The Pokémon Stadium 2 stage returns from Super Smash Bros. Brawl and brings four different stages on. As with most stages, knockouts are done on all 4 sides of the screen. The stage has 2 platforms at a higher level than the main stage for combat to take place on. Randomly after a small time of battling, the stage will change, giving you small warning and telling you which it will change into just before doing it.

The first we will cover is the Electric stage. This stage has two extra platforms, one higher than another a and a slopped main platform. Occassionally Pokémon such as Electivire will appear to power up the platforms in order to move them.
The Flying stage has no extra platforms that you can battle upon, but it does however lower the gravity making it easier for you to jump a lot higher than you should be able to. Pokémon such as Skarmory, Hoppip and Drifloon adorn the stage during this mode.

The Ground stage has various areas in which you can battle, set in what appears to be an excavation site for fossils. To the left you have a small area with a platform up above, segregated from the rest by a small mound. On the right is the excavation of a mountainous area with an extra 2 levels of platforms for you to battle upon. Dugtrio & Cubone are positioned on this stage
The Ice stage has two slanted extra platforms, raised up from the main level. Every walkable piece of terrain in this level is more slippery than the others meaning you have to be very careful with your footing wehen battling else you may just slide off the edge
