This bar visitor was encountered by CaptainJonathan Archer and T'Pol while searching for Menos on the Pernaia Primemoon. In a shootout between Menos and Archer, Archer bumped into this tall alien and the tall guy said something in an unknown language to him. Archer left the alien alone and replied, "I couldn't agree more." (ENT: "The Seventh")
This individual was played by Vincent Hammond, who was credited as "Huge Alien" in the end credits.
