You likely also know the Pilot episode proton pack (on which the Kenner figures modeled their packs).
But what iteration was this in a single shot of Killerwatt?
It looks like some vestigial tail of the design process -- almost as if the packs were drawn more accurately at first, but with some cartoony elements signaling what the final design would be.
All I could see as a kid was that red box with the diagonal line that shouldn't have been there. It always bugged me, but I couldn't see any of the other details. But now, with better resolution and Photoshop, I've got a better look.
Someone in this forum must have noticed or talked about this already, right?
