Sobi was a Brekkian involved in the selling and shipping of the drug felicium from Brekka to the planet Ornara, supposedly to help treat a plague on that world in 2364.

In truth, the felicium had cured the plague years ago and was now simply a narcotic. Sobi and his people were aware of this, but determined to continue exploiting the Ornaran's addiction for their own profit. (TNG: "Symbiosis")
