I dunno, it would be very hard to fit in a twisted looking guy with a cackling voice and wearing a hooded robe into this show and have any one of these much more realistically depicted people throw their hands up and say "wait wait wait, we are listening to THAT GUY?"We have to get some sort of Palpatine appearance at some point right? Even just a 2 second appearance on a news monitor. This show doesn’t care about putting in fanservice cameos, but in this case Palpatine is the Emperor of what the protagonist is rebelling against. It would be weird NOT to show him.
