Pokémon Stadium 2 is a stage in the Wii video game Super Smash Bros. Brawl. At the beginning of the fight, the stage is similar to the original Pokémon Stadium stage in Super Smash Bros. Melee, though when the platform starts to transform, it'll turn into different environments.
The stage will shift into four different stages, each one having a core theme. These different formations include Ice, Electric, Ground, and Flying. Each different stage will feature uniqe Pokémon species.
Formations
Ice stage
This formation will make the entire stage slippery. New platforms will appear, which as expected are not only icy, though they're also sloped. While it's possible that Pokémon species will appear in the background, none have been seen in the revealed images. In the background you see a cabin which is covered in ice. Hidden inside the cabin is a real-life picture of a cat. Many fans speculate that the cat is Masahiro Sakurai's (the director of the game).
Ground stage
This formation will cause a large dirt slope and an odd looking buildingto appear. It seems to be a digging site, as shovles and bones are scattered on this stage. In the background, Dugtrio and Cubone have been seen. The mentioned building has two pass through platforms, with the upper one being smaller than the lower one.
Flying stage
This stage is just a single platform, though for whatever reason the gravity will change and all of the characters will be given dramatically boosted jumping abilities. In the background you'll see windmills, as well as Skarmory and Drifloon.
Electric stage
There are two conveyor belts that make it harder to fight. The Pokémon Electivire and Magnezone appear.
