The Bend 'n Flex figures are approximately 5" tall. All five of the first series 8" figures are represented, but Galen is the only one from the second series to make it to this format. Zira is the rarest of these figures. Mego also produced Bend n Flex Superheroes and proposed the format for Star Trek and Kiss.
The card backs are all identical. Notice Galen is inexplicably armed with a spear.
This is an original retail counter display box for the figures. It's extremely rare and may be the last one in existence. (Pictures courtesy of Mark Smolen)
