That’s a good question: Do we want to see “any Chiss” species in Star Wars Rebels?
Well, you saw Agent Kallus ( agentkallus77 ) was suppose to be a Chiss. For some reason they went through many iterations of his character’s look and decided to create him as we see him today. So it is possible the creators thought of having “any Chiss” in the show.
But our group wants THRAWN specifically because of the known pre-”Heir to the Empire” backstory, which we think can be retconned. We have to accept those changes to his backstory pre-HTTE. We cannot vice grip that part except for the following:
THRAWN IS A CHISS (a guy with red eyes and blue skin)
THRAWN IS A MILITARY GENIUS AND STRATEGIST
THRAWN CAN BEAT FORCE USERS WITH HIS LOGICAL MIND
THRAWN IS AN IMPERIAL OFFICER AND LEADER
Those ideas above are what we won’t negotiate on. Other than that, I mean…yeah…C’boath might have to be negotiated. How many wacked out old Jedi do we really know? I mean he was a clone, right? I don’t know? Is that something that your truly tied into?
Then how much “origin” are we going go into about THRAWN? Do we have to? That needs to be worked out and joining one of our planning committees to implement that is what we need help on:
