The stage consists of four floating cloud platforms, arranged in a pattern somewhat resembling Battlefield, which each have sets of yellow stone platforms resting on them. The right-most platform is connected to the bottom one by a chain, and can raise and move right, or fall and move left. An additional stone platform occasionally appears, moving horizontally below the stage, from one end of the screen to the other.
All of the stone platforms are solid and cannot be passed through, and there are grabbable edges on the far ends of each set. All of them except for the one that moves underneath the stage can be individually attacked, showing visible cracks after taking some damage, and will break if they are damaged enough. In addition to player attacks, the platforms can be damaged and broken by items such as Bob-ombs, Hammers, and Assist Trophy or Poké Ball summons.
If a platform is broken, the cloud underneath it will serve as the new platform. The clouds act as soft platforms. Due to being made of the Cloud terrain, players can pass through these clouds from above in powerful knockback from a meteor smash or stage spike. The clouds do not have any grabbable edges. After a certain amount of time, the breakable stone platforms will regenerate.
If the stone platforms at the edges are broken, this can hinder players' recoveries, as the clouds do not have grabbable edges on them. The moving platform below the stage can boost recovery, by giving players ground where there is normally none.
In Ultimate, there are now grabbable edges on the sides of the stone platforms when an adjacent stone platform is broken. Most of the clouds no longer use Cloud terrain, and so players cannot be launched downwards through them. The clouds that still use Cloud terrain are the left-most cloud and the right-most, chained cloud. Additionally, the chained cloud's stone platform is no longer solid underneath, meaning that it can be passed through from underneath, preventing stage spikes when knocked towards the platform from below.
Ω forms and Battlefield form
In Super Smash Bros. for Wii U, the Ω form features only one flat yellow platform. Unlike the normal form, this platform is unbreakable.
In Super Smash Bros. Ultimate, the Ω form and Battlefield form are similar to SSB4's Ω form; however, the main platform is resized and reshaped to match Final Destination and Battlefield, respectively, and the main stage platform resembles the platform designs of the normal form. The three soft platforms of the Battlefield form resemble the yellow stone platforms of the normal form.
With stage hazards turned off in Ultimate, the stone platforms cannot be destroyed, and the moving platform underneath the stage does not appear.
Skyworld is the third level of Kid Icarus and its sequel Kid Icarus: Of Myths and Monsters. The majority of the elements in this stage are original to Smash and have no origin, with a few exceptions: In Kid Icarus, some of Skyworld's platforms are stone, and some are clouds. Throughout the level, there are columns that go through the cloud platforms and support some of the stone platforms. In this stage, the main platforms are made out of clouds with destructible stone platforms on top. In the background, numerous columns can be seen. Kid Icarus also includes floating platforms that go from one side of the level to the other, which Pit can use to his advantage to reach his destination. In Smash, there are times where a floating platform towards the bottom of the stage will go from the left side of the stage to the right. A temple, likely referencing the Palace of the Sky, can be seen in the background on the left side; it also includes a statue of Palutena, more closely resembling her original design than her Brawl redesign.
The stage is banned in most competitive tournaments, as the unbroken platforms can create a cave of life, allowing for teching players to survive to unusually high damage percentages. Additionally, the unique platforms cause an over-reliance on stage spikes.
A few glitches can occur on Skyworld:
