The Roboto I had as a child had silver legs without any metallic purple spray etc. I recently obtained an original Roboto mint in package. To my suprise there was a sticky purple color coming off of the silver and red parts of his legs. I thought it was ooze due to the plastic/paint deteriorating. This ooze/paint was also coming off of the gold parts of Jitsu and King Randor. My guess is that it is from deterioration. I would give Roboto a 6/10. He just didn't fit with the barbarian type mold I was after.
