Tonight one of my players created a DUM-series pit droid dubbed "DUM-E" repurposed as a doctor and running from a charge of malpractice. DUM-E's motivation is to Overthrow the Empire, but cannot set idley by and ignore his programming to save lives. His chassis is Yellow with red racing stripes down the center and he frequently says "Roger roger" due to the battle droid vocabulator someone installed in his system long ago.
Man, I love character creation.
