So, my favorite iteration of the Hulk is Bruce Jones' "Return of the Monster" era Hulk. Yeah, most people complain about it now cause the Hulk was seldom seen - like a monster who only pops up now and then - but it was brilliant and so against-type. Made a compelling, fascinating read that I still need to finish (read the first two years, but got away from comics for a while, so need to go back and fill in the gaps).
One of my favorite things was that Bruce Banner shaved his head - and the Hulk was bald TOO! SO cool. Plus this Kaare Andrews covers were unreal cool.
