From the Official Announcement: As the second season of Star Wars Rebels opens, the crew of the Ghost is now considered a very real threat to the Empire and has caught the attention of Darth Vader himself. Undeterred, the rebels seek out old friends and add powerful allies to their cause, forming the beginnings of a more formidable alliance against the Empire. To stop them, Vader will dispatch new agents to hunt down their growing coalition, determined to snuff them out before they can ignite a galaxy to rebellion.
The Star Wars Rebels panel will take place on the Empire Stage from 1:30-2:30 p.m. and will be followed by an exclusive screening of two new episodes later on the same stage, from 5:30-6:30 p.m. These all-new episodes will feature the series debut of Captain Rex, Captain Gregor and Commander Wolffe - three clones from the previous Star Wars animated series, Star Wars: The Clone Wars. They join another fan favorite from The Clone Wars – Ahsoka Tano – who made her Star Wars Rebels debut in the final episode of season 1.
Star Wars Rebels returns with new episodes this fall on Disney XD.
