X-men: A team of mutants-people born with superpowers (although sometimes they don’t emerge until adolescence) who are possibly the next step in evolution for humanity. The team has gone through many incarnations throughout the years; from the original five students, to the more international “All-New, All-Different” team, to expanding in the 80’s and 90’s with various spin-off teams etc.
Like pretty much every other 60’s Marvel character, with a few exceptions (Iron Man, for one) the X-men’s initial explanation for their origin was radiation; a fear prevalent during the cold war; that the nuclear tests had altered human DNA, and that was passed off to offspring, giving them these powers.
Likewise, the origins of Metal Gear-as indicated in Metal Gear Solid III-are also rooted in the cold war, although MGSIII came out much, much later than X-men.
After the end of World War II, the world was split into two — East and West. This marked the beginning of the era called the Cold War.
And it’s also rooted in nukes. It’s revealed that Snake is sterile, the result of him being involved in the nuclear tests at Bikini Atol (Although in a roundabout way, he’s still able to have children-sort of-the Les Infant Terribles project). Volgin also fires a small nuclear missile-the Davy Crockett-fairly near Snake as well-and Metal Gear of course is a nuclear weapon itself.
Interestingly, both Metal Gear Solid 3 and the X-men movie, First Class provide alternate explanations for the Cuban Missile Crisis.
In Metal Gear Solid 3, it’s established that instead of the US dismantling their Turkey-based ICBMs, it was in fact the return of a defected rocket scientist, Sokolov, to the USSR. Sokolov would of course develop the Shagohod for Volgin, and this would lead to much of MGS3’s conflict.
In X-men: First class, it’s revealed that the crisis is in fact due to the machinations of the mutant Hellfire Club, who want to ignite the Cuban missile crisis to lead to nuclear war which would make fertile ground for new mutants, as well as leave them in charge.
The work of a secret group behind the scenes of world events in a way, does kind of have some similarities with Metal Gear’s concepts of the Patriots/Cipher, who are initially composed of the vets of Operation Snake Eater.
It should be noted that both MGS3 and First Class are also heavily rooted in the ‘style’ of the 60’s Bond films-X-men’s first class ending credits, for example, is pretty much heavily inspired by Dr.No’s opening.
Metal Gear Solid 3 is also heavily inspired by Bond, although in this case it’s more in the style of the later Connery films.
Next-They’re both the best they are at what they do….plus they smoke a lot.
