Solid Snake wasn't enough for Super Smash Bros. Brawl's star-studied roster; a second Metal Gear Solid character, the uni-eyed Grey Fox has joined the fight! But unfortunately you won't be able to play as him...
Grey Fox makes his Smash Bros. Appearance as an assist trophy, which help (or hurt) the player that activates them but aren't playable characters. In this case Grey Fox turns up and does his ninja thing on whoever happens to be in his way (he did chin a Metal Gear Rex after all) and look pretty damn hard in the process.
For the fighting MS fans will have to stick with Snake then, but at least it raises the chances that there are more non-Nintendo characters left to see...
