Super Smash Bros. Brawl/Stages

Some of the things on this page are currently opinions, not facts.

Halberd
The Halberd, Meta Knight's battleship, is one of the few levels that Nintendo has actually confirmed. The level has the players battling on a floating platform in front of the Halberd.

Pokemon Stadium
This is the only other "confirmed" level by Nintendo. The pokemon stadium is very similar to the Super Smash Bros. Melee level. While the backround has been changed a bit, it still has two small floating platforms over the giant pokeball. All the Below Levels have Not Been Verified By Nintendo

Kid Icarus
On the newest Nintendo video on Super Smash Bros. Dojo, it shows the characters fighting on a level in the sky. This looks very similar to what they would probably make into a Kid Icarus level.
