Spear Pillar

Spear Pillar (, Mt. Tengan Spear Pillar) is a series stage in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.

Lucario is fought here when being unlocked, and is also fought here in its unlocking battle in Ultimate.

Overview
Spear Pillar consists of an upper solid platform and a cave beneath it. The cave can act as an effective cave of life, as it is long and narrow. Both the top ground and the cave have grabbable edges at their sides.

Above the upper ground are two soft platforms, one on the left and one on the right, spaced symmetrically apart. These platforms move up and down nearly constantly, only stopping for a brief, random amount of time at their lowest and highest points.

In the background on the top ground is a large pedestal. After a random amount of time (~20 seconds), Dialga, Palkia, or Cresselia will appear atop the pedestal in a lightning strike, followed by a flash of light and cloud of smoke in Brawl. The Pokémon will stay for a random amount of time (~25 seconds), while performing various actions at random intervals (~7 seconds). Afterwards, they will leave in a flash of light and the cycle repeats.

In Brawl, only one of the three Legendary Pokémon can appear per match, determined randomly when the stage is selected. In Ultimate, any of the three Legendary Pokémon can appear, determined randomly each time.

The stage and background is tinted based on the Pokémon, with Dialga being blue, Palkia being pink, and Cresselia being the same as Dialga's blue in Brawl or the default green in Ultimate. In Brawl, the tint is present at all times, indicating which will appear later on. In Ultimate, the tinting only appears when the Pokémon appears and two seconds prior.

The, , , and , can randomly appear in the background on the upper level, and will leave after a moment. Any of them can appear throughout a match, but only one can appear at a time. Uxie and Azelf leave the stage by simply vanishing, but Mesprit leaves by flying off-screen to the left or right. These Pokémon do not have any gameplay effect, being only aesthetic in function, and their presence does not affect Dialga, Palkia, or Cresselia.

Dialga and Palkia
There are four actions that both Dialga and Palkia are able to cause.
 * Tilting the screen by a random amount (between 10 and 30 degrees) to the left or right. The effect is only visual; flat surfaces don't become slopes, for example.
 * Causing an earthquake, breaking either the left, right, or middle third of the upper ground. This creates a more open route between the two floors. After a while, the broken terrain is rebuilt.
 * Firing a laser beam. The laser beam deals 1% every 2 frames for 42 frames in Brawl and 41 frames in Ultimate and has a launcher on frame 43 that deals 5%, dealing a up to 27% and 26% respectively. It can be shielded and, in Ultimate, reflected or absorbed. It is colored blue when used by Dialga and pink when used by Palkia.
 * When fired vertically, the laser beam will cover either the left, right, or middle third of the stage and go through both floors. In Ultimate, the laser beam will break the third of the upper ground that it is fired through.
 * When fired horizontally, the laser beam goes through the cave area.

Dialga
Dialga has two actions of its own, in addition to the four it shares with Palkia.
 * Using to slow down the passage of time, similarly to the Timer item. This stacks with other time-altering effects. In Ultimate, the background is changed to consist of blue ripples, the same background used by the Timer.
 * Roaring for a moment, then jumping onto the stage and attacking by using Roar of Time on nearby players, dealing 25% damage with strong upwards knockback.

Palkia
Palkia has three actions of its own, in addition to the four it shares with Dialga.
 * Halving gravity and all fighters' weights. In Ultimate, the background is changed to consist of blue swirls.
 * Mirroring the screen, such that pressing right causes a character to appear to move to the left, as well as having right-handed characters appear left-handed and vice versa.
 * Using to rotate the screen at a 180 degree angle, causing it to appear upside-down.

Cresselia
Cresselia has two attacks and doesn't share any actions with Dialga or Palkia. Both attacks are smaller in Ultimate than in Brawl.
 * Throwing a single crescent of energy that swoops across either the upper ground or the cave, like a boomerang. Deals 20% damage.
 * Throwing a series of energy crescents across the stage in straight lines from its position. Deals 15% damage.

Ω form and Battlefield form
In Super Smash Bros. Ultimate, the design of the main platform of the Ω form and Battlefield form is based on the top portion of the normal form, and it is resized and reshaped to match and, respectively. The three soft platforms of the Battlefield form are based on the soft platforms of the normal form. No Pokémon appear on these forms.

Hazards Off
With stage hazards turned off in Ultimate, the two soft platforms do not move, remaining fixed at their halfway point. Dialga, Palkia, and Cresselia can still appear, but they never perform any actions.

