This article/section contains information of a feature that is not confirmed to appear on any game or similar media. This means that the subject of has yet to be confirmed by an official source for the final build for said material.
Three platforms make the infrastructure of the stage along with a lower platform that can be used to aid a recovery. Palutena's Castle is in the background. In the Brawl version, the platforms would break, if they sustained enough damage. It is currently unknown if the platforms will break in Super Smash Flash 2.
An early version of Skyworld completely scrapped and never used in-game. A blue background variant existed.
As seen above, in v0.8a of the demo, a glitch will sometimes cause an inactive thumbnail representing Skyworld to appear on the stage selection screen which hints at this stage's possible inclusion in a future build of the game.
Skyworld is listed as DAT26 within version 0.9b's game files and contains "Title (Kid Icarus)" from Brawl as its music, but goes unused.
