Omag was an obese Ferengi weapons trader during the late-24th century. He was quite fond of the song "Melor Famagal". In 2368, he stole a Vulcan transport, the T'Pau, from Surplus Depot Z15 and delivered it to a Barolian freighter at Galorndon Core, near the Romulan Neutral Zone. William T. Riker followed him to Qualor II to seek information about missing Vulcan ships. Omag was thoroughly disreputable and refused to give any information. Riker threatened to revoke his travel in the sector which would severely hamper his arms dealing. After the threat from Riker, he revealed that the Romulans were involved in the theft of Vulcan ships. (TNG: "Unification II" )
