Oh yeah, and Black Terror (although nearly unrecognizable in this incarnation) was included in a HEROES OF THE NORTH: DARK ORIGINS (another superteam) one-shot from 2012. Not sure if that was a Kickstarter gig or not, but after a cameo appearance in the follow-up HOTN #2, that was the end of that. "If a tree falls in the forest, and there's no one there to hear it, does it make a sound?" Same can be said for a "blink and you missed it" Golden Age hero revival.
