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 flash of light. The Pokémon will stay for a random amount of time (~25 seconds), while causing various effects on the battle 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 Pokémon can appear, determined randomly each time.
The Pokémon that will appear is indicated by a color tint on the stage and background. Dialga is signified by a blue tint, Palkia is signified by a pink tint, and Cresselia is signified by the same blue as Dialga (in Brawl) or the stage's default appearance (in Ultimate). In Brawl, the tint is present at all times, as only one Pokémon can appear for a given match; in Ultimate, the tint is green by default and only changes to the other colors when Dialga or Palkia are active.
The lake guardians, Mesprit, Uxie, and Azelf 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, Palkia, and Cresselia can each cause various different effects on the battle when they are present. All of the effects are temporary, with varying durations.
Dialga and Palkia
There are four effects that both Dialga and Palkia are able to cause:
Dialga has two effects of its own, in addition to the four it shares with Palkia:
Palkia has three effects of its own, in addition to the four it shares with Dialga:
Cresselia does not share any effects with Dialga or Palkia. There are two effects that Cresselia can cause, both of which are attacks:
Stage hazard switch
In Ultimate, when stage hazards are turned off in the rules, this stage has different functionality. The two soft platforms do not move, remaining fixed at their halfway point. Dialga, Palkia, and Cresselia can still appear, but they never cause any effects.
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 Final Destination and Battlefield, 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.
Spear Pillar is the location of the two Legendary Pokémon Dialga and Palkia. Team Galactic, a criminal organization which operates in Sinnoh, travels to Spear Pillar to awaken Dialga/Palkia and bind them by a Red Chain created from the crystals of the lake guardians, Uxie, Mesprit and Azelf. Team Galactic's goal is to use the Legendary Pokémon's power to recreate the universe with Cyrus, 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.
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.
