Dec Hansen was a human male scavenger from Ques, a swamp planet in Hutt Space. Hansen was an only child, so his mother built him a "brother," the droid AG-90. Hansen grew up with AG, and the two eventually joined the Resistance against the First Order, serving as cadets in J-Squadron. At the Resistance base on D'Qar, Hansen became reputed as a troublemaker, and in 34 ABY, he and a few other members of J-Squadron were sent on a scavenging mission to Vodran as a punishment. However, Hansen and fellow cadet Sari Nadle became separated from the group after being attacked by Vodran's fauna, and they were forced to flee the planet.
