Spear Pillar

Spear Pillar made its debut in Pokémon Diamond and Pearl where Dialga and/or Palkia can be captured. It is set in the Sinnoh region.

This stage is banned in many tournaments due to large number of hazards that Palkia, Dialga, and Cresselia can create that can result in a turning tide for a lucky player (particularly when Palkia flips the stage sideways or turns it upside down).

Origin
Spear Pillar debuts in Pokémon Diamond & Pearl, and can be found at the top of Mt. Coronet. In this game, the two legendary Pokémon Palkia and Dialga can be found at Spear Pillar. Team Galactic, the antagonists of Diamond & Pearl, travel up to Spear Pillar and awaken Dialga/Palkia, bound by a crystalline Red Chain, in order to destroy the world and create a new universe where the Galactic Boss, Cyrus, is deity and king. Dawn/Lucas travel up to Spear Pillar, where they impede Team Galactic's plan to control the legendary Pokémon by defeating their boss as his plan fails. Upon defeat, Team Galactic retreats and the player has the opportunity to catch Dialga/Palkia. High above the Spear Pillar is the Hall of Origin, where the omnipotent legendary Pokémon Arceus resides.

In the Super Smash Bros. series
Spear Pillar is a playable stage in Super Smash Bros. Brawl, and Dialga, Palkia, and Cresselia make cameo appearances in the background to devastate the players. It is a destructible stage, which also features a cave underneath the surface which players can brawl in. Spear Pillar can be unlocked by completing Event 25.

Stage Elements
After the first few seconds in battle, Dialga, Palkia, or Cresselia will show up in the background of the stage. The player can tell what Pokémon will appear by the color of the stage. The Pokémon will perform different attacks when they appear. Dialga will shoot a vertical beam covering 1/3 of the stage, Palkia will fire a horizontal or vertical beam covering the bottom level or 1/3 of the stage respectivly and can lower gravity making you jump higher and fall slower, and Dialga and Palkia will both create abnormalities within the stage's dimensions, such as Roar of Time, which can slow down the time of the stage temporarily, and Spacial Rend, which can tilt the stage, flip it sideways, or turn it upside-down. They can also destroy part of the floor. On occasion, Dialga will also leap off of his pedestal and attack players (it can be predicted by it roaring with no effect or change), it will sometimes tilt the stage, but not as much as Palkia. Cresselia is quite different, having only 2 attacks, both probably based on "psycho cut". One affects only the top layer, and is successive blades fired from one central area above Cresselia. The other is a boomerang blade that traverses all of the stage in different ways. She is the only one of the three who does not distort the stage in any fashion. After a while, the legendary Pokémon will vanish in a puff of smoke, leaving the brawl to continue normally for a short time. Soon enough, it will return exactly the same as before. Only one Pokémon warps in per fight -- they cannot switch between themselves in the middle of a match.

Uxie, Azelf, and Mesprit, also make appearances here. However, these Pokémon only sit and watch; they do not conduct any other experiments on the stage.

Trivia

 * In the Pokémon RPGs, Cresselia has no connection to Spear Pillar at all, other than Dialga and Palkia, the one who would have the most connection would be Giratina (Giratina is the third counterpart to Dialga and Palkia, but is not connected to Spear Pillar, although, in Platinum, it shows Giratina atop Spear Pillar) or Arceus (The opposite - Arceus lives at Spear Pillar, but is not connected to the Dragons, but Arceus did create them to help shape the world. Not only that, Arceus was not to be officially announced yet.).
 * Unlike other stages, such as Mushroomy Kingdom which identify the specific game it hails from, Spear Pillar is only given the setting Pokémon and not Pokémon Pearl or Pokémon Diamond. The same goes with Port Town Aero Dive.
 * When Olimar uses its final smash when the stage is turned upside down by Palkia's Spacial Rend, the Bulborbs still appear at the bottom of the screen.
 * The cave underneath the main platform strongly resembles the Sinnoh Underground, with crystals (called spheres in the Pokémon games) partially burrowed in the floor and walls. In Pokémon Diamond/Pearl/Platinum, the Sinnoh Underground can be accessed from anywhere outdoors in Sinnoh, including Spear Pillar.
 * When Palkia reverses the controls, even the pause screen is affected by the switch.
 * If one were to move the camera and look near the back of the stage, one could see what looks like a meteorite sitting near a tree. This may be a homage to the Adamant and Lustous Orbs, which, in the games, are found behind Dialga or Palkia.
 * In this stage, Dialga & Palkia both use Hyper Beam. However, in the Pokemon Games, they can only learn it through TM.
 * If you pause the game and close up on the vertically moving platforms, the platform on the left shows a heiroglyphic drawing of Dialga and Palkia on the other side.
