In honor of America's birthday, today I put my finger on the scale and went with the original Cap himself (http://marvel.wikia.com/wiki/Steven_Rogers_(Earth-616)).
Not gonna fight with you on this one, that's close enough.
So everyone knows the basic story, Nazis bad, American program to produce ubermenches good. Dude punches Hitler, gets frozen, now it's the sixties.
Wait. So frozen or not Steve has aged 49 years at a minimum post ice. Per the wiki Steve was born in 1920 and changed in 1941. There's no info on when exactly he was frozen though so let's say it was immediately after he got super-serumed, so he was 21. So apparently now he's 70. I know, Marvel's timeline is stretchy, so they probably just move up his wake up date as necessary to keep him from being a septuagenarian.
Generally outside the movies Cap is a "street level" hero. He's basically the ideal human, so while strong, he's not exactly up to the level of cosmic types like Thor or even Iron Man.
But today we're gonna focus on Cap's greatest foes!
No, not Red Skull. Seriously, NOW you're on point?
You're just taunting me now, no not Zemo either.
I think we'd be remiss not to open with his epic fight against Frankenstein's monster.
(you know what he looks like. I don't wanna risk it)
I mean Frankenstein literally stitched a human being together with his bare hands then woke it up with electricity, ON THE FIRST TRY. If it's that flippin' easy to bring people back it neatly explains how much of joke death is.
Anyway, the Nazis thought Frankie M would be a solid ally, presumably because in this universe they never made the movie version. Actually do you think Mary Shelley even exists on Earth 616? Google seems noncommittal on the subject.
So the monster basically immediately turns on them and Cap is also there? So I guess that counts as a win for Steve.
Among Cap's enemies notably is Fang, a Japanese man who later died in one of the atomic blasts that ended WWII and "became one with the Everwraith". A being whose nature is summed up pretty well by the fact that their gender is mentioned on the wiki as "Gestalt".
Ok, so apparently it's the "astral embodiment of all the people that died during the nuclear attacks to Hiroshima and Nagasaki at the end of World War II" Yikes. I mean, fair enough really. Less said about Cap fighting the Japanese the better though. I am not delving further into that cringy corner of the wiki for any holiday.
On the other end of the insanity spectrum from disgusting racism we have the Cap villain The Butterfly (http://marvel.wikia.com/wiki/Armand_Vitrioli_(Earth-616)).
Honestly the actual guy is not significantly more scary.
The most interesting thing about the Butterfly besides the fact they pretty much immeidately die and that there are like 12 more butterflies in the marvel universe is that he has a henchman named Lenny who is not very smart and very strong and yes obviously he's straight up stolen from "Of Mice and Men" and now I want to know is Steinbeck a thing in the 616? He was even alive at the time. Does the 616 have any authors at all?
Finally, in 1974 Steve faced his greatest foe of all time.
Not Elvis (though he verifiably DOES exist in the 616 due to a comic starring the Beatles, Queen Elizabeth, and Peter Sellers no less).
Not only does Cap find out Nixon is the leader of a Secret Empire (since being the leader of the free world wasn't enough apparently), he actually ends up shooting himself when he's found out. The actual guy died in the 90's but in the 616 he dies in 1974 I guess (though it was all covered up with a double, natch). In the wiki it just says it was a "a high-ranking government official" but the writer of the comic confirmed that it was meant to be Nixon. This was BEFORE the dude actually resigned in the real world, incidentally, so I guess it makes sense they might have wanted to be slightly coy about having a sitting president off himself.
...
Anyway! Happy 4th of July!
Yay America!
OH! If you have a solid cheese themed comic pun leave it in a comment below. I got .5 steem dollars in it for ya if I use it.
