I remember watching a video a couple years back from a toy show (maybe in Long Island) where Doc Mego mentioned (or actually had the protoypes at the show) of the figures that were not made prior to Mattel ending the line. I was hoping to find that video, but can't remember where I saw it. From memory, I was thinking the 4 figures might have been Robin, Bizzaro, Supergirl and Hawkman, but I could be wrong. Anyone remember this?
