(Continued from here and here.)
While I recall at least a couple more designs (one was a flying woman with big hair like Starfire, and I recall a sort of girl version of Polar Boy... there may well have been more), this is the last one of these designs that I can lay hands on. He's basically the Atom crossed with Ferro Lad, plus a cape. His atomic thingies are probably intended to be a Captain Atom riff, but the result, regrettably is more reminiscent of Firestorm.
These might or might not have made the grade if I'd had any follow-through, but we'll never know. As it is, the only marks I left on the world of comics in my teens were a letter in Neil the Horse and a mention in Cerebus. C'est la vie.
