Star Wars Rebels introduced a collection of new heroes to the galaxy far, far away. The series took place in the four years prior to Star Wars: Episode IV - A New Hope, revealing how the Rebel Alliance came to be. More specifically, the series followed the adventures of one particular rebel cell: the Spectres. This ragtag band of heroes, who flew aboard the Ghost, had gathered from all corners of the galaxy to become an unlikely family. Among them were the two Jedi, Kanan Jarrus and his Padawan, Ezra Bridger; the Mandalorian outcast-turned-street artist, Sabine Wren; ace pilot, Hera Syndulla; the cantankerous astromech droid, Chopper; and one of the galaxy's last Lasat warriors, Garazeb Orrelios.
