One of the four Ferengi pirates who incapacitate the Enterprise crew and plunder the ship, greedy and easily turned against his companions by rumours of a secret vault.
Grish is a Ferengi who appears in the Enterprise episode Acquisition, played by Matt Malloy. With Ulis, Muk and Krem he boards Enterprise after a gas released from a salvaged artefact renders the crew unconscious.
Grish helps carry the loot to the Ferengi ship, taking everything from food and equipment to unconscious women he hopes to sell. Like his shipmates he quotes the Rules of Acquisition and suspects the others of cheating him.
Trip Tucker, the only crewman left awake, exploits that mistrust by sowing the idea that Archer has a vault full of gold. Grish is stunned and captured during the search for it, and ends the episode a prisoner of his former subordinate Krem.