Origin
This stage is based on Spear Pillar from Pokémon Diamond, Pearl, and Platinum, which is situated at the peak of in the  region. It is the present-day ruins of the.

Spear Pillar is the location of the two Dialga and Palkia. , a criminal organization which operates in Sinnoh, travels to Spear Pillar to awaken Dialga/Palkia and bind them by a created from the crystals of the, Uxie, Mesprit and Azelf. Team Galactic's goal is to use the Legendary Pokémon's power to recreate the universe with, the Galactic Boss, as king and deity.

The player character travels up to Spear Pillar, where they impede Team Galactic's plan to control the Legendary Pokémon by defeating Cyrus. Upon defeat, Team Galactic retreats and the player has the chance to capture either Dialga, Palkia, or Giratina. Arceus also appears and can be captured there via a downloadable event that was however never distributed in public.

Despite appearing on this stage, Cresselia has no connection to Spear Pillar in the Pokémon games.

Tournament legality
This stage is universally banned in mainstream tournaments due to the highly disruptive effect of the Pokémon's effects - especially Palkia's which alter the players' controls - which activate randomly and suddenly. The bottom cavern of the stage also acts as a large cave of life, prolonging matches and promoting stalling. The overall stage design with the separated top and bottom areas can allow for circle camping as well (though Dialga or Palkia can potentially break this camping by breaking part of the upper ground (suddenly creating an interception route before the camping player can react) or firing a laser through the cave (cutting off the camper's ability to run away). In Super Smash Bros. Ultimate, with the stage hazards off, it is still banned due to the caves of life, despite Dialga and Palkia not appearing.

General

 * During the screen zoom from Sudden Death and Super Sudden Death, the screen will not tilt or flip upside down when Dialga and Palkia attempt to do so.
 * Pausing the game while a screen flip or tilt is active will cause it to take effect. However, it won't change back again when the effect is supposed to wear off, and will remain tilted or flipped even after Dialga or Palkia leave. Opening the camera will fix this.
 * Hieroglyphic drawings of Dialga and Palkia can be seen on this stage, including on the two soft platforms. These reference the same drawings seen outside the Celestic Ruins in.
 * The cave underneath the main platform resembles the, with crystals partially burrowed in the floor and walls like in the Underground.
 * When the stage is rotated or mirrored, even the pause screen is affected by the switch.
 * Mesprit is the only Pokémon to fly off stage, possibly referencing the fact that it is a.
 * If the camera is moved so it is possible to look near the back of the stage, what looks like a meteorite can be seen sitting near a tree. This may be a homage to the Adamant and Lustrous Orbs, which, in the games, are found behind Dialga and Palkia respectively.
 * If Olimar uses his Final Smash, End of Day, when the screen is turned upside-down, the Bulborbs still appear at the bottom of the screen.

Super Smash Bros. Ultimate

 * In Spirit Battles, when defeating the opponent while Palkia's light gravity is in effect, the light gravity will carry over into the "Free the Spirit!" sequence, and the fighter used will float down more slowly to grab the laser.
 * Using camera controls it is possible to view inside the ground of the main platform, where one can see the two sloped surfaces that are uncovered when either Palkia or Dialga break the center of the main platform.
 * Prior to version, there was a glitch on this stage in Training Mode: if the session was reset while the screen had been mirrored by Palkia, the gameplay view would return to normal, but the UI and name-tags remained mirrored, with name-tags following the position the player would be at if the screen were still mirrored. The glitch remained for the session until Palkia mirrored the screen again and the effect finished without the session being reset.
 * Palkia would later become a Poké Ball Pokémon in Super Smash Bros. 4, using Spacial Rend to cause the same upside-down effect it can cause on this stage. Palkia returns as a Poké Ball Pokémon in Ultimate, but it cannot appear on this stage, and is not available for selection in Training Mode (except for when the Battlefield or Omega form is selected).
 * Additionally, due to the cramped quarters of the lower cave, Alolan Exeggutor cannot be summoned on this stage.
 * The following Assist Trophies can only appear on the Battlefield and Omega forms of this stage: Skull Kid (due to his powers interfering with Dialga and Palkia's powers), Starman, Devil, Isaac, and Rathalos. The Moon and Nikki cannot appear on this stage at all, likely due to the dark background. The Timer also can only appear on the stage's Battlefield and Omega forms.
