I picked up Helen at the Wayne NJ Toy Show. I bought her from Steve from Toy Hunter. He had a big bin of loose figures that I was digging though. There were a couple figures I was interested in, but for loose incomplete figures I felt like he was kind of asking to much. So Helen ended up being my only purchase from his bin of figures.
Originally Helen came with a blue backpack. It sort of clips over her shoulders and then there is a strap that goes around her waist. She didn't come with it, but I previously bought a complete set of Bionic 6 weapons on ebay. Even though the auction didn't mention it, I am 99% sure that the weapons I picked up were reproductions. The more rubbery accessories like Helen's backpack just aren't quite flexible enough. It's really hard to attach the belt. I have an original Meg (the daughter) belt as well as the one that came in the set I bought online and they aren't the same material.
Check out this awesome 80's commercial for the Bionic 6 toy line. I always liked how the figures started out as metal in a mold in these ads. There is a little bit of stop motion animation in the ad also.
