Chopper was the resident droid of the Ghost, assisting the crew in everything from ship maintenance to combat -- even though he didn't always want to. After many years of repairs and patch jobs, Chopper had a beat-up, worn look that matched his sometimes cranky personality. Aesthetics aside, he was an essential part of this small rebel team, and ultimately, was loyal and heroic.
Proud and honorable, AP-5 was a droid that served as a navigator for the Republic military during the Clone Wars. Following the formation of the Empire, however, he was reassigned to inventory. While the position did not take advantage of his gifts, he performed his duties without complaint -- despite threats and disrespect from his Imperial commanders. It was only after a fateful meeting with the rebel astromech Chopper that AP-5 came to see he did not have to serve the Empire. He helped Chopper escape capture and defected to the rebels, helping find a safe haven away from Imperial forces.
The captain and heart of the Ghost crew, Hera Syndulla was a gifted pilot and leader. While Hera was a strong commander -- and especially adept at dogfighting with TIE fighters -- she was also warm and nurturing. The Twi’lek could bring out the best in her team, which consisted of very different personalities, making them believe in themselves, each other, and their struggle against the Empire.
