Moyner Falqnerr was the sister of Caren Falqnerr. She is a Byrnian that, as is the case with her species, once charged by the energy spectrum of a yellow sun, has the ability to shapeshift in to a monstrous form when angered.


On her father's 50th birthday, Moyner and her sister, Caren, poisoned him, thus killing him, in order to take over their family's intertron business. However, they were charged and imprisoned in Fort Rozz, inside cages made of intertron. However, Fort Rozz eventually crashed on Earth, allowing them to escape. However, the sun's rays affected them, causing them to transform in to monstrous creatures. In the following 10 years, Caren was able to keep her transformations under control, but Moyer had much less luck, forcing her sister to keep her in one of the intertron cages for her own safety. However, she eventually escaped. For several months she searched for her sister, eventually finding out that she had been killed by Agent Danvers of the D.E.O.[1]
