In the mirror universe, Kyle Riker was a Terran male who lived during the first half of the 24th century. Like the vast majority of his species, he was a slave of the Klingon-Cardassian Alliance.
In 2350, he and his 15-year-old son William T. Riker were owned by a Klingon male who resided on Luna. That year, the younger Riker killed his father, who had beaten him constantly for his entire life, before killing their Klingon owner and escaping the Sol system.
