In the mirror universe, Enrique Muñiz (also known as "Quique") was an active member of the Terran Rebellion against the Klingon-Cardassian Alliance who served on the Defiant under the command of General Miles "Smiley" O'Brien.
In 2375, Muñiz was considered by many to be both loyal and faithful to the cause, but O'Brien was forced to investigate him when faced with the task of exposing an Alliance spy in their ranks and Muñiz had began receiving and sending encrypted messages through a loophole in Terok Nor's communications system.
The spy later turned out to be Sito Jaxa and Muñiz was only sending and receiving messages to maintain contact with friends whom he made in other rebel groups such as a group of his friends informing him of deserting the Alliance on a stolen ship called the Vesuvius, and receiving a strip-dance video from his lover on his birthday. O'Brien called him "a lucky, lucky man". (DS9 - Mirror Universe novel: Saturn's Children)
He was killed in 2378 while the Defiant was attempting to prevent the Klingon renegade Krona from detonating Bajor's sun B'hava'el with a trilithium explosive. (ST - Mirror Universe novel: Rise Like Lions)
