Reuben Kralich was the leader of the TIE fighter Xenon squadron in 0 BBY, who managed to defect most of his entire squadron to the Rebel Alliance. He originally led the defection during the Battle of Yavin, where he and his wingman were successful in destroying six spotter towers that gave the precise location of any fighters along the equatorial trench. After the destruction of the Death Star, he led his forces through several areas, while at the same time being pursued by the Empire, to seek alliance against the Empire.
