Sky Pillar

Sky Pillar (空の柱) is an unlockable stage in Super Smash Flash 2 that hails from the  series. It was shown on the Day 1 stream at Super Smash Con 2019 along with Lucario, and is based off of the tower of the same name that originally appeared in Pokémon Ruby and Sapphire.

Layout
Sky Pillar consists of one large, towering pillar with four platforms, with one at the very top of the pillar, one at the bottom, and two on each side in-between these platforms. In the middle of these two platforms is a large wall that extends to the platforms, making them partially hard platforms that cannot be passed through. With hazards on, Rayquaza will occasionally across the top or bottom of the stage from the left or right side, dealing 26% damage and decent knockback to any player in its path. A strong gust of wind accompanies Rayquaza, pushing players. Before flying across the stage, it flies across the background, and a warning sign appears showing which side of the wall in the middle to stand by in order to avoid being hit by Rayquaza and swept away by the wind.

Music

 * The main music track is the self-titled Sky Pillar, an upbeat rock remix of the theme that plays inside the Sky Pillar in Pokémon Ruby, Sapphire, and Emerald.
 * The alternate music track is Sky Tower, a dramatic remix of the theme that plays inside the Sky Tower in Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team.

Tournament legality
Sky Pillar is banned in competitive play. It is an overly large stage with an uneven platform layout. The bottom level of the tower makes many infinites or chaingrabs / chainthrows possible.

Origin
The Sky Pillar is a location that originally appeared in Pokémon Ruby and Sapphire, and reappeared in Pokémon Emerald, Pokémon Omega Ruby and Alpha Sapphire. The tower is located in Route 131, though access to it is blocked off until the player enters the Hall of Fame in the Generation III games, or until Wallace removes the seal during the Delta Episode in their Generation VI remakes. The Sky Pillar is where the Legendary Pokémon, Rayquaza, resides at the very top.

Trivia

 * Rayquaza's attack resembles its dash attack during The Subspace Emissary as a Boss and as a Stage Hazard in Kalos Pokemon League 's Dragonmark Chamber, the latter being more similar to its function in SSF2.
