I love the Zombieverse from Marvel Zombies , and what better Marvel Zombie could I make other then Cap himself.
I took the bodie of a wwf wrestler and drilled the cr*p out of is bodie.
I use tooth picks for the bones.
for the head I use a todd McFarlene military soldier head and drilled a hole in is eye, took the top of is head off ,used some hot glue for the brain, then I painted it all and glued the head on the bodie and rebuilded the neck. one more layer of paint later and voila ,Zombie Captain America.
I know he's not totaly comic accurate but I like him.
