Alan Moore, Steve Bissette, Rick Veitch
In the 1963 line of comics by Alan Moore, Steve Bissette, and Rick Veitch, we got to read 1993-era satires of comics from Marvel's Silver Age. Each 1963 character stood for a character of that bygone era from the House of Ideas. Iron Man's counterpart was a half-human/half-robot named the Hypernaut, who lived in a nicely Escheresque headquarters, in the shape of a Penrose triangle.
