Alan Tudyk, who voices K-2SO, and Animation Supervisor Hal Hickel recently revealed what went into building the droid’s backstory.
Speaking with Comicbook.com, Tudyk and Hickel explained that before K-2SO was captured by the Rebellion and reprogrammed, he was an Imperial drone, “scurrying around” and following orders.
We figured the Rebels are kind of rough and tumble and they’re not going to be too precious about it.
We decided to keep it, it’s kind of scratched up, but you can still see it.
