The first such items were the Super Softies (a series of plush heroes) and the Bend N Flex line.
The second series which introduced the villains and Supergals, came on shorter cards that had improved graphics, the 8 male heroes were reissued on the "Short cards", it is not know which is more valuable.
In terms of rarity, the most commonly found MOC figures are Mr. Mxyzptlk and Tarzan, while the Supergals and Riddler especially would be among the most difficult to find.
While the line was sold internationally, no foreign packaging variants have ever arisen. The 1974 Mego Catalog shows a carry case for the Bend N Flex line but it was never produced. It is largely believe that Mego did create display boxes for the Bend N Flex line as they did for the Planet of the Apes series but non have surfaced.
Over the years, the Batman Bendy has seen a couple of reissues, starting with Australia in the late eighties but recently a black movie version has popped up in Africa. It seems to suggest that figures mold is still out there to this day.....
