I wear my fanfare for Power Girl on my sleeve. Of the original Infinitors, I was a fan of Jade since my introduction in one of DC's in-house ads. I was initially giddy to see her appear in the pages of Green Lantern but was soon turned off by how she and the former GLs were treated in Kyle Rayner's one-horse town. Hector Hall fared better (for a time) as Dr. Fate.
I'd be very interested in a book where the Infinitors are given their due as the heirs apparent to the JSAers.
