Cumberlayne Aresko

Commandant Cumberlayne Aresko (codenamed LRC-01) was an Imperial commander who appeared in the Disney XD series Star Wars Rebels, voiced by David Shaughnessy.

Background
Aresko was a loyal commandant to the Galactic Empire, stationed on Lothal. He was known to be cruel and unsympathetic to all those around him, especially to those who speak freely about the Empire's oppression across the galaxy.

Star Wars Rebels: Spark of Rebellion
Aresko, alongside Taskmaster Myles Grint were interrogating a citizen for identification until he had him arrested under a charge of treason. However due to a false "Code Red" made by Ezra Bridger, Aresko delayed the arrest and ordered Grint and his accompanied Stormtroopers to the rendezvous point, where a group of Speeders were being loaded with Imperial crates.

Soon after realising the "Code Red" was a false alarm, he was present when the Rebels attempted to steal the crates. Hours after the incident, Aresko met up with Imperial Security Bureau Agent Kallus, who informed him that he was not of the first Imperial station to be ambushed, and that this was one of many rebel-related attacks. Considering this to be the spark of a rebellion, Kallus revealed to Aresko that he was determined to put an end to the attacks.
