Star Wars Rebels introduced a new band of intrepid heroes to the galaxy far, far away. Traveling together aboard the Ghost, the rebel cell known as the Spectres included many faces that have reappeared on Ahsoka. This saw the likes of Hera Syndulla, Sabine Wren, Ezra Bridger and Chopper making the leap to live-action. With Zeb Orrelios appearing on Season 3 of The Mandalorian, the only Spectre who has not appeared in live action is Kanan Jarrus.
