Port Town Aero Dive
From the Super Mario Wiki
Port Town Aero Dive (Japanese ポートタウン エアロダイブ Pōtotaun Earodaibu, shortened to Port Town in European translations) is an F-Zero stage (coming form F-Zero GX) in Super Smash Bros. Brawl, acting as Captain Falcon's home stage. It is very similar to Mute City from Super Smash Bros. Melee, as the stage is merely a group of platforms hovering across an F-Zero race course at high speeds. Like Mute City, the platforms will eventually stop, forcing the players to fight on the race course, rather than the platforms. Occasionally, the platforms will hover off the track itself, but it will eventually come back to the track.
F-Zero Racers will sometimes drive past the stage while it's standing still, hitting the players with incredible force, just like in Mute City. However, unlike in Mute City, the F-Zero Racers on this stage can't be attacked, and they can easily KO at below 100% damage.
