I know that Captain America's flag draped body is not even cold in the ground yet, but in case they need a replacement, here's my Cap clone "Minuteman". He's named for the American Revolutionary War citizen fighters, and the mascot of my high school, Thomas Jefferson HS in Elizabeth, NJ.
I never came up with a origin for Minuteman maybe I'll get around to it one day. He's one of long list of original characters I need to update and get out there, somehow. I'll have to post them here, every now and then.
