Collins served as the chief engineer of the ISS Indomitable when it went into battle near H'atoria. Collins was responsible for sending a distress call that reported that both the captain and first officer had been killed. This distress call caused Commodore Robert April to take remote control of the Indomitable and slam it into a Klingon research outpost, killing Collins and the remaining crew. (TOS - Mirror Universe short story: "Ill Winds")
