No, I'm fairly certain there are plenty
your type who think Snake doesn't fit in Smash just like how I think you saying he's "the most generic character" and "generic militaristic guy with a bunch of guns" is a
presumptuous statement.
Based on my digital travels, it has come to my notice that those who view Snake as this "generic" character have a reputation for being
presumptuous about the entirety of the Metal Gear franchise and Snake as a whole -- probably due to those people actually never having played the games thoroughly, if at all. Snake's external appearance may seem whatever the
common traveler perceives him to be, but Snake's psyche is what truly
transcends his looks. He's one of
three clones (since a militaristic man who possesses this sole trait is considered to be a repulsive trope in all forms of media, evidently to
your type) who's tormented with the fact that he isn't his own person (and will never be, in an omnipresent sense), but is instead the genetic embodiment of what he absolutely detests -- Big Boss.
Based on your
assumption that Snake is "generic", I'm assuming you extended your thesis by
conjuring up this idea that he possesses "a bunch of guns" canonically and goes around in cutscenes
annihilating every soul that crosses his "generic" path, which is riddled with mechanical bipedal nukes, the supernatural, a narrative-based obsession with breaking the fourth wall, and a character whose personality consists of explosive diarrhea. Contrary to popular belief, throughout Solid 1, 2, and 4, Solid Snake primarily utilizes tranquilizers in his missions and in cutscenes. If not that, he resorts to using CQC (implemented in his moveset because he's wholly capable of fighting without the aid of "a bunch of guns" and also ultimately characterizes his persona) and dispatching the nefarious antagonists by utilizing those
non-lethal means. It's entirely clear that even the developers put an emphasis of
non-lethal methods over
morbid intentions and reward the players for doing so (such as unlocking costumes in boss fights for knocking them out), as it is duly noted
here,
here,
here, and even makes a subtle commentary on the matter
here.
Claiming how Snake uses guns in Brawl is rather untrue, as I doubt an RPG, mortar, C4, and mines would fall under that category. Snake utilizes explosives in a tactical manner as opposed to using bullet-based weaponry,
unless you only used him when he was holding a super scope or a ray gun. (I mean at this point he's just mocking me...)
What makes Snake so
unique in Brawl is the fact (as previously noted by LIQUID12A) that he hails from a
widely celebrated and
complex series that
revolutionized narratives in gaming,
making the medium salvaged and taken much more seriously as opposed to the trivial assumption made by outsiders that games are to make its subjects' minds numb with monotonous responses, devoid of any thought-provoking substance.
(I mean look here! Snake saved gaming!) Snake's tone in Brawl proved to be a juxtaposition to the more light-hearted characters and it's this
stark contrast that makes his inclusion all
worth the while -- something of this magnitude has never been done before. His
unprecedented presence in Smash introduced many people to the Metal Gear series and made his fans play Smash; Snake in Brawl was, and continues to be, a conduit that
benefits both parties instead of harming them.
