He was originally one of Wonder Woman's Nazi villains from the Bronze Age. I remember the mask and ax. I personally didn't find him one of Wondy's more compelling or memorable villains, but the Armageddon name does go well with the Four Horsewomen theme. It seems they gender bent the villain. Personally, design-wise I like the gender-bend, but I wish the artists had kept both Armageddon and Genocide with no hair or shorter hair. The long, feminine almost glamourous hair doesn't go well with their monstrous designs.
