Fantastic thread. This is a character that hasn't always been handled well, but remains a favorite, as does Namor. All Jim Hammond fans need to check out Captain America #45, currently on sale. Ed Brubaker is doing something with the character, and Namor is coming in next month as well. Should be a good story.

it's Hammond Vs. Himself in the pages of both Invaders Annual #1 and Avengers #71.......both are inconclusive battle(stalemates) from different perspectives(those crummy avengers would have you believe they won, pfft) :
I always assumed it's because he was meant to be potrayed as less of a robot and more of an artificial, synthetic human being(which he usually is).......But really, no ones knows.lol
