Annorax is a Krenim officer and a genius temporal scientist. He uses his advanced understanding of time on a mission to restore the Krenim Imperium to power. Annorax creates a weapon that eliminates anything from a molecule to a civilization from the space-time continuum, creating an alternate timeline where it doesn't exist. This plan for world-changing domination runs afoul of the crew of the U.S.S. Voyager.
