Nominate Olimar for a Snake counter.
Jeff mentioned him, and Oli, next to ROB, has been my toughest matchup thus far.
Snake's weight works against him here, since Olimar has quite the juggling ability on the heavy characters. Right off the bat, at 0%, he can do an inescapable up throw to running upsmash (chasing your DI). Quick 25-30% damage depending on the pikmin. He can do this at least once more, IIRC, until you're able to DI far enough/air dodge out of it. At mid percents he can dthrow to fair, though this can be air dodged, but it still allows him to pop snake up where he's most vulnerable. Oli's uair, nair, and utilt can also juggle well, and both have an an extended hit box. At low percents he can combo from an utilt or falling uair/nair with a few jabs and easily re-grab or smash. Oli is surprisingly speedy as well, allowing him to follow up with the aerial punishment.
Olimar's grab range is excellent, especially with the blue pikmin. Speaking of which, bthrow with the blue pikmin is tremendously strong even against heavyweights like Snake. I've gotten kills (and been killed) w/ fresh blue pikmin bthrow from mid stage, and otherwise it easily sets up for an edgeguard.
Speaking of Pikmin, the little devils provide, for the most part, a meat shield against Snake's grenades/nikita if he keeps them thrown. They set off mines easily too. If you don't approach, the latched pikmin obviously will rack up damage. You can swipe them off with attacks, and they can die from the explosives (except Reds), but it takes only a moment to replenish the minions, and smart Oli's won't waste all their pikmin in one go.
Finally, there's Olimars smashes and aerials. All disjointed hitboxes, all come out rather quickly.. (the yellow pikmin have an extended hitbox, works well for fair and bair, but that's beside the point). Because of this, he's reasonably hard to punish even with a power shield since he'll often be out of range. The fsmash can cycle quickly, deterring an attempt to attack in between the intervals. Dsmash hits both sides instantaneously, and is a quick gtfo move. His uair's multiple hits catch you out of an airdodge coming from above. His dair can meteor spike if you come from below/low horizontal angle. His fair and bair are good for spacing game, especially considering the fact that Oli can SH, throw a pikmin and do a fair both before landing. Not to mention all his smashes pack a punch.
This combination of grab combos, juggling, strong aerials and smashes, a more then decent camping game, and deterrent from projectiles, make him a great contender against Snake. Oli just needs to use his attributes to rack up damage and finish with a well spaced/punishing smash or bthrow.
Of course we can't ignore the downsides: certainly there is Olimar's gimpable recovery and his light weight, and the fact that an Olimar without pikmin is like a fat kid in dodgeball. I'm not sure if that's enough to outweigh his pros though.
