Though im sure the Empire would be the main threat to the crew of the Ghost. I do hope that we get other forms of evil, that are not allied to the empire, and perhaps even anti-empire themselves. Pirates? Other kinds of criminals (perhaps hutts)? Terrorists (would be interesting to show an anti-empire faction that acts very immoral, murdering civilians to make a point, etc, to achieve their ends, showing that just because someone opposes the empire does not always make them apart of the good guys)? I also wouldn't mind seeing a rouge darksider, that is not allied/working with the empire/sith (rouge ex-jedi turned to the darkside and is out for revenge against them, or perhaps a darksider that is ex-imperial). Would be nice to have a force sensitive threat for the good guys that is not working for the empire/sith (we got something similar to that in TCW, would like to see it return). What kind/type of villains besides the empire, would you want to see in Rebels?
