Captain America (1968 1st Series) #436

In the blazing Arizona desert, the Sentinel of Liberty fights for his life against the Cobra and Mister Hyde! Stripped on his body armor, Cap desperately tries to make quick work of his long-time foes before his muscles seize up again! But the savage super-villains smell blood in the water! And when the star-spangled avenger's paralysis returns, Captain America's fighting chance appears over. Meanwhile back at the Cobra's luxurious compound, Free Spirit and Jack Flag flee from the Serpent Society! The young heroes' hopes for escape receive a giant boost when Giant-Man (aka Hank Pym) arrives on the scene! The seasoned avenger helps Cap's protégés get away, and then scours the desert looking for the paralyzed Living Legend! Can Hank (the same man who pulled Steve Rogers from the Arctic Ocean way back in the classic Avengers 4) pull off another amazing rescue?
