It’s been a while since I’ve done one of these, but I’m fairly confident I found a doozy here! Check out the Hulk Rage Cage produced by Fun Stuff in the late 70s. I’d never heard of this one, but I love the idea of a toy designed to fully capture the Jade Giant’s destructive capabilities. On the other hand, I’m not sure how much replay value this would have after the first few bar-breaks.
What’s even crazier, though, is that this idea has persisted over the years. It looks like Toy Biz made one as part of the Marvel Super Heroes line in the early 90s, but also brought it back a few years later in a line dedicated to the Hulk’s UPN cartoon! Nice work Fun Stuff!
