Alton Kastle was a human male journalist who worked as a broadcaster on HoloNet News on the planet Lothal. As a broadcast journalist, he helped spread propaganda for the Galactic Empire, including propaganda about Wookiees and local unemployment rates. The Leonis family sometimes watched news broadcasts by Alton Kastle. While Leo Leonis believed the Imperial line, both Zare Leonis and Tepha Leonis came to learn that Kastle was a stooge who often delivered news that was either carefully manicured truth or entirely fictitious.
