Solid Snake

Solid Snake is a soldier and spy, who appears in the Metal Gear games created by Kojima.

He is one of the first (of possibly more) 3rd Party Characters to appear in Super Smash Bros. Brawl for the Nintendo Wii.

His appearance in the trailer was a surprise to fans primarily because third-party characters (those not belonging to Nintendo or any of its second parties) had never been present in the series thus far and because most of the Metal Gear Solid games are rated "M". He appears in Brawl as he did in MGS2. Snake's moves were not showcased in the trailer, but Brawl's game developer Masahiro Sakurai has stated on his site that Snake will fight hand-to-hand and use a variety of explosives, rather than rely on firearms. Snake's symbol is that of the organization FOX from Metal Gear Solid 3.
