When Marvel revived Captain America in the 1950's, it sparked a bit of creativity by Joe Simon and Jack Kirby too. They thought they could do it better and they did when the concocted a Cold War warrior named Fighting America. With an origin which felt somewhat like a cross between Captain Marvel and Frankenstein, they have a physically superior hero with the mind of his brother fighting against the Commie threat. Whereas the original Captain America stories were perhaps horror, these are spectacles of satire.
Here's a recreation of the original Kirby-Simon page from the origin story in which the two brothers are bonded by science.
And here's the artwork put to service by Simon for his humor magazine Sick. Love it!
