Masking transponders, made by the Corellian Engineering Corporation, were used to transmit ship identification data; they were reprogrammable so that they could project false profiles for those who wished to not be seen. When the Ghost rebels needed to escape Lothal, they used Lando Calrissian’s transponders to send out the same signal throughout the planet. As a result, the Empire was confused, and their ships were forced to investigate each signal. This gave the rebels the opportunity they needed to jump into hyperspace.
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.
