World of Trophies

The World of Trophies (referred to as "This World" in Smash Bros. DOJO!! and on trophy descriptions) is the primary world of the Subspace Emissary mode of Super Smash Bros. Brawl. In this world, trophies of video game characters fight one another for sport, though it is unclear whether these trophies are the actual characters, as the Subspace Emissary shows them to react in the same way as their counterparts. The characters in the world do nothing but fighting. Aside from the stages in the world is made up of a large stadium, a forest, a large grassy land, a jungle, mountains, a large lake, a deserted zoo, King Dedede's Castle, a swamp, a desert (which also includes a large castle), glacial mountain, some ruins and a large floating island with a secret base.

History
Once many, many years ago, the Ancient Minister and all of the other R.O.B.s lived on the Floating Island of the Ancients. But Tabuu decided to invade the island and all the other robots were taken hostage on his orders. He converted the island into a Subspace Bomb Factory and told the R.O.B.s to get to work on making them, except for the Ancient Minister, who was told to go around and place Subspace Bombs on various parts of the World of Trophies, drawing them into Subspace.
