I hate to mention this but of all I heard about how great the Joe Simon / Jack Kirby team was to comics, and their is no doubt they did a lot for the industry. I think almost none of their characters really did last.
Only Captain America was their standout, and he was just a blatant ripoff of The Shield. So much of a ripoff that Cap’s triangle shield was the exact design of The Shields chest symbol. The character of The Shield was created for MLJ Publications and the first comic book patriotic hero.
Bucky was to Cap, just an unoriginal knockoff of Robin. Everyone back then copied the Batman / Robin team idea.
And those characters are the only real claim to fame most people know of the Simon / Kirby team and the characters they created.
The Red Skull was created by Ed Herron and does not count as their creation.
The Fighting American, other then having a really terrible costume is a copy of their Captain America with a satire twist. Nothing special in this character. Also the name is insulting to Americans. It assumes that Americans know only how to fight and think with their fists.
Overall Jack Kirby did much better with Stan Lee as a co-creator making lasting characters.
