Shadow Moses Island

Shadow Moses Island is a default stage in the game Super Smash Bros. Brawl, and returns in Super Smash Bros. Ultimate. It is from the first Metal Gear Solid game, and acts as Solid Snake's home stage. The walls on either side can be destroyed with normal attacks, allowing for players to be launched out of the screen from the sides and lose a life.

In Super Smash Bros. Ultimate, its Battlefield and Ω forms take place above the heliport on a large platform that resembles the bottom platform of the original stage, while the original stage itself can be seen in the background.

If 15 matches are played here in Super Smash Bros. Brawl, Snake will challenge the player on this stage. If he is defeated, he will be unlocked as a playable fighter. In Super Smash Bros. Ultimate, he is the 39th character unlocked through VS matches and can be the fifth character unlocked by playing Link's Classic Mode route. Both methods have him fought on Shadow Moses Island.

On this stage, Snake can use his codec to get information about his opponents from Super Smash Bros. Brawl, through a Codec Conversation from Otacon, the Colonel, Mei Ling and (if Falco is being faced) Slippy Toad. He can trigger these conversations with a taunt. They have no influence on the actual battle. While the stage and Snake himself are absent in Super Smash Bros. for Wii U, its concept is revisited for Pit's conversations with Palutena on Palutena's Temple. The codec conversations return in Super Smash Bros. Ultimate, though it is limited to Super Smash Bros. Brawl's roster and their reused conversations. Like Palutena's Guidance, they are disabled in the stage's Ω and Battlefield forms.

The Metal Gear RAY, Metal Gear REX or two GEKKO may appear in the background of the stage, but they do not affect gameplay. A spotlight also occasionally aims around the stage, and if it catches a player, an exclamation point appears above the player in a similar manner to the original Metal Gear Solid games, complete with the same sound effect. Like in the original games, this does not occur for Snake if he is hiding in his box for his taunt.

Trivia

 * Because of the Gekkos' appearance in the stage, Super Smash Bros. Brawl marks their first game appearance, due to Metal Gear Solid 4: Guns of the Patriots being released afterward.
