Little more than walking batteries, GNK power droids trundle along as directed by their owners or their programming, recharging vehicles and machinery. They are often called “Gonk” droids in imitation of their simple vocalizations. There are many different models of power droid, most of them similar in appearance and habits as the well-known GNK. Power droids are common sights throughout the galaxy and little noticed despite their critical importance to both military and civilian life.
Growing up on his own during the age of the Empire, Ezra Bridger relied on his street smarts -- and subconscious Force abilities -- to survive. He became a con artist and small-time thief, doing what he needed to get by on his home planet Lothal. But this reality also hardened Ezra, who by the time he was 14 years old, had little trust for anyone. That would change with his introduction to the Ghost crew, a small band of rebels fighting back against the Empire. Ezra came to believe in their cause, and saw that he could help change the galaxy for the better. And with the help of Kanan Jarrus, he began to learn the ways of the Jedi.
Sabine Wren was a Mandalorian warrior, explosives expert, and graffiti artist -- qualities that came in handy as one of the first rebels against the Empire. Part of the Ghost crew, Sabine used her gift for bomb-making to great effect against the Empire, and would often mark her work with spray-paint tags. Her classic Mandalorian armor was notable for incorporating her own custom stylings, reflecting her creative-meets-rebellious spirit.
Ketsu Onyo was an old friend of the rebel Sabine, with both attending and escaping the Imperial Academy together. But they eventually took different paths. Ketsu became a bounty hunter, contracting with the Black Sun syndicate. During one job to recover a droid courier, she once again encountered Sabine, who looked to bring the droid to the rebellion. Their meeting was tense, but they put their differences aside to survive an attack from the Empire. In the end, Ketsu rejected an offer to join the rebellion -- for the time being.
The GX1 short hauler was a shuttle, ferrying commuters from one location to another. Piloted by an RX-series droid, It was commandeered by Sabine and Ezra of the Ghost crew while they looked to escape both Imperials and a bounty hunter. Eventually, with the Empire closing in, they abandoned ship and set the GX1 to explode, damaging an Imperial Light Cruiser’s reactor. The droid pilot, newly reactivated, was a casualty of the battle.
