"Butch" is apparently an abandoned name concept for Sparkplug Witwicky's son. At OTFCC 2004, Bob Budiansky stated that the story treatment he received from Hasbro used the name Spike. However, his copy of the treatment has the name crossed out and replaced with Buster in his own writing. Budiansky could not recall the details, but speculated at the convention that Hasbro had asked for the name to be changed.
