The most feared of course would be Lil Vader. Quiet for the most part, but always in control. No one messes with him or his Empire Patrol People.
And of course there is (literally) the biggest bully of them all. Big J and his sidekick lackey Crumbs.
Of course, there will be all sorts of other bad boy incarnates like Boba, Greedo, Maul, and others.
Tomorrow, we'll show a few of the good guys.
