Krinn is a Vulcan gangster on M'Talas Prime who forces Worf into a duel and then helps him and Raffi break into Daystrom Station.
Krinn is a Vulcan crime boss on M'Talas Prime and a close associate of the Ferengi Sneed, whom he regarded as a brother. He is linked to the theft of weapons from Daystrom Station.
In Imposters, Worf and Raffi confront Krinn, who forces them to fight each other to the death. Raffi stabs Worf, who fakes his death, then overpowers Krinn's crew and takes the gangster captive. Krinn gives them a device that exploits the station's security system, allowing them to break in. He was played by Kirk Acevedo.
