EGL-21, also know as "AMPS", was a masculine manumitted power droid that lived in Niima Outpost on the desert planet Jakku around thirty years after the Battle of Endor. He welded objects for the scavengers on Jakku in exchange for power, spare gas canisters, interesting metals, or a good joke, as he couldn't eat rations. The droid and his mechanical colleague GTAW-74 could sometimes be spotted in the shade trading jokes that their customers had brought them, and Rey often spent time thinking up jokes to trade with him for his services.
