In 1978, Remco released Energized Spider-Man that was able to "climb", "lift" and even ride a helicopter standing up! (Spider-Copter sold separately) Spider-Man's adversary, Green Goblin, was "Energized" too, and could cut through Spider-Man's webbing. Energized Spider-Man was so popular, eventually an Incredible Energized Hulk followed, with DC characters licensed next. Energized Superman had a retractable fly wire while Energized Batman had a bat-grapple.
The Energized Spider-Man goes for quite a bit these days, well over $100.00 in the original box, which is beyond my budget for a toy. Occasionally I see a battered and beaten one at an antique shop or flea market. Still, I did finally get a Mego Spider-Man for a good price after years of searching. And searching is half the fun.
