If there's an explanation for Ripclaw's pseudo-albino coloring, I don't know what it is. Maybe he's really supposed to be an albino, which does occur occasionally in Native populations. Or maybe the creators thought his white skin was more marketable than brown skin.
Until recently I'd read only RIPCLAW #1 from the 1995 Image series. It was a typical Image comic, which means it was a confusing mess. A triumph of style over substance. Except for a brief scene of Bearclaw as a college instructor, it had no Native content and no redeeming value.
Let's see: Image was a major publisher at the time. I think it's fair to say Ripclaw is the worst Native superhero from a major publisher in the last 20 years. This character makes heroes such as Super-Chief and Black Condor seem like gems of depth and originality.
