...the GG posed as a successful sculptor who specialized in life-size female figures? Well, it turned out to be the GG freezing women into stautues and selling them. Not a bad twist on the GG formula, I thought. And fairly creative for a single-issue story.
About the same time, the Radioactive Man took a job as a regular (non-green) human being at the huge science-based corporation so he could use their resources to conduct his own experiments. That made sense to me; no reason that he necessarily has to be green, toting a glue gun, and wearing a mini-tunic.
Over the years, we've seen many, many criminals used creatively and imaginatively, and also the opposite: some have been ruined by 'progress,' like the Plant Man and Black Tom.
I see no reason why the GG can't fly around in his costume causing havok; maybe he could have the Fixer make him invisible when he wants to be, so that he can sneak up on those he wants to turn to stone.
I belive he'd make an excellent addition to any new Masters of Evil.
Those were nice IRON MAN issues, and they were just a few issues prior to the big Madame Masque shooting in #238.
