planet, where he tricked him into going to the airlock, where Skalaar kidnapped him after a small struggle. He brought him aboard his ship and headed to a Tellarite space station where his brother worked. He later headed towards Klingon space. (ENT: "Bounty")
