Khata'n Zshaar was the captain of an Arkonian destroyer. In 2152, Enterprise NX-01 was looking for Commander Tucker, who had crashed in a nearby system annexed by the Arkonians. Zshaar hailed Enterprise and ordered it to leave the system. Once both men were rescued, Khata'n Zshaar visited Enterprise to retrieve his man, and bid Archer farewell. He wasn't overly friendly towards Archer, but both showed a mutual respect. This first contact was more successful than that of the Vulcans in establishing relations with the Arkonians. (ENT: "Dawn")
