Gorta

From Memory Alpha, the free Star Trek reference.

Gorta was a Dopterian who, in 2370, unwisely entered into a mining operation with Lursa and B'Etor on Kalla III, a planet in Pakled space. They managed to mine 10,000 kilograms of magnesite ore.

Lursa and B'Etor then betrayed Gorta, took the ore and left him stranded on Kalla with nothing. He was later picked up by the USS Enterprise-D. (TNG: "Firstborn")

Gorta was played by Colin Mitchell.
