The initial run of Earth 2 was written by James Robinson, who had some experience writing about that aspect of the DCU in his Starman series. He created the idea that Solomon Grundy would be an agent of the Grey (which was introduced in a Swamp Thing annual in the 80s, and was fleshed out a few years later by Doug Wheeler in the Rise of Matango/Quest for the Elementals stories.) Anyhoo, I suspect that after Snyder came out with The Rot as a thing, the younger (and probably less experienced) writers on the world's end series just adopted The Black instead. (I'm not sure anyone regards World's End as canon right now anyway).
