The Incredible Hulk is a rampaging force of nature that destroys everything in his path — but he's also a tragic figure. And judging some early concept art for Ang Lee's movie version from artist Jim Carson, the Ang Lee Hulk could have been the saddest of all.

Carson posted some concept art, showing how expressive — and in a few cases, downright creepy — his early Hulk designs looked. Plus some designs of the Gamma dogs, and Bruce Banner's mutated father. Check out some of our favorites below, and more at the links. [Jim Carson, via Comic Book Movie]
