In the mirror universe, Zim Brott was a Bolian male who lived during the 24th century. He was a member of Captain Cal Hudson's cell group in the Terran Rebellion. He had at least one wife, who was also a rebel and served as medic for the group.
In 2375, Zim assumed the role of executive officer of Hudson's newly constructed Defiant-class warship with the rank of commander. However, he, his wife, Hudson and many other rebels died when the Empok Nor shipyard exploded. (DS9 - Mirror Universe novel: Saturn's Children)
