Scientists were researchers in the fields of biology, chemistry and physics. The Kaminoans were scientists who specialized in cloning technology. Galen Walton Erso was a scientist and polymath employed by the Galactic Empire to be a crucial part in the development of the Death Star. Zare Leonis's parents, Leo and Tepha Leonis, were agricultural scientists employed by the Imperial Ministry of Agriculture. Galactic Emperor Darth Sidious enlisted the scientist Cylo to look into possible replacements for his apprentice Darth Vader. The female Tulon Voidgazer was a scientist who served aboard the Death Star superweapon before its destruction.
