Doc
this was the nickname given to the FX-series medical droid modified by Massad Thrumble. Doc - originally designated AOI-C - was a one-of-a-kind, and had the upper section of the FX series mounted on a treaded base. Thrumble programmed the droid with top-of-the-line medical and surgical skills, and gave it the necessary tools to perform surgery on any number of species. Doc considered the reprogramming of Guri - who rescued the droid from Spinda Caveel - to be a "wonderful technical challenge."
