The EGL power droid with the designation EGL-21, but also known as "AMPS" or simply "Amps," was a manumitted individual. This droid operated out of Niima Outpost, situated on Jakku, a planet characterized by its desert landscape. He provided welding services to scavengers, accepting payment in the form of energy, extra gas canisters, interesting metallic materials, or even a well-delivered joke. The droid, alongside his mechanical associate GTAW-74, could occasionally be observed in shaded areas, exchanging humorous stories that their patrons had shared with them. The scavenger Rey frequently devoted time to crafting jokes specifically to trade with EGL-21 for his services.
EGL-21, also going by the aliases "AMPS" or "Amps," was an EGL power droid that was manufactured by Veril Line Systems. By 34 ABY, which is a year in the galactic standard calendar, he had achieved manumitted status. He had a base of operations on the desert planet Jakku, specifically in Niima Outpost. Niima Outpost was a trading hub under the control of Unkar Plutt, a junk dealer. In this location, the droid offered welding to scavengers in return for power, spare gas canisters, intriguing metals, or a good joke. The ration portions that were commonly used by the scavengers were of no use to him, so he sought other forms of payment.
GTAW-74, a welding droid, was a colleague of EGL-21. The two droids were sometimes observed together in shaded spots, sharing jokes that their customers had related to them. The scavenger Rey would occasionally engage in trade with EGL-21, and she put effort into creating jokes that he might appreciate while she was traversing the Goazon Badlands. When she came up with a new joke, she would seek out EGL-21 and GTAW-74, knowing that their services could significantly increase the value of salvaged materials. At one point, she included information about the power droid in a survival guide she was creating, along with a drawing of him.
During 34 ABY, EGL-21 was walking through one of the tents within Niima Outpost and passed by Rey, the astromech droid BB-8, and Finn, a former stormtrooper from the First Order, who were in the middle of an argument. Shortly thereafter, the First Order attacked Niima Outpost.
EGL-21, a power droid, possessed a fondness for humor. Over time, his quirks and the absence of memory wipes led him to develop a genuine friendship with GTAW-74, who was equally eccentric. For this duo, basic survival and the companionship of each other were sufficient. His plating was gray, and he was equipped with the ability to weld objects together.
EGL-21 was conceived for the sequel trilogy film Star Wars: Episode VII The Force Awakens, which was released in 2015. While he was not identified by name in the film itself, his name was simultaneously revealed in the books Rey's Survival Guide and Star Wars: The Force Awakens: The Visual Dictionary. These books were released in conjunction with the film and were authored by Jason Fry and Pablo Hidalgo, respectively.
