Skyworld

Skyworld (, Skyworld) is a stage from the series in Super Smash Bros. Brawl,, and Super Smash Bros. Ultimate.

In Ultimate, is fought here for his unlocking battle.

Stage overview
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 a new stylized 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 and, 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.

Hazards Off
With stage hazards turned off in Ultimate, the stone platforms cannot be destroyed, and the moving platform underneath the stage does not appear.

Origin
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.

Tournament legality
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.

Glitches
A few glitches can occur on Skyworld:
 * One of them concerns . If the player plays as him, breaks the middle section of the main platform, and walks towards one of the platforms on either side of the new empty space, the player will drop through the cloud, as if they had smashed the Control Stick down. However, even if he just walks towards either platform, he will still drop through.
 * Another can be performed on this stage with . When using his side special, Drill Rush, aiming up into a breakable platform causes Meta Knight to appear above the platform once the move has been finished.
 * Another one involves a Hothead. If the left side of the highest platform is destroyed, the Hothead will rapidly move back and forth on the right side's top left corner while it circles clockwise.

Trivia

 * Ironically, 's Final Smash in Brawl, Palutena's Army, is hindered in its effectiveness when used on this stage. The Centurions hit the breakable stone platforms and are knocked out of flight, allowing characters with a fast enough spot dodge to completely dodge the attack.
 * In the Super Smash Bros. for Wii U 50-Fact Extravaganza, this stage is mistakenly labeled as part of the universe, but it is correctly labelled as part of the  universe in the "50 Must-See Things" version. In this case, it may have been confused with Skyloft, which is part of the Zelda universe.
 * One of the floating islands in the background features a temple with a Palutena statue. This statue is modeled after her artwork from the first Kid Icarus game.
 * The game logo for this stage on the stage selection screen has been different in every game it has appeared in: in Brawl, the logo was a modified Kid Icarus: Of Myth and Monsters logo; in Smash for Wii U, it was a modified Kid Icarus: Uprising logo; and in Ultimate, the logo was taken from the original American Kid Icarus box art.
 * In Ultimate, Lugia cannot be summoned from a Poké Ball on this stage.
 * is unable to destroy the breakable platforms with his down tilt or down smash.
 * picks up wool blocks instead of dirt blocks on this stage.
