The World of Trophies is the world that Super Smash Bros. Brawl's Subspace Emissary took place in, and various fanon Smash games have storylines set in this world. The world is rather simple during Brawl and is not given much description, but in this world, trophies of characters from multiple Nintendo franchises live.
In Super Smash Bros. Zero, the World of Trophies is expanded and is shown to be much larger; it contains multiple islands, and the mainland from the first game becomes known by the name of Alpha. All of the islands are named after letters from the Greek alphabet, except for Zero Island which is named after the number, as well as the title of the game. During the course of the game, Alpha is consumed by Subspace and some of the others are as well.
