I had a Superman head, from Kenner's Super Powers series, that came from a very beat up Superman. So much so, that a chunk of his molded hair had been cut off. I used some wood glue, and some black paint, to give him his hair back (Molded Hair Club for Action Figures?), but also sanded off his spit curl, just for fun. From there, the head sat around until I found a Bruce Wayne with most of his torso paint scratched off. I had to sand down part of the neck pin, just to get Superman's head on.

A friend saw this on my shelf and asked when did Clark become a cat burglar.

So I thought, what if Clark hadn't become Superman, but he was also a secret agent? Maybe he worked for SHIELD
