Stage transformation

A stage transformation is a feature that is used for certain stages starting in Super Smash Bros. Melee on. Stage transformations vary greatly in differences, with some stages changing minimally, while others will become noticeably different. Typically, transforming stages in the Super Smash Bros. series are banned from tournament play, depending on how drastically a transformation can affect a match.

A stage transition is a stage that changes similarly to a stage transformation, however, instead of changing, it simply moves along a determined layout, resetting back to the start as soon as it reaches the end. Like stage transformations, transitioning stages are typically banned from tournament play.

In Super Smash Bros. Melee

Stage	Games	Tranformation type	Notes
Big Blue		Scrolling	Goes forward on a race track on the Falcon Flyer. Players can also fight on top of the racer's cars and floating platforms that occasionally appear.
Brinstar Depths		Complete Transformation	As the players are fighting, Kraid will occasionally appear in the background, swiping at the stage with his claws. When hit, the stage will slowly spin either left or right, depending on which claw Kraid uses.
Great Bay		Platform Appearance	After a certain amount of time, the turtle will sink into the ocean, and will come back up some time later, occasionally facing a different direction. Additionally, Tingle's balloon acts as a platform, though if a player were to remain on it for too long, the balloon would pop.
Icicle Mountain		Scrolling	Transitions strictly upwards and downwards rather than forwards, a trait only this stage has in Melee. Features a wide variety of platforms to jump on. Topis and Polar Bears appear on this stage in Adventure Mode
Mute City		Cruise	This stage starts as a platform and floats along the track, occasionally dropping down on the road, leaving players vulnerable to the racers driving through.
Poké Floats		Scrolling	A stage that uses enlarged Pokémon as part of the layout, switching between ones such as Squirtle, Onix, and Unown.
Pokémon Stadium		Complete Transformation	There are five variations: Basic, Grass, Water, Fire, and Rock. One can determine which variation it will change into on the large screen in the background. The layout of the stage will depend on which variation is used. For example, the Water variation features a pond, a windmill that functions as a spinning platform, and two platforms to the right.
Princess Peach's Castle		Platform Appearance	At various points during a match, buttons will appear on the stage. If a player were to press it, platforms and "!" Blocks appear in varying colors, depending on the color of the button pressed.
Rainbow Cruise		Scrolling	Starting on a flying ship, it flies to a series of platforms that players must jump on, ultimately leading back to the ship.
Venom		Platform Appearance	While the stage layout itself does not change, the stage will fly through a cave, capable of causing launching players to bounce off of a ceiling or wall.

In Super Smash Bros. Brawl

Stage	Games	Tranformation type	Notes
Castle Siege		Complete Transformation	This stage has three different forms, transforming into the second form about 40 seconds into a match. The first form takes place on top of a kingdom, the second stage is in a throne room, with destructible statues functioning as platforms, and an underground level with a somewhat similar layout to Final Destination, before reverting back to the first form.
Delfino Plaza		Cruise	Much like Mute City in Melee, Delfino Plaza starts on a platform, floating across the Delfino Plaza and making occasional stops in the various areas. Unlike Mute City however, there are no stage hazards.
Flat Zone 2		Complete Transformation	This stage has four forms: Fire, Oil Panic, Lion, and Chef, all of which are based on the Game & Watch games that were released back in 1981.
Frigate Orpheon		Complete Transformation	Every so often, lights will flash and an alarm will sound, and the stage will flip upside down. This can become troublesome, as players can become disoriented by its sudden change and could cause them to self-destruct.
Halberd		Cruise	Starting as a floor with walkoff blast lines, the floor later opens and a platform rises out of it, then becoming similar to Mute City, until stopping on top of the Halberd, becoming a flat stage with a single platform above.
Luigi's Mansion		Complete Transformation	The mansion is completely destructible, divided into four sections. When all sections are destroyed, the stage then has a similar layout to Final Destination, before the stage rebuilds itself.
Mushroomy Kingdom		Scrolling	A recreation of World 1-1 from the original Super Mario Bros., albeit with a more aged and decayed design. "?" Blocks appear all over the stage, giving an item whenever jumps into the bottom of it in a similar vein to Mario in his game.

Summit		Scrolling	After a certain amount of time, the stage will break off and slide down a mountain into the sea, remaining there for some time until resetting back onto the top of the mountain.
WarioWare, Inc.		Complete Transformation	Around every 30 seconds, the door in the background opens and the players must play a Microgame. There are nine possible Microgames that can be played.

Woolly World		Scrolling	Starts in a hill area, with clouds and a rocket acting as platforms. After some time, the stage moves into the sky and the ground disappears, leaving only the rocket and clouds to stand on. It then transitions to a third area, coming down to the ground with toy blocks instead of a hill, and rises back up to the sky once more, then resetting to the first area.
Wrecking Crew		Complete Transformation	Like Luigi's Mansion, Wrecking Crew's layout is destructible, except with the use of the bombs that can be found around the stage.
