- "We were on a routine patrol and ran into one of your rebel friends, a Lasat mercenary who worked for Saw Gerrera. I… was lucky, knocked out by the first blast. I came to, but found I couldn't move. And then I saw… him, the Lasat, calmly walk through smoke and fire to finish my unit off, one by one. The injured never had a chance. Always wondered why he let me live."
- ―Alexsandr Kallus, to Garazeb Orrelios
During the reign of the Galactic Empire, a male Lasat mercenary worked for Saw Gerrera and his Partisans during their campaigns on the planet Onderon. A unit of Imperials, including Kallus, was sent to Onderon to deal with the rebels. This mercenary killed most of the unit, but Kallus survived. The mercenary continued to offer his services to the Partisans and eventually became a member of a crew led by Reece Tallent, and was with them when they arrived at Saw Gerrera's Wrea outpost in 7 BBY. The Lasat was described by Jyn Erso as rarely speaking.
