Solid Snake

Solid Snake (real name David) is the main character of Konami's Metal Gear series of games. He is one of the results of the "Les Enfants Terribles" project, a government project to create clones of the renowned soldier "Big Boss", and is constantly given the mission of deprogramming the various versions of the bipedal nuclear-armed tank called Metal Gear. Solid Snake was the first third-party character to be confirmed for Super Smash Bros. Brawl, using his general appearance from Metal Gear Solid 2: Sons of Liberty, though also taking elements from Big Boss in Metal Gear Solid 3: Snake Eater, such as the facial hair and his alternate costumes based upon the camouflage suits. According to Masahiro Sakurai, Metal Gear series creator Hideo Kojima originally asked him to include Solid Snake in Super Smash Bros. Melee, but as the game was too far into development at that point he could not be included and was instead added into the next game. Like in the Metal Gear series at the time of release, Snake is voiced by Akio Ohtsuka in the Japanese version, and by David Hayter in the English version.

Snake fights using hand-to-hand combat and uses a variety of explosives. Snake's special moves are Hand Grenade, an explosive that can be thrown various distances, Remote Controlled Missile, a guided missile that rockets wherever it is aimed, Cypher, a flying security drone that flies Snake up, and C4, a sticky explosive that can be mounted on various surfaces. His Final Smash is Grenade Launcher, in which he jumps onto a helicopter and fires grenades on the stage.

By doing a split-second down taunt on Shadow Moses Island, Snake will contact one of several Metal Gear characters by codec to analyze the opponent, including Mei Ling, Otacon, Colonel Roy Campbell or Slippy Toad if the character being analyzed is Falco Lombardi.

The Subspace Emissary
Snake finds his way aboard the Halberd and starts looking around the area (his Cardboard Box was seen earlier in The Research Facility). When he hears a sound, Snake quickly hides in his box as Lucario and Meta Knight pass by him. However, Lucario suddenly stops, and using the Aura, sees through the box and sees Snake. He takes the box off him, and Snake is shocked. They were about to battle as soon as Lucario saw Primids coming with his Aura. Lucario then tells Snake to follow him and they form a party. Soon they reach a room in which there are two cages with the trophies of Peach and Zelda just after they see that the purple Shadow Bugs go to them and make dark versions of the two. The team fights the evil princesses and defeats them. The good Princesses are taken out of the cages they are kept in.

Meta Knight and Lucario leave and Snake tells the two girls to stay where they are. The princesses stand there wondering what to do, then Zelda turns into Sheik (reason for transformation is to ambush him and evade his order) and decides to follow Snake. Peach follows Sheik. They reach the top of the Halberd, where they meet up with Snake and get Fox McCloud to join the party. By then the three (Lucario, Meta Knight and Snake) guys went to the engine to find out that there are a lot of Mr. Game & Watch piloting the ship. Snake runs and throws them all out the window. Snake and the other two jump out the window, only to see Shadow Bugs create Duon. Falco Lombardi then comes in.

Snake, Lucario, Meta Knight, Peach, Zelda, Fox and Falco fight the monster and after defeat, they see a Mr. Game & Watch trophy. After Peach revives it, Mr. Game & Watch joins the party. Later, when the team encounters Tabuu, Snake and the rest are transformed into trophies. If Snake is rescued during the Great Maze, he'll join the team and help take on Tabuu.

Snake's codec

 * Snake: Colonel, it's me! I'm fighting myself!
 * Colonel: Snake, what's going on out there?! Could it be...? Has the "Les Enfants Terribles" project really come this far?!
 * Snake: It's more than that. He's got my moves, my gear... It's like looking in a mirror.
 * Colonel: Do you think they collected data on you and created another Snake...?
 * Snake: He's got the same build, too. Creepy. But his Sneaking Suit is a different color. And his tactics are slightly different.
 * Colonel: Interesting. So even if you're evenly matched in power, your fighting styles will make a big difference. You've faced tougher odds in the past, Snake. Don't let this impostor beat you!!

Trivia

 * In the codec call about Yoshi, Snake suggests capturing him to "see what he tastes like," Naked Snake's typical response to animal life in Metal Gear Solid 3.
 * When Snake talks about Sonic the Hedgehog over his codec, he mentions that he dislikes Sonic, giving no specific reason as to why. This may be a reference to hedgehogs being common snake predators in real life, as their spikes prevent the snake from being able to eat it. In the Japanese version of the game however, the codec call can be assumed as a joke, because Snake's Japanese voice actor, Akio Ōtsuka, is the son of Dr. Eggman's Japanese voice actor, Chikao Ōtsuka.
 * Solid Snake is one of only two characters in the Super Smash Bros. series to come from an M-rated series, with the other character being Bayonetta, who is a downloadable character in Super Smash Bros. for Nintendo 3DS / Wii U.
 * Snake is referenced in Paper Mario: Color Splash: when in Fort Cobalt, a Toad is hiding in a box, saying he's being "stealthy."
